So I installed my new secondary injectors last night and also replaced my fuel pulsation dampener due to slow leak. I took my time and worked very meticulously got everything back together and started the car. After I started the car it just smokes and smokes. The smoke is like a thick mixture of oil and fuel. I just do not know what it could be. I have done jobs like this many times and im confident that its something simple but what? I now am honestly considering selling the car once I figure out the prob. Im just so over working on it, a year and a half, probably about $6,000 in new parts, labor, and time troublseshooting with no progress towards having the car run correctly. Hell, I have even driven the 10 hour trip to Pettit twice w/no A/C but didnt help. So, I believe its time to move on possibly, not for sure but im over it. And dont think that im just some kid that did not put the car together right, everything has been done correctly. You guys may not like Pettit for whatever reason but Cam is one of the best at troubleshooting these cars and he even said that I had done a great job in putting this car together. But, even still I have recieved no fruits for my labor, or money. Fd's are the biggest pain. Sorry, just needing to vent im so frustrated.....

Thanks Jamie...

Sorry to hear of your frustration !I purcased mine with 30k on it well maintained
and garaged took it to the Drag strip , Blew the rear, syncro's, and coolant seal
I removed everything had the engine rebuilt with a street port by Hayes, I re-intalled it with all new OEM parts Had No problems , My FD is Newer than New
and I don't beat on her . Kuddo's for hanging in there !

I also only drive her 500 to 1000 miles a year !

I really love these cars sooo much and have met sooo many people and so many experiences with the car. But when is enough, enough? ya know?

mibad

That blows. I'd be feeling the same way. Hopefully, some of the gurus on here can help.
Stock FPD? Injectors?
I don't know much about these cars. I've had mine since June. Just from my readings on this forum I've observed that LOTS of people experience problems after replacing or getting injectors cleaned. I'm not touching mine again until i have to!

Sorry to hear of your frustration. BUT, the car can be fixed. It's just a matter of having the patience and resources to figure out the problem. Mostly patience if you work on the car yourself. I personally enjoy working on mine almost as much as driving it. Yes, it is a pain in the *** when something breaks, but it's all about perspective......(opportunity or obligation). The good news is, that's your choice. And really, the only time it becomes obligation is if that is your only means of transportation.

yeah that is all true but I have been working to solve issues with the car for over a year and a half now but no progress has been made. Like ive said I even took it to Cam at Pettit, stumped him. Rob Golden from Pineapple, stumped. Nobody including myself can seem to locate the problem, so I think as soon as I get it back to running the way it was without smoking, which is probably a vaccum line somewhere. Im going to more than likely sell to get the g35 coupe I have been wanting. So, if you know anyone looking for an Fd that has just about everything that can be done to a twin turbo setup, let me know..... There have been no expenses spared on this car, everything on the car is the best, paint is custom, wheels are Blitz, aero is Veilside, I mean everything is the best....

Thanks, Jamie

do you mind posting some pics of the car and a mod list? im sorry your having this problem with your FD. hopefully it doesnt take much to get it back to normal. if you find yourself putting even more money into it and not fixing the problem, i would consider taking it off your hands at a non-running reasonable price. good luck jamie.

I could straighten it out if you were nearer to me...

g35c for the win

Well the car runs fine but I have issues with running to rich while under boost. Right now im under the hood trying to find why its smoking after putting in my new secondary injectors last night. I believe it is probably just a mixed vaccum line. Level7, the car runs great just under boost for some reason its richens up enough to make the car run about -80 hp from it does with the right fuel mixture. The engine was built by Pineapple last year, stage 2 w/about 6,000 miles on it. The turbo's replaced at the same time with the 99 spec version turbo's from Mazdacomp. Mods: pettit intake, m2 dp, m2 ecu, 99turbo's, new stage 2 motor, 20b fuel pump, flowed and matched primary injectors, new secondary injectors(as of last night), fluidyne radiator, greddy bov, turbo timer, c's short shifter, random tech. cat, greddy power extreme exhaust, airpump eleminated w/greddy pulley kit,polished intake piping, Pettit AST, Magnecore wires 10mm., with NGK 8&9 plugs gapped, full Veilside c2 kit molded with custom ruby pearlescent paint job, Blitz type 03 wheel-fronts are 18x9.5, rear are 18x10.5. three gauge pod on A-pillar w/VDO boost, water and oil temp. gauges. Tanabe sustec springs for suspension. Vaccum hose job has been done w/hose techniques supplies. Im sure that there are some things that I have forgotten but you get the picture, I have at least $30,000 in upgrades in all. The car in my avatar is my car, I will try and get my camera back soon and post some for you...

thanks, jamie

Kevin, I wish you were! I have been really disheartened in the past when I took the car to Cam twice and he could not figure it out.WTF!

Does cam not have a wideband for troubleshooting? Other parts to swap on for troubleshooting?

DVSseven

Yes, he does that the thing. I went down there not knowing what was wrong with my car. We were able to find on the dyno that it was dumping fuel under load. So, after we found that I left the car there for a week while I went to Disney with the fiancee expecting him to be able to find the source. A week later I return and he says that he is stumped, says he had Steven kahn on the phone, mazdacomp, and some other guys but no-one could help him and that he did not anything else to do. He recommended replacing the full engine wiring harness, and I did and it did nothing. Hey if you need a vacation here in Panama city Beach, i got an extra room a comfy garage etc. here on the beach. You could come help me sort this thing out and in turn get a free vacation and cash in the pocket....

Yeah but then I wouldnt have my tools and parts and such to work on the car, so I'd be pretty useless

DVSseven

ive got plenty of tools, i work for Mazda...

put an ls1 in it problem solved.

I'm voting mixed vacuum line. It really tests my patience, but I often get them wrong or forget to connect one.

Did you start with an unflood?

Is the massive smoking during startup/idle, or when you're on a test drive?

Dave

DVSseven

At idle, I believe a line as well. But may be a mixed connector on the rats nest. I need a real life colored diagram quickly.. Or how to know which color goes where...

dgeesaman

iTrader: (7)

It's easy - the solenoid connector branch starts near the firewall, and each connector goes to the next solenoid all in a line.

So from back to front, the rats nest connectors are: orange, blue, grey, yellow, brown, white, green, and the black connector goes to the one that sits on top.

No doubt about usefulness of color diagram printed out big. I could send you one, but it'll take a couple days to get there. Maybe you can take the color diagram and have Kinko's make a color 11x17 copy for a few bucks.

Dave

thanks dgeesman!!!

Fu*k an ls1!

Has it run properly at all since your rebuild? If its not a vacuum hose switched I would think about naybe getting a stand alone... But I dont know much about the M2 ecu.

DaveW

I made one of the vacuum-hose schematic (took the hint from Dave G) when I did my hose job. What I did was to divide the large photo of the diagram into four sections (each 8.5x11) by cropping and saving with a new file name. I printed them individually on regular letter paper. I then used spray adhesive to attach them to a piece of poster board to get one large diagram ~17x22.

Check the vacuum lines to the pressure regulator control solenoid, the one closest to the firewall. As the name implies this solenoid controls fuel pressure, if the solenoid or wiring had a short or open it would keep pressure at 41 psi. If its vacuum lines were crossed with some other solenoid, I assume the fuel pressure would be either higher or lower depending on what the source of that vacuum line was providing.

For example the solenoid (2ndary air bypass valve/ relief 1) closest to the regulator control solenoid is operational either before or after approximately 3,200 rpms I know this is somewhat vague, but I don’t recall exactly when the solenoid is operating. That particular solenoid can also cause richness.

was waiting for someone to say that.. But why **** the ls1? lol

So, I Took The Uim Off Again Last Night To Find Out Why My Car Was Smoking From The Exhaust After Replacing The Secondary Injectors, And The Fuel Pulsation Dampener For A Fuel Leak. Only Thing I Really Found Wrong Was That The Double Throttle Vaccum Hose Was Off. Other Than That I Did Not See Anything That Was Out Of The Ordinary, So I Put It All Back Together And No Smoke, So Yay!, I Hope That All Is Well. Then In Turn I Took The Car Out For A Ride And The Car Seems To Pull Like It Should Now. I Have Not Done Many Pulls On Her Yet But I Thinking And It Appears That I May Have Taken Care Of My Performance Issues. Before The Secondary Injectors I Was Running To Rich And The Car Would Not Pull While Under Load. The Car Was Down -80 Hp , Per Cam At Pettit While On The Dyno. So I Believe That The 2ndary Injectors May Have Solved The Problem. Now After I Shut The Car Off I Have A Very Small Whistling/gurgling Sound Coming From Under The Uim. I Have Checked All Of The Water Lines And There Is No Problem With Those, And In The Area That Sound Is Coming From There Is No Moisture Found. Boost Pattern Is Fine And There Are No Leaks That I Can See. Any Idea What This Noise Could Be, Vacumm Line? By The Way The Idle Is Fine As Well.

Thanks, Jamie....

Don't worry your not alone in this frustrating "fd" journey. I have spent lots of money (substancially more than $6000) on the car trying to get it to run right. I too upgraded the secondaries but went with the 1600cc ones and a new fuel rail. At the same time I did the sequential simplification (I run a Power FC). So I put the car back together and wham the sequential system doesn't work. I retraced the vacuum lines (now there are 14 or so) and it still didn't work; soo I just did the poor man non-sequential mod. 2 months later I blow the primary turbo so I just bought a single turbo, now have 5 vacuum lines and hopefully it runs better than before.

Just hang in there. Nothing is more satisfiying than a proper running fd.
