Okay, as my last thread, I wasnt getting enough spark, and i found out it WAS my spark plugs.

After putting my new NGK's in, it fired right up first try, BUT I could hardly touch the throttle, if I did, it wanted to die, i could only get it to about 1.8k at the most...

After I let my car warm up, I turned it off it let it sit for about 1 min. After the cool off, I tried to recrank it and it once again did NOT won't to crank...

SO, me and my bro, looked at the plugs like we always did after everytime we tried to crank it...

Well, it turns out that, THERE BONE DRY!! =/ usally they have some kind of fuel on them, even just a small amount...

SO, my motor now WON'T get ANY fuel into the motor!! =(

We took off my upper intake manifold and checked out the fuel injectors and rails...

Fuel IS passing through the lines, making its way through the fuel rails and into the injectors, but its not getting past that point, and there ALL GOOD!

We tested every injector, they all passed go! =/

SO, we assume it has to deal with a resister, or some kind of emission...

I am TEMPORARALY using a N350 ECU (my motor is a S5 13BT)

WHATS WRONG WITH MY CAR?!?! =.(..

Btw, No Leaks!!

And, Usaly When We Take The Plugs Out And Let The Gas Shoot Out Of The Motor, Not A Single Drop!

 

From HAILERS:

"Hold your spare CAS in your hand with the CAS connected to the harness.

Key ON, Engine OFF. Spin your spare CAS by its bottom gear. Listen for the injectors clicking.

Disconnect the Lead and Trail coil assy's before doing so. That way you won't mistake the click of the sparkplugs for the click of the injectors.

No spare CAS? If you KNOW how to install the CAS right/properly, then remove the CAS in the engine and do what was described above.

Sure it's not flooded??????????????????????

Or pull both Lead plugs out and everything else connected up. Have someone spin the engine over for a half minute. A fog of fuel should exit the sparkplug holes.

Does your tach needle bump a bit when your starting? Should if the Trail coil assy is sparking the trail plugs. The bump shows the trail coil is at least working, and that the CAS is outputting, which in turn makes the injectors operate. Something like that."



Dunno if that helps, but the guy there sounds like he may have a similar problem

 

awesome, thanx man. ill give it a try, and btw, yes it use to flood because of weak spark untill i got new plugs, and we use to take them out and let the puff of gas shoot out of the holes, i mean, everything is working just dendy, but now its just not putting fuel past any of the injectors...soooo, i mean not everyone one of my injectors all just suddenly went dead on me lol...

somthings holding them back...but ill still give it a try haha =]

 

is your EGI fuse IN?

 

yep, we never took it out. maybe we blew it???

 

You say your not getting fuel PAST the injectors? The car won't rev? And now it won't start?
Sounds to me like your not getting enough fuel and the car is choking out when the demand goes up. What's your fuel pressure lookin like? Out of curiosity check to see if the filter is clogged, and check the pump to see if its working.

 

nope, no fuel past the injectors, but its pouring fuel through the lines and rails...the pump is fine, its a brand new walbro 255...

and i dont know what my fuel pressure is atm...

whenever i wasnt getting enough spark, i could rev it to about 4,500rpm.

now thats i have good ingnition, i have no fuel getting into the motor lol...i mean, i assume the pressure is fine, it wants to pour out like absolutly nothing is holding it back.

if it wasnt raining, i would try looking at my dampers..maybe that has somthing to deal with it...i have no idea realy, but there arent any leaks what so ever...

 

im currently going through the same deal with my jdm swaped s4 fuel to the injectors but not past that. its weird.

 

never assume that there is pressure.test it after the filter.should be minimum 35 psi when the system is primed.

check the walbro as well.if you have a S5 the module is kinda weird to assemble,you slide the spacer then o-ring then cap onto the pump it self then you slide the pump into the module,ran into the same problem a few weeks ago,the o-ring didn't sit quite right and was getting 10 psi when primed.get a pressure tester to confirm that there is pressure.

 

Exactly, Fuel coming out of the hose doesnt mean the right pressure is there. Check it. Assumption will bite you in the end.

 

..Well my Reasoning for the EGI Fuse is that you Have fuel To the Rails,but No Fuel in the Housings,as you said the spark plugs were dry..QUESTION: did you Take the Fuel Lines OFF The Engine?.and IF you did,are you sure they are On Correctly?(anyhow..I would Recheck that FUSE..you could have Popped it when you Took the manifold off)

 

When you check the fuse, test it with a meter. It can look good but still have a hairline crack.

 

alright ill give that a try, its been cold here latly and my bro and i are waiting for it warm up alittle more before start looking at it again, but that helps soooo much for all that info, ill let yal know how it goes..

Yeah, i mean, all of the lines are fine..

let me just explain better of what exacally happend:

I wasnt getting enough spark...new plugs...cured it...after it started, like last time i started it with bad spark, the idle was jumping between 1k and 1.5k rpms...

but this time, i couldnt give it but a hair of throttle, to just ease it over 2k rpms...once i killed the motor after it warmed up, we tried to restart it and it wouldnt, so we checked the plugs and they were dry, so we were like ****, now what?

now its not getting fuel past the injectors, so it might very well be the pump or my EGI fuse..but yeah, ill def. give it a check and tell yal how it goes =]

 

Do our cars have a fuel injector resistor? If so you may want to look into that, it may be they just aren't working properly...

 

yeah they do, but i cant find out where it is =/

 

Me neither... I can't get the freaking FSM to work today for some reason... Anyone else having any problems with it?
