Well, the only thing that I can suspect is the injectors, and my 550s are new so I decided to go crazy with it and put in 1000cc secondaries with upgraded fuel rail, Aeromotive FPR, and also Greddy Profec Spec II since an EBC was long time overdue. Anyway, but I've been shutting the car off by fuel pump switch every freaking time... could it still be my secondaries leaking and dumping fuel as soon as I turn on the pump again? No fuel could flow if the pump is shut off, right? If it is not my secondaries that's leaking... oh god will I be pissed. Anyway, I would appreciated it if experts could chime in here and give some inputs about this. Thanks in advance


EDIT: Oh, BTW, the car would almost start... but it doesn't. If I were to give it any gas, it would just die. Sometimes it would stay started, but then again, same thing. Tough the throttle, and the car dies. And it idles like **** and barely stays alive even if it does start... and even if I don't do anything, it just dies. I tried unflooding(spark plugs removed, cranking it several times to get rid of gas, and clean spark plugs and put them back in), but it didn't help at all.

Are you sure it's actually flooded? It sounds a bit like a huge vac leak to me...

It's flooded for sure. I was able to get it started on Sunday and it ran just fine while warm... started right back up, too. When I was unflooding it, I saw smoke of gas from engine escaping through spark plug holes and could clearly smell it from exhaust pipe when I was trying to start along with smoke...

bump.

Well... got my car back, and it ran fine. However, it smoked a lot although AF ratio was fine. The smoke was definately fuel I think though... and I took the car to my dorm, I let it sit for like 3 hours, and then started it, started up fine, and I drove it home to VA from OH. The car started fine after fueling... so I came home, let the car sit for like 10 hours while I slept and got some rest, and I tried to start it up again, but it started up and died right away. So I tried to restart it, it started so I gave it some gas and it stalled right away, and I couldn't start it after that. I tried to unflooding procedure, and it didn't help starting the car. I got 1000cc injectors in with Aeromotive FPR since RX-7 Store thought that the secondaries are leaking, but that doesn't seem to be the problem since I still can't get it started. I need help...

Also, do anyone know a good shop in VA? I know there are Rotary Revolution and Rotary Performance... are those shops any good?

Thanks in advance for your help

Oh... and I always turn the car off by turning off the fuel pump if I know that I'm gonna let it sit for a while... I did so and that didn't really help I guess... I really wonder what my problem is... I checked to see if I'm getting spark and it was fine... I'm really stumped here...

A long shot here.
You have 1000cc secondaries. By any chance, could you switched the sec. and primaries wires? I can't believe RX7 Store sold you something that's not even related to your starting problem. The secondaries doesn't even come into play. A FPR isn't even required on a moderately modded engine.
Anyway, that's just a guess.
If you have 1000cc in your primaries (wires switched?)and no fuel controller, you will flood.

Well, thought that my secondaries were leaking and dumping fuel, and I wanted to upgrade my fuel system if I'm gonna changed my secondaries anyway since I'm gonna shoot for around 350rwhp @ 15psi. I do have Microtech to tune everything, and I doubt the wires are switched... I just don't know why it wouldn't start because neither me or RX-7 Store can't find anything wrong....

Rookie84

I unflooded the car and put it new spark plugs... I was able to start the car. I killed it by accident and it started right back up. However, it was tough to rev as if there were still too much gas in the engine. My car seems like it will flood again at any given time... Well, I still need to figure out why my car is dumping so much fuel.... ARRGGGGG.... any inputs? Come on guys, I need some help here!

Just a thought. Coolant temp and Air intake temp data help set A/F values at start-up. You indicate probs only at cold start. Check MAF and connector at MAF before next cold start by a sharp whack on top of MAF and by discon/recon connector. Also wiggle test CTS harness and connector. Computer may think its -40F at start-up and loading massive fuel pulse. Good luck.

No MAF for me... I'm running Microtech. Thanks for the help though
