Heres the background. Installed T3 turbo, intercooled.... 255 in take fuel pump 450 injectors and VAFC.... Running 6 psi of boost.. Car ran fine for about 10 mins and then pulled up to a stop sign and car just sputtered a little bit and stalled then it wouldn t start back up... No codes are being thrown from the ecu.. Pulled the plugs and I was not running to lean and they are not fouled. Did a compression test and all cylinders checked out to 190... Any ideas??? I am baffled and everyone that has looked at it has no clue!!!

check your wiring for the vafc. what are the settings?

CRXLST

I checked the wires.. They look good still they R soldered in.. I had it lean 15% 1000-4000 10% 4000 and up... That is how they told me to put it until I got it 2 the dyno... But it didn t make it.... LoL I am baffled never heard of anything like this B4...

you should be in the negative percent, not the postive, if you are running 450's. i had -38 to -35 for my setup.

are they the right ohm inj or running resitor box maybe burnt out inj drivers in ecu

CRXLST

I have resistor box wired in... And yeah I am running - % ... I was running the resistor box for about 3 months now... I am not throwing any codes on the ECU.. I am going to check the fuel pressure 2morrow...

CRXLST

think that maybe the car just flooded and that is Y it wouldn t crank back up???

is the fuel pump priming?

crispydee

set the afc to like -38% and see if it will start then. Next listen to the engine at idle slowly adjust the afc so that the engine sounds happy and is smooth. It should be between -35 and -40%. Now set it 1 or 2% rich every 1000rpm's after 3000. This should get you safe till you can get it tuned.
Also incase you forgot.... you did retard the timing to atleast 12 degrees btc instead of the stock 15 odd

CRXLST

yes I did... But I dont think i retard the timing enough... I ll give it a shot now.. Fuel pump is priming.. I am just going 2 try 2 get it 2 start and if it does it is getting towed to a DYNO...

that happend to my old set up, i switched back to the stock fuel pump and no prob after that. maybe you need a fpr or something.

CRXLST

Well I pulled the plugs out and the top of the cylinders were wet... So it was WAY RICH!!! I got new plugs and I m just gonna tow it 2 the dyno so they can tune it with a wide band... I ll post my results as soon as I get them...

Just set the acf to 35% across the range and drive it off boost there. It should still be rich but should start at that.
