Has spark and fuel pressure, won't fire.

suprchrg'dstang · 12-15-2009, 09:12 PM

Been awhile since I posted, but the combo has changed a bunch since I started. I just rebuilt the block and added lots of goodies. it is turbocharged now and I had just finished everything(over a month to finish) and had the car running with the old 76mm C&L MAF. My buddys friend is a tuner and flew in from California last week. They were driving it around the block a few times. Well something took a crap. Now the car cranks but wont fire. It does have spark cause I checked that. I can here the fuel pump prime and fill the fuel lines. Timing was set when it was running when I left the car to them. I haven't replaced anything but the spark plugs. I cleaned the distro cap and had the module tested. I mean if it gets a spark then its not electrical is it? I just dont wanna start throwing parts at the car for no reason.

-This car has no emissions
-IAC has less than 5k miles on it
-Fuel pump is Walboro 255lph less than 5k miles
-FMS 42lb injecters less than 2k miles
-Accel 300+ ignition and coil less than 500 miles
-ABACO MAF was sent w/ 42 lbs tune already on it by Anderson FMS

Thanks for any help you can give, I lose sleep over this thing not running...

well if your sure its sparking then prolly not a ign mod. i know you said fuel is comming out but u shoud still check the pressure to make sure its good just to rule that out.a few other things to check out would be compression.maf sensor, usally if there bad you can unplug the maf sensor and it will start.let us know what you find or if u need more advise

Was the distributor pulled out and of so , are you sure you didn't stab the distributor in 180 deg out of phase ?

TDC on the compression stroke ?
