400sbcVette
Member
I bought an 86 Vette with a 400 ci swap with the original TPI still on it. The guy that had it said he drove it around alot and one day he had it running outside his shop and it simply quit. He thought it might have been the fuel pump, so he replaced it. It runs for about three glorious seconds then shuts off. I've gone through and checked/changed a few things and nothing is different. There are No Injector Pulses to the injectors. Here are a few of the things I have done:
Ohm'd the injectors. They are all at 16 ohms.
Checked computer grounds. They have continuity.
Changed distributor/pickup coil.
Checked for fuel pressure--it's got good fuel pressure.
It has spark.
I checked the ignition switch at the plug for the VATS. The multimeter registered the proper ohms for that key in the wires.
I've got the reference voltage coming from the distributor down to the ECM harness (The purple/white wire).
Is this an ECM problem? Just need some advice on a few tests I should do, so if you guys have anything, let me know.
