Fuel pressure 45 lbs and holding steady. (Fuel pump replaced recently due to freeze up failure)
Good injection pulse on all injectors (checked with noid light).
Good spray from all injectors (standard check with strobe light)
Good spark from all cyls. (Nice blue and hot gapped to.50)
Compression 150 to 155 lbs across
All back tracing voltages correct including the icm and coli harness.
vats system has been bypassed with correct resistor (plus vehicle would not turn over if there was a failure)
No start with carb spray directly into intake.
No codes present ( dug out my old mt2500 brick for this one. Had to make a harness to connect obdll outlet to obd1 connector. Another great GM idea, put an obdl system with an obdll plug).
have the same problem?
