Went to start the motor one day. Would turn over, wouldn't catch. Juggle the throttle and it will run a tad but blow white smoke and then die as soon as you stop juggling the throttle.
Did a compression test, came out a reverse bell curve. Bad headgasket? Took the head off, it was cracked. 0630. Cylinder walls were smooth so I had it sent for a hone, they had to bore thirty over.
Get it all back together with a reman'd odessa head and new everything else. Full rebuild, no corners cut. Does the same thing, just with good compression and less worn motor.
Cranks and cranks and cranks.
New CPS so it's not that. New cap, rotor, wires, plugs, coil, all fine. Timing gun on wire #1 shows we have spark.
Fuel is at 48ish PSI on the rail. Jumped the fuel relay and fuel valve on the rail and it will push fuel just fine. Spray a ton of starter fluid in the throttle body and it still wont run.
This leaves me to believe it is clogged injectors, or electrical. Bad ECU, sensor, ground. I'm out of ideas guys.
