Chevrolet Repair: 1998 Sonoma No Start No Codes, crank sensor, fuel pressure


Question
1998 Sonoma 4.3(X), AT, 4X4 won't start it cranks, fuel pressure is within 60-66
psi, has spark, no trouble codes, have checked coil, module, and crank sensor
no problem found, fuses all check out, not wanting to throw $$ at the problem
but at a loss what to check next

Answer
If you have spark and fuel pressure you must not have any fuel pulse I assume.  Are you having spark at the right time though?   YOu might want to check the distributor for a spun reluctor shaft.  The ring cracks on the spline and severely retards the ignition timing.  Does it try to start at all? Like even so much as a sputter? Have you checked for fuel pulse from the injectors?
