Express van 2500 4.3 vortec engine 1998 no start has 67 psi fuel pressure looks like compression is good fuel pressure stays above 50 psi when cranking [no start] took mass airflow oss throttle body left wiring on mass air flow sensor, sprayed starting fluid down throttle body did not even try to hit any cylinder. Seems to have spark but under compression I wonder it jumps plug gap on plug outside of chamber and I got bit a couple of times not shocked big time through my body does GM have a igntion. Coil problem like old style Chryslers had on there 318-360 engines v8 and the v6 engine 3.9? No codes as of yet in engine cotroler
have the same problem?
