My friend was driving the car and he said it started to run bad he said he stabbed the throttle and after a second or 2 it shut off and hasn't ran since it has fuel pressure spark and injector pulse... engine was freshened up 500 miles ago new accel opti taylor wires at that time when you spin it over it pops out the exhaust lost on what to check next will not start on starting fluid just fyi

 

Sounds like a possible timing problem.

When the new Opti was installed, was the length of the cam dowel pin checked to ensure it engaged the index hole in the Opti correctly? Before installing, were the rotor screws tightened, with Loc-tite? Not unusual for the screws to loosen up and fall out.

 

I just slapped it in so idk about the rotor screws I'm kinda leaning toward that cause It is installed in the correct spot

 

If the dowel pin isn’t the correct length, or was not correctly in the index hole, it could have slipped. Is the SES light on? If the Opti is not indexed correctly, it can set a code for the crankshaft position sensor = P0335 or P0336. But it may not have set if all conditions for running the diagnostic were not met.

I've seen this happen. The engine was actually starting and running to the extent the owner did not feel the impact of the misalignment. Unfortunately, to verify the difference between the cam position sensor angle in the Opti, and the crank position angle (on the crankshaft, only for misfire detection in OBD-2) requires a GM Tech-2 scanner (or Chinese clone), and is beyond the capability of the typical basic OBD-2 scanner.

If the dowel pin is too long, it can press the rotor against the cap and damage both.

See first large paragraph here - from Shoebox:

4th Gen LT1 F-body Cam Install

The condition of the rotor is slightly easier to check. Screws could come loose, metal tip could have come loose, or rotor shatter if the RPM got too high.

 

The pin length has me wondering I know the opti would only go in the correct hole or it was far from going all the way back in place and I have a snap on zuse scanner if i can check the alignment with that I'll have to look tomorrow
