New guy here looking for some help. I have a 96 camaro z28. I’ve had the car for just over a year now. The car ran great would start up great and over time it started to not crank but then would start up and ran great. It eventually started struggle even more with start ups then would back fire when driving. I had a shop check it out and got a new fuel pump, spark plugs, wires, and cleaned the injectors. Was tested and was getting the right amount of fuel. I picked it up and it was driving ok. I got a couple backfires then they went away. Not too long after I did a pull in it and it ran good then the second pull as soon as I floored it the engine completely died. Lost all power. Wouldn’t turn over or crank. After this I replaced the starter, the optispark, and cap and rotor. Still nothing. Not crank no start. Any ideas? Thanks

 

Did you ever scan it for codes?

Have you checked the fuel pressure at any time?

Do you have spark when the starter is cranking the engine?

 

where did you get the "optispark, and cap and rotor."
