I was going down the road and my car backfired really loud, now my car will no longer start. The car tries to start normally but the engine will not turn over. Could anyone help me out here, I inspected under the hood and could not find out what is wrong with it. I filled my car up earlier that day so maybe I could have bad gas?

 

are you saying the engine will not turn over? or are you saying the engine does turn over but it just won't start?

 

Assuming the starter cranks the motor, You'll need a noid light, spark tester and fuel pressure gauge.

Use the fuel pressure gauge to make sure the fuel rail has pressure

Use the noid light to check for injector pulse

Use the spark tester to make sure the plugs are firing

If you have all 3 of these "ingrediants", it should run.

Is there a SES light?

 

I can turn the key and it will try to start but the engine will not go.

 

I have the same problem. I have replaced the Opti, spark plugs, fuel pump, still have the same problem. Opti cable, coil, module, and ecm have been ruled out ( these were swapped out of a running car). Still won't start. I have spark because it backfired once. All it does is turn over and stumble when you let off the key. Help please.

 

Yeah finding the problem is the hardest part, I dropped the car off at a mechanic (don't have time to fix it) and I'm just going to see if he can find the problem. If the problem is somthing small (like the Opti or coil) I will fix it myself but if it is the timing chain then the mechanic will have to do it (don't have the time to do it). If the mechanic cannot find the problem, any body wanna buy a non working 1995 Z28 Vert with 77K?

 

how much? I might be interested

 

3K maybe? First let me try to see if I can find out the what kind of problem I have. I use to brag saying my Opti has worked fine and is in top notch shape, those words may be ccoming back to haunt me.

 

I forgot the timing chain and gears are replaced too.

 

I had a 94 LT1 that left me stranded once. Turned out to be the crank trigger that fires the opti.

I've heard that is a common problem with that Gen Engine.

 

94 LT1 cars do not have a crank trigger. Engine position is obtained with the optical wheel pickup within the optispark, based on cam position.

In 1997 OBDII cars were equiped with a crank position sensor. That is why 1997 cars use a different timing cover than other years.

I'm guessing you were refering to the cam position sensor within the opti when you refered to a "crank trigger"?

 

Turned out it was the coil wire. The coil is corroded so bad the wire is slipping off. When I checked the wire it looked fine so I didn't mess with it but unless the wire is firmly placed on the coil it won't work. I have a new coil on the way and I need to figure out how long of a wire I need for the coil. I think the stock coil wire will be fine for a while, it is just the coil is falling apart.
