Hi guys, Im having a difficult time pin pointing the starting problem on my 1999 Camaro. I recently replaced the battery, fuel pump, alternator, crank position sensor, zzp coil packs, along with a truck starter, and still have no luck with getting it to start.
The car also has a Btr Stage 3 cam with upgraded rockers. Im not sure if there is a ground problem, or my cam position sensor has gone bad or what. Any info would be greatly appreciated, thank you!

 

Not a "ground problem" except that the negative (ground) batt cable might be too small for the amount of current the starter motor wants.

Try larger gauge batt cables. Both of them

There are several "truck starters". Not sure whether the stock LS1 starter is the same as any of them. The 4.8/5.3 one is MUCH smaller than the 6.0 one. Also not sure whether a newer 6.2 or some such one would fit. You definitely DO NOT want the 4.8/5.3 one.

 

Is it an actual STARTING problem, or a CRANKING problem?

 

If you bought a cheap cam sensor on Ebay . . throw it away and get a good one . . I bought a cheap one on Ebay and it didn't work at all.

 

I meant crank sensor . .
