Problem I believe was caused by low voltage issues. Replaced battery and car just turned over fast without spark. Ran fine before weak battery issue, Also not showing RPM on hp tuners while cranking over. I am guessing maybe crank sensor?? I have one ordered and will try that first. Car is a 98 SS full bolt on cam-only with spray. Tested timing tuner and it's fine. Any suggestions would be appreciated. Thanks.

 

Were you tuning the car on a weak battery?any codes stored?also have you tried a vats relearn just in case?

 

Nope, wasn't tuning. Car was running fine. Battery went dead from not being driven/started often. Charged battery, car barely started but rpm were up and down, so I installed a new battery and car just turned over fast with no spark.........

 

Any Ideas?? Anyone?

Lol.... Not yet. Its ordered...

Check all of your grounds. This may cause both your charging/low battery voltage issues as well as a no spark/rpm problems.

 

All grounds seem to be ok. Thanks for the reply.

 

Have you tested for spark? Do you know if you have injector pulse? Have you checked all fuses and fuse links? Do you get any codes?

 

Getting no spark. All fuses, relays, etc seem good. No codes.

 

Do you have injector pulse?

 

I'll check.

 

Did you ever find out what it was? having this same problem?

 

This has been a crank sensor or crank sensor wiring problem every time I've encountered it.
