I'm at my whits end. Any and all help would be appreciated.
Thank You

 

Checked all fuses and relays?

Changing system working correctly? Or can it idle without running away to check?

Battery connections, grounds, etc?

 

Thanks,


Will Idle for 1 minute. then it starts surging.i have to check the charging system in the morning. Battery's are both good, no corrosion I checked 5 or 6 grounds loosed & tightened.
Still Have to check out the relays & Charging system.
Thanks For your Help it is greatly appreciated .

 

Two things I can think of are removing your serpentine belt or removing the alternator fusible link. I wouldn't do either for long. I'm sure someone will chime in on whether removing the fusible link could damage anything (from the alternator not having a connection to charge with).

 

Disconnected the alternator, I have the TPS set correct, Same surge, I believe there might be a short for the ECM ot the ECM is bad. Thanks for you Help. Any and all advise is greatly appreciated.

 

Please help

 

Looking at the manual, the codes showing sensor issues do not have many shared grounds. Most are individual grounds to the ECU itself. It tricky to get to to, but have a look at the connectors to the ECU. Drivers side of the engine, mounted to the side of the block. I'm almost certain it is a ground problem, if not an ECU problem.

 

did the regulator ex but my voltage spikes up
