I have a 1992 TPI set up in my 76 Chevy Pickup.
I had an issue with my alternator a few days back. It was back feeding and my A/C system was hot with key off. I changed the alternator and now I get cranks with no start/cranks with a few seconds starts and dies syndrome.

Code 46 is coming up after resetting ECM with battery disconnect. I had a code 51 with a stuck on CEL earlier also.

I found my in line VATS resister and it OHMs out fine.

Anyone have any ideas?
Did my alternator problem fry my ECM?

Thanks,
Pugsy

 

Bump.

Anyone have an alternator issue toast an ECM before?

 

I got the VATS bypass from Baker Electronics and she started right up. It died a short time later so I swapped from the blue wire to the green wire (30 HZ).

I joined the wire to the VATS F10 wire but did not cut it. Not sure if this is correct or not.

I think it's time to order up a chip/ECM? with VATS disabled.
If this aftermarket module fails, I'll be stranded somewhere.
