I’ve got a 1995 k1500 with 7427 ecm. I am using a Moates g1 adapter with a 27sf512 eeprom.
I pulled out of my shop last night, and the truck hiccuped, I pulled into my driveway and it died. It would not restart.
I noticed the SES was flickering, so I pulled the chip and swapped a backup 27sf512 in, all was good.
I reburned both chips, and tried them both, and had no issues.
This morning I started it up, and I didn’t have the Prom verify ses flash, and the truck wouldn’t start.
I swapped another Spare 27sf512 and the truck started and ran fine. I drove 2/3 miles down the road and the SES lights flickered, and then went on; the truck went into limp mode, I limped it home and parked it.
The only thing I have changed on the truck; I’ve put led lights in the dash, and swapped back to the original alternator. Alternator charges just fine and no other issues.
thanks- Aaron
