ecm question

since i'm getting no reading from my new scanner and believe my ecm is bad i'd like to know if any other ecm (camaro etc.) would work on my 1985 or does it have to be '85 vette ecm as my friend has a junk yard and told me to let him know before buying a new ecm. also if that's the case would it need to be reprogrammed.........rsvp

Match the GM production number off the ECM. You can get good quality rebuilds just about as cheap as used. No reprograming done on that ECM, all done witha prom chip, also would need to match GM production number. I would get the prom from GM, because you can get the latest updates already burned into it.

i tried my local chevy dealers and no luck on the eprom or rebuilt ecm. any suggestions on who to contact, also as i stated before i'm getting no codes or flashes with my new code scanner just the service light stays on, so again would these items need replacement or should i try an actual shop computor scan before buying them as i'm new to corvettes and making every effort to learn them, i just bought this 1985 from an auction for $3500.00. starts great, sounds strong but dumping that fuel on 8 cylinders and can't scan for the codes to find out why.........HELP PLEASE

Try your local Carquest store. Have you got the number off the PROM? GM should have it or can get it. Get me the number and I'll check. It might have been updated several times.

i just pulled the ecm, the # is 1226870 for the ecm, is the prom the chip that snaps in and out of place where the little cover comes off of the ecm

Yes, it is. Be careful pulling it out and putting it in. It is easy to bend the pins if you don't have it in properly. I need the GM production number off the PROM.

these are all the #'s, first under neath when i pulled the chip JT8(G)/J6/P LFIVZ893 AH01 second, on top of the chip is, delco HLP is all that i can see, although there are some more #s on top but can't see them due to the surrounding black chip cover

There usually is a sticker on the PROM with the 4 digit number I need, but I guess over the years, it has disappeared. I will try tomorrow to get you some answers.

Attached a prom ID picture.

Is your Corvette standard or automatic?

Have you checked powers & grounds to PCM?? That would be the first step on a no comm. (Ck wiring diagram)
