I would want to say a fried ecm. But that wouldn't really explain the speedo as that is controlled by a cable going directly to the tranny. Still, it's prob a computer problem.

Hey guys ok a lil more info would b nice but I did a little research and code 20 is eld and everyone says it's in the fuse box under the hood and they say if u replace it the code goes away well I replaced it and it's still there also I switched to my pg7 ecu (87 teg) and I still get the code 20 I'm thinkin it might b my alternator but I had it checked and it pits out 13.06 steady im in need of some help guys

Did you buy the car with this problem or did the problem start happening after something was worked on?
Did you ever have the cluster out?
Is it a cluster swap?

hatch_kidb18b1

I just got off the phone with the previous owner he said it was like that when he got it and didn't try to fix it he just parked it. It's the stock cluster and the last time I had it out was back in 05 when I first owned the car and it was out to replace speedo cable and i didn't have this problem then

So you didn't have the problem in 05 when you first owned the car.
Did you sell it and buy it back and now it has the problem?
OR did the problem just start recently?

If the problem just started recently, was there any work done anywhere on the car where the cluster was fine before and then this problem after?

Was the engine or interior harness worked on EVER?

hatch_kidb18b1

A new motor was swapped in that's all the info he gave me he said he bought it from the guy I sold it to and it was like that when he bought it and I noticed there r some cut wires on the engine harness and I can't find where the wires go the problem was not present when I first owned the car

Omg really so I had a hunch so I put a piece of speaker wire to the negative on the battery then grounded it and what do u know everything is working correctly thanks guys so much
