OK I was sitting on the edge of the freeway today due to another clogged fuel filter trying to get my car started to move it just a little further. I was cranking, let it sit to see if any gas could get through the old filter.. nothing. Well I finally decided to yank the old one off with bare hands and put a fresh one on. It starts and now my Tach/votmeter is stuck on the volt meter part and I have 3 dummy lights on, as if i'm trying to start it still. It will not go away and cant figure any of it out. 79 GS

 

Check grounds in the engine bay, then relays. I had the same problem, but Joe at Sportscar Performance ran mine down when they did the clutch...solved it completely...

 

Yikes.. did he mention where it was exactly? This really sucks cause I have to drive it still. It did it for a short time before I got back running, then went normal, after that I went to a parking lot and sat for a minute. Its been like that since though after i left there.

 

lol...I was afraid you'd ask that. He showed me, but it's been a while. I seem to remember that it was one of the relays that are attached to the driver's side fender next to the brake master cylinder...he cleaned the connections and re-installed them and my problem was gone...

 

Thats just my luck.. I used the last of my contact cleaner before this happened.. damn. I'm pretty clear on where to look now, thanks alot.

 

I dunno if this applies to early models, but 84-85 cars have a common ground for alot of stuff on the pass side right near the headlight motor. You can see the bolt with like 3 ground terminals there. Even the damn fuel pump grounds there. Dont ask me why.

 

Thank you Carl!!! my pump has been acting up and I jumped it to the hot side of the coil. new place to look.

 

If you wanna chase more gremilns, look in the factory wiring manual. Theres a pictorial description/location of all the grounds.

 

Ok this isnt a ground problem now, I dont know what it is but it is BS. What tells my car that its running so it switches back to the Tach instead of the voltmeter? please someone help.

 

Anyone?... this is bad, I think i'm gonna get a after market tach or something, and take the bulbs out for the dummy lights.

 

I had the exact thing happen to my 79 just over a year ago. It is the little gold colored box on the inside of the driver side fender area right next to the master cylinder. my dad replaced it and the problem went away. i cant quite remember the name though.

 

Yes I found this out last night, its the voltage regulator. Its like $28.
