I was driving down the road when all the sudden my temp gauge started acting like the tach. I shut my car off and now it wont start back up.
The oil and CEL lights are very dim, but all the others are good. I hooked it up to a battery charger and no change. The cel light will come on, but very dim and not for the correct length of time. Then there is a buzzing sound from a grey box next to the interior fuse block.
Any ideas?

 

I think that grey box is the main relay. Would that cause the problem described?

 

Possibly, if the box, [PGM-FI Main relay] is buzzing there is a problem, either internaly or a poor ground...

Problems with the PGM-FI Main Relay are common, but almost always easy to fix...

Good luck. 94

 

I replaced the main relay and now there is still no CEL, no 2nd click, and when I go to start it, it turns on the radiator fan!?!?!!
I am stuck at this point.

 

You got it exactly!
I replaced my clutch a few days ago. The ground wire from the passenger side to the transmission was loose. Once I tightened that up everything started working fine again, started right up.
Thanks!

 

...and now it bogs and hesitates trying to get over 4K RPM. I think I screwed something up running without the ground cable tight.
I reset the ECU with no luck.

 

I must have damaged the original main relay when the ground was loose. I put the one I just bought back in and it runs fine.
Fixed....for now....
