Im working on a 1992 GXE and it sat for a while but now it wont start. It will turn over just fine but not fire up. If I remove the green starter relay from the fuse block next to the battery and jumpper a wire accross it it will start. Where does this relay get its signal from to connect? Any help would be great.

BTW I did replace the relay with a brand new one so I know its good.

 

I would have to figure it would be the igniton is where it gets its signal.

 

That's actually not a "starter" relay. It switches power to some ECU pins and other crap. The coil is grounded by the ECU. If the car starts and runs fine when you jump the connector, it means either the relay is bad, or it's not receiving the ground signal from the ECU. The coil receives 12v from the same source it switches, so I doubt the coil is lacking the +12v, more likely it's not getting the ground signal. Grab a multimeter and make sure.

 

Have u resolved this issue and if so then share your findings for us to read(interested). You never know who this could help in the future.

 

Agreed! I've learned and saved so many dumb/ repetitive question just cause someone else has asked & resolved the issue already.

 

I have not resolve this yet, it's a friends car so I'm waiting for him to come up with money for repairs. I will certainly let you know when I find the problem.

 

I thought I had a bad relay there as well but I did not. The relay coil gets energized to ground thru the "security system" which disables starting of the car. Replaced that relay and no difference. Jumpered out the contact in the start circuit and that would work-sometime. Also found the coil wire that went to the security system to get grounded and I grounded that wire to energize the relay, but again, that had mixed results. I am starting a new thread about my problem.

 

Have had similar problems, but will post a new thread about it.
