I’m absolutely stumped, I’ve been wrenching on this car for a couple weeks now and z i’ve fixed alot of the major problems I’ve rebuilt the clutch and the breaks fixed the shifter changed all the fluids, I’ve even checked compression and it should run beautifully. However, one problem stands in my way. It won’t crank! i’ve replaced and checked all my fuses and relays and im stuck. What’d the checklist so should go through of what to check and how do I check it? anybody with any knowledge or suggestions is appreciated!

 

Is the immobilizer active? Sometimes the security system looses the programming for the key

 

I did just get the key reprogrammed but who knows. there’s a great post in here that tells you the immobilizer flash codes, so far inconclusive.

 

Also try starting it in neutral... sometimes the clutch interlock switch will keep it from cranking
And make sure you put the solenoid wire back on the starter... mine fell off once at the track and it won't crank like that either

 

+1^

Corroded ground wires also.

 

tried that one i thought that too good idea though

 

How do I correct that i’ll be the first to admit electrical is not my strong suit. do I need a new wire harness or to Sauter new wires?

 

checked all the starter wires all good, however there is a connector by the transmission with no apparent place to go I’ll send a picture but i’m not sure

 

This has pics of ground wire locations.

thanks cajun

 

I’ve looked on wiring diagrams for hours bo clue what this is or where it goes could it be cuasing an issue?

 

Thats the rear O2 sensor plug...

 

that would plug into my CAT right?, which I am missing, that wouldn’t cuase a cranking problem right?
