Starter won’t crank (unless I trick it)
Hello,
Before you say”battery”… it ain’t dead. Twisting the key does absolutely nothing, everything works, just doesn’t crank at all.
However, If I take the relay in the trunk out, jump the fat (YE & YE/BK) wire leads, twist the key and the starter cranks away but the motor won’t start. The two leads to that activate the relay show no voltage when the key is twisted.
I had and identical problem when the computer under the seat got swamped (since been replaced) Took it out, opened it up and it looks fine. So does the starter relay (It’s just not getting V. to it). And of course checked the fuse, fine. I always a make a point of pulling electrical connections on and off a couple of times to assure a good connection.
The obvious choice is the ignition switch. But again, when I jump the starter relay, it will crank when I twist the key. According to my wiring diagram there is only one lead that is activated when the key is twisted to start. ALSO, the clutch switch is jumped, not an issue.
This has been an intermittent problem while I’ve had the car up for mods. (nothing that is related to this circuitry that I know of).
Ideas??
PK
P.S. Is there any sort of resseting that needs to be done if diconnect the batterey, like the windows?

Fixed It !!!! (Not exactly sure how though)
Poured over the wiring diagrams for hours, figure out where there should be voltages, weren’t there. Made some jumps here and there, got the voltages…still wouldn’t start.
Checked all the grounds, O.K. Id had the Motronic computer thing out (checking pin assignments for sc install) couple days before, looked like I’d put it back correctly, took it back out anyway & opened it up, solid state, nothing to do in there but damage.
Cleaned all the pins with a wire brush. Plugged the harness connector in and out a few times (helps insure good contacts). Buttoned everything in good. Twisted the key, resigned to the silence I’d heard so much of today…Vaarroooom!!!
