Starter/Starter Relay

[TSIMonsteR]

I searched, and found many threads and tried many things from those threads, but no luck.

Car won't turn over suddenly. Its been fine. I came home for lunch day, went in for like 15 minutes or so, came back out and the car won't start/turnover at all.

I checked and re-tightened the battery terminals. No luck.

DSMLink reports 12v coming from the battery and everything seems to work fine electronic wise, but I tried to jump it off anyway, but it won't turn over at all.

I tested all the fuses, none were blown, and I went ahead and replaced any fuses that I though could be hindering the problem. (even though the tested good via the Multi-Meter)

I assume it has something to do with the starter relays. I figure, if it was the starter, it wouldn't be such a sudden change. I would have had symptoms leading up to a starter failure.

As far as I know there are really only 2 relays that could be the culprits. The starter relay behind the radio, or the one above the driver side fuse box.

When I turn the key, the one behind the radio clicks, should it? I tried removing the theft/starter relay (the one above the interior fuse box) but it didn't change anything.

What should I look for/try next?

Not true, have had plenty of starters just die suddenly. I know it won't be fun but try jumping the starter. Oh is this a manual transmission, just thought about the clutch safety switch going bad.

Starter selonoid(eek don't have spell check on this cpu) is my guess.

It has been a while since I messed with a starter relay but if memory serves me correct yes the relay should click when you go to start the car which leads me to believe it is not the relay. Another way to confirm this is to look at the relay and see if it is a NC or NO relay.( I think it is a NO relay and it closes the circuit when you go to start the car allowing the starter to get power)

Take a test light and put it on the small wire on the starter. Have someone go to start the car. If it gets power then the relay is doing its job. Hope I am not too confusing as some days my brain works faster than my typing hands.

Good idea. That can be bypassed by simply unplugging the switch.

Its an Auto. Not to be a noob, but how would I jump the starter? Send power straight to the solenoid?

I'll go give it a try, but I'll have to wait until someone is home to help out.

To check continuity on the starter relay. Two diagrams.

Diagnostic procedure One diagram.

I've been having an intermittent start problem too that I'm trying to track down in the wiring. Follow the wire coming off the starter solenoid, it should be a single wire that has a harness that clips into the main harness. Unplug it, and jump 12v power to that single wire coming off the starter. If it cranks, you know it's not the solenoid, and a problem within the electrical path from ignition switch to solenoid.

Is this relay the same on 420a's?
I think it might be my problem.

On that relay what should the volt meter read?
Should I be checking volts or ohms?

I already have the neutral safety switch unplugged.
