I'm stuck on side of road waiting for AAA.

truck died doing about thirty, lost all power, everything lit up, and the only fault that registered was alternator fault but i'm not sure if that was bc of reduced voltage.

Recently i had service light come on and diagnosing found it was the ignition coil.

Im not sure how to find if it's the ignition coil or the alternator. now it turns over and over like it wont start. let me know asap guys!

Thanks!

Your symptoms sounds very much like crankshaft position sensor gone bad.

If you suspect ignition coil, I suppose you can check if you're getting spark on both A/B bank side. If your alternator was bad, you would have seen a gradual shutdown of all electroncs. Did you see that happen in your case?

Ahh, i was thinking maybe cps.


It was probably more sudden than an alternator going. Like where everything runs on battery briefly until it dies, right?

Depends on which year you have. On GEMS it is two 8mm and one electrical connector. I think that the size changed on Bosch.

socket wet will be just fine. It'll take longer to raise the truck to wading mode and crawl under than it will to change it. :mrgreen:

Standard tools are all you need on this one. The bolt is a bit on a small size. Don't remember exactly what it was though. Socket or std wrench is all you need.

You actually have 4 bolts. 2 bolts holding the cover in place, and another 2 holding the sensor in place. These two are not the same bolt sizes, If I remember correctly. Caveat is, you don't tighten down the bolts holding the sensor much-I believe, it's 6 lb/ft torque value.

BTW, I haven't tried them , but you can buy cps from local auto shops like Autozone. Naturally, they are not Bosch-made, but one I found was made by Wells. The price was bargain basement $59.
