Trouble with an 'ol PSD

I recall reading something somewhere, maybe in my owner's manual that there is a fuel pump shutoff that is supposed to activate in case of a collision to stop flow of fuel that might cause a fire. I wonder if if simply kills the ignition circuit (which would shut off the radio and A/C)? There's some procedure to reset it if it happens accidentally, but I don't recall what it is. I would imagine diesels have a similar safety feature and maybe this is causing your problems?

It might be worthwhile to investigate this possibility.

Sorry but, that ole girl has a mechanical fuel pump, no inertia switch to be found.

Good thought though.

Hmmm, so what is a basic method of replacing that sensor? Also what is a good place to buy a replacement?

All you need to do is pull the 10mm bolt holding it in, and with a long screwdriver GENTLY pry it out. If is seems stuck try slowly twisting it to break it loose. Lube the o-ring on the new sensor with some grease or motor oil, them pop it in and you are all set.

You can find those sensors on e-bay for around $25. Get the sensor that is black or the one that is very dark purple. Gray and blue sensors are bad, but will work ok if all else fails.


Good Luck

P.S Did you get a code out of it?

[Longshot270]

Ok, I'll pass that info on to him. Thanks

No info on the code yet, not sure what is holding that up.

Colby, Colby, Colby.... u didn't even call me about this... i'm disappointed.

Come see me when your back in Drippin. i have 2 spare sensors in my glove box so bring me $15-20 bux and one is yours.

Dave, i have 2 of the IH sensors your talking about (the dark grey with purplish o-ring) that he can put in there. should fix that up pretty good.

Colby, i have a scan guage. if you want i may be able to hook it up b/c i have not mounted the guage pod for it in my truck yet.

Haha, you were at the top of the list but I didn't have your number. I was wondering when you'd find this, I'm disappointed it took you this long.
I'll probably be visiting this week some time and I'll let him know. Right now I can't figure out what he wants to do. So I take it that there is only one sensor?

yeah the CPS(cam position sensor) is on the front of the engine about the 10 o clock position by the balancer.

Ok, sounds easy enough. I'll see if he's gotten a sensor and scanner by now in a few days.
