Truck cuts off Help Please

[96Ford7.3]

Hi I have a 96 powerstroke that has run great ever since I got it and now I start it. It runs for 20 sec to a minute then cuts off. It will do it everytime you start the truck. I need it fixed my monday. Iv changed fuel filter, and switched tanks and it doesnt help

Those are the classic symptoms of a bad cam sensor. Replace it and see what happens. You should actually buy 2 and keep one in the glovebox. Seems like they never fail if you have a spare with you

I'll second that.....They did have a recall of sorts a while back, you might be able to get the dealer to do it for free, it's just a phone call, but as it's the weekend, you might need to do it your self due to time constraints. 5 minutes and a 10mm socket to find out if thats it or not.

ive actually had a work truck due this and it ended up bein very low on oil, but the cam sensor seems more right, just throwin my .02

Seen the low oil problem too, but it would idle great , just fell on it's face under a load.

The cam sensor recall wasnt included in the 96 7.3s but for 20 bucks it cant hurt to replace it. Mine did the same thing and ended up being a clogged IPR. they are about 120 bucks through Pensacola Diesel. You should also put a Scan Tool that will Data stream to really narrow down what you are looking for. It will show if your Cam sensor is working or not before you start throwing money at this truck.

I agree with getting it scanned.Think autozone checks codes for free.good luck bud.hope ya find what it is

[deezelfromRofo]

I think autozone will check for codes for free. Sounds like a bad CPS to me. But it is better to scan it than throw parts at it. Good luck Bud

Low on oil will do it, but you must be very low, The cam sensor is like a spark plug, always have an extra.

Checking the codes will help but you really need a data stream to show what your RPM,IPR duty cycle, and ICP pressures a reading to get an acurate idea of what your engine is doing. The down side is that autozone rarely has a computer that will data stream. But its worth a look. The RPM needs a clear signal over 200 and ICP pressure needs to be over 500 PSI. IPR duty cycle should be about 55% when starting then drop to 15% once running. Are you getting any smoke when cranking the engine over. Do you have oil pressure in the oil reservoir?

things you need to look at when diagnosing a NO Start condioion.
