will not start

[Johnny350]

Hi All,
I have a 2000 F-350 7.3 Powerstroke. I stopped by a friends house for about 15 min. I left the truck running and when I came outside it was dead. I tried to start it several differnet times, until batteries were dead. My brother brought me two fresh batteries and it still didn't crank. My brother did notice that no smoke was coming out of the exhaust while I was trying to start it. He suggested we check to make sure the oil resivoir (for the injection system) was full, it was not so we filled it up. It still won't crank and there is no smoke coming from the exhaust while trying to crank. My brother smelt the exhaust and said it smelt like oil. We have changed fuel filter and checked fuel pump.
Any help would be greatly apprieciated.

Sorry for the long post.

Probably needs a cam position sensor. Most 7.3 guys carry a spare, it is a common problem. Good luck.

also try checing ur oil level. if the oil level is low the superduty 7.3's will shut off and not start. if that doesnt work check while u crank it and see if the tach moves. if it stays on "0" while u r starting it, odds r ur cam position sensor is bad.

I appreciate the info. CHAD5.0. I will certainly give this a try as soon as it quits raining, and let you know how it goes.

Thanks Again

Thanks DirtyDiesel I'll go chech out the tach right now.

[Johnny350]

Checked the tach and it does move slightly, could it still be the CPS?

[DirtyDiesel]

its most likely not he cps if the tach moves. the tach runs off of the cps, so if the tach moves then the computer knows that the motor is turning. check and see if the fuel pump is runnig on the frame rail also.

Fuel pump is running

[Johnny350]

Could it be that the fuel pump is not putting up enough pressure. We took the cap off the fuel filter and took the fuel filter out then cut the key on, fuel did start to fill the filter cavity, but it didn't seem to be under alot of pressure.

that could very well be the case i cant remember how much you need to get it to start but i think its over 20psi
