I have a 1995 F-350 7.3 L turbo diesel. the truck will start after a while then sputter and shut off. the fuel filter light came on and i replaced it but it is still doing the samething. what are some common problems that may cause this. i need help quick so i can plow.

 

Glow plug relay , (2)Cam Position sensor, buy it from International instead of Ford. These are two of the most common. The CPS is located on the leftside , front of the block down by the water pump. Takes a 10mm wrench , s.kuteman

 

anything else it maybe. i have a diesel jetta nd the thing died on us because the fuel froze is that a posibility. how much do those parts run. I am thinking it is fuel related because when i changed the filter it started right up is that possible.

 

sounds like cps to me too

 

Does to me too

 

well i called a diesel mechanic and he said it is most likely the injector pump. it turns over and then cuts out. also when it turns over no exhaust is coming out and before it would be white if it did not start.

I'm fairly new to the PSD but here are some questions for ya...
Does the tach register when you're cranking? If not get a CPS (from IH for about 90 bucks) if it's bad the computer won't fire the injectors, as this sends info to the computer as to the crankshafts position. Have you checked fuse #22 under the hood, it's for the fuel heater and can cause a no start problem. Just my .02 worth.

well when i spray alittle ether in there (not enough to damage anything) it turns over like it is going to start. i understand it might be the CPS. how do i get the sensor for $90. i also called a ford edealer at this point and they said they replace alot of the injecotr pressure seliond i think it is called. do you get a cheeck engine light when this sensor goes bad.

 

A 95 7.3 diesel..........Doesn't HAVE an......Injector pump.....The whole system was changed at the end of the 94 model year!!.......s.kuteman

 

when its running dose it run fine or dose it just sputter

 

because if it just sputters and barley run u might have jelled fuel

 

the 7.3L turbo diesel has and injector pump or at least ford has one listed. if it does not have an injector pump then what moves the fuel. when it runs it runs fine then spudders and dies. also i pulled the new fuel filter out and the fuel was fine

 

Ford got rid of the Injector pump and the 8 individual tubes to carry fuel to each piston. They Cast the Pathways for the fuel into the heads. The fuel is injected by utilizing a gear driven pump which uses the engine oil as an energy source to move the fuel to each individual injector which is time sequenced by the engine computer. That is why the Cam Position Sensor is so Important becasue it keeps the Computer constantly informed as to the exact position of the cam shaft and crankshaft. An injector pump is tied directly to the camshaft so it doesn't have to worry about anything else. ............s.kuteman

 

well somebody is confused then...i am going to try to take it someplace tomorrow i need it for plwoing on wedsnday this sux you guys dont know. how hard is it to change that sensor

 

the dealer said that it could be the injector pressure relay......where can i get the CPS for 90
