7.3 starting problems

I have 97 ford f350 powerstroke it has 90,000 miles on it. It's is the truck in my avatar. I don't drive it often only sometimes on nice days. It is always garage kept. I tried to crank it last night and it sounded really rough like it was loping. I backed it up but it wouldn't take any pedal. All of a sudden it sounded like it was running out of gas but it had plenty of gas. Now when I try to crank it, it acts like it wants to fire but it seems like it seems like its no getting any fuel. Last time I drove it everything was fine. Never had any problems with it. Obviously seems like a fuel pump problem, or a fuse or something. What do u guys think it is?

Check fuses. I forget which one but one of them goes when the fuel heater goes bad. Then it wont run. If all of the fuses are good and the oil is full check for fuel flow by loosening the fuel filter cap and cranking. If you have good fuel flow it is most likely the CPS.

I could be wrong here, but it sounds like the cps is shot if your giving it throttle but the truck isn't responding to it.

Replaces the CPS still wouldnt crank. I drained the water fuel separator. Tried to crank it again and check the fuel bowl it had fuel. I'm thinking about replacing the fuel filter anyway.What else could it be?

definitely sounds like a fuel delivery issue to me. have you checked the fuel filter? try switching tanks. are you getting sufficient fuel pressure at the bowl?

Just wondering if we jumped right past glow plugs? It just started snowing here? Maybe plug in the block heater.
