97 7.3 Problems

Last night my (new to me) truck started acting up:
- 1st, it had been doing this thing recently where shortly after starting the pitch of the engine got pretty deep for probably 2-3 seconds and then it would return to normal sound.
- It took several cranks before finally starting. This morning when I tried to start, it took even longer and started to self rev when it stared (almost sounded like it was to keep it from cutting back off)
- It started idling and running rough
- When you turn it off there is a weird sound coming from the fuel tanks, almost like a gurgle or sloshing sound (I didnt even drive it anywhere when it made this sound)

We have had our first colder weather here in TN and I dont know if that may have something to do with it (it was low 50s last night)

Any help would or suggestions would be greatly appreciated. I hate to see my 2 month old truck with only 113k miles already giving me problems, after I had it checked out and everyone told me how good these things are...

oh, and before anyone asks, it does have a half tank of diesel and I have been letting the glow plugs warm up...

only suggestion i have is in regards to the long/several cranks before starting, your Glow Plugs are probably wearing out. good chance their not heating cylinders enough.

if you see a light at the end of the tunnel, it's probably just a photon torpedo

Yeah I agree, it could also be your glow plug relay.

had my buddy come take a look. It kept pulling the code for the cam sensor, we changed a wiring harness on that and the sensor with the same problem. We then looked at the fuel pressure and fuel system and realized that though the gauge read 1/4 tank, it was bone dry....needless to say, added some diesel and was good to go.

I did find out that I have two glow plugs that are shorted out so were going to get those changed out along with the gaskets and wiring harnesses. when we do that im going to go ahead and change the fuel filter and flush out the radiator and start with new antifreeze for the coming winter.
