7.3L Strange starting problem.

Hey guys I was reading about other starting problems but couldn't find anything that was similar to mine. MY truck starts fine when the engine is cold, and starts fine when I plug it in on cold nights. The problem is when it is at operating temp, and I shut it down then go to start it back up a couple of minutes later or second later it turns over fast but takes a longer time to fire. instead of the normal like 2-3 seconds it may take like almost 5. The glow plug light usually isn't on very long (I assume because the engine is warm, but I don't know.) I just changed the fuel filter like 6000 miles ago and the oil was changed like 150 miles ago. I'm not sure how old the batteries are, but like I said it turns over fast. Any ideas? As always thanks in advance.

pull the wire connector off of the ICP sensor and see if it starts any better, if it does the sensor may be going out.

it's on the driver side head on the inside at the front to the right of the fuel filter, it ha 3 wires in the connector.also if there is any oil in the sensor or under the connector you should replace the sensor.

it tells the pcm what pressure the hpop is putting out. if it's going bad when you unhook it the pcm will defualt to a set pressure and even out if it's good you cant tell a differance in idle.

If you dont mind I'd like to pick your brain. So why do you think it would only have problems starting when warm and not cold?

I'm not real sure other than maybe the viscosity of the oil thins when warm. I had the same problem with my 2000 PSD and that stupid sensor was the culprit. it could also be the IPR but it's much more $$$$ than the ICP sensor. has the truck showed a cel light at all?

I'm not sure what you mean by a cel light. But it hasn't thrown any type of codes. Never mind I know what you mean by CEL. No it hasn't thrown any lights.
