Won't start unless plugged in

[Trey7.3]

Let me start off with all the parts I've changed already.

New GPs and GPR. Just changed hpop reservoir gasket cause it was leaking. New cps.

Truck will not start unless it is plugged in. It can be 75 degrees out and still wont crank. Although there was one week where it fired right up and it was about 40 degrees all week. Thought I fixed the problem but it still won't start unless plugged in. It's not throwing any codes. Just my water in fuel light is on.

Any suggestions?????

I cranked the truck this morning after being plugged in all night. Only took about 3 secs to start. Now every couple minutes it idles at like 1100 rpm's and wont stop until I hit the brake. Is this normal to make truck warm up? It never did it before.

Also how do I check HPOP pressure? Through the ICP? What do I need to check it?

Check the rest by the fuel filter it runs the glow plugs. Had same problem changed out and stars up just fine.

Yes on high rpm when cold not sure if that is a little high . Hoop should be mire than 3000 psi

Check what by the fuel filter?

I changed the relay already. The gps are working. I think it's the icp sensor. The connector is wet with oil when I unplug it.

I replaced my ICP and the plug, not sure if it did anything. The relay was for the glow plugs.

anyone tell me a good price for changing all 8 GPs with the berus? I would do the swap myself but this is the family vehicle and I am so sick of doing simple stuff and running into problems or missing tools or dropping that 1 bolt. And I can't afford the headache of not getting it done quickly and efficiently by a pro.

replace the fuel filter. has it been changed recently? I replace mine every other oil change (still have starting issues.....), but if you have water in fuel light, and it is old, I would change it out. also, there is a fuel filter drain valve that will drain out water from the fuel bowl. its yellow, and right behind the fuel filter. otherwise, good luck, im still trying to get my truck to start.....
