Hard starting with new glow plugs!

[1ofakinddrywall]

I have a 2004 6.0 and have 185,800 miles on her. And yes at 178k i had my egr blow, had to replace and also redid head gaskets. They replaced all glow plugs. Truck use to start under 4 seconds, now i can crank it for about a minute and nothing, if i kep playing with it it will finaly start. no smoke when cranking or oders. Could it be a fuel pump?

High pressure oil leak somewhere?

[1ofakinddrywall]

I dont see anything leaking, motor is dry and no spots in driveway

[thorx4md]

High pressure oil leak would be internal. You wouldn't see any oil on the ground or on the motor.

[chuckles]

yeah, high pressure oil leak. Did this problem occur right after the head gaskets were done?

[thorx4md]

Did you do the HPOP STC while you had it apart?

[1ofakinddrywall]

No i had head gaskets done a little over a month ago. When i got it back from dealer it took a few extra rotations before kicking over but not as bad as it is now. Its like russian rullet, sometimes she starts right away some times Im imbarised in front of coffee shop when she wont start for a few minutes

[1ofakinddrywall]

Dont know what HPOP STC is.

[chuckles]

you need to check build date. I only the STC fitting was on 05 and up trucks.. STC fitting is "snap to connect" fitting. It's a quick connect fitting that connects the high pressure oil pump to the branch tubes for the high pressure oil system. It fails with utmost certainty on 05 and up trucks, especially soon after head gasket jobs, and causes hot-soak no-start conditions and usually gets worse. Do you have access to scan tool?

The easiest way to be sure is to check your ICP (psi) on a scanner while cranking. It should hit 450-500 psi within a few seconds if the system has no leaks.
