Guide me in the right direction...

[tomsupra48]

Ok, Im new to working on anything diesel so here's the deal..
PS Ive done some searching and reading up already just need some direction...
97 powerstroke, 143k
all stock (original brakes)
cherry, cream puff truck.. (my fathers)

Quick backround, This truck is my fathers and is used for towing a race hauler, it was used regularly from 97 until about 08, then it barely got used up until 2 years ago I started using the truck on a regular basis. (several times a month)

So in the last 6 months or so the truck would start up, then 5 seconds later die, restart and it would be fine... only when cold. last few weeks it would do it maybe twice before it would clear out and run fine.. always ok if it was warm...

The other day I drove the truck all day, ran great no issues... About 11 PM I went outside to move the truck, waited for GPs, fired right up, ran for 7 seconds, died... cycled the key, waited to start again... fired right up for 3 seconds, died... then it was dead... it would just turn over and over with out any effort of firing...

next morning... I replaced both batteries, no fix (needed them anyway)
replaced the CPS, no fix
checked FP at the schrader valve... turn key to on, no FP.... turn the engine over it sorta pumped its way up to normal FP.... so it had FP...
I then checked the HPOP oil level... it was low... I added about half quart of oil...
waited to start... turned over engine... about 5-6 seconds worth of ignition the engine started...
I let it warm up, then I shut it off and cleaned the k&n filter and did some other things...


Question... Now when I go to start the truck it ALWAYS takes 5-6 seconds... it doesn't just fire like it always did...

any guidance is appreciated!

oil level in crankcase? Recheck oil level in hpop too.

Truck has mech. Fuel pump, so no pressure till cranking anyway.

Are you getting smoke when it's cranking?

If you plug the truck in will it start okay?

Test the glow plug relay.

Battery cables and clamps? Fuel filter?

recheck the hpop oil level. it's clear that it's already bleeding back. that needs to be fixed.
if it's low, you fill it, and it fires right up (or faster at least), that's likely the problem

I re-topped the HPOP and it starts perfect now. What caused the HPOP to get low in the first place, or what needs to be addressed?

check crankcase oil for proper level. If gud, and hpop STILL bleeding back, might be a stuck checkvalve..located d/s under hpop. Can get to it with 3/8in extention, but a pain, or could be a crack in standpipe in the hpop...that will suck.
