01 7.3 pwr stroke , cranks, won't start need tips

2001 7.3 pwr stroke 149 k Calif truck Consisted maintennce 3500 mile oil changes , 12k fuel filter changes, constant air filters, diesel fuel system cleaners Only one fix CAM sensor at 30k
Ran fine yesterday- drove it parked it
Went out today to drive it cranks will not fire
I read alot about glow plug relays , checking fuel supply , oil level , misc other probs that might cause this

Where would be the best place to start, not much of a mechanic, but understand directions, I would rank myself as knowing enough to be dangerous with diesels

Thanks for the help

When you are cranking on the starter watch your oil pressure gauge .. Does it show oil pressure?? If not you may be dealing with a HPOP not working properly .. If it does come up you may want to change your CPS .. I had one that just died and would not fire at all and it had only been in the truck about 30,000 miles.. You can change out the cps yourself it is pretty easy .. Get the CPS with the letter B in it .. It is only about 30 bucks..

Ok the oil pressure gauge goes up just above the L , then when I stop cranking ,it goes up to the normal range then slowly descends, Now I forgot to mention I did notice something the wait to start light was on longer than normal before starting . It is California the weather has been averaging around the 50's and 60's so not too cold

STEP ONE

I had the same problem last week after installing the Quad Commander. Cranks and cranks, no fire.
After removing the commander wiring from the sensors with no luck, I just assumed it must be the CPS.
A quick check on these boards suggested trying new batteries.
One trip to Sears and it lit up just fine. Turns out the batts can be strong enough to turn the starter, yet too weak to activate the IDM or the BFD (whatever that chingadaris is).
If your batteries are a couple 2/3 yrs old, they could be your problem. Even if it's not your problem, you can't lose buying new batteries.
This is an easy fix, try it first.

Oh yeh, Happy New Year

The California emission will have 2 GPR's, 1 for each bank of 4 glow plugs. It should start with a bunch of cranking at your temps if it was just the glow plugs. Do you have oil in the hpop reservoir in the top front of the motor? It has a 1/4" pipe plug in top of it with a 1/4" square drive hole in it to be removed with a 1/4" drive ratchet. It should be within an inch or so from the top when you check it.

The batteries must have enough juice to not drop under about 11 volts as the starter is tunning or the computer will not work and it wont start. So new batteries or old put a charger on them till you find the trouble or all the cranking will draw them down on you. Alsso, how strong is your starter, is it spinnig fast enough?
