Another no start problem

97 Powerstroke, Manual Tranny, 176K

Facts:
- wait to start light comes on
- scanner communicates with PCM
- duty cycle test for injectors shows over 500 - closer to 1000
- replaced CPS
- #22 fuse is good
- new oil and filter
- new fuel filter
- topped off oil in HPOP

Truck tries turns over and cranks but will not start. Ran 4 weeks ago but then nothing. Only problems leading up to this was occasional rough/shaking at idle but would smooth out once under load.

I have a used IPR on the way to try. Can the glow plug relay go back and the wait to start light still come on? Anything else basic before I tear further into it and throw parts at it? This i my first diesel and Im new to how they work

Re: Another no start problem

I'm assuming if the scanner communicates with the PCM, you've checked for codes? Is the CEL illuminated? Getting a bunch of white smoke out the tailpipe when trying to start? Does the HPOP reservoir empty after cranking? Glowplug relay and the WTS light really have nothing to do with one another (so, yes the relay can be bad and the WTS light will light). Cheers!

Re: Another no start problem

Ill have to take another look at what codes were showing, its been a month ago since I had it scanned. No the CEL does not stay on but it does illuminate when first turning the key over. No white smoke when starting. The HPOP res was emptied when the no start problem began, I refilled it after changing the oil but I have not checked again since. Will do and report back. Is there an easy way to check if glow plug relay is bad? Could the engine be started if it was bad?

Re: Another no start problem

If it was just the GPR, you would be getting white smoke out the tailpipe. The truck may or may not start with a bad GPR depending on conditions at the time. To check the GPR put the DVOM leads on both large posts (one on one post the other lead on the other post. When the key is in the wait-to-start position, you will be measuring the voltage drop across the relay. Anything more than 0.3 volt on the meter (the voltage drop) and the relay is bad. Cheers!

Re: Another no start problem

Truck has sat for 3 days since i last messed with it. After cranking for a 20 seconds or so I removed the plug in the HPOP reservoir and it was dry. Does this mean the LPOP is bad? I filled the res and tried again but nothing although the res stayed full. Where is the LPOP on these trucks, is it in the pan?

Also, no white smoke during cranking at all and the tach does move. Not getting any oil pressure reading after 15 sec of cranking.
