I realize this topic is pretty well covered but I have literally spent all day today reviewing the postings, running to the truck, trying the diagnostic/remedy - all to no avail.
Son picked truck up from shop where they did $2K worth of work on ball joints, inner seals, etc. Truck died on the way home - Check Engine Light came on, battery light came on, etc. Truck progressively lost power until he got it off the road and safely parked.
Wife had the truck towed home.
Now that the truck is home the check engine light is off and there are no codes.
After spending $2K I've got to dive into it myself.
What it's symptoms are:
Cranks but won't start.
I get some RPMs while cranking, but not many (maybe a couple hundred) on the tach.
Checked all fuses under the dash - all good.
Can't tell about the dash lights, etc. since it's daytime. Will check tonight.
Wait to Start light comes on when turn key on - goes out after a while like usual.
What I've done:
Replaced the CPS (easy & cheap) - still won't start.
Replaced the fuel filter - fuel filter is chock full of fuel. Still won't start.
Checked the oil level in the HPOP - measured out at 3/4" from top of reservoir. This was replaced about 15,000 miles ago. Still won't start.
Checked the fuel pump - laid under the truck as my wife turned the key on - heard the pump engage. Sounds like it is working. Still won't start.
Checked conditions of batteries - seem to be charged. Cranks but still won't start.
Disconnected the ICP sensor (on the driver's side head behind the alternator) - check engine light came on. Truck cranks but still won't start.
What I've concluded:
This is like finding a needle in a haystack
The glow plugs are OK since the Wait to Start light comes on.
The fuel pump must be OK since the fuel filter is completely full.
The HPOP must be OK since a) My oil level is fill and b) the HPOP reservoir seems to check out (3/4" from top).
What I suspect:
Something may be going on with the injectors??? Could it be the IPR or IDM?
I very well could be wrong about the glow plugs.
I very well could be wrong about the fuel pump (seems strange that the fuel filter would be full - after checking multiple time - though).
I need help (I don't suspect this - I kinow this)
Any ideas would be greatly appreciated. I simply cannot bring it back to the shop. First, I'd have to have it towed. Secondly, I can't afford it. And lastly, it's now personal.
Thanks in advance for any advise/suggestions. I don't know the first thing about checking out the IPR or IDM, if that is even where I should be looking.
