Question Won't start

TRUCK: '97 converted to e-fuel (SD Bosch).
MAINTENANCE: Replaced fuel filter & motor oil before summer travels.
TRIP: Traveled 5,000 hard miles pulling a 5th wheel RV.
1st SYMPTOMS: after 5k mi truck began to sputter while on d2 like it was starving for fuel. Began to get the occasional check engine light. Truck died while taking off from a stop sign.
MAINTENANCE: replaced fuel filter; truck started up after a few cranks & was able to drive it home. Replaced motor oil.
PROBLEM: Tried to start truck again... will now no longer start. The pump does appear to be supplying fuel at key on.
Thanks in advance.

Post on the proper year area for your truck and I will try and help. We need more info. What year truck? V3 or V4 system? Is it Veggiegarage Efuel? Do you have a fuel pressure gauge?

Thanks for the quick response Dave.
Would you like me to start a new thread in the OBS section, or can this thread be moved?
Truck is a 1997 (as stated in first post). V4, no fuel pressure gauge.

Will it start with V4 in manual mode?

How do you know it's getting fuel?

It doesn't seem to be getting enough electricity to turn now. Batteries are each showing enough volts on the meter...

I undid the fuel fitting in the valley, keyed the electrical pump on (didn't start it) & fuel sprayed out.

What is your idea of "enough"?

Was about to give up & take it to a mechanic. Checked the dip stick... too much oil!
Drained about a quart, truck started right up. *face palm*

Well, that doesn't make sense to me.... I don't see how an extra qrt of oil can cause a no-start.

As far as electric power goes, these trucks need to see 10.5 volts while cranking in order to start. I've seen plenty of times the engine spins over 'just fine' but won't start. A dead cell or 2 in the batteries is often the culprit.

Anyway, I'm glad you're running again.

Help me out but how does too much oil make it not run? My truck runs like crap 500 miles after an oil change so just wanted to see.

Question

The issue returned and there seems to be a new diagnosis: the PCM is not sending enough volts to properly operate the IPR.
Thoughts?
