Attention: TDR Forum Junkies Hello all,
I've been digging through the forums for quite some time now (months) and am trying to hold on to hope that I am not in need of a new VP44.
My truck runs great!! Just mounted a fuel gauge on it and it's reading 12psi idle and 8-10 psi wot (pre filter, oops - I'll be switching the port this afternoon).
It starts like a champ cold.
When I lean on it for a spell and have the truck up to temp (again, it drives great). I get to my destination, park it..... go to start about 30 mins after it has been sitting, and poof - it will not ignite (like it has no fuel to it). It cranks and cranks.
**If I start it right after I park, it will usually start right back up - only when it sits for a bit will this happen.
I've gone through:
1. New batteries,
2. Alternator
3. Starter contacts (The Gould kit from Geno's)
4. Fuel filters
5. Fuel filter housing heater o-ring saga (yes it was leaking - thought that was the cure 4 months ago)
6. and now the FP gauge
Not sure what my next step could be. I really feel like I'm losing prime in the system when it sits, but can't trace this to anywhere.
I've now read Bluechip's diagnosis and see that the heat puts a licking on the IP computer and until now, didn't think this was a factor.
After about 2 hours of sitting and more stress on batteries/starter/truck than should ever be (as well as the please start dance outside of my truck in public) - she will fire up and run like a champ again!!
I know this is a similar post as so many out there in the TDR world, but I'm looking for the needle in the stack that will end this battle.
Any help would be greatly appreciated. I'm putting business on hold today and heading home now to get dirty on the rig once again - hope I can catch something I missed.
Thanks everyone here for all of the information and assistance you have posted. I'll keep mine up to date on the findings.
Thanks,
Erik
***more stuff:
1. Showing code P0380 - Intake Air Heater Relay 1 Control Circuit Malfunction
2. When bumping the starter (or cranking on it like I'm not supposed to), the fuel gauge gets to 12 PSI, then when the LP cuts off, the pressure drops - is this normal or is this the sign of a loss of prime?
3. **In desperation as I'm sitting in a parking lot with WIFI and dead in the water - I read BlueChips VP44 Diag once again and have poured cold water on the pump without any result - Following that, I angrily threw the empty bottle at the engine and this also resulted in nothing.
