Engine/Transmission (1998.5 - 2002) Long Crank at Initial Start Up Need Help

[DCraig]

I have a 2002 Six Speed. It is cranking for a long time before it starts at initial start up. After it starts it runs fine, and then will start quicly there after. You have to let it set for over two hours before it will do the long crank again. It has a new lift pump and high pressure pump and the lift pump is showing 18lbs of pressure. It is showing a snap on code of p0232. I need help and any suggestions. Thanks, sorry this is my first thread.

mine is doing the same thing. It acts like I just changes a fuel filter when it sits for say 20 minutes

I think there's a post within the last few days concerning this and I think it was the overflow valve on the vp44--sounded like it was an easy fix --you might want to do a search and see---if I run across it I'll link it for you guys---chris

I thought that the overflow valve coud be allowing the fuel pressure to bleed off returning fuel to the tank so I replaced it with a brand new one and it does the same thing.

Almost sounds like air is getting into the system during a longer sit period. Maybe fuel is draining BACK toward the tank. Any drips? Crawl under after a longer sit time and check all the fuel fittings to see if there are any drops of fuel outside the fittings.



Sit, sit, sit, crank, crank, crank, suck the fuel toward the VP, ignition. Sit, crank, fuel is at the VP, ignition.



Just an idea,

I have double and triple checked the fittings, I even replaced the rubber orings at the return fuel line t. Could it possible be inside of my new vp44?

If you have the factory fuel line from the fuel filter to VP check the small piece of rubber hose. There is a tag on the front side of the line. It wedged itself in the rubber hose and let air in the system. Might be something simple like that. Jeff

Just a thought. It may be that your fuel supply/return fuel canister is leaking. What we have seen is that the fuel supply line that comes out of the canister starts leaking. (sucks air and drains back) It happened on my truck also. It's the same canister that the fuel level sender is housed in. The cheapest way to fix it is to install a FASS pickup standpipe and change the fuel line slightly. If you need a VP44 we can help. Thanks 1-800-955-0476

Brett - What is a "The cheapest way to fix it is to install a FASS pickup standpipe"?



Is it a seperate standpipe pickup inside the fuel cannister? from the OEM one? or inplace of the OEM one?

I have taken a five gallon container of Fuel and placed two lines in it. One line is running to the lift pump and the other is running to the fuel return line. By doing this I should be able to determine whether the leak is in the lines or in the pump. I'll let you know what the test reveals and if I'm able to fix it.

Have you been able to fix your problem because i have an 02 with a similar problem on the long crank time
