4. Fuel inj. or eng. control systems malfunction.

My filter is kinda dirty, might as well try it I guess.


I can't find any vaccum hoses off or leaking anywhere.


I got new 255lph fuel pumps from PSP about a year ago so I would doubt it was though? maybe the fule regulator, but how often do those go bad? I have a spare adjustable one.

number 4, ***** thats allot to check.

Hey what's up Killa. Maybe the hose that goes to the fuel pump is ready to come off. A problem that i had. The factory used *****ty clamps. But I'm sure you used way better clamps when you installed the 255's. But you never know.

How about the Throtle position sensor. Check the voltage on it even though i dont think it could cause that probem.

Joe, how do you do all this so fast ???
Plugs, plugs, and more plugs, MAF's, ENTIRE UPPER OFF TRUCK ?
Man I wish I had a dry INSIDE spot to work on mine.
I feel for you brother, have you tried the gas filter and Checking the coils yet ???? Remeber thats what mine did, when you ever so lightly touched the peddle is where the original dead spot was
I hope you figure it out today, God knows what you'll take apart if you don't

It does sound like it's gas or spark related ?

symptons

RTKILLA, If it helps, I have ALLDATA at the shop and I can send you (via fax) the diag. chart for the sympton you are having. It would take forever to post it here. E-mail me if this would help and I will send it along. Jon
