Jeez, what a rip. I hope you get everything resolved. I'll look in to the sender.

John How many miles on the expy If anything over 125000 I would suggest you replace the complete assembly

Also I don't believe that you can just replace the sending unit At least I wasn't able to locate just the sending unit for my 01 when it needed replaced

150K or so. Do you mean the entire fuel pump assy? I can do that. Might also take care of the very occasional stall when I come to a stop after a long drive. RPM will drop and either stall or "almost" stall. Starts right back up and runs fine. Not asking for advice, necessarily, just thinking out loud. Looking at NAPA, there are many choices for the Assy. I'll have to determine which is the correct one. I may run a tank with a fuel cleaner first.

Yes the entire fuel pump assy. Check you fuel pressure at the fuel rail also replace the fuel filter check pressure first get the figure, if low replace filter then recheck pressure But in any case replace filter if it hasn't been done

Stall could be due to many things DPFE sensor or the hoses to the sensor, MAF sensor, vacuum leaks and much more could be the cause

Some info for you

thanks, i'll look into the site. I live in a dusty environment, and I clean the MAF sensor with a spray. I replace the air filter also. I will let you know the outcome. I appreciate your input.
