So I haven't had time to work on the truck for awhile, finally got time and got her started. New lift pump, new fuel filter, did the fuel heater/water in filter sensor delete, new lift pump fuel line and filter head to ip line. Had the fuel tank switch on the front tank which is full. Cracked an injector line and cranked for 30 seconds, let her rest for 2 minutes, cranked again, rest. No fuel to the filter, nothing coming from the lift pump. Thought great, didn't fix it. Then had a thought and switched to the rear tank which is 1/4 full. Cranked for maybe 15 seconds and she fired right up. Tightened the injector line and she's purring like a kitten. Switch to front tank and runs fine. Shut her off, let her sit for a few minutes, try and start and she won't start. Switch to rear tank, starts right up. So here's my question: why won't she start on the front tank but will run on the front tank? Bad selector valve? Or bad sending unit? Or neither?
94 F250, Bad sending unit, bad selector valve or something else?

What year and model of truck? It makes a difference and we will keep asking. So put this information in your signature by going to the top Black Line and clicking on your User Name and then click on Signature and fill out the details.
My selector valve died one day. Truck ran perfectly fine, got it home and it wouldn't run. It would fire right off quick then die almost immediately, wasn't air. Finally figured out it was my selector valve.
I'm wondering if you have crud in yours and maybe it's not fully switching when running or something maybe pulling from the rear tank the whole time? Don't know just a thought.
