Welcome! My name is ***** ***** I will do my best to assist you with this problem.Ask me about added features such as phone contact anytime if you wish !
I am sorry for the long wait
how long did the 2nd pump last for ?
when cranking it over the fuel pump will not run at all ?
do you have a multi meter on hand ?
Customer: replied 1 year ago.
The first pump I put in lasted about eight months. The second pump lasted about three months. I never let the gas tank get below a quarter. And yes I have a multimeter.

The fuel pump does not come on when I turn on the key
Customer: replied 1 year ago.
It does crank though
Expert:  Gary replied 1 year ago.
if you check the ground near the top of the frame near the filler neck is that ground clean and tight ?
if so then unplug the 4 terminal tank connector and meter set to DC volts red meter lead to the grey wire terminal in the connector you unplugged and black meter lead to the black wire terminal in the connector when cranking it over what will it show for volts when cranking it over ?

Do you mean take off the bed and check the fuel pump directly?

Hello?
Expert:  Gary replied 1 year ago.
you need to give me a minute to type back to you
yes that connector that plugs into the top of the fuel tank/fuel pump
usually you can reach up to unplug it or just lower the tank down enough to get to it to unplug and test the connector

11.72
Customer: replied 1 year ago.
That's right when I crank it then it dies out slowly
Expert:  Gary replied 1 year ago.
ok so you have a solid 11.72 testing where i said even when its not starting up when cranking it over ?
what brand pumps did you use ?
did you replace the whole fuel tank assembly or just the fuel pumps ?
Customer: replied 1 year ago.
The first pump I bought was from a cheap place. The second pump I bought was an AC Delco. Both times or replace the entire pump assembly
Customer: replied 1 year ago.
Both times I replaced the entire assembly
Customer: replied 1 year ago.
And yes solid voltage
Expert:  Gary replied 1 year ago.
with that good voltage when cranking it over that pump would have had to fail again
usually we see excessive water or alcohol content in the fuel tank cause these kind of problems and causing new pumps to go bad this quick
when the tank was down was it cleaned out dry ?
Customer: replied 1 year ago.
I didn't dry it out but it looks clean
Expert:  Gary replied 1 year ago.
with those good volt readings at the tank and if the inside is clean and all new fuel the pump was just defective
it should be covered under warranty
bring it back and get a new one and put it in
there is nothing else it can be with those test results to cause this issue
Customer: replied 1 year ago.
So now IOU $38? I pretty much thought the same thing.
Customer: replied 1 year ago.
