Hey guys!
So I recently did a fuel pump replacement and I got it all together and it appears to work because it made a sound. Okay cool.

The engine still won’t get fuel.

I checked the hoses starting from the fuel rail.
No gas.
I removed the fuel filter, and still
No gas comes from the hose from the tank.

I checked the fuse, I primed it, and still no gas with the key in the on position. I even tried cranking for a second to see if the fuel would shoot out. Still no gas.

I went back to recheck my installation, took out fuse, and as I took off the hose that’s supposed to come from the engine back into the tank, gas started to come out from the tank. I put the hose back on shortly after.
Then I decided l’d remove the gas cap and it started to release what seemed like a decent amount of pressure.
Continued to remove the other hose, that supposed to come from the tank to the fuel filter and it’s bone dry.

Is it possiable I installed the fuel pump wrong or the hoses backwards?

What should I check next.

Did the car run before you replaced it? Post a picture of the hoses on the fuel sending unit.

Hi James and welcome to the forum. I am not familiar with a fuel pump job but taking a look at the factory service manual would be a good start. You can find the pdf's here...

It did not run before replacing the fuel pump, but had trouble starting prior and then wouldn’t turn over the next day.

Here’s pictures of the sending unit and where the fuel came out.



And here is after I removed the fuel filter, and the hose where the gas it supposed to come out. Only a little comes out. Like a small syringe amount. And it’s only done it a few time. Other times it’s dry.

I'm not familiar with the fuel pump.

you might have switched the hoses. It's also possible that you reversed the wires.

What about the hose inside of the tank? Make sure it's still attached and the pump isn't just spraying fuel around inside of the tank. I doubt you swapped the hoses they kinda stay in the right spot on their own

JvG

I think Violator is correct.

What type of pump did you replace it with? Aftermarket or used OEM? As Violator said make sure the hose inside the tank is still attached.

It would also help to explain what you mean by replacing the fuel pump... the pump itself or the entire assembly?

Are you sure it's your fuel pump that's the problem? Check your ECM and see if that's burnt out. That's been the case fot me when my cars weren't getting fuel.

Before we even start talking about ecm, have the key turned to off for at least 5seconds and then turn it to on (not crank to start) and you should hear the fuel pump prime for a second. If this noise isn't there then your pump isn't getting power, blown fuse, not plugged in, or maybe NATs has you immobilized or something with a bad connector or bad fuel pump.

Ensure that the fuel pump fuse is:

(1) in place;

(2) properly seated;

(3) its contact tabs are clean and corrosion-free;

(4) the fuse itself isn’t compromised [i.e. burnt out]
