Swap help! No Fuel!

[GTR-33]

I got my redtop in my S13 all hooked up, and I'm getting no fuel pump action... The SR cranks and everything but no fuel. I sent my harness to HT to have it 'modified' but it doesn't look like they did anything to it to me. Just charge me 100 bucks and sent it back. My guages light up, but don't seem to be working either, I have gas, but it says the tank is empty.

Did you check the fuses and relays?

Is it an aftermarket pump? Are you sure it's wired up right?

Check all the connections between the pump, relay, and fuse for continuity. Try applying power directly to the pump, make sure everything is ok individually. My friend had a problem with his car that sounds similar to yours. His engine would crank, but the fuel pump wouldn't go on.

here's a thread that details everything he did and went through to fix his problem.

BE CAREFUL AND CHECK YOUR ECU!!!! My friend's problem was his MAFS wire was shorting out the ECU...he fried his PowerFC and stock ECU. He had them repaired, but they may never be the same.

I had this problem too. Did you check to see if the fuel lines are reversed. My fuel lines were reversed and once I swapped them the motor fired right up. So check that first.
