fuel pump!

well im pretty new here.. and yeah i just got a rx-7 2nd gen(1986) from my friend and yeah it doesnt start i did most of the common diagnostics

I already checked:
fuel
spark plugs
oil
battery
fuses


but it seems that i took out the incoming fuel line that goes into the block
and see if gas pours into it.. and it doesnt..so im wondering what would be the problem

i already bought a universal fuel pump..
but it seems that doesnt power up from the line going to the old pump

i spliced the required wires and re-attached them to the unversal fuel pump

so can you guys help me out.. i would love to drive my rx-7 around!

on the driver side's side there is a yellow two prong connector coming off the engine harness, near the strut tower. jumper the two terminals together with the car off and the key in the on position, that's your fuel pump check connector. you should hear the pump running if it works and obviously fuel will be flowing through the feed line.

and you should have replaced it with a used stock fuel pump. You could get one right now used for like $30 or something and it will fit right in without any bullshit. nonturbo rx-7s, unless heavily modded, are fine with the stock pump.

you need to read the factory service manual in the FAQ. fuel pump is located under the rear carpet, beneath a panel towards the driver's side. There are wires going to it. You can remove it with a simple screwdriver.

But if you have not pulled out your stock pump yet, you need to use that check connector I mentioned. If you hear the pump running it should be fine and you have another problem.

Did you jumper the fuel test connector? That would be a cheaper fix then that silly universal FP you just bought.
