Im haveing problem's, please help.
 

HI.I did a t2 s4 swap in a 87 base model rx7,like a monthe ago and my fuel pump went bad. But when i did my swap i used the n/a resistor and ran my car on the n/a fuel pump,and yesterday. I put on a t2 fuel pump and my car started right away lift it on for like 20min and reved it to like 4,000 rpm and it stalled,and now my car wont start. What can it be.Thank's for the help. :banghead:

So nobdy know's...

It could be many things.

Check for fuel at the rail
Check for spark
Check for compression

Do those things, and come back with the results.

+1....

Check for full current to the pump, then check to make sure fuel fets to the filter, then check to make sure it goes PAST the filter and into the rails.....

Could be the pump, filter(s), injectors, vaccuum leak.....

You should go test everything you THINK could be wrong and when you're STUMPED and cannot think of a single thing...come back and ask....

right now you have no info for us so we can't give you any conclusive responses other than: find out.

Make sure all your hoses are connected.

make sure the relay on the driver side firewall behind the trailing coil, isnt bad it will not let the fuel pump kick on if its bad ran into this problem today with 88 vert/na
