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.
