Ok, I've googled and have done alot of research and still cannot find anything close to my problem. I recently put in an s14 sr20det into my 91 s13. Everything went perfect until wiring, of course. I know everything works because i just pulled this motor out a hardbody, before driving it around for about a week. Ran perfect! now to my problem.


The person who did this swap completely raped the sr harness, so I used a spare KA harness and repaired it using the complete write up/ pinouts from the nicoclub forum and ecu pinout. I'm really not a mastermind at wiring, but i understand it. The motor cranks over but i am not getting fuel. The fuel pump would not prime so I hotwired it just to make sure it is good, however when i did that the motor would still just crank. When i turn the key to the on position all of the relays click, and the light on the ecu does not come on. I have checked all of my grounds. Also, the lights (check engine, seatbelt, ect.) stay on when the ignition is in the off position. So i know that a wire is crossed on that, and will fix it. I ran a check light on the wires spliced into the brown and gray plug by the battery tray, and everything was getting juice besides the fuel pump (black/pink to black/yellow), so i know that i need to trace it into the relay. My question is if the fuel pump is on when hotwired why wouldn't it start and just crank? I'm getting spark, injectors are good ect.
Also, why wouldn't I be getting power to the ecu? I know it couldn't be fried, or bad because i literally just pulled it and it ran perfect. Just looking for some suggestions. I'm baffled at this point.
