Are you sure the wiring is good?
Make sure your KA plugs (By the relay box) make sure the wires actualy match (Example: Black/Pink matches the black/pink)your fuel pump wire

I know it sounds dumb, But make sure your ECU harness is actually tight on the ECU.

The SR harness was from the same car the sr20det came out of. checked the ECU plug it is as tight as i can get it with a socket wrench. The kid i got the car from just put a new Walbro 255 fuel pump in so not sure what to check next.

Make sure both sides of the plug match up. I've seen different year S13's have wires in different locations.
IE. The plug on your engine harness side (make sure these wires match up to the chassis harness)

I rewired those plugs myself and checked them 4 times now.. think i tracked it back to the fuel pump not being good. I found a Nissan truble shooting gide seems to be good to pump. cross fingers he did this wrong as well and i can get it running.

unless u get a really really good deal its best to start with a unmolested harness from the sr20 and unmolested harness from the car. there are way to many variables. :bash:
