S14 Sr20det NO fuel - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hey guys, got a quick question.

I just finished hooking up and swapping my s14 sr20det into my s13.

I got spark and the starter cranks over but Im not getting any fuel and the pump is not priming. On top of that, after I turn off the ignition and even pull out the key, the cluster warning lights are still on.

Any ideas as to what is wrong?
Ground, ecu or something else? Pump should be good as the car was running fine before the engine swap.

Did you wire it correctly? Sounds like a power wire somewhere is hooked up incorrectly. Start from the main fuse box in engine bay and start looking around. Did you do the sr wiring harness or did someone else?

Wiring harness is brand new from wiring specialties, and yes I ordered the correct one.
Everything except maf and 02 sensor are hooked up, and those two should not affect the fuel pump right?

Naw, the fuel pump circuit doesn't care. Find the fuel pump relay and jump it and see if the fuel pump comes on. Only problem with that is, it doesn't fix the dash light problem. It still sounds to me like something is getting power that shouldn't be. I wonder if the ignition switch is shorted...

The Fuel pump relay is turned on by the EGI relay, The EGI relay is grounded by pin 48 of the ECU. If the EGI elay is clicking then check the fuse for the fuel pump. p.s. The ecu pin that controls those relays are known to go bad.
