hey guys... i have a 1992 240sx coupe with a red top sr swap into her.. the swap has been done for quit a wile now and has been daily driven and daily abused very hard and has held up awesomely. but recently iv had some gaaaaay probs with her, first the fuel pump stopped working (walburo 255l) so it wasnt such a big deal i just ordered one and installed it. then i went to start and the fuel pump wont kick on the engine just turnes over not starting.. so i contacted yuri at the wiring specialties who did my harness and he gave me a few idias.. well first i checked for spark by taking a coil pack out and grounding a spark plug wile a buddy turned it over.. NOTHING! no spark.. so he said it might be the ecu well i tired a friends stock 62 ucu and that didnt work either.. so idk if any of you guys have had this prob before but i can really use some guidence. cuz the car ran just fine for about 9 months then quit. theres simple bolt ons but nothing too drastic that would cause major wiring probs i still have stock maf and no fuel controllers or anything wired in at all so yea ANY help at all would be highly appreciated... thx alot:wtc:

Is your fuel pump still not working?

i had a similar problem look at the wire harness around the #4 fuel injector the big clump, I had a problem that my wire harness got rubbed through and grounded on the injector rail, so pull the harness from back in that area and look for exsposed wires.
