Hi, I'm new to this site but i'm a fellow 240sx owner. Me and my guy just swapped a s13 sr20det into my 89 240sx fastback. I got my wire harness done with Heavy Throttle. We hooked everything up but the car doesn't start. My friend figured out that it's the fuel. My car is not receiving fuel to start up. I have about half a tank of gas in the car, so I do have fuel. I don't know what's wrong. The fuel pump is a new walbro one so I don't think that's the problem. All of a sudden my gas gauge says I don't have any gas. So I think it's something with the ecu or wiring. I just wanted to see what you guys think and if you can help me. I would appreciate it. Thanks.

 

Is your wire harness uncut or did you have it rewired??Sounds like a electrical problem....you do have to swap wires from the harness into the exsisting ka relays and fuse boxes for the fuel pump but if heavy throttle already did that for you then i dont know....i did my harness myself and follow the instructions from heavy throttles website and it works fine......check to see if you have 12volts going to the pump wiht the ignition on....check fuses and wireing(pinout diagram for ecu needed)....but it could be a bad ground or your ecu

If you like i have a disc here on the sr20det with full tech manuel on it(includes wiring,all mechanical etc)i can make you a copy and send it to you.....this helped me out a lot and was sent to me from a friend in japan....so its time to pay it forward...pm me if you want it...
