My 1J won't fire. It'll crank all day long, but it won't spark. And yes, the plugs are new. Any possible suggestions? I've already confirmed it's not the ECU because I ran my other 1J on it. All the fuses are good too.:1zhelp:

Are you getting fuel? I know when I did my swap, I had the fuel wire power wire from the engine junction block mixed up. After I fixed it, it was good to go. See if you can hear the fuel pump priming.

I forgot to plug my fuel pump relay up. It would start, but it wouldn't stay running. Good luck.

This problem occured before I pulled my motor when it my motor was still in my 90. When I shut it down, it was running fine. Next time I went to start my car, the main fuse was blown. Replaced that, and now it won't fire.

check your codes, if it is a code 14, its either the ecu, the ignitor or the wiring between. You said it isnt the ecu (guessing you tested a known good one). break out the multimeter and check the wiring between. If that doesnt do it its the ignitor (140 from napa)

I am currently having the problem with crank but no start - and I know that I in the same situation were I have no power to the fuel pump. I have already started the engine by jumping FP directly to the battery. But I cannot start up normally. What wires did you have mixed up? Is there a site were I can find wiring diagram? for 1j. I have done a jump connector for body connectors based on the info given on 1jzgte-us
