I just took off my AEM EMS and put my stock ecu on. The car was running really bad with my turbo setup so i took everything off to put back to stock so i can sell the car. now with the stock ecu back in the car will not start. It turn over and cranks, but no spark. I check my battery and it fine and got a charger up to it.

I check the fuses and the ecu and pgm f1 main relay fuse does not have any power. The fuse is fine, but no power going to the fuse? Any suggestions. The ecu seem to click on the fuel pump and everything when you plug it in. Not sure if this help, but any advice is needed.

Thanks,

Jon To

Is the green key symbol staying lit on the dash?

Check your spark plugs.

Not long after I bought my S I had issues with the car starting after it sat around for a few hours, and after a lot of hypothesizing and experimenting with the battery, fuel pump, and starter motor, finally someone said to just check the plugs. Sure enough, mine were burnt (they were probably 8 years old). I replaced them myself and now the car ALWAYS starts right up, be it 115 *F or 0*F.
