long story short it has no spark and no fuel switched the efi relay with the def relay all fuses are good checked all of them one by one what could it be? Any input is highly appreciated.

 

might want to provide some more info like a sc400 or a sc300, things you have done to it, how many miles.
with what you have said first guess is fuel pump ecu has bit the dust.

 

I did the mod on the fuel pump control plug jumped the red and black wire with the green and that took care of the issue now it stars on point but the pump sounds different.

 

well its running at 12v all the time now. it will also run at key on engine off. may want to look into replacing the fuel pump ecu for it to be like stock again.

 

yeah i need to look in getting a fuel pump control.

 

What the heck what could this be, i get 12v at the green and red and black cables that go to the fuel pump control and i keep blowing the 30 efi fuse any suggestions?

 

maybe the alternator.. but obviously some kind of electrical issue somewhere.

 

Thanks Ali the an electrical issue for sure it was the fuel pump cover that has the 8 8mm bolts that hold it against the gas tank it was not in place so it wasn't getting enough ground put it back drained the gas because this car has been sitting for 10 years, put new gas back in there turn the key it started right up now I need a working fuel pump control!!!!
