Wow. I don't have another suggestion. It's a pretty straight forward circuit.

Let's go about this another way - what happened specifically?? You didn't say...

Were you driving and the car quit ???
Did you finish a repair/modification, and the car never came back to life ??

 

i put a mini battery on the car and a maf tranlater drove to the store real quick to put gas, i forgot to put the strap on the battery to hold it down so it moved and grounded out on the body of the car and i have checked every fuse, relay, circut and im starting to go crazy cuz everything is checking out ok, a few friends of mine think it might be the ecu. but i dont wanna go out and buy a new one and have it not fix the problem.

 

A little late. Thanks for the thread. Just had the same problem that I was trying to figure out for the last month. My issue was the MFI fuze, car was throwing both codes P0335 circut A. Turns out the fuze was loose. Car would start every once in a while would even turn off while driving. Then eventually it just wouldnt turn on anymore. Codes would not pop up until 3 weeks later. Then I read the info. So my fuze is loose. I turned on the vehicle and bam thing turns off if the fuze is touched. All other fuzes are stiff but not the MFI. So Ill have to switch out the box. My current fix is electrical grease I can shake the fuze around and itll still stay on. But thanks again for yalls imput.

Edit: relay not fuze
