I blew 3 EFI Fuses today - Toyota Nation Forum : Toyota Car and Truck Forums

My car died after 5 seconds of starting today...after some trouble shooting it was a blown fuse...

The only thing I can think of that would cause the blown EFI fuse is a home made fuel cut switch aaron and i installed a few weeks ago (which is what I first inspected) all the connections seemed fine, nothing was grounded.

So i drive the car home then back to school with no problems.

Then after 2 hours of class i go back to my car, start, dies. Replace it with another 15v fuse, then dies again. Then I put a 20v in, gets me home. I trouble shoot further at home, cant find any problems. I put another 15 back in, started it up 3 times and now no problem.

What the heck is wrong? Im guessing my fuel pump is sending a spike?

What should I do?

Problem seems to be solved...I stumbled on the source of the problem today, a pinched wire that was out of sight from the fuel cut assembly...Its all fixed now, thanks for the help
