I would think you have a hot wire touching bare metal. Also installing aftermarket stereo's or other components could be the problem. Always check the fuse box for correct fuse amps

88 toyota pick up v6 keeps blowing efi fuse


you may have a short of some kind, when a fuse blows repeatedly it is no good just replacing, you are being told that something is wrong with the equipment.
You will almost certainly have to visit a technician for a diagnosis. It is unlikely to be something that an inexperienced end user can sort out I am afraid.

GOOD LUCK

The fuel pump relay is the EFI relay in trhe fuse box under the hood right fender. I replaced it and the pump is working I can smell the gas. The truck still will not start. any sugestions?


Have you checked to see if it has spark at the spark plugs, let me know. Actually there are two relays for the fuel pump, the EFI relay and the circuit opening relay, the circuit opening relay gets voltage from the EFI relay. If the computer doesn't get a spark confirmation signal while cranking then the injectors are shut off.

Cant find fuse for fuel pump


on the 91 theres a fuse box under the hood on the passenger side. In there is a fuse that is labeled EFI. Theres also a relay for the fuel pump there, its a round metal item. In truck cab on driver side near left foot is fuse box, EFI fuse in there also. This on a 4runner so you may be dfferent.

EFI Short


If you didn't mess with the wiring (cause some people do) you have a short to ground somewhere. basically you have to follow the power flow until you lose power and the short is going to be between the last spot you tested that had power (battery voltage) and the spot were you lost power. hope this helps
