22RE blowing EFI fuse repeatedly.

[DemonDave]

Okay, so on my way home from work yesterday my 93 Toyota died while running about 60 or so down the highway, wasn't getting fuel, assumed to be the pump. Turns out to be the EFI fuse blown, replaced fuse, ran great, backed out of the driveway and it blew the fuse as soon as it hit about 2k rpm in 1st gear. Next fuse bit the dust as soon as I switched the key on. And the following one once again at about 2k rpm in gear after no load rev to 3k and idling forward and backward around the yard. Can't find a visable bare or burned wire, or any bad connections at the harness plugs. Anybody know of a common issue or a good place to start on this one?

had one do that and the 02 sensor wire had melted to the ext. pipe causing a short.

Yea, look around the engine. kinda sounds like when you load the engine it torques over and causes the short.

also just remembered another toyota pickup that the speaker had come loose in the passenger side dash and rubbed a bare spot in a wire going into the ecm causing the efi fuse to blow. at random times.
