Question about 1991 Toyota 4Runner

Will Not Start

1991 Toyota 4Runner V6.
Will start and run by shooting a little starting fluid in the intake plenum, but will die as soon as the fluid is gone. It keeps blowing the EFI fuse under the hood, so I tried jumping it, but it made no difference. Replaced the fuel pump, and still no change. There is no coolant or muck in the oil. All other fuses inside and under the hood are good. I was thinking of replacing the fuel filter next, but that still doesn't explain the EFI fuse blowing. Anyone have any ideas?

    I did already replace the fuel pump. I have not yet replaced the fuel filter. It seems as though fuel isn't getting to the injectors at all. Even jumping the fuse with a piece of wire it gets no fuel to the injectors. I do have a volt/ohm meter. Any further ideas will be appreciated.

    may have a shorted injector, try removing the injector connectors and see if the fuse blows if not then put the connectors on one at a time until it blows the fuse, if you have a volt ohm meter I can tell you how to test the injectors, did you already replace the fuel sock? and do change the fuel filter it will save you from buying a pump. The ethanol in gas ruins filters and injectors.

It will not run without that fuse intact. There is a short in the circuit that must be fixed .

Leaking intake plenum

I doubt a leaking plenum would cause it not to start. Usually a leaking plenum would cause an air leak and make the engine run too fast.
Any trouble codes stored ? Will it start using carb cleaner spray ?

Seems like you replaced everything on the ignition but the cap. Sounds like a good place to look to me.
Look for burn marks around contacts.

Starts but will not stay running

My guess would be intake gaskets leaking. Did you take the intake off, or do it all in one piece?

Possibly a leaking head gasket. Water/antifreeze seeps into the cyllinder when it cools off, and then it won't fire properly until the coolant is blown out the exhaust when you start it. Let it warm up with the rad cap off. If you see bubbles continuously coming up to the filler hole, you have a head gasket problem. Do you have to add coolant monthly, or weekly?
If you're lucky, it could be just a spark plug that doesn't want to do anything until it warms up, or it could be a valve.
