Question about 1991 Toyota Pickup
This is an unfortunatly common problem with this vehicle, if my hypothesis is correct. Try this: disconnect the wiring connector going to the fuel tank, under the bed. Replace the fuse and crank the engine. If the fuse does not blow, then the power wire going to the fuel tank sending unit is shorted out to ground. I change about 15-20 fuel sending units a year for this exact same issue. Replace the fuel tank sending unit if the fuse does not blow. When you get it out, you will see the cause of the short, rust at the connection on top of the sending unit. Hope this helps.

You need to look for a short in the engine harness, anywhere that the harness rubs on engine componets etc. In the past 30 years of car work this is where the problem most often occurs.

Try replacing your efi relay, disconnect the relay and jump the side of the relay that opens and closes. there maybe a short in the harness here or the relay could be bad, either one will blow the efi fuse and keep the vechicle from starting
