We have a '93 Toyota PU that was running fine. It quit while driving down the road and wouldn't start again. Got it home and found there was no spark. Replaced the coil, truck started and ran for 15 min.then blew a fuse. Everytime I replace the fuse then turn the key to start the truck a 15 amp fuse blows.
What should I check next?

It is the EFI fuse blowing.

When you turn key to On it blows right-BTDT

Disconnect the mass airflow meter connector and also remove the circuit opening relay-put another fuse in it and see what happens. If it continues to blow-check the red and white wire going to the computer box pin out +B1 for shorted to ground.

To make things complicated the fuel pump will not come On.
