The EFI main fuse under the hood keeps blowing on my '89 Xcab I have chased the wirer on the right side on the tuck and found no chaffs in them. From the manual the only thing I could find that I though could draw more than 15 amps was the fuel pump, so I just replaced that and I have the same issue. I can get about 1/4 mile and it pops. Any Ideas on where to go next? This fuse seems to provide power to every sensor and injector. Anyone had this happen? Ideas? I would hate to have to start throwing sensors at it. Thanks for the help in advance.
