Ok. I changed my battery and now it won't even crank... Not even lights go on or radio.... Not even my alarm goes on.... The only thing that goes on is my electric fuel pump that I have it directly to the battery.... I checked all the fuses and no burned fuses..... Very confused right now.... Oh yeah.... 1988 22r...... Can someone help me or have any idea what the problem is???? Thanks...
I would remove your under hood fuse block and inspect the under side of it may have a bad or corroded wire . Check the small wire positive wire that comes off the battery and travels under neath into the fuse box buy the batt for power and connection And if u have a noid light tester or multi meter check hots and grounds
Happened to me on my Tahoe not too long ago. Turned out to be a loose ground on the battery end. There was a wire that went to the fender that somehow got loose.
