'99 Jimmy fuel pump won't turn on with 12 volts.
The car turns over but won't catch, I've tested a couple things now and am now looking at the fuel pump. Putting direct power off the 12 volt battery won't activate the fuel pump, but using a 9 volt battery will turn the pump on. Is it just a bad fuel pump? Or something else?
