Truck turns over, won't fire up. 1 1/2 yrs agao had (4) different used/rebuilt computers put in until the last one worked. Now it's acting the same. No dummy lights come on indicating a problem, probably cause it won' crank.

All fuses looks fine.

It all started last Sunday. Truck outside in cold weather. Jumped in it and battery was dead as a hammer. Charged it, got it cranked, let truck run charge battery. Drove to work, M-Turs. Wed. Jumped in and battery dead again. Since then can't get started. Battery is good NAPA siad.

Time for another dang ciomputer. I was told there are no NEW ones, all rebuilt?

Thanks,
M

Sounds like your problem is two fold. Correct me if I'm wrong. Is the battery being drained as the vehicle sits? If the battery is charged up, does it crank but won't start? If yes to the "cranks but no start" are you missing spark, injector pulse, fuel pump pressure, or all of the above? Also, is your charging system putting out? Please advise.

First time may heave left on interior lights. Second time drained, I couldn't be stupied enuf to have made the same mistake twice?

As far as I know it is charging the gauage seems to indicate so. Th nattery is OK and fully charged and truck trns over but will not fire.

I can put on the hot lead and see if it drains the battery down? When I do put it on, I hear a slight hum for a second ot two under the hood. When turning on the key, I hear no hum from the gas pump kicking on, but ever recall hearing that when it was running either.

What now thru process of elimination? Thanks.
