1995 GMC 1500 Pickup Question: engine shutoff shortly after start

 

Question

Recently my truck has been shutting off shortly after starting it up. All of my gauges read wrong when this happens. My battery says it's only a quarter of the way charged, temp is all the way in red, gas is on E, and oil is in red. I can keep recranking my truck and eventually it will crank normally and gauges will read right. Last time this happened before today was about a week and a half ago. It returned to normal after 3 cranks but today I've tried about 5 times and still no luck. Engine was cold this time but last time it wasn't. Before the gauges started to mess up the same thing would happen, crank truck and put it in gear and immediately shut off. I could turn starter for about 10 seconds and truck would start and run fine but it would shoot out a small amount of white smoke from the exhaust. I've checked my alternator and it's not the problem but battery check shows battery is bad but I don't think the battery can cause these symptoms. Any help or advice would be greatly appreciated.

    The gauges are an instrument cluster error. The Cluster is also involved with the charging system for your battery. For the start and die, make sure that your ignition switch is ok and not dropping a power source to your engine when you go from start to run.

    here is a repair info site that will have the wiring diagrams for your GMC truck.

    The problem is solved. I carefully examined my battery a few minutes ago and realized the negative ground wire was barely touching the post. After securing it in tightly my truck cranked up fine and gauges are normal.

    P.S. The link you provided is terrible. Why would anyone pay for a manual stuck on a computer when they could get a hard copy for the same price???
