I purchased this truck last weekend and it runs great. The thing is, when I got in it this morning the fuel gauge was not working, the ABS, brake light, and low fuel indicator lights are on. When I first start it if I keep it idled high the ABS, brake, and low fuel indicator lights will stay off but the fuel gauge still stays on empty. This all started at the same time. Any ideas on what the problem might be or where to start looking????? Any help would be appreciated!!!!!!

 

First thing I'd suspect are the grounds. These trucks are notorious for have grounding problems. otherwise it might be in the PCM . The fuel guage though could be a problem on it's own. The sending unit is notorious for bad contacts. Can be tightened up, but about $50 for a new one. Loosen the bed bolts and just tip it up in the driver front corner to get to the tank unit. Or drop the tank, PITA.
