I would check the fuses in the engine fuse block it is near the fill spout for the windshield washer fluid. If all the fuses are good should be three fuses total (2) 50A and a 200A . I would then check the ground cable under the drivers side between the transmission and the drivers side fender. If it is corroded I recommend doing the additional chassis to engine ground that many other members here have done.

Above is the link to the additional ground cable to the engine.
