My father in law was killed several years ago and my wife begged me to get his expedition. Prior to his death it had a little shake like bad coil packs. I finally agreed and brought it home. A new battery and some fresh gas I started it and drove it into the shop. All of a sudden it cut off like the key was switched off. Turning the key would turn it on but not crank. I found bad pcm fuse, and no ground on starter relay. I pull apart the junction box and find a bad spot and solder a 22 Gauge jumper in. Reassembled, still doesn’t crank. Anti theft does not blink fast, I can spin it over at relay with jumper 30/87a but no injector pulse. Will start on starting fluid. Please help, she is heartbroken and my knowledge is Chevrolet. Best I can figure is no ground from pcm at junction box.
