2002 Dodge Ram

2002 Dodge Ram V8 Four Wheel Drive Automatic

4.7lt-head gaskets were redone and new timing chains put on, all the timing marks line up 100%(triple checked), keep getting code P0358. Swapped the coil with cylinder 7, no change, swapped injectors, no change, try a brand new plug, nothing. Compression is good. Customer says the light wasn't on before but the truck was half ripped apart before I got it. Any ideas where to start looking or testing?
