    After daylight ck. wires to eng. for rub spots, the ft. sensor on L side near air comp. can make eng do stumble or just shut off with no code sent to dash,look at fuse inside dash for ecm power, you have a place where a gauge can be screw in to ck. the pressure at hand prime pump that a sensor would be to run dash gauge if it had one?
