sn A2h503400 dual fuel, no accelerator in either mode. Continuity wire check from terminal to terminal on 6 wire APP & 6 wires on TPS to ECU. Check for all recommended voltages at all specific terminal-ok. Replaced APP pot, ETC unit and ECU. Check ETC relay-ok suppling 12 volts to ECU. No codes-run scan with Hitachi hand set. APP shows to be working, 0.95v @ Idle, @ WOT 3.75v on both 1 & 2 Sensors. TPS 1&2 sensors shows 0.97v @ idle, 1.25v @ WOT (which on a working truck I've seen these voltages higher-which I believe is why I am not getting acceleration) I am not sure what else to check for, no acceleration, no codes, starts & runs relatively easy. Any help would be appreciated.
