Starts but after a few seconds shuts off. To me it seemed like a fuel issue. Replaced: fuel filter, fuel injectors, distributor cap, rotor, ignition module, TPS (throttle position sensor), ECM (electronic control module). Error code is 22 (low voltage from TPS to ECM). Jump the TPS reference signal (five volts over voltage) wire to the TPS output wire (sending signal back to ECM to check that this wire is not broken) I then receive an error code of 21 (over voltage) so TPS wires appear to be okay. Once I restart the truck (and it shuts off) the error code reverts to 22. Totally confused and lost, any help would be greatly appreciated. Thanks in advance.
have the same problem?
