Engine Mechanical problem
1998 Plymouth Voyager 3.3 6 cyl Two Wheel Drive Automatic

After swapping out a bad engine and driving it for several months, it just stalled and won't start. It will turn over and it is getting fuel. I checked the coil and it is working. I have changed the crank shaft positioning sensor, went and bought another running voyager and swapped out parts from it and it still won't start. I replaced the fuel pump with a new one. I ran codes and I had a 122 and a 340 code. But still cannot locate the problem. I had to clean out the catalytic converter to start with. I have now ran a ground wire from the timing sensor and the crank shaft sensor and that didn't work. When I try to crank it, it turns overs then it sounds like it is spitting back fuel or air.

Ok in order to be of assistance I first need to know the true codes. For vehicles 96 and newer the codes are P plus 4 numbers. Get me those codes and we will start there and see where it takes us.

Ok the codes are for one the p0122 is throttle position sensor voltage low and the other is for no cam position sensor signal at pcm. So you will need a scan tool as we need to know what the voltage going to the TPS supply voltage and we need to know if there is a CPS which is on the timing cover just below the thermostat needs to be checked to see if one it plugged in and check the wiring for any signs of damage.
