Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome to just answer. Was this engine swap done with the same year and same engine?
Gotcha. Do you have a scan tool so you can check cam and crank sensor sync status? ..
Ok. You may have a shorted 5 volt sensor. Disconnect all sensors incuding the transmission connector. See if the code reader will link up. Let me know.
Well not the ECM connectors, leave them plugged in. Disconnect the distribuor (cam sensor) , crank shaft position sensor , Throttle Position Sensor, Map sendor, coolant sensor and transmission connector on the side of the transmission. Check to see if the code reader will link up after disconnecting the sensors one st a time. If it will, then thst means thst the last sendor you disconnected may be shorted and should be replaced. I hope that mskes sense.
A shorted sensor will cause both. A no start and a no communication with the scan tool. Let me know how it goes tomorrow. I will look for your reply. Have a good evening!

Sounds good! I will look for your reply tomorrow.
Hmmm, did you disconnect the connector at the transmission also?
Oh, well speed sensor maybe?
Well if it has one on the trans, then it should be on the rear left side of it.
Let me see what I can find. Am at a memorial service, but when I get home I will get some information to you.
Ok, well at this point, find the 5 volt reference wire coming out of the PCM connector. Cut the wire at a point to where you can splice it back together. Now turn on the key and see if you actually have 5 volts on that wire. If you do, then we must have a harness problem. If not, then it must be a voltage regulator in the PCM. Let me know if you need the PCM pinout connector info.
Wow. Very strange. Check continuity between the wire coming out of the PCM and the terminal in the connector. Maybe a bad crimp on the terminal.
