Intrepid 2.7 no start after engine swap
I just put a 2.7 engine from a 2002 intrepid into a 2004 intrepid. I drove both cars into the shop. Both have the NGC control systems (The connectors to the PCM do have different color coding). It has the black key so we should be able to rule out skim issues.
It is not setting any codes, Even with the sensors disconnected and there is no RPM showing up on the scanner when cranking.
When I first checked it, I could get it to fire with the cam sensor unplugged but now it won't even do that.
I tried swapping the cam gear/tone wheel but that did not help. Based on advice from others, I pulled the engine again and swapped the flywheel to the 2004 flywheel. (The two flywheels look identical). I double checked the chain timing and swapped both the cam & crank sensors. I even tried the 2002 PCM but it still won't fire.
I now have all of the 2004 parts on the car. I have checked all grounds, verified power to the coils and injectors and continuity to the PCM but am not getting a pulse from the PCM to the injectors or coils.
Yesterday I broke down and took it to the dealer but they couldn't figure it out either.
They said that they can establish communication with the PCM and read the VIN# but nothing else.
The car does have an aftermarket remote starter/alarm/keyless entry but when I called the company, they told me that the only system it interrupts is the starter and since it will crank, it shouldn't be an issue. All functions are working ie..it will lock/unlock, sound the horn and crank remotely.
Any help would be greatly appreciated,
