My 2005 Grand Caravan with 3.3 will not fire. I have followed all checks recommended on the forum. If I go to the salvage yard and get a pcm from another van and install in my van will it work? Will it require reprogramming? Just at wit's end, don't know what else to do other than pcm. As stated I've replaced crankshaft and cam sensors, replaced coil. checked wiring for voltage. Thanks
