Hey Guys,
I need some help, '04 Venture w/SES Lt on and runs rough. Pulled no. 1 spark plug and cranked engine - Nice bright blue spark, that rules out the ignition system. I want to check the resistance across the injector before I pull the top of the intake manifold off but the Haynes manual only give wire colors for the injector into the PCM, No. 1 is black. You know how many black wires go into the PCM, I counted at least 9! So then I looked for a cavity in the PCM that had all of the injector color wires, it's impossible!
So my next best bet is to throw it open to you guys, you've never let me down before. If anyone can tell me what pin numbers on the PCM the injectors go to I would appreciate it.
Also if anyone has any insight into code P0301 I would also appreciate it, at this point I am down to Injector plugged or electrical failure, wire to injector open or shorted, or failed PCM.
IMG gasket replaced about 6 months ago, no coolant loss and no oil loss. If I wind up having to take off the top intake I am going to re-torque the lower intake just to be on the safe side.
Any help? You guys are the greatest. TIA.
