Anyone know where the location is of the infernal thing?

My truck keeps throwing a P2509 and I need to check out all the connections to rule out a possible short that would give me this code. I'm thinking its a short , because if the PCM was bad it wouldn't even run right?

She revs fine right to redline from idle , but as soon as I put her in gear she won't run past 42 mph. chuggin smoke and horrible fuel economy.

She is also throwing another code that indicates not enough fuel reachin the injectors.

I'm inclined to believe that this is a result of the ECM also , as to have both of them happen at the same time same day , just seems unlikely.

Anyone else have this problem? - I've checked the batteries and the voltages are fine and checked all the obvious grounds. But need to check the connections to the PCM if I can find the damned thing.

HELP!!


Thanks

 

You should find the PCM on the drivers side of the engine, lower front.
