Hello Scotty, I have a 2002 oldsmobile silhouette, 180,000 miles, automatic trans, 3400 V6. Parked the van 3 months ago, got in and she won't crank. Theft systems checks out, lights on the dash light up as they should, and disappear when I turn the key to crank as they should, but no noise whatsoever for cranking. Fuel pump primes each time, I checked every fuse, and relay as well as the sockets they plug into with a multi-meter. I had the battery checked, PCM works with scanner and no codes. I jumped the stater terminals and the starter works. So I turned the key to the run position and cranked the starter by jumping the terminals with a screwdriver, she won't run. Is there some signal that the PCM isn't getting to allow the engine to run, by me trying to start the car by jumping the starter? I know that the PCM has the ability to shut off the fuel injection after 3 seconds of if doesn't detect the key, is there some other signal that allows the PCM to shut off the injectors? I'm at a loss as to why I cannot get her to run.
