Hello,
I am still learning my way around this site. Thanks to Roadie for his guidance and help. I have a 2002 GMC Envoy 4x4 4.2. Bought it new, it has 225000 miles on it. I do most of the work myself. This truck was first model year production, built in Oct. 2011. I am not able to start it. It is coding 1555 & 1556. I went to a You Pull it Yard and got a gas pedal with sensor out of a wreck. I was going to another yard today to get a TPS. I know this is a shot gun approach. I do not know how to check these parts that are on the truck. I just put in fan clutch number 4 and was careful about not destroy plugs or pinching wires. The ignition lock froze. I used WD40 and a gentle tap from a rubber mallet. The key now turns and the truck was starting fine before it quit. The steering wheel does not lock after my mallet approach. I have checked fuses under hood and seat.
I would appreciate any and all input. I am over my head. I would like to keep this truck for at least another 100K. Wondering wether the tampering with the ignition has any thing to do with this current situatin. I replaced the ignition switch about 50K a go.
Thanks
