Code 42 and code 23 no run
Ok guys, Im about to stick a needle in my eye, that would be less painful. I posted up a week ago (https://www.thirdgen.org/techbb2/sho...hreadid=303895) and thought that I fixed my problem, bit I didn't. The original problem was the the engine completely stopped running, found out that there was no injector pulse but I did have spark so I replaced the module and everything was wonderful.......until it ran for 10 minutes straight and died again. This time it gave me the code for the module and a code for high tps voltage. I thought it was a coincidence and possibly a bod module because I didn't by an AC Delco one. Today I got my shiny new AC Delco unit, threw it in, took it around the block, pulled in the parking lot and died. This time, same conditions, no pulse but I do have spark, but I only got a code 23 for high tps voltage. Im going crazy.... someone please help!!!
