Hey ya'll 178K, 4x4, 5.3L Late last week, left SWMBO stranded in town when it died. Started when the tow truck driver got there, decided a tow was prudent anyways. Good call... Started yesterday, ran for about 20m before dying This morning, hooked up fuel pressure gauge, 55psi even after it died (appx 30m), but no spark. Checking the crank sensor now (starter coming out). Any other suggestions while I dig into this? SWMBO has promised me a hella dinner if I can get it running by then. Are '01's required to go through the crank relearn procedures I was reading about (I have a ScanGauge II, don't think it does crank relearn).
