OK, The truck is totally stock with no extra electronics. When the key is on all dash instruments seem OK, and yes WTS comes on properly. The scanner tool says communicating with ECM and reads no fault codes. The key switch will not work for trying to do code reads, it has in the past? I cracked an injector and had no feul while cranking? The ECM and PCM were sent to "Auto Module Source" and they said the ECM was fine but repaired the PCM?(this doesn't seem right).There is feul being pumped up to the filter, the truck had a factory recall when new and a new lift pump installed in the tank. Is there a way to be certain if the pump is the problem? Thanks.2002 ,5.9, 4x4, 5 speed manual( completely stock)
