When trying to crank nothing happens. After removing the key out of the ignition the door locks do not work either from the door switch or the remote. The day time running lamps also stay on indefinitely. This can be resolved by pulling the PCM fuse. On one occasion the truck did crank but shut down after one second. (Twice in a row) Now it's back to doing nothing. One change---when inserting the key in the ignition and turning it to the first position, the ignition starts firing ( you can hear the coils hum) and the tach states 3000 rpm.
Tried to hook up a diagnostic reader but there is no communication. I got in the vehicle and slammed the door shut and it came back to live. Diagnostic tool connected and working---no fault codes. Vehicle cranked up and ran for 1 second. Everything dead again. Repeated this process about 5 times. Any ideas?
have the same problem?
