Yesterday the truck started up ok and I pulled it into the drive from the garage. ran ok, came back to start up a few minutes later and it went wild.
here are some of the issues besides not starting: clicking relay under the dash, rpm gauge went up 1000 and bounced wildly, speed gauge moved, strange buzzer noise.
checked and charged batteries, checked some fuses under the dash, batteries read 100% charge but after I tried to start the batteries read lower then quickly charged back up on 2 amp cycle charge.
i did move the truck from my level garage to my inclined driveway, and I was getting low on fuel the night before. should I check for no fuel issues?
do you by chance have a cracked windshield? A small leak onto the PCM can do some really weird things with these trucks. A CPS issue could be the problem, but I don't recall ever getting any buzzer noises, just random stalling issues.
Sounds like a loose or dirty cable... Or even a bad ground SOMEWHERE... Do you have a chip/tuner? Either way good luck and welcome to FTE!!! Let us know what you find!
