i have been chasing a random no start issue with this thing for over a year now. always had WTS light during this. changed the CPS today. did not have WTS light after that. checked all fuses and breakers. was messing around with the PCM relay trying to get it out and pulled the removable cover off.(this van is a bear to work on). reached in with a long needle nose to grab the relay and had a couple sparks. (uh oh,now what did i burn out?) nothing. WTS light started working and truck fired up like brand new. what did i fix without fixing it? i fear another random problem with this thing!

 

Sounds like you just cleaned the contacts on the relay, LOL
