Trying to do a compression test and truck is doing this damn random no start thing once again. wont start with key or jumping starter relay under hood. Someone has to have an idea out there......... It's random and starter is less than a year old and everything else checks out that I know of. Is there any other relay I should know about. Not sure if it is my less than year old starter or not and sucks cause I got it from db electrical so I would have to send it in and be without a starter for them to check it out:doh: On top of all things compression readings are looking not good at all.:doh::doh::doh::doh:
