My 04 z71 will not crank after driving as the 100s of others on the net and GM refuses to acknowledge. It's none of the common problems as all the others its in or appears to be in the pass lock or anti theft system . I have a wire to my starter and I jump it off cranks every time that way .
JA: How many miles are on the car? Does the engine
turn over at all?
Customer: 150000 and no starter relay clicks all lights come on as normal but will not turn over
JA: What is the model of your '148000 Chevy?
Customer: 2004 z71 1500 5.3 Silverado
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: New starter extra ground straps Batt is hot new keys new relays all new fuses clean ignition key switch
JA: Anything else you think the mechanic should know?
Customer: After sitting over night it would crank it began after a few min to a hour to over night now it will not crank at all unless I use the remote then it cranks and runs fine . Also it effects the ac when it key cranks ac works but not so if I have to use remote
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Chevy Mechanic about your situation and then connect you two.
