So, my TB just died the other day. When I try to start it, it refuses to turn over. It sounds like something start to spin and just stops. The weird thing is the RPM needle. It jumps up and down constantly, even when the truck is just in the on position. I disconnected the negative and cleaned the throttle body this afternoon, but still no luck. Has anyone heard of something like this before? Could it be the starter? I've had this problem before - a couple weeks ago, I had a slight "bump" with a stone pillar and the TB would not start. I got a jump from a tow truck and it still wouldn't start. After about 10 minutes or so, it started up. I drove it to the mechanic and he tried it a couple times. It would start 80% of the time he tried it. Then when I drove it home, the next day it seemed to have no problem. Now it's about two weeks later and it seems as if it has succumbed to whatever it was suffering from weeks ago. Any advice?
