well depanding on ther truck if you have a ford with a starter solenoid on the pass firewall when you try to start it with the key it should make a click sound if not you have a bad starter solenoid if a Chevy and your jumping it from the starter it self you have a bad solenoids i would replace it Chevy you can some times buy the solenoid it self but i would buy a new starter just in case
connectors are loose
Here are several answers and opinions from FAQ Farmers: * The starter drive is a little gear unit that gets pushed into the flywheel teeth to rotate the engine during starting. Once the engine picks up speed, the flywheel starts turning faster and spins the starter drive backwards back into the starter. Either the starter drive is bad on your car, or the solenoid that pushes the drive forward is bad. Either way, you're looking at buying a new starter. * Assuming from you description that you mean that the starter is staying on after you start the engine. It depends on the configuration of the solenoid and starter. Sometimes the solenoid can be held down if you have a stuck keyswitch or if the solenoid contacts have fused.
bad solenoid,& starter
It would be the smallest wire (aprox 14 gauge) attached to the back of the starter solenoid.
It has either . jumped timing
your ignition switch or the starter solenoid is bad try jumping the solenoid instead of the starter, if this does not work, then change solenoid
I jumped with a start at the loud noise but it was merely a book that had slipped to the floor.
Bad solenoid, bad ground, faulty ig. switch.
One possibility is a defective lock-up torque converter solenoid. If it runs and idles fine in then this would be what I would check first. Disconnect it and if it then stops stalling in drive, you have found the culprit.
I would check the idle air solenoid on the intake manifold
Yes, a broken chain or chain that is worn so bad it has jumped a tooth or 2 can cause the vehicle not to start.
