Change starter now van wont start - Express Chevrolet Cars & Trucks

Scan test engine for any codes

Turn the headlights on and watch them while the key is turned to start. If the lights go out, one of your cables or connections at battery or starter is not good. If lights dim a lot but stay on, possibly a bad starter, it needs testing. If lights aren't affected by cranking position, turn lights off, pull the small wire off the starter solenoid, hook up a test light to ground and to the solenoid wire. Light should come on when key is held in crank. If it does, likely a bad starter solenoid. If no light, then the start circuit from ignition switch to starter solenoid is not working. Check for power out of ignition switch on the start wire with key in crank, to begin with. If powered, switch is good, need to check if neutral safety switch is good, and then check or swap in a new starter relay.
Post back with any results.
Good luck.

The starter is defective, it is a common problem. Watch the video below to see how to change the starter motor.

You could have a bad fuse, or, the ECM may be bad. the "ECM" is the computer.

MAKE SURE GLOW PLUGS ARE GETTING VOLTAGE.COULD BE PREGLOW RELAY.ANOTHER POSSIBILITY WOULD BE FUEL PRESSURE SENSOR AT BACK END OF FUEL RAIL.

Change the temp sensor to solve the problem

I would have battery checked/charged and/or replaced. Then starter, then alternator checked.

If you tried jumping it and it still doesn't start, then it's not your battery. There may be a problem with the solenoid/starter. Try tapping the starter a few times with a metal object (tire wrench or something), but not too hard. Then try starting it again.

sometimes when one replaces the ignition a small plastic part falls from the new ignition causing it not to fully engage-for fun turn key with a liitle firmness all the way to sart-sometimes with added pressure it engages-orthewise remove ignition for examination

check the small connector at starter for voltage when cranking if ok try the hammer test if starts bad starter (ie) tapping starter with hammer while trying to start.
