Nothing meaning no cranking or nothing as if the battery is dead?

ITurn key, clicking sound, no turn over


If it won't crank over, it's a problem in the starting circuit, not the ignition circuit. Check your battery and starter for clean, tight connections. Listen for that click to see if it comes from the starter solenoid on the starter-maybe have someone try to start it while you watch and listen under the hood. If the click is from the solenoid (and not from the starter relay), then the starter is not getting full battery power to crank (bad connection), or the starter needs to come off and be tested.
If the click is from the starter relay, you could pull off the little purple wire to the starter solenoid and see if it has 12 volts when the key is in start position. If you have power there in cranking position on the switch, the solenoid is bad or the starter may be the problem-again, it will have to come off for testing. If you have no power at the solenoid in cranking position, the circuit from the ignition switch to the solenoid is not working. The start relay and the neutral safety switch (or clutch switch if manual transmission) are in the starting circuit from ignition switch to the starter solenoid. Good luck.

94 GMC won't start, lights & horn work. Also pulled starter and had it tested, tested OK.


If your starter and battery are both good chances are your ignition switch is bad and will not allow power to your starter. If your replace the switch it should solve your problem. I hope this helps and if you have any other questions please feel free to ask.

My transmission felt like it was slipping, then my truck, a 1995 GMC Sierra C1500,lost all power and dies, would not restart, all dash lights came on and sounded like flashers were on also with the key OUT...


if there is any corrosion between your battery cables and terminals you need to clean them real well i have a 1995 chevrolet silverado and i just delt with a similar starting problem there should be 2 cables attached to the positive (+) side pull the 2 cables apart and clean in between them real well the next cheapest thing woul be the starter the ignition switch is exspensive

How to replace 2004 sierra ignition


i have a sierra also... the wheel, shifter cowl, etc. has to come off to replace the ig. switch. good luck
ps... did you try putting the shifter in neutral and try to start it? there is a safety switch so that when it is in gear and running, so that the starter cannot be engaged..its best to have it checked out at a garage. bye...

Replace starter on 1992 GMC Sierra pickup truck


First thing unhook positive battery cable, unhook main cable on starter selanoid and small wire on selanoid (there may be 2 small wires) There may be a bracket on front of starter that has to be removed, and then the 2 main bolts that hold it to engine block and it should come out.
