My truck won't engage to turn over to start. We replaced the Battery, starter, and battery wires, and it still won't do anything. All the lights are working fine, heater and ac are blowing. It seems like the key isn't turning as far as it should in the tumbler, but that could just be me imagining it. Otherwise when I turn the key it just lights up the dash and moves some gauges around, but doesn't turn over. What should I check? How hard is it to put a new ignition in?
I would say it is entirely possible that the lock cylinder is not turning far enough to engage the solenoid circuit. Common problem. My 92 C1500 and 94 K1500 have both done the same thing. Replacement is a breeze if you have the tools (steering wheel puller, lock plate remover and torx bits for removing the lock cylinder retaining bolt) 1. Remove steering wheel. 2. Remove lock plate (held on with spring clip).3.Remove screw that holds turn signal linkage and remove linkage 4. Remove screw in 4 way flasher knob and remove. 5. Remove 3 screws that hold down turn signal switch and gently pull switch out of housing about 2 inches. 6. Remove little white plastic switch that is in the way of the torx head bolt that holds the lock cylinder in. 7 Remove torx bolt and pull lock cyinder out of column. Reverse operation to reassemble. Good luck. Part is less that $20 at any parts store.

Voltage drop? I'm guessing you don't have a voltmeter, so turn on the headlights and observe them as someone tries to start the truck. If the lights go out, bad connection at battery, starter, or ground. If the lights get dim, probably the starter-it's drawing power, just not working. If the lights don't change, check for power going to the starter solenoid on the small wire on the starter; voltmeter or test light, check if the small wire to the solenoid has power when key is held in start position-in crank position. There should be battery voltage there when the key is turned to crank. If so, the starter or solenoid is bad. If no power there to solenoid, power is lost somewhere between ignition switch and the starter wire.
make sure all grounds are clean and area of metal that ground wire's bolt to are clean and rust free if that check's out ok there could be a break in a wire going to the starter and most starter's have two wire's going to them and those both need to have power going to them one drop's off when key is turned to starting mode volt meter work's good for this or test light or the starter could be bad
Hi Vernon, There could be a number of different reasons why your vehicle is failing to start. The battery voltage could be dropping during start and become unable to engage the starter motor to turn the engine. You can check this by trying the key with the head lights switched on. If the lights become very dim, you'll need to check the battery, meaning clean the terminals and then try to start with a jump from another battery. If you achieve start up and it fails again the following morning, you will probably need to replace the battery. There could be a problem with the starter relay or a loose contact for the starter motor, most lik3ely the one connecting to the soliniod. It would be good to know some additional information, such as does a clicking sound come from the starter when engaged? Is there a perceptible drop in voltage output when the starter is engaged? does the enine turn at all? Try what I've suggested and if that does not solve the problem answer the questions and let me know anything else which you may think is relevant. Regards John
It attempts to turn over but won't catch and run ????
When you turn the key to start does the starter engage an spin the engine ? This would be a crank no start condition . If the starter doesn't engage an spin the engine this would be a no crank no start condition . Sorry to ask but i have only been an auto tech for thirty years an have heard a lot of different discriptions for these simple actions . crank no start or no crank no start . Very different diagnostic procedures . So when you turn the key to start , does the starter engage an spin the engine ,but won't start an run ?
No it doesn't mean that you have a problem.When you cross the lugs with a screw driver no matter whether you have the key on or not it will still engage the starter.The reason being that you have the hot wire from the battery going to one terminal and your ignition switch on one terminal.What your basically doing is bypassing the switch and directly energizing the starter.A good way to test a starter is to remove it from your truck hook up your battery cables to your battery.Be very careful when you do this.Hook the ground to the starter casing and just touch the hot cable to the battery lug on the starter.This should engage your starter.You might want to take a look at the fuel delivery system for proper operation.
