I have a 2000 Yukon, motor will not turn over. Has a good battery, changed relays and checked starter. Could the problem be in the security system?

There's your problem. You need to replace the alternator again. Please check out the instructions with the alternator.

And could you please give me a "problem solved" rating -- there should be icons below.

thanks...

SOURCE: how check relay window in my yukon denali 2002,

Look for bad wires. There may also be a bad door module. Most don't have relays anymore, just modules.

The next thing to check is the amount of corrosion at the other end of the heavy battery cables; any car exposed to road spray will eventually develop problems at the starter or where the negative cable connects to chassis or block. Any cable connecting these two should also be removed and cleaned.
Remember to ALWAYS disconnect the negative battery terminal first to avoid damage to tools and vehicle.

Any suggestions on one that will not start


If your saying the starter motor won't crank? Make sure battery has a full charge and connections all good. Check starter wiring circuits. I'd have to make sure security system doesn't have a problem?
If there is a starter relay, on load side of relay, one terminal is hot all the time, If you use jumper wire between the proper two terminals, on load side of relay, the starter should crank. If you try that, make sure tranny is in park or neutral and functional parking brake is set. With automotive relays, they have two sides, coil/control side and the other side is switch/load side that carries voltage to starter. Even if we get starter motor to crank, if security system is involved, it still won't start.
If you have proper voltage and ground at the starter motor and no starter action, I'd have to check starter motor.

Lots of power, dash lights up but no ignition power to starter, relay changed, neutral start switch changed, fuses good.


Well, looking at the schematic, there is the IGN A (Fuse 6) in the under-hood fuse block feeding power to both the ignition switch and to the NO contact of the starter relay. Turning the ignition switch to the START position sends this voltage thru the CRANK (Fuse 8) in the instrument panel fuse block and thru the PARK/NEUTRAL position switch, thru the starter relay coil to ground. This should activate the Starter relay and pass voltage to the starter solenoid to ground, activating it. One the starter solenoid activates, batter power is sent to the starter motor, activating it. If, as you say, the fuses are good, the starter relay was replaced and is good, and the Park/Neutral position switch was replaced and is good, then then only items left are the ignition switch itself, the starter solenoid/motor, or the wiring of the circuit.

No Turning of the engine: Starter tested~Good, Battery Tested~Good, Changed the Park/Neutral Switch, but still no response. When I turn the key, I get all the lights and sounds, but the motor will not even...


Change the actual ignition switch? Test light at starter signal wire while someone turns key to see if you have power at signal wire. Check all your grounds after that. Still nothing take steering column apart and change ignition switch .

My 2005 Yukon denali won't start, I have replaced the fuses, relays, the starter, the ignition switch, battery, and removed the alternator and had it checked. The truck still will not start without me...


My guess would be the anti theft security system. When this system starts to fail, it turns off the starter from the ignition. The fact that you can hard start it proves this.

2003 MERCURY THE BATTERY HAS BEEN CHANGED BUT THE STARTER WILL NOT TURN OVER THE ENGINE YOU CAN HEAR THE STARTER RELAY CLOSE


Had the same exact problem on my 2000 Sable. Checked ignition switch. Good. Replaced battery. No change. Replace starter. No change. Starter solenoid engaging when ignition turned on. What it ended up being was an $8 positive wiring cable coming directly from the battery to the starter. Even though it checked good with an ohmmeter.(good continuity) Under load, it became an open circuit. Thus, the 12vdc could not transfer to the starter motor. Save yourself hundreds of dollars and time with an $8 dollar cable.
