In this video I go over how you can perform a no crank no start diagnosis, whether all you hear is a click or even if the battery tests good but won't start. There are tests you can do to verify all the different components of your starting system. Including your Neutral safety switch (NSS) or Clutch pedal position sensor if you have a manual transmission, your starter relay, the connectors going in and out of your starter including the A, B and S terminals and your Ignition Switch.

      O’Reilly and AutoZone can test your starter for free. Due in part that in the hopes that if the starter you want tested ends up being faulty that you buy a new one or reman one from them.

      Excellent video. I have an issue that is intermittent. It cranks most of the time. But sometimes i will turn the key and it wont do anything it will be like it wants to crank for a second then it doesn't anymore. Or like most of the time it just doesn't do anything. And I turn key back and forth a couple times and then it works. I am wondering what this issue is as I would like to fix it before the cold hits. I'm going on to watch your other video right now but i don't know if that's the description of my issue, so Any help is much appreciated ! :)

      @Diy_Automotive It was actually both. But i figured it out. It was the wire going to the soliond, the post had come loose and was jumping the current and killed the wire but cleaned it up and tightened the post up and started so fast and easy.

      Is it a no crank issue or a crank no start issue?

      Great video. My 1992 Chevy S10 , after no notice at all, just failed to do anything when the key was turned. Had interior and dash lights, head lights and all, nothing at the key.
      Don't hesitate to use a little force with your hand, when checking connections. The solenoid Positive post that connects to the battery's positive cable. The cable was TIGHT, but the solenoid cap was able to move on the top of it. I just happened to be able to wiggle the battery cable and the entire cap of the solenoid started rocking. That was the culprit faulty solenoid. Done and Done... Thumbs ^ and Subby....

      Awesome video, I had power at my starter but not my signal wire when trying to crank. After looking around the motor for a bit I noticed the shift linkage popped off, so if anybody ever has no crank that's another thing to check

      2001 Nissan xterra, battery is good, replaced both negative and positive cables, starter replacement with a remanufactured one. It starts most of the time once in a while I here a click and no crank. I tried wiggling the signal wire but I didn't see a change. Any ideas what it can be?

      Nice the starter is up close and personal, I'm working on a 2004 Mustang, (NOT MINE, it's the wife's) I would have run it into the lake by now, BUT I drove it for the past 2 days and it started fine. Stopped at the bank, came out and just a click. I'm guessing it's the starter wires at the starter because the battery terminals are clean and tight, and I checked the fuse and relay. I mean if it was one of these, I wouldn't even get a "CLICK" RIGHT??!! I'm old tired and pissed off, I'd pay a good mechanic to look at it, but I'm guessin I'd have better luck finding Jimmy Hoffa.

      Great vid everything right on. Only thing I would add is checking your neutral or clutch safety switch should be higher on the list. Sometimes cycling though gears or putting car in netual is enough to start it. If manual sometimes pumping the clutch petal a few times is enough to start the car. I'd try that after I check the battery before the fuses just because it's so easy to try. It's even easier that checking the battery though I'd check battery first because it's so common.

      How to prevent battery corrosion on a battery post? The battery post corrosion can be caused by a loose connection. Corrosion can drain power out of a battery and shorten its life.
      If battery corrosion is present on the positive battery terminal, this is a symptom of overcharging. Generally, if the corrosion is occurring on the negative terminal, your system is probably undercharging. Clean the terminals and post. Please use disposable gloves. Mix 1 tablespoon of baking soda with 1 cup of very hot water. Dip an old toothbrush into the mixture and scrub, wipe down and dry with a paper towel for each post and terminal.
      The reaction between baking soda and water mixture and the acidic corrosion on the battery terminals will neutralize the acid, making it safe to handle.
      Before winter starts, disconnect the terminals and clean them with a wire brush. First you reconnect & tighten, then smear lightly with petroleum jelly. The jelly will prevent corrosion and help keep the battery cranking all winter long. Thanks for sharing your video. βœ”πŸ™‚

      Great video. Very helpful. Helped me rule out a bunch of items ... in the end a mouse had chewed thru a wire to the transmission neutral gear safety switch. It was about the last thing I checked -- but your video was helpful to get me there.
