Intermittently not starting

Good afternoon,

Do you have a voltmeter or test light to do some checks on the system to see if it is either the ignition switch or the starter solenoid itself?

We need to do some checks at the relay. I attached a diagram and the relay so we can do some checks.

I do not have a voltmeter, but I'm thrilled you came back so fast and provided diagrams! Thank you Roy! However, I'm not a mechanic. I have, on occasion, fumbled my way through simple repairs with some success only because I'm tenacious enough to get it done by Google searching and watching videos. I wanted to have an idea as to what might be problem before I either YouTube it, or take it in to a professional. If it's the ignition or starter, it might be out of my range of repairing it on my own. Replacing a battery, a fuse, or replacing an easy to get to hose, topping off fluids, or something else simple, is the extent of my repair experience.

Is there any other way to determine the problem without a voltmeter?

Okay, the most common failure is the ignition switch itself. The inside wears out and the contacts only work part of the time.

The starter motor itself is also common but voltage needs to be tested to the solenoid to verify.

Lastly, wiring. That could be the issue but testing will confirm.

Remove the following parts to make room and take out starter
through the clearance between body and frame.
