Your starter is operated using 2 sources of power (refer to sketch below). Power source #1 comes from the ignition switch via a starter relay. This power source operates the spring-return solenoid which serves 2 functions: 1) it thrusts the starter driving gear forward to engage the flywheel to crank the engine, and 2) it closes a contact which connects Power source #2 directly from the battery to the starter motor. If the voltage of your battery is too low, Power source #1 will not be able to hold the solenoid in the forward position against the spring within the solenoid. In this case, you will experience the machine-gun noise from the solenoid.
Per your description of the problem, I suspect the contact in your starter solenoid is failing. With a marginal contact, you will have to repeatedly operate the solenoid until it hit the right spot to send enough Power source #2 to the starter motor.

Back in the day the contact point on GM solenoids would wear down. To correct, all one had to do was take the cover off the solenoid and turn the contact bolt 180 degrees. It was so very simple. Also, simple was removal of the starter/solenoid from underneath the car. I can't count the number of times I went through that with a variety of late '60s GM muscle cars.

On the Maxima, many people said they hit it with a hammer (when I say hit, tap), and it would be good for some time. It's always a shame to replace these parts because short of rebuilding ourselves, the replacement is not as good...imho. What I found defective over and over with the AC Delco replacements was the field wire cracking that goes to the solenoid...joke. They were "brand new.."
Not the battery. New battery installed. Today it failed to start 3 times. After a lengthy session at a restaurant I opened the hood, took the cover off the fuse box by the battery and tapped on all the items.
It it started the next crank.
Got it it to the mechanic. Would not start when I tried. The mechanic got in and it started right up. First crank.
I’ve r/r a couple of uz3 starters. A Toy/Lexus tech or local shop experienced with Toyota V8’s or just a plane good tech at their shop is a piece of cake. Bad juju to the home Wadell Wilson with limited time,tools,supplies or knowledge. When you remove or disturb just about ever hose of the vacuum system and fittings you can make a lot of work for yourself. You want a new Denso starter and a warranty from a shop. Money well spent on Toy/Lexus V8 starters.
