Intermitant starting issue

Again the start signal voltage should be measured and shown to be the cause. Yer puttin' yer boots on before looking out the window for rain.

Definitely sounds like a problem with the starter or associated wiring.

regardless A start relay is a good idea.  It'll make your ignition switch last longer.

Start signal is fine. I am pretty sure I found the issue. My key cylinder has been giving me some issues for a couple of months (the return spring was not working right) so I swapped it out also knowing it might be related to my problem. I've been driving a lot for the last several days with no issues. Not a guaranteed fix as intermittent is a bitch to track. But I've driven a lot and no issues thus far.

While there are plenty of work arounds, this bypass being one. I generally agree with Mike that it should be correct rather than bypassed. There are fuses and what not in the correct line and I generally don't like going around those. The new key seems to have done the trick. I've considered a start button instead of using the key as these cheap ass keys keep breaking. But I still think going through the stock relay is correct.

the later Nissans went to a Hotstart relay from the factory that worked off the key switch.

if you have a new switch it might work but as these vehicles get older more corrosion happens and the resistance goes up and happens again. that why Nissan added the reley triggered by a low voltage relay.

I didn't want to do this either and got a new switch. I added a Ford relay on my 521 and NEVER  installed the new switch. Now it seems my cheap ass Orileys starter is lasting longer than 2 years.  So I was getting rid of good starters. as O Rileys said they were good but I thought they were fullof shit and swapped them out anyways(lifetime wareenty)

It's not a bypass. You still use all your stock wiring, except you trigger a relay with it instead. Relay then fires your solenoid with power directly from the battery, instead of running 10-30 amps through your ignition switch.

Done properly it's a properly fused relay powering the starter solenoid (which is basically a larger relay itself)

16 gauge should be more than enuff

 

most people don't add the fuse
