Unhappy It's my starter, right?

Ok guys it's actually getting a little cold down here in GA(at least for us in GA), enough to say that I think my original starter actually needs to be replaced but I'd like a few other guys with the same kind of truck to ensure me it's my starter. I own a 1991 D21 2.4 RWD base model, no bells or whistles other than my stereo and a few led upgrades. First, it will crank when it's above around 40f. Last year I tried to replace it but found out that my battery was bad and it kind of took care of the issue but didn't fix the starter(obviously). Secondly, when I try to start the truck when it's cold, I hear this whine that sounds like the solenoid is trying to engage the starter motor but nothing happens. Not to mention there is rust all around(as expected) the housing which, in my opinion, only implies that the guts are probably rusted too. My only issue is why it will not start in cold weather(near freezing) but will start in warmer weather. My father swore up and down last year that it had everything to do with my battery terminals and a grounding issue. However, I have replaced not only the battery, but the terminals as well last year, as specified. Did a battery test after a failed start and it was 12.47v cold, which is a good charge. Am I over thinking this and just need to replace the starter?

Probably has a hard time in colder weather because there is more resistance on the wires. If the starter is original, it's time to replace it, get a NEW starter not a reman, unless you like replacing the starter.

You could try a jump start and see if that helps; if it does, suggests a battery issue.

However, what you posted above - is that a whirring sound but the engine doesn't spin? That sounds like the starter motor is spinning but the solenoid is not pushing out the gear enough to engage the flywheel teeth.

So I think it's time for a new starter just from what you posted, yours is either intermittently bad or on its last legs.

I replaced the starter on my 4-cylinder Frontier about 2006, used a CarQuest rebuilt unit (still working 125K miles later).

installing new battery cables wont hurt.

Ok guys. Replaced the starter. Still have the same whine issue as before I replaced it. The battery is less than a year old with new terminals. No there is no reason to jump start the truck because, as stated, the battery is fully charged(that's a redundant option). Just to reiterate, when I turn the ignition key, I hear a whine noise, instead of what should be the solenoid actuating the starter motor gear that turns the flywheel, then starts the motor. Apparently I am not getting enough voltage to the solenoid that actuates the starter gear. I have had a suggestion by my father that has said it is a grounding issue but I brought up the idea of it being a relay issue as they are also OEM as well. Having that said, I swapped relays and it didn't change anything so I am going to mess around with the ground wire that is directly bolted on the starter and see if that changes anything. If that doesn't, I'll replace the relay and go from there.

you can try bypassing the relay and see if it gets better. See post 12 in link below:

Not to be a jerk or sound too much like a nerd but cold weather generally equals less wire resistance. Was a major part of a class and what I end up dealing with every day. Makes a big difference what the temp of the room is when measuring values of resistors under 0.01 Ohms.

replace the start relay. that is the first thing nissan says to do after check cables, terminals and battery voltage.

When you put a NEW starter on, it came with a new solenoid.

I mean, you didn't put the old solenoid onto the new starter. Did you?

I have had the battery cables go to crud inside the insulated part. They looked OK on the ends, but inside they lost resistance. You could try bypassing the battery cables by completing the circuit with jumper cables. If the truck cranks fine with the jumper cables going from your battery to the starter, then it's time for new battery cables on your truck.

Nerd ! LOL

I stand corrected, but the cold weather can effect the battery especially if the battery is getting old and a battery that is smaller will have a harder time turning the starter over.
