No start but has power
My son has a 1996 Jeep Cherokee that has just deleveloped a starting problem.
When he goes to start it, all accessories lights, gauges, fuel pump, etc come on, but when I turn the key to crank, nothing at all happens.
There is a click that comes from the engine compartment when I turn it to crank but nothing else.
Tests done so far:
Wont jump Start
Bypassed the NSS no start.
Battery has normal voltages and power.
The solenoids getting power.
The starter relay is good.
Crossing the terminals on the celoniod with the key in the ignition does start the motor.
So battery is good, starter motor is good, starter relay is good, celonoid is also good.
What else could it be?
TIA

Was battery tested with a multi meter or was it load tested? A bad battery can still show full voltage, but not have the amperage available under load. Check ALL grounds.

I tried the b+c with a paper clip, it didn't start. I replaced the starter, and still no start I tried the jump again this time twisting a piece of wire and it started. I would try it again cause its so common for the n.s.s to go bad.

Well tried the bypass again, still no start, and I an defiantly using B+C in the correct lug, followed the cable up from the transmission.
Anyhow to get him going, I ran a 12 awg wire from the small post on the solenoid and a 12 awg wire from the + post of the battery to a momentum starter switch, used a 30 amp inline fuse in the + wire. The Jeep starts every time first time now.
Could the NSS switch still be faulty even though bypassing it did not work (For me) it was also interesting to note that we do now not have reverse lights and the Jeep will not start in neutral.
If the NSS switch is the likely culprit I will take it off next weekend and clean it.

not trying to act like a smart *** but are you doing the jump to the harness at the engine bay or are you jumping the end that goes to the trans. I really have ran into like 50-60 of these at the old shop.

I bought my n.s.s. from a ebay site, I used the write up on here to clean the n.s.s. it did work but after a month or two I had to put it in neutral to get it to start. I'm not saying that it won't work, but for me I think mine was well worn out.
