Ok, I bought this jeep about a month ago and drove it about 2200 miles so far. On occassion I put the key in the ignition and turn it on but it will not crank just silence. When trouble shooting this I replaced the Starter, Regulator and nothing still silence. I then got a notion to just turn the key over and over and after about 15 times I heard a click and it started. Since this time it has done this to me several times and I either turned the key over and over or I let it set for about 30 min. and it would start. The other night I started it and moved it 20 feet to my garage and it hasn't started since. I have replaced in troublshooting it, the Starter Relay, Iginition switch on the lower steering column and the key barrel switch. I have played with the NSS but have yet to replace it as I have shifted the auto tranny in every gear and tried to start it with nothing but silence. I am at my wits end.....

Any help would be appreciated.

When you turn the key to on do you get dash lights but it won't crank? First thing I would do is have the battery tested and/or replace it as well as clean the terminals, it could be as simple as that.

The NSS is a possible culprit as well, but don't replace it...they cost a small fortune. You can clean/rebuild it for next to nothing.

The battery is brand new 6 cell Napa Nascar battery, got a friend that sells them. Very Happy

As for the das lights, yes they come on and my guages get power.. specifically the Temp and Volt gauge some alive. When I turn the key to start the jeep the Temp gauge redlines and the Volt does nothing and the brake warning light and one other come on when I turn it all the way forward.

The NSS I read about before posting this piece. It sounds like a good last resort.... I did already play with the positioning and alignment per my chilton manual with no success. I will try to rebuild this item if there are no other best guess.

I would say just to be safe look at all wires, mechanical levers, starting at the steering wheel column and trace everything to the fuse box and to the firewall. I would start there to make sure no mice have been in there. Also check the fuses in the fuse box and make sure they have good snug connection, had one get hot over the years it melted it's self just a little loose, enough to make a connection when it felt like it rofl rofl

When you try to turn it over, does it at least click (or make a series of clicks). If it does, then the solenoid is engaging and you've got a power issue. If no click(s), then the starter solenoid is not engaging. Most of the time that points to the starter relay...but you've already replaced that. So you may have some power issues that are starving the starter and/or starter relay for power. Check the battery cables, the battery ground at the block and the power cable at the starter.

Also check to see if the starter mounting bolts are tight and torqued to spec (that's the ground for the starting system). Other less likely culprits could be stuff like rust in the starter solenoid piston, a loose connection nut at the solenoid or a bad/worn solenoid wire. Since it's a new starter it's not likely...but check to see if the starter is covered in oil (from a leaky filter mount or a sloppy filter change). The oil gets into the brushes and messes up the contacts.

given the year i'd consider replacing your cables that go from the battery to the starter - and the ground cables as well. there is a difference between getting power and getting good power to the starter. cleaning the connectors just won't cut it if the cables themselves have started breaking down just past the connectors.
