2000 jeep grand Cherokee Laredo auto trans, 4 x 4, stock security system

Been running perfect years...
Got in a accident about 6 months ago. pushed front passenger side fender in about 4 inches. (where all the fuses/relays/wiring harnesses are. I used *** a long to pull it out. Jeep ran fine after that.

2 weeks, it was hard to start, like it had an almost dead battery. Been working fine since...

then a couple days ago, it did the same thing. except it won't crank over at all... No clicks like a bad starter/solenoid. No nothing.

When I turn the car on I don't hear the fuel pump turn on. I pulled out the fuel pump relay and when I pull it out and put it back in I can hear the relay working.

All the dash lights come on when I turn the car to the on position.. The battery is fully charged and load tested. All positive and negative connections are good and corrosion free.

It has the stock jeep security system. I am able to lock and unlock the doors and hit the panic button.

Just for the hell of it, I changed the stater relay and the ignition switch.

I pulled out the fuse/relay panel ( coolant tank, battery, and the battery holder)under hood on passenger side just to make sure no wires got ripped in accident

 

Sounds like the usual crank sensor has failed you. It's a common problem. The sensor is on the top of the transmission bell housing. Top left if you're in the driver seat

 

But it should crank and not start right....

I'm not getting any cranking at all

 

Yeah, check the battery cable that goes to the starter. It may be loose in the cable clamp at the battery. Also check the wire that goes to the starter solenoid for power when you try to crank it. Also, there is a starter relay in the PDC (fuse/relay box under the hood)

 

All positive and negative connecions are good, tight and clean.

Starter solenoid wire gets no power. The starter relay is good. Not sure about what ports should get power or whatever...

 

Have you tried starting it in neutral? Either that or press forward on the shifter when it's park. We're trying to eliminate the NSS as a problem.

 

yes, and wiggleing it back and fourth a million times while trying to start.
