Ok so here is a little run down on my jeep. I just purchased a used motor from an engine shop, just finished installing the motor, now no start. When i turn the key nothing happens. i can hear a faint click but nothing, i know the starter is still good and the solenoid i have tested them both. the starter engages when you jump it and the jeep fired right up. I'm leaning towards the NSS but when i turn the key on and put it in reverse the reverse lights come on. Sorry for the life story lol.

 

what year and engin, did you do the work? give us some details.

 

94/ 4.0, yes i did the work just an easy pull out the old put in the new

 

Sounds like the battery to me

 

thanks thats what i was thinkin to

 

check it put a jump box on it. simple test

 

well i tried jumpin with my truck yesterday and it didnt do anything

 

Ok sorry to state the obvious here but are you sure you hooked the ground cable back up to the block?

 

are there more than two? i have the one on the dipstick and the one from block to firewall..... and i checked all the fuses, they are all good.

 

I would say double check the fuses and all your connections. It kindof sounds like a connection issue. Make sure you battery connections are tight as well. Chances are something didn't get hooked up or tightened down during the swap.

 

my main question is could it be the NSS? Im not gettin an engine code, and the reverse lights still light up in reverse

 

could be. Did you try and start it in neutral instead of park and wiggle the lever around?

 

yes i did...... i tried starting it in every gear, and tried wiggling the shifter in each position, and still nothing.

 

Still could be the NSS. I would start troubleshooting and take some voltage readings. You gave to see where you have power and where you don't. Make sure you battery is full charged and start measuring wire voltage.

 

okay thanks for all the help. Im gonna go get my meter and start checkin where the power is stoppin
