hey there i got a 2001 xj that wont fire up not getting gas or spark i changed the cps still nothing redid all the grounds still nothing im going crazy im thinking maybe its the ecu but i want to know what else to look at before i go and put more money into my jeep thanks

 

Try cleaning your NSS and see what happens. My 98 XJ did the samething. Another thing is is does your reverse lights work? If they dont then I would definitely look into cleaning or replacing your NSS. 1aauto.com has a very cheap one for around $60.

 

If its the NSS, when you turn the key it will click but wont try to start or anything

 

maybe ASD. check fuses both in cab and under hood too.

 

hey she cranks over but no start n the lights work im at a full loss here man

 

i did that too man im going crazy with this thing

 

saw you said it wasn't getting any fuel, maybe fuel pump?

 

Found this thread maybe it can help ya
