Hey, I have a 88 XJ and it wont start when it is cold out, under 30. but when it is warmer i have no problem. I can crank and crank but it wont even try to fire. My fuel pump was recently replaced along with cap, wires, and plugs. I dont know where to start. Any info would be much appreciated ty ty

 

I'd start with the tps (throttle position sensor) and cps (crankshaft AND camshaft position sensor)
