Re: Xj won't start when cold
Before you go dropping a load of cash on a new ECU, have you tried a different battery?
Re: Xj won't start when cold
Start with battery. Get a fresh one with clean terminals. Cold weather affects batteries before anything else.
After battery check spark level from coil/icm and connectivity. These have always been my biggest problems from cold weather.

Re: XJ won't start when cold
It's a brand new interstate. An it won't be the coil because it's spark an fuel at the same time. If I park in The garage for the night I crank it once. Pop the hood I head the squeak noise from the starter I shut the hood an it runs fine. Like I said threw out the day it's fine doesn't stall or anything it runs fine. Just after sitting for a while. I'll check Craigslist an see what a used ecu goes for.
