2.5 Petrol 2002 X-type not starting after 1 month's storage

[Sean 2.5]

Hi,
New member here!  My 2002 x-type 2.5 petrol, purchased new and with only 80k mi, is not starting.  The car was in storage on a battery tender for the past month.  Initially after taking it out of storage the car started and ran for ~30mins but after shutting it off, it would not restart.
- Battery, alternator, & starter are all good (confirmed with local shop)
- No error codes

It feels like an ECM issue, any suggestions?
Best,
Sean

Welcome aboard! Try the CKP - Crank Position Sensor - these won't give a fault code but will cause a non-start. They also usually fail suddenly. Had that happen on my S Type a couple of years back, fitted a new one on a hunch and fired up immediately.

Not sure where in the world you are but give Rock Auto a try in the USA, it's a fiddly job but doesn't take too long.

Dave - Thanks for the suggestion, any idea where the CKP is located on the 2.5?   Thanks, Sean (Northern NJ)

It's normally just behind the crankshaft pulley on the front of the engine. It's secured by a cap screw (5mm key as i recall, it's a Metric fastener so don't try a 3/16" Allen key as it will round out) and is awkward to get at but possible laying under a securely supported car. Patience is needed and a smear of silicone grease on the new "O" ring on the new sensor to help it slide in nicely.

If the plug is dodgy as they deteriorate with age, you may want to go for what's known as a service kit that comes with a new plug with fly leads and you cut and connect them to the loom further back from the deteriorated area around the plug. Here are a few choices from Rock Auto :

Good luck and hopefully that is the cause of your non-start.
