My xj40 didn't start this morning. She is turning over but won't start.. It has been running fine and I drove it last night. It was cold outside last night like colder than normal. Could the battery being slightly drained keep it from starting? What's the likely cause? Fuel wise I can hear the fuel pump priming. My guess is electrical problem. Please help me
:'(

 

I would say battery first at such problems , have it checked out or jump start but make sure all the connections are right with that because it would cause some damage if you reverse the connections

Yes, I would put it on the charger and see if it starts with a full charge. Otherwise you must begin the hunt between fuel and spark. The Crankshaft Position Sensor is known to fail on these cars which would cause a non-start situation without anything on the VCM.

Do you have any codes on the VCM?

Also, did you ever get your transmission problem figured out, or have you been 'limping' around town?!

Cheers,
Scott

 

Ok... Vcm says.... fuse 2.... Pad.... Fail.... What does fail mean? It has always said fuse 2 and pad....

 

Either driver side or passenger side is Fuse 2 . I don't remember which is which right now sorry . You need to remove the fuse box covers to gain access the fuses , one of the fuses is shot from what I see .

 

fuse 2 is drivers side fuse box. it's located close to your left knee. open up and check fuses. PAD means brake pad wear.

 

here's the fuse diagram from 1994 xj40, it might help you locate problem
How many fuse boxes does the 1994 Jaguar xj6 have and their - JustAnswer

 

I suspect a relay gone bad since you said vcm has always said fuse 2 ? check light blue hella relays they go bad a lot

 

I'm sure that I'm totally off base, but when my 1990 wouldn't start, it turned out to be as simple as the rotor in the distributor. The mechanic told me it was a common problem.

 

Fuse 2 is just my seat belt fuse and it's pulled out on purpose. Fail only came up once on Vcm and it doesn't come up any more. I'm going to charge battery today and see if that fixes problem... If not I'll start checking spark

 

Scott I'm still limping around.

 

Jumped her with my friends diesel. Started right up. In all my years I've never seen a car have enough power to turn over but not enough to fire

 

It's a Jag....

Good that you got it started.

PAD can also mean an expiring brake sphere. Easy enough to detect, if you can hear it charging every time you press the brake pedal. Sounds a bit like a football with a puncture that sighs when you stand on it, and you will see the Red warning light flash on when braking.

Not the cheapest part on the planet, but a whole lot cheaper than a new pump.

 

Had this syndrome one very cold UK winter with a Rover 75 (-14C at night and most of the day). When the AA man called, he managed to start it straightaway, but he did say there was "a knack in it". Anyway, I had battery tested which said it was failing, replaced it and no more trouble.
