96 jaguar 4.0 6 cylinder wont start from cold..but

Google will show you pictures of what to look for but I would suggest trying terraclean. They offer a specific clean for the egr without removing it and can check the system operates correctly so it won't simply clog up again during to a fault in the system.

in the trunk fuse box

Repair your vehicle right away. Just click on the link I attached 1995 jaguar x300

i presume this is a x300 series, you should hear a click from the gear selector area when you press the brake pedal with the ignition on, if not the park release soleniod is not working, the common cause of this is the brake pedal switch faulty, you can manualy release it by removing the little star shaped plug near the gear lever and inserting a small object like a screwdriver or your key, then select N and start engine,

sounds like your engine is the old v8 with nicosyl coated cylinders they wear badly due to high sulphur content in fuel which eats away at the cylinder walls they lose compression and swithed off or stalled when cold and it wont restart. later engines had cast iron liners check your engine no., to see if thats your problem. have changed up to 4 engines a week a few years ago because of this issue.

crank relay on the front pulley or ignition module under the coil ,it has to one or the other

That code is for Engine control module engine immobilization input circuit malfunction. Ignition coil is ok.

my 1991 Jaguar XJ6 Sovereign will not start...just get alarm..what do i do?

the fuild is the same type used in a gm prodation model . has the torque converter been drained if so start with about 10 qaurts start the vech cycle it through the gears and check add as need

If the locks are working whilst you are driving then more and likely it is the actual door lock assy that is bad. the solenoid go bad and can cause erratic operation. But unfortunately they are only available with the whole door lock/latch assy.
I would disconnect the drivers and see if the problem still exists.
