Electrical problem
1987 Jaguar XJS V12 Two Wheel Drive Automatic 140000 miles

Hi,


My XJS V12 is not starting, I changed the coil and ignition amplifier, the battery and plugs are recent.

When cranking the engine it seems to start but nothing.

When testing the coil disconnecting the lead with the distributor and putting it to a métal bar on the engine and cranking ,i get a yéllow spark but not bright nor blue

What could it be?

After cranking the plugs are full of benzin so I assume the fuel pump or injectors are not faulty.

I removed the distributor cap to see the rotor arm condition but noticed nothing.

How to diagnose the failure of the distributor itself or components?
