Customer Question

1974 Series 3 Jaguar E Type, has a cold staing problem. It cranks and cranks, coughs and splutters with increasing frequency, and finally catches after about 5 minutes of cranking.
Once up an running, engine runs sweetly with plenty of power.
Fuel supply and choke operation all checked and seem OK.
Any suggestions?

if you haven't already then check the resistance of the spark plug leads ( 13-15Kohm / metre) and replace if any doubt or high resistance - Also replace the spark plugs if any of them fail this checklist:

You can also try spraying some water on the coil with the engine running. It is possible the coil is faulty and causing the issue. If you see sparks arcing with the water, then replace the coil.

I'd also measure fuel pressure before the carbs as you should have 3-4psi
