car starts and will not turn on again once off at operating temp.
i have an 1984 Jaguar that i have been using as my daily driver, and recently i have had an issue with it, I was running some errands, and i was running around town, and i tried to turn the car on after using it at about an hour, and it wouldn't turn on. the car is at operating temperature, and once i wait for it to cool down it starts up again. the car doesn't shut off. This only happens when i turn the key. can someone help me out? thanks.

Does it crank when you try a hot restart?

Not sure if I understand what your saying. Alan's question is pertinent as a first step. Cranks-but-won't-start when hot is often an ignition module...but could be many things. Cheers DD |
I'm sorry i took long to respond, and sorry for the ambiguous statement. i must not have been paying attention to what i was typing. the car cranks yes, what i meant to say is the car briefly fires, and then dies when its warmed up. I replaced the ignition module as i have heard about this, but now i am not sure how to proceed.

Check to see if you have fuel pressure during restart after a hot-soak. No fuel pressure indicates a leak and loss of 'rest pressure' usually at the fuel pump check valve, cold-start injector or one of the fuel injectors.

will try it out this weekend and will report back

sorry i haven't been able to post on the forums in regard to this issue. We've gone through some strange weather down here. We went through four seasons in one week, and a wet season the week before.
i found that one of the hoses from the fuel rail was leaking fuel after i gave it a gentle tug. |
Oh wow, good thing you caught that. These engines have been known to spontaneously combust when the rubber fuel hoses on the rail go bad!
