Jaguar 2001 S type Most of the time the car will start and run find. When you drive the car and turn the car off, at times it will not restart. I will turn the ignition to start the car for about 3 to 4 seconds and then try again. At times it will start after several times. I never smell and gas. Any advice from Jag owners that may have experianced the same problem.

Neutral safety switch needs adjustment.

this indicates a problem with the variable camshaft timing and possibly requires reprogramming PCM module
assume the engine warning light is on? does the engine run normal?

fuel starvation or your auto choke isnt engaging pump the gas pedel a few times when starting get some fuel through the jets, have you been running the car on low fuel this brings up the sludge from the bottom of the tank and blocks the jets try some jet cleaner in your tank when its running this will clean out your jets and give you better acceleration and fuel economy

As most timing chains, when they start to get noisy, that is usually when they start to stretch beyond there limits, refer to owners/service manual for any periodic maintenance.

have you checked your rotar cap,or your timing belt?

Water vapor coming out of the exhaust at initial start-up is normal; that is condensation that collects when the engine is not running. White smoke at start-up depends on a couple of things. Tell me, where do you live? When the weather is very cold, all engines will emit steam (white smoke) when they are first running; this stops after the engine has been running a while and is warm.

In short, if this is only happening at first start of the morning and goes away over time, there is nothing wrong.

If, however, the "white smoke" continues and never stops, you may have a blown head gasket.

Timing Chain... thanks goodness!

i have a 2001 s type 3.0 l it has a timing chain not a belt are you talking about the aux drive belt which drives the alternator ,coolant pump,aircon,steering pump

Hi m just drain refill  turn the heater to full hot run engine or drive for a couple of miles let it cool and top up   never had any problums with a s type      D

it apears to have been a faulty fuel pump ie no pressure at test point tapped fuel tank with small mallet fired up straight away.new fuel pump on its way. thanks
