Hi , I have a S-type that won't start been lying for 6 weeks now its just turning over and won't fire , there is fuel going to the fuel rails but when turning there is a lot of white smoke coming from the engine bay , it fired up for about 10 seconds but wouldn't rev and was not running on full cylinders 

 

anyone any idea what to check

Hi

Is it petrol or diesel

first of all make sure the battery fully charged, if not sure, put it on charge overnight first

if its petrol, remove the plugs and clean them, they could be fouled up

if it diesel, let it stand for a few hours, then put the ignition on and wait for the glowplugs light to go out, then switch the ignition off and then back on till the glow plug light goes out, let the glow plugs heat 3 times before attempting to crank the starter over and start it

cheers

Joe

HI Barry, and welcome to the club.

Joe had pointed you in the right direction.

If a diesel, a small shot of an suitable injector cleaner would do no hard, as it foes seem a fuel issue.

Regards,

Peter.
