Code P1586 on a jaguar s type?

Answer 1

Code P1586 is for the electronic throttle. It's either a faulty throtle body or a wiring problem between the PCM and throttle. You may also want to check the relays in the under hood fuse box. Try tapping on the relays as I have seen problems in the connections at that fuse box causing the no start and that code. If that checks out good then the engine may be flooded from sitting. It may be a fuel pump or crank sensor but you should try the clear flood method. Try holding your foot on the gas and cranking the engine. You may want to install a jumper on the battery as this will draw down the battery fairly quickly. Also take a break after 20 seconds of cranking to cool down the starter. You may have to remove the spark p[lgs to clean or replace them. Once removed spray some WD 40 down into the cylinders to build back compression. To check for fuel pressure you can push down on the shrader valve on the passenger side of the rail under the engine cover while cranking. Just be carefull because if there is pressure fuel will squirt out. You can also try to rent a pressure gauge from your local parts store and hook it up to that valve. To check for spark remove a coil and spark plug. Install the coil to the plug and with the coil plugged in and the spark plug touching the metal throttle housing see if there's spark. Or lastly the timing chains may have broken from damaged tensioner which will also cause the no start. If the engine was running smoothly before this then I do not think it's the problem but it is a possibility.
