good day Sir, try to check the ignition coil i hope this will help you.

you hit the nail on the head ,cold and silicone chips ,they do not like the cold weather they can be temperamental to say the least ,as for finding the faulty component you will need an identical car that works ok ,then when yours will not start try swopping bits till you hit the one causing the problem.or sell it for a nice manual diesel version,

good day Sir try to check the spark plugs and cables and ignition coil i hope this tips will help you.

Your problem is definately not a relay. It sounds as if the starter contact in your ignition switch is bad. The solution is to replace the ignition switch.

possibly. have you changed all your filters? check air filter and throttle body. may be ruined from the water. the throttle body can be cleaned with a fuel injection spray. does your check engine light come on?

there is no dist cap on this car it has coil overs as we call them hope this helps
