(battery power was good and fuel was enought. next day same result. this car is an oldtimer and i had no problems at all like this or others. do you have any idea what the reason is

Thank you for your reply

There are a number of reasons that may prevent it from starting. None of which I can diagnose from here based on your description. I am guessing you don’t work on the car your self, right? My best suggestion is to have it towed to a good local mechanic and let them diagnose the problem.

If you do work on the car yourself, check for spark. Then squirt a little starting fluid into the intake and see if it runs for just a second or 2 and report back.

If you’re trying to run the car with gas that was sitting in the tank for six months, there is a good chance the gas is now rotten. If this is the case, gas tank will need to be drained and refilled. Definitely have it towed to a mechanic.

Trank You for the quick reply of my email. Yes l am able to do a lot of Standard Repairs on Cars als a Kind of Hobby. But this car has a lot of components which are very complex and without Plans and Drawings it is nearly impossible to work on this Engine.
