I parked my SLK for three years. Today I decided to start it. Put in new battery and it cranked fine, but will not start. Any ideas?

Thanks in advance.

 

fuel line may be clogged?

 

Welcome to the forum.

Modern fuels have addititives called oxygenates required by federal and state governments to reduce polutants. This is not your father's fuel, this new fuel (previous 10+ years) turns yellow after a few weeks and after a few months develops into a varnish like substance called gum and forms gum solids. This coats your fuel systemand clogs very fine openings, not fuel lines but fuel injectors will get clogged and your car won't run as well with the bad fuel.So the proper thing to do is empty the gas tank, fuel lines. Have the injectors cleaned out or replaced and fill up with fresh fuel and start the car. Next time, consider using fuel stabilizer like Sta-Bil but remember, you have to keep adding it to keep the fuel from gumming up. Also, consider that gasoline is toxic and considered hazerdous waste and should be disposed off in accordance to your local laws or you could be fined severely.

Also, other things happen,fuel pump can dry up insideso check your fuel pressure at the fuel rail, should be about 50 psi.

 

Thank you both for your fast responses. I will check the fuel supply this weekend.

 

One more thing, Is it hard to take out the fuel injectors? How would I test them once they are out? Is this something that a home mechanic can do themselves or do I need to take the injectors to a shop for them to be cleaned out?

Thanks again.

 

bump, still need to know how to take out and test fuel injectors.

Thank you.
