Car wont start, Merc/Benz C240 2001

Change gas cap.

You have a check light on--you have codes

Fuel gauge is not accurate

Need a different shop that has a data base,
so they can use reference material for your
vehicle & resolve

Did you go for a road test with the mechanic &
did they have a scanner hooked to the DLC
under the dash,if not you wasted your time with
them

is the check engine light on? and if so what are the codes? when was the last tune up?

Mine was doing the same thing. I Change the fuel pump and I was up and running again. Then it died again w/ the same symptoms. Thought it couldn't be the fuel pump, it was new...New, but defective. Good Luck

Check this link out.Here's how to replace,if this doesn't work,take back for refund..

If it is a 3.8 engine change the crank sensor,they go bad on the 3.8 engines.

Hi, this really depends on its service history.

The following are the recommended service intervals on the Merc S500:

Note: operate A/C at least once per week, to maintain lubrication.

Underhood & Undervehicle

Every 3,000 miles - Replace engine oil & oil filter. Clean battery terminals. Adjust drive belt. Check power steering fluid. Check steering & CV BOOTS for wear and replace if necessary. Lubricate front end suspension.

Every 6,000 miles - Check transmission fluid condition and level. Check brake pads and caliper components - replace if necessary. Lubricate driveshaft U-joints. Rotate tires. Lubricate wiper arm linkage and pivots.

Every 12,000 miles - Adjust engine valve clearance. Replace distributor cap & rotor. Drain and replace engine Coolant. Replace Air Filter element. Replace Fuel Filter. Replace wiper blades.

Every 24,000 miles - Replace Drive Belt. Replace A/C Compressor Drive Belt. ** Change auto transmission fluid & trans filter (this is critical and must be adhered to) - preferrably do a trans flush at same time. Replace drive AXLE fluid.

Every 36,000 miles - Replace HT leads.

Every 2 years - Replace brake fluid (also clutch fluid if applicable). Replace power steering fluid.


** If you intend to keep this vehicle long term, then consider changing the trans fluid & filter every 20,000 miles. This is the secret to automatic transmission longevity.

Listen for the fuel pumps to come on when you turn the car to on (not start) if you hear them its a spark issue normally. Suggest checking/replacing coil packs, engine wiring harnesses for degradation because of biodegradable wiring insulation.

What was the code? You need to check for spark at the plugs and fuel pressure at the fuel rail.

Check the fuel pump, the fuel filter, and the return lines to the fuel tank. Any one of these things could cause a zero pressure condition in the fuel system.
