Hello list,

I have an '89 300ce with 215k miles and still going strong.

Just recently when I turn the key to start it, it does not start the first time, but it always starts the second time. Also any time starting again after starting 1st time its OK.

This model "CE" has twin fuel pumps, does anybody know if it has the check valve installed like the 300e.

I suspect fuel pressure. Because any time there after its OK.

What keeps the pressure up in the fuel lines, is it the accumulator or the check valve. Can the fuel pumps bleed down?

I have checked the fuel regulator for pressure and its OK. However, I havn't checked it for overnight pressure

Would i need to replace or check the Fuel Accumulator for pressure.

Any help would be appreciated.

Brian
