1989 420SEL STARTING ISSUE
Hi All,
On my 89 420SEL when starting it takes a bit to catch(3-5 seconds) than low rpm's and followed by a stall. On second crank it starts runs rough and than smooths out. This is not a constant, but it has been happening more often than not.
It has 52K and has had cap, rotor, plugs, and wires within the past 18 months. All fluids(brake, transmission, rear, steering, radiator)have been changed also. My first thought was fuel filter, followed by fuel pump relay.
How do I go about making a better diagnosis.
Thanks
Bruce
