Hello!
Nice looking forum!
I just bought a 1989 300SEL yesterday
WDBCA25D2KA446759
Had seemingly no issues yesterday morning... so I bought it from granny down the block .... took it for smog, and had a bit of trouble starting it up afterwards... and since. tried this morning again and got it going, held the ignition till it stopped making tone, repeated... then full turn and fired with gas pedal.
when it does start coughing i need to give it some pedal. jumps right up.
needs pedal nearly every time.
there is a whining-hissing- noise somewhat like an arcing-light-switch sound that is coming from very near the fuel pump..... its prominent- if it were your lightswitch you'd call the electrician.
im nearly sure its fuel delivery related for my start up issues.
once running its really nice.... though this morning I just noticed that it seems to be searching for RPM..... when it starts at 1000, and even after it drops to 650... seems like varying between 75 and 100 rpms. yesterday morning while watching the engine run I noticed that cylinder 3 seems to be arcing from the plug to the cyl head.... so im going to be changing plugs and wires and will see how it goes.
main thing is the issue starting- i don't want to be taxing my battery and starter every time I need to go somewhere.
Any input or advice helps,
Thanks for having me.
