after all that work ,replacement of the fuel pump relay and OVP would be the only items left. i replaced these on my 300se and all is well now. the opv and fuel relay had cold solder joints ,temp dependent.

I guess I will try the fuel pump relay now. What is the OVP?

Thanks,

Erika

OVP = overvoltage protection relay. Sits right next to the fuel pump relay.

Ahh thank you, mine is missing one of those 10A fuses in it. Could that be my issue? Can I pick them up at Napa?

thanks again,
