Hello, about once every three weeks my 1990 740GL won't start after i use it and the motor is at operating conditions. If i let it sit for 30 min. she starts right up. This only happens like once every three weeks. I really appreciate any help on this matter!

Thanks,
Scott

 

FI relay would be a start...

 

Thank you! I was thinking that also

 

You mean the fuel pump relay right?

 

Is the fuel pump relay the white box shaped thing behind the ash tray?
