I have a 1984 380Sl, just purchased. Has less than 2000 miles on rebuilt engine ( engine done by repuditable shop..has all papers for up to $12,000 in repairs since 2003) 91,000 miles. Problem is I'm getting no electricity to fuel pump. I have changed relay, ICU, fuel pump. fuses Used test light and no electricity is getting to relay. I'm almost about to head to dealer, and help buy him a new Maybach. So HELP!! Any sugguestions on troubleshooting will be appreciated. Thanks
