I have found one relay(white), I assume for the LH jetronic system, on the passenger footwell wall/firewall ,but where is the "main" fuel pump relay?
My 1990 240 was stalling and not starting hot or after a rain, I found(after numerous assumptions) a poor connection at the fuel pump.in other words:
The car would not start until I wiggled the wires. Yes I replaced the LH jetronic relay ($14groton) and cleaned the 25 amp fuse near the battery and replaced the fuel filter and check the air mass meter/MAF(mass airFlow sensor) and cleaned the ground points.
The self diagonstics flashes 1-1-1 code. I drive the car only 20 miles a week.(it ran better with more miles per day) It has 160,150 miles. I've looked and looked but can not see the main fuel relay.the Bentley book has an ambiguous picture of the location. thanks Phil
