Hello. I have an F reg MB230TE. I have owned it for approx 12 years and it has been a good reliable car. Recently I have had problems starting. She wants to go but then it just turns over. The AA man diagnosed it was the feed to the fuel pump. My local repair mechanic has determined that the relay seems ok and the pump works but I will replace it as the threaded section has been broken (possibly by the AA man. It strikes me that from what I can see the cable is mainly shrouded along it's length so it would seem odd if there is a break. The mechanic ran a feed from the relay to the pump direct and the car started. I have read the the relay can sometimes be the fault? What can anyone suggest. I don't want to spend large amounts on a new relay just to eliminate this possibility. Does the connection from the relay pass to the pump via a fuse? The fuse diagram doesn't show a fuel pump fuse??? I wondered if someone might advise. I'm not a mechanic and I don't understand electrics. Derek

Hi. If Yr sure when AA man ran sepperate supply to pump the car ran?
Then Yr wiring or relay , or power too is suspect. Bein honest most likely culprit is relay ot whatever switches it . (power from ignition)? Suspect AA man ran supply to pump from supply to relay.

I'm looking at this thread because I was genuinely curious what a Derek Holder was.

With your model car the fuel pump relay could be in 1 of 2 places, in the cabin of the car, under the passenger side kick panel, remove the under dash panel. with panel removed, on the side kick panel there should be several relays there should be rectangle black box (may have the word KICKDOWN written on the top. remove this relay, look at bottom of relay there will be numbers for each metal pin , find pins 87 & 30, now go get fused jumper wire, put one end of the wire in the female connector for pin 87, then put the other end of jumper wire in female connector pin 30, the fuel pump should run, you do not need the ignition key. 2nd place is under the hood by fuse box\hood hinge area there is a plastic cover, remove cover, tall black relay should be under plastic cover! depending on VIN # XXXXX your car. if relay is not located in 1 of these places please get back to me with VIN # XXXXX your dads car & I will find the relay & get back to you!! good luck get back to me when you can glad to help!
