Starting Issue and Relays
Discussion
Hi Guys
I have just picked up my wedge 1987 350i I won on ebay, car seems fine for what I paid.
The seller told me of a issue with the SM Module and that he had jumpered the fuel pump relay as the SM Module was faulty and would not switch it on.
So I purchased a new SM Module fitted it and removed the jumper wire, now the car will start for 5 second and cut out, I can also hear one of the relays chattering.
So I think I have now got back to the original fault, im sure it will be easy to find if I could find out which relay is for what, my glove box does not have a diagram on it, the maintence guid has a relay location guide but is totally different to mine.
Does anyone have a idea what relay is for what ? on the diagrams on the net there is only 6x 3 relays mine has 7x 3 relays.
Any help appreciated
John

I don't recognise your symptoms but I'm sure the answer will be here somewhere

You may find this enhanced circuit diagram of the flapper Efi system helps with the rest of the information on my site?
As far as identifying your main and pump relay locations, they should be adjacent to the SM. I am not familiar with your relay layout, but the circuit cable colours will help, as will an ops manual, methinks.
The flapper Efi system suffers generally from connector problems, so cleaning contacts and re-seating the two relays in their bases can also help, likewise the AFM and ECU connectors.

Car all sorted, turned out previous owner had made a mistake and put some of the relays in the wrong place, the SM was in the Fuel pump position and the Fuel Pump and ECU relays where round the wrong !
I checked the ecu on pin 10 and found no volts on it !
Now starts and runs well, just need to sort slight hesitation out, think its the throttle pot.
