85 240 stalling at random

My lady's 85 244 (B230F, LH-Jetronic) yesterday decided to start stalling on her. In a 3-block trip it stalled 6 times. In each case it seemed to stall when accelerating up to city speeds. The stall isn't preceded by any rough running or bucking: it just quits. The engine starts up again willingly after a stall, and while running it is as smooth as it ever is.

I'm aware of the fragile nature of the engine wiring harness, and that will be my first path of investigation, but has anyone else come across this problem before and found a different cause?

Thanks, Lyle

Is the tank low when this happens? If so it could be the in-tank pump and/or the main fuel filter. Another possible cause is the fuel pump relay. You can open it up and look for broken solder joints and repair them or buy a new one ($42-45)

She filled up the tank after the first couple of stalls. It only took 24 litres, meaning that the tank was over half-full initially. It has since stalled several times with a full tank. I replaced the main fuel filter last year, so I don't think that's it either. The in-tank pump is a possibility, but I'd prefer to leave that as a last resort, given the difficulty of removing the sender/pump unit. I'll check the pump relay. Thanks.

You can get a relay here for a bit less. I have purchased from them without problems. Shipping is free if your order is for more than $50US. They ship to Canada.

$42 for a fuel pump relay? FCPGroton has the white ones for $14 and the green ones for $25. You must be talking dealer prices, right?

"Ding!!" When you mentioned the fuse I suddenly remembered reading about this on the SwedishBricks discussion list. Turns out that was the culprit: the classic corroded fuse holder. I've cleaned it up now and we're good to go. Maybe I'll look into ipd's waterproof fuse holder...

Thanks again, Lyle

Yup, I'm aware of ipd's price inflation, so I took a boo at at Pico of Canada's Web site

and ordered the the Weather Resistant Fuse Holder (Pico PN 951, in case anyone's interested) from the local parts store. Cost is ~$4.50 Cdn. From the photo, it appears to be the identical unit in the ipd assembly.

Cheers, Lyle

My 85 240 started out with random stalling or engine sputtering. Making a long story short, after it would no longer start, I found that the rotor has a resistor in it and this resistor finally crumbled - causing it to be open. Jeremy
