1987 280GE. No fuel to injectors.
Slowing down for roundabout on Good Friday, low mileage, excellent condition (thanks Bill) replacement engine cut out completely and wouldn't restart. No tools aboard as not off-roading and not going far (when will I learn!) so had to call RAC who discovered fuel to distribution head but nothing getting to any injectors or from return pipe. "not seen this particular injection unit before, Sir" so had to be towed 2 miles to local garage - after Victor Meldrew moment when told "you'll have to wait for Recovery vehicle as we can't tow it because might damage centre diff" !!!
Anyone got any ideas?? I'd like to be able to confirm or deny garage diagnosis due later this week cos they're bound to pick most expensive solution!
Bill - any sign of the new rear springs??

if you've got it from bill,well i guess your in luck :!:
he gives a lifetime warranty :) i am sure he will help you out with this dilema :wink:
by the way, which G did you buy off him :?:
good luck.
Check fuel pump by directly bridging contacts at the fuel pump relay, if the pump buzzes it could be working, you still need to check if transfers adequate fuel under pressure. I could explain but it will need fuel pressure testing equipment, one can improvise but safety is at risk, therefore, I will refrain in that explaination, do not want to be sued.
Or the fuel pump relay has packed up, the very unit you remove to bridge the fuel pump.
Has the fuel filter been replaced?
Just a few obvious pointers, get in touch when you know more.
Regards,
There is a filter on the inlet of the distributor. That could have blocked.
Or have you pushed down the flap whilst operating the fuel pump. That will increase the amount of fuel to the injectors. It is a fairly basic system. Does the fuel pump sound smooth when running. Disconnect the fuel pipe entering the distributor (where the filter is) and operate the pump. Fuel should come out so put a flexible hose on it and direct it to a can. That will verify whether the pump is working
I had the same problem. changed the fuel meter, pump and for good measure new injectors. All fine now. There is a company in London who can fix this fuel meters. Let me know if you need their number.
Turned out to be faulty accumulator. Seems that fuel was being pumped up to distribution unit but not at sufficient pressure to work the injection system. Confusing / difficult to diagnose if you're not familiar with mechanical fuel injection!

Hi Huss55!
Better make myself clearer before I have Bill chasing me!
I didn't buy my truck from him but he did help me source a new engine for it a year or two ago - well out of any reasonable warranty period - and my thanks to him in the post were genuine not sarcastic!! Actually I can't even remember whether the new engine included the injection unit or whether that was transferred off the original motor.
Hi Pistonhead!
Fuel is being pumped up to the injection unit. Don't know if the pressure is sufficient but RAC man seemed satisfied that the problem must lie in the distribution head (if that's what it's called). I've had numerous fuel pump problems / replacements mostly due to corrosion from mud etc. And this pump isn't very old. If fuel wasn't arriving at the injection unit under enough pressure, would nothing at all go to the injectors??
