cooperson Posted December 11, 2014 Share Posted December 11, 2014 Hope somebody can help After cutting out and not able to restart ( it cranks fine)no diesel at injectors, i thought it has to be stop solenoid so removed security block and wired it direct still no go, so removed solenoid and took out plunger and refitted it and guess what, still no diesel to injectors, so to recap I have fuel out of filter when cranked, at injection pump banjo when cranked also with stop solenoid removed diesel pumps out ok and at bleed screw at centre of the 4 injector pipes at back of pump,so how come I get diesel to this point but not out to injectors? I'm starting to think something expensive has happened to pump, any ideas? Quote Link to comment Share on other sites More sharing options...
GW8IZR Posted December 11, 2014 Share Posted December 11, 2014 Might be worth pulling the timing cover off the injection pump pulley and see if that's going round. Quote Link to comment Share on other sites More sharing options...
cooperson Posted December 12, 2014 Author Share Posted December 12, 2014 Thanks, good idea, i hadn't realised there was a hole behind compressor belt adjuster anyway just done that and it's turning ok Quote Link to comment Share on other sites More sharing options...
alland Posted December 14, 2014 Share Posted December 14, 2014 hi have a look at the fuel pump on the side of the block 2 13 mil bolts if i remember and see whats happening there sometimes they wear or the finger snaps Quote Link to comment Share on other sites More sharing options...
cooperson Posted December 14, 2014 Author Share Posted December 14, 2014 Are you talking about the plate on block side of injection pump as i believe that houses the timing spring or do you mean the lift pump,and as it pumps fuel to injection pump it can't be that cheers Quote Link to comment Share on other sites More sharing options...
dave88sw Posted December 14, 2014 Share Posted December 14, 2014 Had exactly this on a 300 disco recently, the fuel sedimentor on the inside of the chassis towards the back was blocked, i bypassed it and fitted a new filter up front while i track down an alternative sedimentor.

cooperson Posted December 14, 2014 Author Share Posted December 14, 2014 thanks dave88sw but surely i wouldn't be getting fuel pumping from lift pump Quote Link to comment Share on other sites More sharing options...
dave88sw Posted December 21, 2014 Share Posted December 21, 2014 You would get a little, you'd never fully block the sedimentor but the flow is reduced to the point that it won't run, as a test, take the feed pipe off the lift pump, slip over a spare length of 8mm fuel hose and dip it into a gallon can of diesel, if it runs off the can, there is an issue in the feed from the tank, whether that be sedimentor or the pick up pipe in the tank occassionally fractures.

GW8IZR Posted December 21, 2014 Share Posted December 21, 2014 I must admit I got caught out with a 3cyl Ford, no lift pump just gravity fed but its got an in tank filter, which was clogged. It looked like plenty diesel comming through but it ran like a pig. Quote Link to comment Share on other sites More sharing options...
teabag Posted December 21, 2014 Share Posted December 21, 2014 OP posted on 11th December, now the 21st so a bit late don't u think, it would have been sorted by now? Quote Link to comment Share on other sites More sharing options...
GW8IZR Posted December 21, 2014 Share Posted December 21, 2014 I didn't realise there were rules when trying to help. Quote Link to comment Share on other sites More sharing options...
cooperson Posted December 22, 2014 Author Share Posted December 22, 2014 thanks guys for the input It's still not sorted, there is plenty of fuel from lift pump ( i checked chassis filter) and plenty to banjo on pump when I remove screw from end of pump at centre of injector pipes there is fuel but it doesn't appear to be under pressure and i'm not sure if this is significant and no fuel at 4 pump outlets, i've found a breakdown scematic of pump but can't see what could be the problem Does anyone have experience of possible faults/ breakages of pump internals? I'm loathe to take pump off at this stage as it's a big job and my old series 3 is doing what's absolutely necessary Quote Link to comment Share on other sites More sharing options...
dave88sw Posted December 22, 2014 Share Posted December 22, 2014 In all honesty, the injector pump is one thing i've never considered pulling apart at home. It's a specialised job and best left to the pro's. When mine gave up recently, i couldn't afford recon so i bought a good second hand one for £100 and threw it on. It's not as big a job as you'd expect and it's a very good excuse to do the timing belt. I've kept the old pump and if i ever get trouble with the new one i'll be sending it off for refurb so i can just swap them over. Quote Link to comment Share on other sites More sharing options...
GW8IZR Posted December 23, 2014 Share Posted December 23, 2014 Having proved its not external to the pump and that the pump is being turned - it does point to the pump itself. As it came on suddenly and you haven't mentioned jelly or other blockage external again it points to something broke or stuck in the pump itself. As above I'm happy to tackle any job on a vehicle but there are a couple of bits I'd avoid if I can and the distribution pump is one of them. Perhaps trying to get some injector cleaner through it might help ? sorry but I can't be more help here , hopefully someone else will join in now.

cooperson Posted December 23, 2014 Author Share Posted December 23, 2014 Thanks for all the input I'll try the injector cleaner, nothing to lose Having done the waterpump and timing belt a year ago,i was hoping for a miracle cure ! It does seem pump is the problem and like you guys I'll do pretty much anything but strip an injection pump ,errrr no It'll have to wait as I can't afford a recon one and am reluctant to put an unknown secondhand one on with the work involved I'd still like to hear from somebody who has some knowledge of what he possible pump failure might be Anyway Merry Christmas to all Cheers Quote Link to comment Share on other sites More sharing options...
