Hi Gents Thanks for coming back so quickly. I have changed the Ignition Amp but to no avail. The dizzy it has in it is a power spark one which has the slot for the oil pump in it but the engine i have doesn't have the same oil pump drive would this matter? It also has an lpg system on it and i am wondering if there is an issue with that. Would the ECU have anything to do with it? Would it be worth swapping for another? Or is there a way of bypassing it all just to get it running?

Hi All I have a 3.9 V8 Disco 3 door bought as a non runner but i'm struggling to get it going. At first it wouldn't do anything then i bought a bypass for the immobiliser and it now turns over but i am unable to get a spark. I have changed the coil, put a live straight from the battery to the coil +ive and a spark plug in the main lead from the coil but no spark at all. Does any one have a wiring diagram i could look at or would you be able to tell me any other bits to change? it does have an lpg kit on the vehicle too. The engine isn't staying in the disco it is going in another project so all i need is to get it fired up and see how it runs. Any help would be much appreciated. Thanks in advance!

Evening all. I have a 1985 rrc with a 3.5 rover v8 with twin su carbs. I have only just recently got the car up and running and it has never been quite right. It starts and ticks over fine. It will rev fine when stationery. Once I take it out it will be fine in 1st and 2nd when pulling away but then when changing into 3rd to gain a constant speed or if I start to go up a hill it just dies and the power disappears! To make it to the top I have to gear down and rev the engine more just to move forward. Would it be the timing that isn't correct? Any help would be much appreciated. I have read around trying to find the cause and haven't had much joy! Thanks in advance.

Evening all a bit of an update for you and hopefully a bit more help for me. Checked the breathers they are clear. Opened the oil filler and ran it with that open but no real change there either. I did notice I had coolant resting on the valley gasket so I have stripped the inlet manifold off to see what's leaking. Any tips for the best way to put that back on. May that be where the air leak could be? I also checked the pistons too and they were down when it opened the throttle they moved up slightly. It's really strange it just won't rev or idle!
-
Excellent I will have a look at that this weekend. I think the pistons are permanently down but that could be wrong. How do I check for an air leak? Spray easy start and see if the Rickover raises? The oil filler to the engine or on the top of the carbs? Thanks for the help guys.

I'm pretty sure they are Hif44 but I'm not too sure how do I tell?

I'm back! I've eventually got the engine started 3.5 V8 on twin Su carbs and it's ticking over fine on the choke but as soon as I turn the choke off it splutters and stalls. I have tried adjusting the mixture but to no avail. Even if I try to give the engine a bit of throttle it still fails. Any ideas? Cheers

It's is good once it works! Just annoying when it doesn't. Ah that's a good idea. The one I bought works off a tyre. It's got a tyre valve connector on to send the pressure through it. Quite a good idea actually. Now I have a nice solid pedal I'm leaving it we'll alone. Just to get it running properly now and then the last things to sort are the dreaded electrics! I can't find an auto electrician to come and sort it so looks like I'm going to have to learn how to use a multimeter. Thanks for all the help guys. Boydie I lobe that!! Sir Percy Verance. Think I will have that printed on the bottom of my reg plate.

Evening Gents it's sorted! Davo yes that is the one I have. Unfortunately the plastic part has snapped went to get a new one at my local place and they wanted £50 so I've capped it off for the time being as it's only a warning valve. The problem was the plv it had a blockage and wasn't sending any fluid through the rear port. I changed that and invested in a Gunson easibleed and hey presto it's sorted it. Nice solid pedal now. Thanks for all your help chaps.

Just to keep you posted it's now back off the car and in bits. I have bought a service kit with new seals and washers to change all those then try again. I have read in my haynes tonight that the pressure switch in the master cylinder needs unscrewing when bleeding too that's something I didn't do so could that have also caused me these bleed problems?
-
No I had stripped it to check everything looked ok. I will change the seals as they are probably worn. It's as though it pushes a bit of fluid through then sucks it back up again. Haha. I will change the seals and see how that goes. Thanks once again guys.
-
Thanks for the advice chaps. I had another go yesterday and still got nothing even with the new plv. I took the lines off the master cylinder and pressed the pedal and it's hardly pumping anything through there. Do I need to prime the master cylinder first? Shall I just have a go with a brake bleed kit? Or do I need to rebuild the master cylinder with a new seal kit? Cheers will

Boydie you may have just hit the nail on the head with the limiting valve! I wasn't sure what that was. I did take the line that goes to the t piece off when my mate was pressing the peddle and I was only getting a dribble through then! I will take that off at the weekend and see if I can source a new one. Thanks for that. Bowie think I will invest in one of those. Saves me having to cook my mate lunch every time and keep him filled with tea!! Thanks chaps I will keep you posted.

Excellent thanks for that. I will try that this weekend. I have had a friend pumping the pedal while I unlock and lock the bleed nipple but it still only dribbles through. How long should it usually take for the fluid to run smoothly? Cheers Will
