marki Posted June 29, 2015 Report Share Posted June 29, 2015 Hi All. Greetings from sunny Ireland, just before we came away I'd changed the metering unit I now appear to have a problem with it. Car starts fine and runs great from a cold start but once you stop for 10 mins or so will then only fire on 5, no 3 is not then firing for a minuet or so then cuts in but after there seems to be a slight hesitation, I'm wondering if something is sticking n the unit after a stop when it's up to temp. Any ideas ? Mark Here is a taste of what has been going on..... Quote Link to post Share on other sites
Sapphire72 Posted June 29, 2015 Report Share Posted June 29, 2015 Nice photography, marki. No knowledge of the metering unit, but you can do a check to determine that it is not electrical--- just switch ignition wires from #3 with another cylinder. Quote Link to post Share on other sites
marki Posted June 29, 2015 Author Report Share Posted June 29, 2015 Hi. Defiantly not electrical done lots of checks and the injector pipe isn't pulsing, also changed the injector for a new one. Mark Quote Link to post Share on other sites
Pat Kinsella Posted June 29, 2015 Report Share Posted June 29, 2015 Hi Mark. Might be a problem with the valve within the union, I would suggest swopping over No 3 union with No 4 (next to each other on the metering unit) and then see if the No 3 injector and injector pipe work now have fuel flowing / spraying - if ok, then check No4 as this should then have the original problem, Also check to see if any bits of the rubber cone ring have perished and become stuck in the union / outlet Pat Quote Link to post Share on other sites
marki Posted June 29, 2015 Author Report Share Posted June 29, 2015 Hi Pat. That sort of thing sounds more likely, is it possible for the valves to stick ? Mark Quote Link to post Share on other sites
Matt Posted June 29, 2015 Report Share Posted June 29, 2015 Hi Mark, Sorry can't help.....enjoy the Guinness while enjoying the view! Fantastic country side.....just about worth breaking down for! Matt Quote Link to post Share on other sites
marki Posted June 29, 2015 Author Report Share Posted June 29, 2015 Cheers Matt. Must admit its bloody good.... Hope you're well Mark Quote Link to post Share on other sites
Pat Kinsella Posted June 29, 2015 Report Share Posted June 29, 2015 Hi Mark. Yes it's possible that a valve can stick open or closed (possibility of small bit of old "non unleaded type seals" these old seals break down with modern unleaded fuel and can get stuck in the outlet union - ask me how I know), If they stick open - they let the petrol in the injector pipework slowly leak back to the metering unit / main pipework via gravity and back to the fuel pump / tank. its ok when running, but can take a few turns of the engine to get the injector primed and firing correctly If they stick closed, well that's no fuel being delivered to the injector. If you need any bits refurbishing, then Neil Ferguson is the man that I can vouch for - done my metering unit 2 years ago + injectors + prv -- first class service, excellent prices and all parts looking good and working brilliantly Pat Quote Link to post Share on other sites

philrylance Posted June 29, 2015 Report Share Posted June 29, 2015 Apologies for a somewhat obvious question. When you fitted the new injector did you bleed it and was there a nice round cone shape of petrol vapour mist on a piece of white paper, or nothing at all.

marki Posted June 29, 2015 Author Report Share Posted June 29, 2015 Hi Phil. Yes all bled fine but when I did it the car etc was cold. Hi Naill. That's a very kind offer, I hope to have it sorted soon as I've asked Neil to pop one in the post. Cheers again Mark Quote Link to post Share on other sites
marki Posted July 3, 2015 Author Report Share Posted July 3, 2015 Well good man Neil Ferguson came up trumps AGAIN new non return valve delivered to me in Ireland, and now all fixed. I owe him an Ale. Mark Quote Link to post Share on other sites
Alec Pringle Posted July 4, 2015 Report Share Posted July 4, 2015 Indeed, Neil is another 100% TR nugget. Cheers Alec Quote Link to post Share on other sites

re-hiker Posted July 5, 2015 Report Share Posted July 5, 2015 Fully agree with your comment on Neil, he is my Number one and first Choice in the case of Lucas Fuel Injection Problems. Just visited him before Stoneleigh Parts Day, niceShop and very well equipped. Robert Quote Link to post Share on other sites
