Fuel flooding metering head then sump

Post

Back to the top
Just realised the gap in the metering plate would not be the cause of the injectors running when they shudnt be as it's the action of the plate arm lifting which lifts the plunger allowing fuel to the injectors.

Sorry…I'm on the brink of my mechanical knowledge and skill as you have probably guessed lol

Another update

Think I've found the reason my injectors are running when they shouldnt be.
"Distance from the fuel distributor mounting surface to the sensor plate lever roller when at rest should be 19mm"
I measured mine and it was 14mm! Meaning it was constantly pressing the plunger up even at rest. Someone must have messed with this thinking they were making the mixture richer so it would run better possibly. I've adjusted the idle mixture adjusting screw with a 3mm Alan key so the measurement is now 19mm! Thus will not press the plunger unless the plate is raised.

This still doesnt explain the petrol in the air box though I dont think. I do think that is down to leaky dist seal around the plunger

POSITIVE UPDATE

Finally got the resealed fuel distributir back on and tested the injectors with the fuel relay jumped as before

The fuel distributor no longer leaks into the airbox 🙌
The injectors now only spray when the air sensor plate is lifted 🙌
(So that was definitely the CO screw adjustment)

Now I have to find out why injector 4 isnt performing as it should. In the previous tests this was working fine so I'm hoping abit of adjusting will sort it and it isnst something more serious within the fuel distributor (I do not wana split that again lol)

Yes Paul I wish I had tried this yesterday I shall try swapping an injcetor round this morning. I thought no fuel got to the injectors with the plunger down you see.
I will report back with my findings. I know injectors are expensive but I hope it is the injectors

Sorry for being a pain…right….so number 4 injector has been spraying fuel with the plunger in its rest position so I swapped number 4 injector for number 1 injector and the problem was still at the 4th injector so it's got to be a supply issue.
Number 3 dripped with plunger in rest.

I had taken the fuel dist off the air sensor so cud see exactly what the plunger was doing. When I pressed it up, 2 3 and 4 sprayed but 1 didnt.

Is this now beyond the adjusting stage and there is something definitely seriously wrong with my fuel distributor aka just buy a new one or get it sent off for proper refurb?


Cheers for any help/advice

THE BANJO is the bolt and hose connection to the head, 5th injector and wur.  bolt with flow holes that go into round connection to allow angles on pipe to be reached safely.

think what paul is saying is to open the hose at sensor plate side to see if fuel reaching line.  then chgeck further to injector  , crack that fitting and allow free flow to prove line is clear, thatwould then leave faulty/blocked injector

Yes sorry I may not have been clear enough. Yes 4 is getting pressure…even when it should not be.
The new problem is that number 4 injector sprays as soon as the ignition is turned (with the fuel pump relay jumped) with the plunger in the rest position (air plate sensor arm down. None of the other injectors spray until the sensor plate and arm is raised (plunger pushed up)

surely nothing should get a fuel delivery until the
engine is cranked then that would be the fifth injector

Exactly. I've jumped the fuel relay solely to test the injectors. I've disconnected the power to the 5th injector.
So I'm getting a fuel delivery to injector 4 when the plunger is in the rest position. Dont understand it at all

Update on this hoping can get some advice

I've resealed the fuel distributor and changed a leaking injector I no longer get fuel into the sump or fuel into the air box

Went to start her up and would not start. I've done a test for spark and I'm not getting a spark either thru a plug or via a screwdriver jammed into the spark plug wire connector.

After this I'm abit stumped? All the leads, dizzy cap rotar arm plugs have done zero miles been in about a year while other things were being worked on

Are you getting 12v to the coil?

Hi mate, I didnt have a multimeter so just ordered one off Amazon for delivery tmoro. I put all new leads plugs and dizzy cap and rotar arm on. Just hoping they were all the correct ones

I've never seen it start up with the new bits on (dizzy cap rotar arm ht leads spark plugs) the mechanic i sent the car to when I cud not start it said that he had started up with them tho. Obv taking his word for it I never saw it

20210415_122500.jpg Taken the ignition coil off for testing and when taking he bracket off that had an earth wire to connected to it….the cable just come off with bracket. The other end wasnt attached to anything so is it just a case of attaching it somewhere? No idea where it connects to though 20210415_122514.jpg
