can u help??????? escort rst cant get fuel to injectors from metering head got fuel to metering head and to return and cold start valve but not to the 4 injectors tried 2 other metering heads and same happens puzzled HELP

 

should get fuel if you press the flap down ... are you gettting fuel before the injectors but not out of them .. or just nothing out from the meteering head ???

 

PUSHED PLAP DOWN NOTHING AT ALL AND FROM METERING HEAD SIDE I HAVE FUEL AT EVERY OUTLET OF METERING HEAD JUST THE 4 TOP SIDE INJECTORS

 

tried fueling ecu (black one)???????

 

NO NOT TRIED THAT WILL DO BUT CAN YOU EXPLAIN WHY IT WOULDNT LET ANY FUEL OUT OF ANY INJECTORS AT ALL

 

well basically its controlled on the metering head by the 2 black boxes on the side of the meter, mine was doing this and i changed my metring head and no diffence, my coolant temperature sensor wasnt being read by the ecu so was really hard to start and ran like poo not fueling properly, i have seen the black ecu's go on ebay for 10 quid so its worth a try but make sure you get one for a series 2 as series one are different and wont fuel properly under boost! not good, check the color of the sticker on the front (will probably be green) and get the same one, series one have blue stickers, lmk how you get on,

 

Sorry but....thats not quite right

Is your car a conversion, or has it had any ropey wiring done to it?

 

not had ant other wirein done and is original not convertion why mate w2hat you thinking cheers

 

I was only asking as not many people are clued up on the electrical system. The hydro electric pressure actuator on the metering head can both lean and enrichen the mixture, if say it had been converted and wired wrong there is a chance this could be closing off the fuel supply. Try taking the plug off it and see if it will inject then.

 

what if it is signaling to stay closed if i disconnect it would stay closed wouldnt it i will try it tho it cant hurt and i need all the help i can get at the minuite cheers mate

 

No, it leans or enrichens the fuel. Its a failsafe system that will run if the management fails, like an XR3i but with limited performance, by unplugging it it just means you get no enrichment on boost or leaning off on over-run, you can pull the plug off while its running and it won't make a difference. Try this before the rest because things like sensors and stuff are only processed for enrichment and leaning, they won't make the difference between injectors fuelling and not.

 

YOUR RITE AGAIN LOL...

bad fuel pressure will give you no results from the injectors, also the HEFP acuator canot shut fuel off it can only widen or shorten a fuel valve to enrichen the mixture.

have you tried cranking the car over with the flap all the way down?
as the s2 fuel pump does not prime, so the car has to be cranking for it to create the correct pressure.

and is your return valve working correctly? as this will give you no pressure at the injectors if it is fooked

good luck matey

 

so doesfuel flow through this before going to the 4 injectors then

 

how do you check return valve i no it is returning through metering head as there is fuel every where but 4 injectors and have tried with flap all way down while turning over

 

Thats right Its basically a flap inside which can move both ways, to richen or lean, fuel enters in one hole, exits out the other.

 

is the fuel coming out of the injector banjo bolts on top of the metering unit or are you just looking at the end of the injectors?

 

no fuel at top of metering head at injector banjos

 

Should be pissing out........if it was working you should see it out of the injectors too but nothing out of them shows no pressure at all, i expect the hydro electric pressure actuator is closing off the supply and sending it all back to the tank down the return line.

 

You have an air leak some where as i had same prob with mine had no fuel from injectors and i changed everything it turned out to be my gay dumpvalve was leaking air

 

Even if he had an air leak depressing the flap fully should show some signs of fuelling to the injectors....

 

as the fuel is mechanicly conected to the injectors, ie the flap is just a mechanical vave that basicly connects the fuel pump to the injectors straight through, i would suggest the pump under fueling. or a blocked fuel filter, as you say there is fuel everywhere, is it pressured fuel or a big dribble?

 

Its definately worth a look, but with no injectors connected there is no opposing force on the fuel system, and i can't see the pump under performing that much. Did you say there is pressurised fuel in the cold start valve pipe?

 

there is shit loads of preasure thire i found that out when i started to crack open other banjo bolts ended up bathing in petrol pluss when i changed metering head 3rd time i it had another sensor on so i left that on so i have tried another sensor switch whatever it is so will have to try pulling plug off and try that

 

yes there is pressured fuel in cold start valve

 

My money is on that Hyrdo electric pressure actuator. My mate converted an XR2 which he now has given up on after fucking up the wiring after i offered to do it for him. He had the exact same things, fuckloads of pressure but none from the injectors, EXCEPT when he flicked the ignition off, and there was a brief spray. Turns out he wired the pressure actuator to the fuel pump relay somehow, (fuck knows how but hey), and after putting some temporary wiring after i suggested it he got fuelling at the injectors. Pulling the plug off should achieve the same result, very quick and easy test.

 

got to be worth a go its right pissin me off

 

Anything simple like that is worth a try, to be honest thats about the only thing between the fuel pressure and the injectors......if it was to do with the metering head itself you usually get overfuelling on one or more cylinder due to the way it works.

 

thats why it has puzzled me i cracked banjos 1 at a time and they are all bone dry

 

Obviously no pressure.....should piss out of any of the injector ones really.

 

i have tried with plug off now and no difference i even took the sensor off and there were loads of fuel trying to get through i also took the return pipe off of the little black pot(unsure what it is) and there is nothing there now could that be the problem and do you no where i can get a drawing diagram so i no i have everything piped up correctly

 

Hmmm, stupid question..........there is fuel in the tank right???

I've got the full documentation from the Bosch book on KE Jetronic, but its all photocopies, and i have no scanner

 

why stupid question thewre were fuel there before and got no action there is plenty of fuel in tank where can i get diagrams no of any web sites or anythin

 

Stupid question just incase the fuel had run out or something. I suppose theres a chance the fuel pressure regulator could of split internally?

Not off the top of my head no

 

i have 2 and they are doing the same

 

Ah ok then. Thats a fucking wierd one then Have you had the fuel pump off? You got it wired the right way round?

 

not had it off or messed about with it so hasent changed since car last running

 

I know i'll see if i can take a picture of the system diagram

 

did you have someone cranking the engine over while you pushed the flap down at the same time?? had to ask cos you never know!!!

 

Good point

 

yes it was cranking over as it was pushed down
