i have a decent fuel pressure up to the metering unit but no pressure after or fuel in the injector pipes etc, i got the car to start by pushing down the plunger slightly, so i adjusted it down but the car still wont start, could it be an air leak of sum kind?

anyone else had this prob or no what it is

thanks in advance

 

hi m8 have u had the top off it coz there have a black rubber joint in them think it mite be a diaphram of sum sort and it cud be split and losing pressure

 

u mean the metal cassing with 3 star drive bolts?

 

ye thats the 1 its got 4 i think just be careful coz u can round the heads of
very easy like i did.also try turning the car over and pushing the air valve down manualy on the unit i got a flame out of myn b4 but it did start after i dun that

 

yeh it started first time so i adjusted it but know it wont start again

 

theres a black plug on one of the sides off the unit there always fcuk up so try taking it off bit of wd in there and try again,its got to be sumting silly but just finding out what

 

You may have air trapped in the metering head mate

Crack the bolts off the top and crank it over until fuel pisses out!

 

u mean the bottom of the injector pipes or the actual bolts for the metering head, ive tryed the pipes

 

The banjo fittings on the pipes.

 

done, thers no pressure were cracking one off i mean cracking it over

 

just cn ur other post there with the head off if just done the same thing head and wen it was all boxed u and ready to try i had the same problems wudnt start so i done all them things iv said and i also cracked of the fuel lines at the top of the unit turnd it over and waited for the fuel to cum out my b try that and if it still dont work m8 u mite have 2 get sum 1 out to have a look,just go round ur full enging bay and make sure every thing is on rite i.e sensors fuel filter fuses wires
gud luk m8 hope its nothing big

 

cheeRS mate but as im a mechanic i cant really call any one out lol, i will get it solved just a matter of time and maybe ŁŁŁ

 

I normally crank the engine over and hold down the plunger and this normally does the trick but if you have had it to bits then who knows

if you push the plunger down does it go down smoothly or rough
if you push the plunger down when starting does it start and run
also when pushing down can you feel any resistance in the flap itself

 

plunger feels smooth and thers enough clearence to the bore etc

the car did start first when the plunger was down but now it hasnt made a difference, the metering unit had a puddle of fuel at the bottom, thats been cleaned up now and thers no sign of any leaks

 

when it does fire its a strugle to keep it idleing

 

the plugs are prob wet fella disconnect the cold start valve and clean the plugs up
you did jet wash the engine it might have some water in the boost pipes or the air filter is wet
does sound like the a/f meter is at fault
check that your oil is not mixing with petrol too fella

 

If you've got fuel in the bottom of the metering unit box then the metering unitself has probabl gone!

Quite a common thing

 

i stripped it today and ther was loads of shit inside cleaned but still no joy, it fired once but then not again, wheres the best place for a metering unit, ebay? thanks

 

pm sent matey

 

Are you getting fuel trickling out of the metering unit?
