put new engine in wnt start, juice wont go from meterin unit 2 injectors,
changed the followin,,

both ecu, black n silver
fuel pump/relay
meterin unit x3
plugs+leads
all sensors/clips on right

starts for 1 secound on 2-3 cylinders then cuts out, must b the unmeterd cold start supply


had enuff now bin off the road 11 months, im going to efi it an hope it starts then, i hav all the parts ready any more ideas b4 i start doin it cheeRs

 

Have you swapped the injectors for known good ones?

 

nope i havnt, i thought if the juice wasnt leaving the meterin unit it wasnt the injectors, could i be wrong?

 

crack all banjos on meterin head see if fuel is at all the banjos good old mfi units are s##ty and very temprimental

 

iv took the 4 injector lines off the metering unit, got sum1 to turn it over, you can see the fuel sitting in it wer i took the 4 bolts out, wen i press the flap down 5mm nothin happens, wen i push it right down it comes out but not wiv any pressurean the injectors are like making a buzzing sound?

 

sounds metering head problem mate soon as you touch flap it should come out or maybe your pump is on way out not getting enough pressure up tyr undoing banjos on filter to meterin head if there is loads of pressure buildup there its most likely meterin head

 

yh i have done mate, i hav loads of pressure from the filter 2 meterin unit, would tht mean my meterin unit is faulty?

 

Have you tried the two man method. One person turns the engine over while the other applies a small amount of pressure to the flap. This should force the fuel up to the injectors and fire (hopefully)

 

yh iv tried tht method and bridging the pump, still no joy, wen i push flap no petrol comes out

 

definatly meterin head problem mate there not worth pissin about with look for a new one

 

better still bin all mfi stuff and go efi,had the same problem with mine and never figured it out done the same with another metering head aswell so binned it all and went efi instead,much better

 

is the pump working corectly and corect fuel supply? remove the fuel return pipe that comes off the pressure regulator at the back of the metering unit place a container to catch the fuel then bridge the fuel pump relay for 20 seconds and you should have roughtly 0.75 of a liter of fuel come out.

 

iv tried bridging the pump, i will try takin the return off 2morrow cheers

the head on the hydraulics, 2 threads out the 8 had longer thread, so it was jus out, used 2 washers to equal it off so the valves sealed properly
