[4u2nvrs]

my erst preety much standared had piston slap so i took the engine out and rebuilt it. i finished putting it in yesterday yippee. i took it back home from my garage and it ran out of fuel (i think) it was well in the red. so this morning i put a jerry can of fuel in and it fired into life after a 2-3 second cranking yess. i then drove the car 10mile home i then left it for a couple of hours and went to go out in it. it wouldent start, there is fuel getting to the metering unit but is not getting to the injectors, ive tryed pushing the flap while cranking and nothing, very strong pressure to the met unit as it covered me when i loosend the feed. is it possable that 2 of the connectors the wrong way round at the back of the head? when i drove it home it was loverly dident miss a beat. can any1 help

If you have fuel getting to your meetering unit, but not to your injectors theres probably going to be something wrong imbetween the meetering unit and the injectors then. I doubt you have got the fuel lines on the wrong way as it would probably be quite obvious when the pipes don't reach the correct part of the metering unit
Have you tried taking the fuel distributor out of the metering unit and checking the metering pin, this may have become stiff, not allowing any fuel through (this had happened on mine when i bought it). Also check the roller the pin sits on rolls freely.

hi mate have you checked or unplugged black relay under dash then put your hand on pink relay to make sure it kicks pump in you are feeling for click at relay whilst listening for pump noise if it doesnt kick in check heated seat fuse if s2 if s1 check centre fuse running long way to rest of fuses hope this helps you

i can hear pump priming and also running whilst cranking, very good pressure its got to be metering head or no voltage to the cut off valve. i found this have a look as im doing all this 2moz so will let you no.

its got to be summit daft as it ran so well 2 hours prior.
my mate gave me a complete metering unit he had but it hasent got the 2 electrical sencors on it, is this because its off a 3i,

[studabear]

check for air leaks, esp boost hoses

as i said it drove perfect, i did go through all the pressure pipes, as i did everything,
im going to cheak the returne pipe, strip and clean metering unit 2moz

hi mate did you check relays and fuses if temp gauge went into red it would shut off fuel via heated seat fuse s2 or centre fuse on its own let us know how you get on also fuel pump may sound as if it working but is it check pressure

[4u2nvrs]

it would turn out all the water has found itself in the sump, the metering unit was covered in coffee colured yougart, so i traced it back to rocker breather from block (right side) dip stick was well over max and was also coffee colured, pulled the sump plug and there must of been 1 lt of water before the yougart started coming out.
i took the water cooled oil cooler off thinking must be that pressure tested it and all good.
the only thing it can be is headgasket which belives me to think the hbolts my mate gave me were not none stretch, i no ino ino for the sake of a tenner should of got new. anyway hgasket and bolt 2moz will let you.

[4u2nvrs]

put hgasket/bolts filter on today, striped replaced o rings in metering head and cleaned.
still no fuel to injectors.
as i loosend the small bolt on the regulator fuel pissed out the injectors (i undid them) do you recon the fuel pump hasent got enough woosaa and is nackered or is it the reg.
pressure to metering head, untightend the return at the back of the fuel reg and nothing there.
HELP.

Help.

did you check relay under dash black one and the fuses does fuel pump kick in can you here it you can bridge pink relay pin 85 and op think 87 if i remember right sounds to me its got to hot and shut down fuel system which would be fuse or relay or both let us know how you get on

[4u2nvrs]

checked fuses under bonnet all good, there is two big relays in the fuse box is one of them the relay. i cant see any relays under the dash. can here pump priming then stops then crank and you can here then aswell, so i think the electrical side of things are all good.
should fuel be returning to the tank as im cranking, nothing is coming out the return on the reg back to tank.
thanks for your help.

measure fuel pressure mate at filter see wot you get if you aint got gauge see how fast it fills milk bottle shud be relays under dash press fuel flap down cupple of times to get pressure at injectors dont think they return fuel till running

[4u2nvrs]

replaced the metering unit and all is well, MY MISTAKE WAS TAKING APART THE HEAD OF THE UNIT, the petrol gauge is getting a little lazy and although there was fuel to the filter it was dregs. fuel pressure gauge would of told me this in the first stage and saved me money and time.
i took the metering unit apart previous and replaced the o rings, it would
appear the o rings i put in were the wrong size, i would recommend going to ford
for the correct ones as mine were out of a multi pack with every size, ther is a lot of pressure in these units and altough the rings i replaced looked the same they oviously are not. could of possibley of been a worn shaft in the centre of unit.
DONT TAKE THIS UNIT APART CHEAK FUEL PRESSURE FIRST.

Put out your filter box and you will see it

Check the yellow plug under the inlet mine came of and I had the same symptoms
