rebuilt my cvh now it wont start ??

[stevostyles]

as header ive built it and it wont start now i really dont know whats wrong ive tried spark and it is sparking ,tried fuel and all are slightly damp except plug 1, so i took off the injector no1 and cranked it over but no fuel is present ? (is there supposed to be fuel squirting as iam not getting this) ive tried 2 new pipes now and still the same result .but the bolt on the metering head on my no1 supply has fuel when i undo it like its pressurised the only thing ive noticed is a loose connector (looks like a double spade connector in black comes from the harness near the coil) cant see were it goes . have changed inlet manifold to polished without knock sensor . have changed the head and put a piper 285 t2 + pulley on. just looking for ideas/ suggestions that may help me before i go putting my new loom on, so i know it works again before getting potentially more problems with new loom. cheers

dizzy looks very advanced for a start?

fuel should come out of injector during cranking yes, is the fuel pump running when: flick ignition on and during cranking?

[StephenC]

[stevostyles]

yeah sorry i was trying allsorts leads too.

[vroooom ptssssh]

looks like they are in the wrong positon, good call Stephen!

it primes yes

[gremlin]

The diagram above is wrong too.
On an Rs Turbo, No1 is at the 2 o'clock position (closest to the plug).
Then running 1-3-4-2 anti clockwise looking endways on to the cap.

[StephenC]

went through all this when I finished putting mine in for first time, fuel wont appear at injectors unless you depress the piss flap in metering head whilst cranking engine, bet if you take injector one out and do this fuel will be everywhere!! know mine did, thats after Id tried two metering heads and fucked about for ages. Spent a day trying everything for it all to be leads on wrong position!!! If your getting fuel and a spark then it can only really be firing order thats stopping it from even starting.

I'd go with that, probably why I got mine wrong in the 1st place
best way is take plug one out, wind engine over by hand (big spanner) and get 1 to TDC, where rotor arm is put lead one there and work your way around distributor 1-3-4-2

i know fuel pump primes there is spark and there is fuel in the metering side but newt coming out the end of the pipe ?? and thats 2 pipes .

unless this is a little bit of fuel until i hold this piss flap down a little as you say lol sounds like a good idea to me as i didnt know this. cheers

G.

i will try this as every one posts the other pic up and that is what ive been going by
so you say this 1342 is the correct way for an rs?

[gremlin]

Here you go, the right order and positioning of the h.t leads for a Turbo. G.

[StephenC]

the order is right but its the starting point thats different, as said plug 1 will be at 2 o clock, do as above to double check, whip plug out and shine torch down hole and wait for piston to come to top.

[StephenC]

good lad gremlin should be sticky on here as its a proper common mistake

i hope the order and this piss flap is the source as iam so desperate to drive it . had it 4mnths and never driven it so as you can imagine taxd motd insured and waiting for me to sort the job out.
will try 2moz

[StephenC]

it'll just be the order, shouldnt need to mess with the metering head, its just a check pushing the flap down to see if fuel comes through. Exact same situation I was in, spent all day fucking about with it after taking a year + to build it and it wouldnt start, was about to set it on fire when mate came down, rearranged plugs and boom, fired straight away, ran like a peach best of luck

[gremlin]

Hopefully the correct h.t sequence should get her running.
If the leads haven't been in the correct position then I'd say it's odds on to be your problem m8.

Also remember to have all your electrical leads and importantly, earth straps attached...

I spent a couple of days once upon a long ago shouting, swearing and wheel kicking after dropping an engine in only to forget about re-attaching the bonnet earth strap thinking it was of no consequence.

Let us know how she goes anyhow.

sure will cheers guys hopefully with the good news

[stevostyles]

ive tried it 1342 anti-clock held flap down a bit and no its still not pumping ewt out of injector pipe 1 ????????

[gremlin]

Have you cracked the banjo for injector No1 at the fuel distributor to see if fuel is getting to that point?

G.

G.

correct there is leaks a lil when i undo it. but newt coming out of the end of the pipe and ive used 2 pipes now and its still no go

taken my dash out ready for when i can get the new loom in.

ARE XR3I PIPES THE SAME AS IVE CHANGED NO1 INJ PIPE ??????

[vroooom ptssssh]

maybe the fuel pressure isnt high enough, the operating system pressure is 6bar, if its not high enough you'll get no fuel out the injector....

nice thought .
what causes this ?

[StephenC]

injector 1 isnt clogged is it? tried swapping injector for #2?

[stevostyles]

ive removed it and nothing going through the pipe ?

MFI is it?

Is the return system ok? Not blocked as the AIR pressure piece (dont know its name) If that won't let air escape you'll get no fuel upto the engine or past the metering unit,

That's if it is MFI!

[gingerturbo]

have ya kinked the pipe at all

[stevostyles]

no i changed it tho as the retainer was broke so thers me in the dark undoing it and twisting it so put a thread up and askd if 3i pipes fit and they do so i got some and fitted no 1 and hasnt worked so ive tried all the pipes i got and all same result. cheers

[botters]

take the fuel return pipe off and blow down it with an air line as it may be blocked mate this can cause low fuel pressure

[botters]

wherabouts in preston are you?

[gingerturbo]

is it ya metering unit

[XR2]

Firing order is the same on all CVH engines, just the ESC-II ones had the starting point turned for 90° because of a different arm inside the dizzy. But all pictures you can find in Ford manuals and books like Haynes show just the non-ESC ignition.

MFI is a fine system but it's tricky when it won't work.

It should start and run on three cylinders so I think it can't be just one injection line or one injector.

XR3i and RST lines are all the same, XR3i are just a little bit longer. But they will be fine for testing.

Give the fuel pump a short cut so it runs when ignition is turned on, push the metering unit flap down and check if there's fuel on each injector.

Second try: the wiring loom connector on top of the dizzy itself or the pins inside sometimes come loose, so the fuel pump won't get a rpm signal and won't run. So be sure the fuel pump is running when cranking!

If this all works, try to get a pressure testing device and check all fuel pressures. If these are also correct there might be something wrong with the KE-Jetronic or one of its electronical devices and then I'm the wrong one to ask.

Because of different banjo sizes it's nearly impossible to put the injection lines on the wrong way. But be sure they are all in the right place! And I hope you also use a new filter?

[rs_turbo_tony]

have you got injectors to air flow meter on correct order . also check fuel electro magnet
