Just been out to the car to fit the ECU and 403's. This is after getting a chip from MSD - 380bhp jobbie.

So, ECU fitted along with 403's, hit the start button and whoooph she fired up - ON 3 FOOKIN CYLINDERS

Soooooo pi55ed off. Everytime I have good intention and look forward to doing something on the car there is always something that goes wrong. It really makes me sick.

It is not firing on number one cylinder. If I remove the injector plug it stays the same - if I remove the other 3 it worsens. I just shut the bonnet and walked away

It could have been so easy but yet again I have another issue to track down and deal with. I know I have to check for power at the injector plug, maybe swap the injector to rule that out and then swap out the ecu for a known good one incase there is an issue with that. Couldn't be arsed tonight - really had enough.

Will not get rid, sell or break but by christ do they try your patience.

Thanks for listening

Na, I love it but just wish it was a little easier going is all. It will be worth it when sorted and I'm blatting about in it.

Its a second car and so not the end of the world - could have worked though couldn't it lol.

greys are secondhand are they?

Swap the injector with another cylinder see if it moves the problem with it if it does try tapping the injector with a spanner. The ball might be stuck.

Cosnada

iTrader: (2)

Yes lads, second hand 403's. Got them in good faith and working from MT-Motorsport so I guess they were working well when he broke the car.

Do they suffer?

I will go out and have a swap about but I walked away - it saves having to fit a windscreen too

costina

iTrader: (1)

They can as with any injector. tbh you would have been better off getting siemens 55lb from stu with your chip better injector all round.

Try the above by tapping it or your looking at getting them cleaned but swap them and see if the problem miss moves.

Swap no. One plug for no.2 if your using 071c's they can offer fail

Cosnada

iTrader: (2)

Will have a swap about tomoz.

On 071's too - will whip em out and see whats going on - was running fine on stage 3 - chip one minute and 403's and no 1 down the next.

I do think its a sticky injector as the ecu wouldn't mess about on just one cylinder would it?

Will check the main ecu plug too - never had issues but process of elimination.

I reckon one of the pins in the injector plug is not seated/clipped in correctly

Cosnada

iTrader: (2)

So, with the engine running I guess I set my multimeter to 12v but what reading should I be getting. I know its initially 12v to fire injectors but hold open is lower. Will the speed of the cycles not be detected therefore just see a constant 12v at the meter?

The injectors have a permanent feed.

The ECU's switches the earth, it would be very crude to use a multimeter and the pulses will most likely be to fast to capture. Really you should use NOID lights.

Of course you don't actually know the fueling is wrong, what makes you think it isn't ignition related, if it were me I would start with the basics, i.e. examining the plug(s) etc.

Do you not need a noid light to test injector signal's?

Cosnada

iTrader: (2)

lost now lol - i just want to know if something electrical is present at the injector connector with it off the injector itself with the engine running.

i dont want to know cycle or duration - just if it is getting something.........

Not interested in fueling at the moment - to have fuel would be good lol

martysmartie

iTrader: (1)

Yes, and as I say, you can't really, you can check whether there is power there by using another grounding point, but then this doesn't tell you whether the ground/ECU side is ok, hence why you need NOID lights really.

If you tried using a meter, the pulsing is probably to fast for your meter to register.

Martin

Cosnada

iTrader: (2)

a swap over or new injector will tell me then lol.

botters

iTrader: (2)

have you had other plugs off at the loom whilst fitting the injectors? its very easy to plug the iscv plug onto number one injector and cause it to drop a cylinder, i know as ive been there lol

ram

iTrader: (4)

If you want to see if that injector plug has power then just get an amber side repeater bulb off an old ford (sierra one possibly) and its a direct plug in. if the light pulses then your all good.

ive got one i use but cant remember what ford it was off as some are different.

ram

iTrader: (4)

also done that before lol

Cosnada

iTrader: (2)

Deffo not that - just injectors.

NOID light is only a fiver of ebay but a swap about will tell me - getting nothing now - even an injector plugged in but not plumbed in should click away.

costina

iTrader: (1)

Plug or wiring issue then.

martysmartie

iTrader: (1)

Do NOT do this ^^, you can easily damage the injector drivers by doing so!

As said, have you looked at the ignition side yet?

BRAMMER

iTrader: (23)

Mine fucked a set of 071's and it never even left the garage - your software will be fine it's the other things you need to check - always keep a spare set of plugs mate

Cosnada

iTrader: (2)

Plugs were new - just serviced inc cam belt. Started about 4 times after service but allowed to run and get hot - e.g. fans on. Not turned a wheel yet.

Will investigate tomoz and report back chaps

botters

iTrader: (2)

could very well be sooted up plugs then mate, mine is in storage at my garage now mate and gets driven in and out every day and soots up the plugs to the point of missfiring once every two weeks or so they dont like idling even more so when the fuelling is out slightly, whip the plugs out give em a wire brush and pop em back in

lukeytheduke

did u put the leads back in wrong order? Then check plugs, then injectors.

Mine was in storage for 5years without starting once. We had dizzy rotor replaced, checked power to injectors. Still wouldnt start up UNTILL we dropped an injector on the rocker cover and then the fucker started again!lol so give them a gentle tap

Cosnada

iTrader: (2)

Well, update time........... just been out and had the fuel rail off and swapped 1 & 4 injectors over. Started her up and nothing on number 4 and so issue has moved cylinder. Number 1 cylinder now worsens if the injector is unplugged. The fault is with one of my 403's. I did give them a tap before replacing them and to see if any crud came out but were clean.

ANYONE GOT A SPARE 403 PLEASE?

costina

iTrader: (1)

sorry to here that you sould have gone for siemens.
Can't u phone the guy u got them off to see if he has anymore?

Regards

Paul

Cosnada

iTrader: (2)

Just text him - fingers crossed.

The reason I went for 403's is I love old school e.g. I'm deffo an 8 injector / t4 man ovet GT30 and 4 83lbs. Just my preference.

costina

iTrader: (1)

Fair comment are you running that chip with closed loop? on my set up i'm getting 33mpg off boost. Ive tried greys before and just found they inject soo much fuel at idle making the engine sound nasty only my opinion of course

hope you find another injector or he can replace it for you.

Regards

Good man! Old school ftw!

Mark will sort you out, if they sit for a while they do take a good tap to get going again. May be worth getting em flow checked and cleaned if you could get the injector working again

Cosnada

iTrader: (2)

Unfortunately Mark said he has nothing down to me to sort.

It does click as I have had them out on the bench but it is a different and weaker click to the others. I have tried tapping it to varying degrees but no such luck.

So, no point in cleaning a duff injector really. Looking out for a replacement. Shame really - especially if it had been my every day car.

J1mbo

iTrader: (1)

I'll see if we have a spare at work that can get you out the shit

Cosnada

iTrader: (2)

It does have CL enabled yes.

COCHYN

This doesn't really say anything about the injector as when you disconnect it it's noticable that it was pulsing and providing fuel, it could still be your plugs. The 071C's are great plugs, but once they get sooted up or any kind of contaminent, then it's very hard to get them to work to original standard regardless of the usual burning the tip etc.

Have you tried other plugs yet? For the sake of only £10 a set, it's good to have a spare set.

Cosnada

iTrader: (2)

Hey fella that would be fantasic - fingers crossed

opposite lock

iTrader: (3)

Try Joe at bluesprint i remember he had loads of them at one stage .

Cosnada

iTrader: (2)

I know what you say but they are brand new - 0 miles. Number 1 didn't fire. Moved injector to number 4 and that didnt fire but number 1 was fine (where fault was originally. Cylinder 4 that was fine is now not firing. It has to be the injector.

I am happy that its not injector wiring, connectors, ecu, plugs etc.

COCHYN

Ah sorry, must have read that wrong, though you said it didn't move. Ah well, still buy new plugs as spares And get those injectors to Jimbo for flow testing and cleaning

Cosnada

iTrader: (2)

In all honesty I have not really tried anyone as its the weekend.

I have spoken to Mark but if he aint got any thats no good. I may have a lead with Jimbo as posted earlier.

I will start to have a ring round next week. I am not desperate, more of an inconvenience I guess.

I am deffo not buying a new set I will rip it all out and go back to greens lol
