Try a new set of plugs. If youv contaminated them with excessive fuel they may be no good now. If the pipes were wrong way perhaps a small amount of fuel was finding it's way to the rail but not enough to allow it to run.

 

Just a thought, has the car been stood a while? If the fuel is old it may have gone off & won't ignite from the spark.

 

No fuel was put in when car was drove to workshop..

If u connect fuel lines wrong way so it builds up and doesn't put any fuel in the rail the car will try and fire up on the fuel that is left in chamber etc,, actually coughs and kicks..

But put fuel pipes on the rail the right way I'm basically drowning them and it won't fire


So what causes this?

 

Any ideas why?

 

Iv also checked the ones marks on cam sprockets all seem in same place as old engine when turning the crank over by hand


So what's causing my car to cough when fuel is not going into the rail

But as soon as its all plumbed the right way it won't fire but just floods the engine with fuel ?

 

Is it flooded? Try unplugging the fuel pump & cranking it over for a while to dry it out & then plugging it back in to see if it will start.

 

I removed the delivery pipe to the rail into a bottle( didnt knoe how stop pump)

cranked it over and then it proper started to cough like it was trying,,(never got to sound like this so far) but then overly just cranked over as no fuel was going to injectors as it was just trying to start on the fuel left in the engine,,

Iv removed plugs now and dry them and refitted


But I'm pretty sure if I refit fuel line to the rail It will just end up flooding and still not firing

Seems like its getting to much fuel to me,,

 

So one most have idea what I can check or try now?

 

Mate I'm feeling for you on this one now. Maybe it's time to have a mobile mechanic out to it or even see if anyone on here local to you will spare you a bit of time and pop over and help, it's amazing what an offered case of beer will get you. Put the offer out and ask, some good lads on here.

 

Try swapping the injector wiring around. Front to back and vice versa both sides. Cant remember the colours. But they should be the same. I.E. Both black plugs at the back

 

All 4 injector plugs r same colour,,(grey) I can only tell apart because of colour wires going into the plug,, I have the same colour wires going to plugs on front and same again with plugs going onto to back injectors.. I will swap them around tho as worth a try

 

Is the fuel pump actually working?

 

Yes pump primes up,, turned it over with fuel pipe off into a bottle and flows out,, can also feel the pipe pulsing when it's connected back onto the rail

 

Changed the injectors plugs around., didn't make a difference and really had to stretch to get front plugs on back so I would say had them the right way,,

 

Did you do a compression test?

 

No I'm going to do later,,or tomorrow,, il not be happy if its knackered seeing as was ment be running from a member off here,,sounds like compression on it as feel it coming out plugs when removed when turning crank by hand,,also out intake pipe when plugs are in and filter off

 

While the plugs are out also out check for spark out of all leads & see if fuel mists out of the plug holes while cranking to ensure it's injecting fuel.(make sure no sources of ignition while doing this as fire hazard)

 

I removed the leads last night to double check for spark,,could only do drivers side as couldn't see the other side while cranking,, they sparked but seemed abit yellow rather than blue?

Surly I'm getting fuel as every time I remove plugs if a flick them u can see specs of fuel that have come off the plugs, and I have fuel coming into rail from filter

 

Try new plugs

 

Brand new plugs in there

 

for a start the fuel filter hose ( feed hose ) should go in the top most port of the 3 on the manifold
return should be in the middle port
tank vent ( smaller pipe ) should be on the bottom

clean the plugs ( ALL 4 ! ) properly

also to note the injectors must be sealed correctly , if using the old seals upon priming what can happen is the bottom seal inside the injector seat on the manifold can leak fuel straight past into the bore rather than using the injector to control fuel distribution , so you will have 3 bar of fuel going straight in there rather than intermitently pulsing through the injector

you say you have changed a lot , my bet is that the fuel pipes were on incorectly at one point and also the injectors are NOT seated correctly and hence the problems you are encountering

my advise would be as above:

make sure fuel lines are as i said
fit new injector seals
clean the plugs correctly and gap to 0.65

if problem persists check fuel pressure as u may have a seized fpr

 

Thank u for that,, fuel pipes r the right way on,,

As for injectors, the rail was removed to paint the inlet manifold,,

Do u mean the rubber seal that sits in the manifold? (This area was all taped up while painting painted) or is there a seal on the bottom of the injector itself?

By when putting it back together they seemed to push in the seal in the manifold before fitting the bolts on the rail

 

all the seals , manifold ones and internal ones

reason im sayin is ive had this issue before a few times , once was a stuck fpr ( closed ) and other time was botton injector seal ( inside the rail ) was leaking , causing fuel to go direct into the bore rather than through the injector , was spitting it out the exhaust too

 

Ok thank u for that information,, the injectors was pulled out but not apart from the rail so possibly bottom o ring seal off the injector,

, should the injectors just push in the inlet manifold and kinda pop in to stay in place, then the bolts for the rail

 

yes

if the injectors were fine in ur old car ( and it is indeed your injectors and not other ones ) and they have not been disturbed from there rails then they should be ok

the manifold o rings maybe give them a coat of vaseline , this will help seal them , just remove them then smear it round them and put them back in , otherwise buy new ones

 

Yes the injectors was not removed from the rail,, the rail was removed from the manifold with injectors still connected

I will try the Vaseline around the manifold seals,, would this really stop it firing tho?

I'm only asking as unsure,,

 

Have you tried disconnecting the fuel system entirely, then spraying cold start or carb cleaner into the intake and seeing if she runs? If runs fine like that then you definitely know you've got a fueling issue.

 

Right be in garage,, the checked time timming etc and all fine,, but still won't start,, there have said that there is whisp of smoke coming out the intake pipe?

They have said that to cause that would be

Timming ( which they checked)

Or valve trouble


To be honest iv had a gut full now and very pissed off or someone selling a engine that clearly is not running!! And has internal problems!

 

Really gutted for you mate. By a wisp of smoke coming out of the intake I take it they've done a leak down test with smoke? Surely they would have done compression test before this? If poor compression with correct timing must be valve, gasket or piston rings?

 

They said smoke was coming out the intake when pipe while cranking the car over,, surely this should be out exhaust not coming back out intake pipe
