Hi all i have a problem after installing a second hand injector,so i put in the injector on injector 1 tightned everything up turned on the ignition for the fuel pump to kick in ,then tryed to started the car and after 1 second the engine wouldnt turn,first i thought the timing belt jumped a cog so i took out the rad and turned the crank by hand and everything is free,but while trying to turn it first crank seemed very tight and i could hear a hissing coming from one of the injectors.Has anyone any input on what it could be.I have one of the dump valves off would this make any difference.Any advise would be fantastic.Also the car was runinng fine untill i put in the new injector.Thanks lads

There's no leakage of fuel? You sure the Injector is right down?

Yes there is no leaking what so ever.Also yes the injector is right down and i put the injector cap back on and tightned it down.

sounds abit like hydro lock .. you may of left out or trapped the lower O Ring on the injector you replaced

 

pop the spark plug out on that cylinder and then turn it over by hand see what happens

I would say this too, but you say you can turn it over by hand?

Yea i can turn it by hand,but when i tryed first it was hard to and i could hear a hissing,the hissing stopped and i could turn it by hand no problem

I had the two rings on the injector when i installed it.Also i tested the injector and i got 12.8 ohms

So guys i took out the plug turned the crank by hand and when turning the crank cylinder 1 spits out petrol out of the cylinder

as expected, you've probably pinched the oring so it's shorting on the block, and staying open.

 

Remove the injector and re-fit carefully. then try again!

Ok thanks mate,i will remove it,should i put the o ring of my old injector on it

Guys quick so,i have the injector taken out and put back in again,should i leave the plug out of cylinder 1 to get rid of excess petrol?Thanks

Pull the pump fuse , leave the plug out and turn over on the key for 10 seconds. refit plug & fuse and away you go..

Cheers jeff.Thanks

So i am back to square 1 again,the car is starting no problem i take the plug of the coil pack to cylinder 1,the engine doesnt knock back at all.OMG what is goin on.

The plug is likely fuel fouled now if there was that much going in. Do you own a small blow torch?

Hi mate i also got a spare plug which i tested using the coil pak(gave my self a nice shock) and is working perfectly and put it in,still no joy.is there any way that i can test the voltage on the connector that plugs into the injector.I have cleaned it but still not sure if it is sending power to the injector.

Also just did another ohms test got 12.8

Yes there is, I think you test it on AC to catch the pulsed 12v but I could be wrong. Surely if it soaked the cylinder it's receiving voltage?

Are you sure it's the only one down? Maybe it is firing and you have another one down now.

Yea i was wondering that myself,that why i did another ohms test again.Dont know what is goin on.No mate it is the only one as i pluged out the 2-6 of the coil pak conectors and the engine cut back on all of them bar cylinder 1:helpsmilie:

The other option of there is spark and fuel going in is there is no compression. If you've been running that cylinder like that a while, that is very possible. However I'd expect to see a fair bit of smoke/steam.

fresh plug time!

Yea it isnt smokey at all,since i got the car i would say i havent put 200 miles on the clock,also i removed the fuel pump fuse and turned the engine to remove the petrol and the piston shot the petrol out if that makes any difference,well i have a compression tester so guess that is what i will try next

fresh plug time!

 

 

All six isn't a bad shout

So guys i did a compression test on cylinder on with throttle fully open got over 150 psi.That you guys think?

Sorry ment what you guys think:oops:
