Car Is Running On Only Three Cylinders 205 Gti 1.9

[rallyeluke 0]

as above my 205 gti 1.9 is running on only three cylinders i have diagnosed that it is the second cylinder in from the gear box side that is causing the issue.

 

i have taken the ht lead off the plug and put an old plug on the lead and it has a very strong spark so no problems there.

 

i get the impression the injector is some how blocked as there appears to be no fuel in that cylinder, i checked this by runnning the engine briefly without that plug in and could sense no sudden smell of petrol or see any vapour coming out of that pot, i then swapped the injector leads around between 2 & 3 cylinder and the cylinder next to the problem one has no issues fueling its injector with the lead off the possibly bad injector so i imagine that the leads are not at fault.

 

where do i go from here?

 

 

would love advice please.

 

 

cheers lucas

check the pins in the plugs, its not unknown for them to become loose and not make a good contact, you pushing it onto the other injector could have been enough to make it contact.

Or if that doesn't work you could take the inlet manifold off complete but leave it laying loose, and turn the engine over for a couple of seconds. You should see fuel squirt out of each injector.
