Just a quick question to put my mind a rest, what are the symptoms of a failed ' o ' ring on an injector? Mine still won.u start, changed to a series 2 ptu dried maf that was possibly damp.

The car tries to start at first then nothing managed to get a cough and a splutter last night

If you had a failed O ring you would have a smell of fuel in the engine bay and running rough, firstly check you hear the fuel pump when you turn the key, check the cas plug as this controls the injector firing, check all connectors are clean and seated well.

Although you have changed the ptu, check for spark and using a multimeter check the ohmage on the injector terminals.

 

It could be any number of reasons why it wont start, but need to do a process of elimination.

mmm i did change a injector hence the reason for the question as it had died 2 weeks ago,there is a strong smell of petrol wheni try to start it.I have been round lot of the connectors and when it stops raining i wll check for a spark again.Unfortunately reading the history of this car it is gremlin that keeps appearing and last year had a similar problem but with all the fiddling under the bonnet i fixed it but don't know how as i checked and cleaned so much....never owned a car that has tried my patience so much but i still plod on :)

I know what you mean lol, patience is a definite requirement as part of zed ownership, you may have twisted or snagged the O ring when replacing the injector, has been known before.

i had a gut feeling,the injector went in to well (was dreading getting the old one out) i don't like it when a job goes smoothly i always think something will go wrong.I will grab some new o rings and whip it out anyway just to rule it out.It took under an hour to change the old one
