Hi, can anyone tell me how I can check to see if a fuel injector is not working. The car is a 2000 3lt v6. :-\
-
What problems are you having with the car? What makes you think your injector is suspect? :-\

The engine has a regular misfire. I have changed the diss pack and plug leads. Though I haven't looked at the spark plugs they were changed a couple of months ago.
The misfire started quite suddenly after the heavy rain.

Check fault codes ,should throw up the eml light on dashboard unless bulb has blown or been removed.

Nah, not on 3l
No fault codes and a misfire is usually HT, but as this has been checked, worth checking other options....

Any evidence of water around/on/above the new dis pack :-\

The diss pack is dry and along the well where the plug leads are though the were wet when the misfire started. The diss pack is new and anyway water cant get into the bit where the leads plug in, the seal is too good.

You reckon? Seal the scuttle up as per...

... and report back :y

Already did the scuttle. and the sockets on the diss pack dry as a bone.
-
Easiest way to check injectors is to turn the engine over with the leads off, then smell / inspect each plug, although Im surprised you haven't checked the plugs yet, even if they are months old.
Are all the leads securing properly at both ends, and have a physical check at the conductors in case they have been pulled or stretched when being removed.

I certainly wouldn't say the windscreen seal isn't a problem, as that link. While its fine if fitted correctly, they do have a habit of coming adrift from the screen ime.
Not sure why, but the last 3 3.2s I've had all had a loose screen to scuttle seal, where it's come in lipped from the screen.
Obviously if that happens, all the water off the screen just poors into the engine bay.
A test with a hose or a watering can will find any leaks.

Yes this where the original problem started think though I have sealed it up now and it doesn't seem to leak anymore. Same thing with the last two Omega's.

Yet the missfire persists? Maybe a plug not fully seated on the dis? Needs further inspection anyway.

I don't think its fuel or diss pack now. It's a regular misfire on one cylinder so I am suspecting a lead or plug. Going to have a look tomorrow.
