I've been preparing my car for weeks for a track day tomorrow. At lunch time today, it decided to drop an Injector... No way It can be sorted by tomorrow at 8am.

First engine problem I've had, at the worst possible time!

 

My dad's RX8 it is then for the track day...

I suppose, the next question is does anyone have an working Injector that I could have for a small fee? :)

Sure the injector itself is faulty? Not the connection?

I have ohm metered the Injector, and get nothing, but do get a pulse from the connector incomming

How do you mean you get nothing... You get a resistance of 0? Silly question but is it clean? Or is it green?

Yep, the Injector gives no reading, it's open circuit. The contacts are green, although I have cleaned the contacts to try and get a reading, it seems to be a well gone!

oh dear...some are easier than others, they can all be done without removing the plenum with some modifications though.

I have a good tested one for £30 inc delivery

Cheers for the offer Baz, but I think I have one sorted. Will let you know how I get on with the 'dremel method' of changing an Injector.

I had to do that on mine but ended up using a carbide cutter in a drill as the dremel just wasn,t beefy enough and was taking forever , suprising how deep a notch you can put in the plenum without any worrys of going through . A good tip is to make a pipe up from a hoover and have that sucking the swarf up as you grinding , save alot of mess and possible contamination getting into the injector hole as you remove it .

A good quality screwdriver for the injector screws and give it a good tap with a hammer , helps em crack lose ! HTH :biggrin:

Dremel method worked perfectly to get the bolt and cap off the Injector, but got to go and get a selection of mole grips to pull the bloody thing out. Any advice other than get some good leverage and pull straight up? Soaked in wd40 a few times to prepare.

 

On a side note... The track day at Goodwood was excellent yesterday, even in my dad's RX8, we both thoroughly enjoyed ourselves and I think we're hooked!

iff your replacing the old with new then just grab the basted with vice grips and pull:rofl::rofl:

Got the injector out yesterday after buying some new long nose mole grips, always handy to have! Hopefully the installation of the replacement goes just as smoothly as it has done so far! I want to say thanks to Terry for the kind offer of his spare Injectors!

make sure you've got all the bits of alloy out before you replace the injector. Dont want to be having a thread about having cuttings in the pistons.
