replacing Injectors on Opti

Nick Hearne · 30 July 2005, 14:13

Hi, can anyone advise, I have a wonning light on the Opti max which I have been told is that no. 5 injector is at fault!
I was told that it is OK to run but the only way to clear the fault is to replace the injector

It dose run well, although I have only run it in this condition so I have not way of knowing if the new injector will make any difference to the performance!
So I have asked the chaps how fitted the outboard to fit a new injector, no problem Just anther £160 + fitting

BUT you will need new O rings & these only come in sets for all 6 injectors at a price of £70 odd squid

What is so special about thees O ring to cost soooo much

It has been suggested that now the engine has had a good thrashing that it could have unstuck the injector (if that was the problem) & if it was reset it would not come up as a problem

Any ideas from any one?

Sad to read about this new problem and your service center is not a flexible one. According to my source you should not worry to much as the onboard computer is not to allow you running on full power but surely giving you enough power enjoying it in the meantime.

PM me serial number of your engine and I will see if we have injector on stock and surely we have the O-ring and you will not need to have the full set.

I expect to be going on police exhibition in fortnights time (somewhere in midwest or Wiltshire) and could bring it over myself then.

Hi Nick,

I had an injector fault warning come up on my engine a while back - although it didn't specify which one.
It turned out that one of the plugs had come loose - I just unplugged each one in turn, gave it a spray of WD40 and put them back on. Problem solved.
At the risk of sounding patronising have you tried this yet?

Me too you do need to get it sorted out as it can cause predetonation . In my case it was a corroded plug on the injector. Ignore Optimax warnings at your peril!

Duncan after you did this did you not have to get the warning cleared by a mechanic?
I have been told by the mechanic who fitted the air Temp sensor that the fault that is causing the light to come on is because there is something wrong with no. 5 injector & the only way to clear the fault is to replace it!

Well this saga continues!

It was not the fuel injector but the air injector!!!!

So I'm now having this replaced!
So far this year I have been out for 5 days only on the boat

Lets hope for a Indian summer!

Nick if its any help to clear the light- disconnect the battery and reconnect - which should serve to reset the ecm.

But I will still have a fault so will it not just come back on?

sorry - thought you had found the fault??
I had a similar problem with the injectors on my Kia - because I put some 10 liters of methanol instead of petrol into the tank.The check engine sign came on - and KIA told me that no 5 was misfiring- drained all the petrol out , put in some good stuff and a bottle of fuel injector cleanng additive. The engine was then running pefectly but the light was still showing ( quite logically) as the ecm had to be reset and 9 times out of 10 you can do this by taking off the + lead at the battery and putting it back on.

I am giving you this rant as the problem seems so similar to my engine. With all the muck sitting in rib tanks and condensation,unless you regularly check and change the filters - the injectors get a real bashing..

kind regards
