I would hazard a guess that if all the cylinders are showing the same pressure, then I doubt there is anything wrong with the compression. Can't think of anything that would make all 6 cylinders show low readings all consistent with each other, apart from a healthy dose of bad luck.

Or a bad gauge.

I'd be tempted to try it on something else to check if it's ok.

How do you know that an injector has failed? Has it thrown a code?

Mine also restarts with no kill cord. Spare one lives in the console! I'd much rather they were set up this way than be unusable with no cord on board. My old Johnson carb 2 stroke was the same.

Presumably the fact that a 2 stroke works entirely differently from a 4 stroke with valves will mean the compression readings are completely different? I have no idea what to expect though.

I don't know if this is relevant to an E-TEC but a lot of modern automotive engines you MUST NOT pull a spark plug lead off while the engine is running/cranking or there is a very real possibility you will fry the engine ECU. There are dire warnings about this in some workshop manuals.

06 etec 150 compression

gentlemen, thank you and i love the interset but still no answer, the kill cord thing is a good idea as is t merc type, hightower your right that the fact of them being so even and i agree but 60 psi i d always be looking for at least a 100 and i cross ref the guage on another engine and got 110, so it aint t guage as i said, could it be a low comp engine but that low, now too answer t injector question, you ll hear an engine not running right and when you see petrol in the water at tick over and she s burning a gallon yes a gallon every mile you dont need any codes to tell ya there s something wrong, anyway turns out i ve an open nozzle and shes just pumping the juice through, so thats how you do it. thanks

Sounds like crap in the injector holding it open, for it to "fail" in the true sense it would have gone open circuit & logged a code. They can be stripped down & cleaned, though I've never done one. I'm away from home at the mo, when I get back on Friday I can look in the manual & see what the comp figures should be.

Wel, slap my thigh & roger me rigid with a market vegetable! the manual doesn't give any compression figures. I can only find one mention of compression in the whole manual & that's in the fault finding section & says "Fault- low compression. Action- check compression" hardly helpful Looks like it might be a dealer job

How much did you have to shell out for the new injector? I have a number of water damaged injectors on mine that will need replaced, been told they are about 400 + VAT!
