Cylinder not firing

[Brick]

i have a ae92 4agze and the #2 cylinder wont fire
we hav changed sparkplugs, leads and coils but still missing.
we hav also checked compression and all is fine and yes it is getting fuel but it just wont burn

any help will be good! got to get to timaz tomorrow

Dizzy?


Only time that's happened to me is when something in my 3sfe smacked the end of my sparkplug (valve I guess... meh, I thought they were made to rev at 8k)

What is the compression running at?

[Brick]

i wasnt the one that checked it, my mate did and said it was all fine

[Alycia]

Well I talked to my uncle for you and he said it should be at least (Off the top of his head) 130-150.

He said theoretically if you have checked all of those things and they are fine then it should go.

Are you getting spark in the cylinder

[Brick]

i dont really no lol it was hayden that was sorting it out, i might take it back to him tonight

[Malcolm]

had this problem on a mate's st165 after we swapped st185 engine into it. Engine was running fine in the old car, then in the new one one of the cylinders wasn't firing

Turned out to be a blocked fuel injector...

Turned out to be a blocked fuel injector...

Thats what I was thinking, if its getting spark and good compression it must be lack of fuel.

checked all the leads havnt broken at some point ( i knw they are knew but i managed to snap one, dont ask how) use multimeter.

other than that, nothing else i can think of that the others havnt said.

[Malcolm]

other possibilities would be fuel injector not opening, due to a bad contacts on the plug, broken wire, or damaged ECU (unlikely to affect only one)

[flygt4]

i had a loose injectors plug make it miss on one cylinder. check all the connections and all fours said.

[l1ttle_d3vil]

test the ohmes on all the injectors, make sure they're all reading what they should be. is the spark plug wet or smell strongly of fuel after you've had it running?

[Alex B]

pull the plug out and see if its fireing...

[Brick]

we will be having another look at it tomorrow
it is getting fuel and air, but not suer on sprk
so hopefully the coils we got will work this time

[Lloyd]

Its a twin coil isn't it (not sure if they all are or not). So if its a coil fault it would be running on 2 instead of 3 being that its a waste spark design...
