I have a 1999 baleno 1.6 efi engine in my sierra
I cleaned down the engine as it was dirty now it's running on three cylinders
Buy the sounds of it

What I have tried to fix the problem

New coil packs
New leads
New spark plugs
Done a compression test and all cylinders are putting out the same

The only thing I came across when I unplugged one of the injectors it didn't change
The idle of the engine... But the other three did

Any one have any ideas

Water in spark plug area.
Plugs not connected right
Check Coil wiring plugs

Have you got spark on that lead at all?

I can't think of anything else right now although if you definitely have spark on that cylinder and no firing then maybe the injector on that one is crook?

Too late/tired/pissed to be of more assistance right now.

Was it running properly at all?

EDIT: By crook I mean blocked/dirty/unplugged e.t.c. not just broken, check lots of stuff, think about what you need for it to be working and see which of those things is missing.

If you suspect an injector, try a bottle of injector cleaner in the tank.

Did you pressure wash it, maybe you blew off a wire somewhere.

Water problems often dry out themselves, but there are good dewatering products that don't short out electrics.

If it was running fine prior to washing it then it's probably some water in a connection somewhere. You could let it dry out or blow some compressed air into the connections around the engine bay.

It's has been a week since I washed it and
I've pulled the connections out And gave them a blow with air

[BlueSuzy]

have you looked down spark plug ports?

[supa_slim]

I've put new leads. Coil packs and plugs
After it started to play up
So they should be fine

[Teracis]

Fark I'm half pissed now but clearly that's better than tired and pissed from last night.

You would laugh but once upon a time my ex washed the engine of her car and then it wouldn't start next time she tried to start it, after checking a few things I pulled a plug to check for spark, hmm no spark, wait a minute, the freaking coil lead had popped off but not far enough to actually come off the coil...

Check everything meticulously one thing at a time and you will find the culprit.

Good luck and don't forget to let us know what it was!

EDIT: and when you say I've replaced this and that it should be fine, check a second time and have a really close look, you wouldn't be the first or the last to overlook something tiny like my example above because it looked ok on first visual inspection.

Going to take the front clip off tonight so I can see every thing
And go over everything twice i bet it will be somthing littlle like on wire or a loose conection

[alanbie]

Well, if you plugged out 3 injectors and it affected the firing of the engine and 1 injector didn't, a check of that injectors wiring and failing that, replacing the injector would be a good place to start?
You could have blown a fuse somewhere as well so check all those as well.

it ended up being a broken wire

So you didn't check the wiring.

[supa_slim]

checked it after i found out it wasn't getting power to the injector
