4g93 died randomly......electrical help please

[nonickname]

I have a 02 ce lancer stock manual non turbo with 150,000ks and full mitsi history. This is ment to be my reliable work hack It died on me monday night. I was giving way at an intersection, all clear go to cruise off n got about 3 metres n lost all power to engine. It probably wasn't even doing 2500rpm when it went. It wasn't violent and no odd mech sounding noises. The car still cranks and battery has good charge. Ive done some checks and found that I seen to have no power coming through the loom to cyl 3 and 4. Its not the coils as i have spark on 1 and 2. Switch the coils and have the same result. Anybody come across this before? Ive tried lookin on google but not found anyone with the same problem. Im thinking crank sensor or ignition module? Im at the stage of getting a tow truck n forking out th $ for a mechanic, but just trying my luck here as last resort. Any help much appreciated, Thanks

Tell me that bit again?
If you swap 1-2 with 3-4 you get spark on 1-2?

1-4 are on the same coil and 2-3 are on same coil.
So if 1fires but 4 doesnt it is leads or plugs on 4.
Same as 2-3.

Sorry i should have said the set up. it has coil on plug from factory. 2 has a coil diectly on top that has a lead going to 1. 4 has coil on plug too with a lead goin to three. It had no spark coming from the coil on cyl 4 or th lead goin to 3. I switched the coils over them and still had the same issue.

So you changed the coil from 4-3 over with the coil on 1-2 and still had no spark on 4-3.
So both coils probably work fine.
Probably tha crank sensor is ok.
It maybe the ignitor.

i'm going to cuncur with jack and say it's the ignitor also it should try and run on only 2 sylinders so check that your getting an injector pulse for fuel

Did someone delete this link I sent or is my connection playing up?

Follow this guide↑
There is no ignitor in your system. Sorry. Happy hunting.

Hey bud, my mrs had the same thing in hers, 2 things it could be are fuel pump, or alarm/ immobiliser

Crank angle sensor?

 

[4piknup]

Bad cas will cut all spark.
Bad immobilizer will cut all spark not just 1 coil

I think it should run (abeit badly) on only 2 cylinders

Its off to mitsi soon so we will all know next week Will keep you all posted. Thanks for your input.

Im calling $650 to fix and undisclosed multiple problems.
1 stubby buy in, closest wins.

 

[BYBY5L]

surely wont be that much, but then mitsu... dunno i reckon $400

 

[4piknup]

Thats what I was thinking.
I hope its a $50 fix with a loose plug or something. But I wouldnt put a stubby on it

 

[nonickname]

Verdict- you are all wrong. Broken camshaft! Yep. Gone up front by the pulley belt still intact, still turns over freely. $1050 fixed on fri. Th guy reckoned tensioner was too tight when cambelt recently replaced at snother workshop. Shit ay?

 

[4piknup]

Well there you go.
Great it is fixed up now.

Btw 650 + 400 is $1050....

 

[khubner1]

Wow never head of a camshaft snapping on a regular vehicle

 

[BYBY5L]

lol jack, guess i owe you a beer,
yea i cant say I've heard of a cam snapping! Wow, so how'd the tensioner get so tight?
Are they a hydraulic one?

 

[4piknup]

We will go halves in a box when we catch up. But I get 13 and you get 11. Cheers
