Miss fire
 

Lads just last week found a 1993 import wrx that had been dry stored for 11 years non runner but not a drop of rust .I got her started with a new tank of fuel and fuel filter changed all the fluids plugs coil packs put a wide band sensor and boost gauge in change all the vacuum lines went to give it a test drive as it idled fine Then disaster she miss fires like a crack head with an ak 47. First thoughts we're check the timing done this and it is on point am not sure we're to go next Tried her with and without maf cleaned throttle body and idle control Would it be worth a compression test b4 I check the injectors/ecu she idles fine if you tap throttle hard she revs fine holds boost but if you slowly apply throttle she pops and spits ?? ? ? Pluss the starter and alternator failed the 3rd time I started her

Electrical fault???
 

Could this be an electrical fault as she has only done 70 k with proof

check for post maf air leeks

I'd take the coilpacks out and check those if they weren't new ones u put in. Those old coilpacks are always breaking down.

Also, if you've changed the vacuum lines u might have whipped out the one with the restrictor pill in it, worth a check

Coil packs . . .

I put new coil packs on and new plugs. Removing the pill wouldn't cause a miss fire surly when I get home today I will remove the plugs and check I Havant cracked one I will let you know if I have any luck today

New, or new to you coilpacks?

Check to make sure they are actually seated right on the plugs.

What plugs did you fit, and has the car got a decat exhaust?

I found a broken wire for cylinder 4 coil pack after tracing it into the loom but don't want to go any further untill I put the new cam belt pulleys ect on i should get it done tomorrow if the rain stays away. I used brand new coil packs. And cheap 30 pound plugs as spent 160 on packs lol

from that photo the crank looks 2 teeth out clockwise

So that arrow should face the vertical mark? There is a notch to the left of that witch Is lined up with the red mark some one has left ?

yep and the red paint/loctite is also on the idler, could it be just finger marks, but i still recon its 2 teeth out, cams are spot on

Just gone throw 100 photos I think the arrow should be 3 o'clock ? Or is the different for my ej20.

The arrow is NOT a timing mark. The pulley looks ok to me. The pulley should have a painted mark on it that is a timing mark

Looks like you might be right.
Look at the last post on this page

Right new cam belt ect fitted cheers john. put all the front mount inter cooler pipes on started a right treat sounded perfect then turned her off after a 30 second run just to triple check all looked good went to fire up again but now she just turns over FFs will it ever end lol. I took out the crank sensor and noticed a dent in the bottom am sure this is my problem. I can only find ones that have a plug on the sensor it's self mine goes all the way to the throttle body b4 you can unplug it any ideas were I can get a new one ?

Also I need an alternator. I removed ac pump and pipes today saving weight gaining room what should I do with the connectors ?
