Put yur old ones back in see if it fixes it

mucka

It struggled to fire with those also, it did idle but very lumpy and hardly any revs, iv brought those boah 4 from halfords surely it wouldnt be plugs would it

mucka

Check light doestnt come on with ignition n when im trying to start, only const flash when i use the 2 black plugs

you have got the ht leads going to the right plugs??

mucka

Yeh im sure its the cream plugs at front of car, and black plugs for rear, as i got individual coilpacks , is that right

micky boy

iTrader: (10)

just put your old plugs back in and confirm you have got the plugs on the coil packs properley because if they are not it will cause it to misfire

mucka

okk will try that, mean iv tiightend bolt as gppd as it can really

micky boy

iTrader: (10)

the bolt is there to hold the coil pack to the heads, but i know of people who have not put the plugs on correctley and it wont start. but definetley check the spark plugs or put the old ones back in as it was obviousley ok before

mucka

Will do , hope it sorts it out not owned long, seem all problems,

I've had this problem with the bosch 4's my car wouldn't start put a set of ngk's in and it fired first turn of the key. I put the bosch 4's into another impreza just to be sure it was the problem and that wouldn't start either but as soon as i put the original plugs in it started first turn of the key. And yes the plugs go black to back cream to front.

mucka

I done the old test with a coil out and put a old plug in and ground it on block, couldnt see a spark

micky boy

i know its a stupid question and you may have done it but have you armed and disarmed the car to deactivate immobiliser ????

wouldnt use bosch plugs mate hd prob with them in past."2sets" have u not readur codes seeif that flashes any info

mucka

@ micky boy- yeh iv tryed that still no joy.

And the any codes what was up before all this was 22 knock sensor and seemed to missfire, but fitted new. so i brought bosh plugs as i thought they was good try and start and just keeps cranking no firing.

But no check light on while im trying, but connected black plugs and just flashes constant.

Thinking mite replace crank sensor??

mucka

And fuel is all ok, did put 95 in though souldnt be problem though should it

95 wont stop the engine from starting. if you have a multi meter give the crank and cam sensors a test. put the probes on the connectors and wave some metal close to the front of the sensor. put it on 2k ohms i think and you should see a fluctuation each time the metal passes the magnet. cam sensor should come out easy, the crank is a bit more of a pain. you could try pulling the plug off the crank sensor and turn over. see if it records a code.

what ecu are you using?

mucka

Ok cool will dig the meter out, and just standard ecu, thanks for that

Spoondanny

do a reset on ecu buddy

Check that the plugs you took out and the plugs you put in are the same thread length as the local subaru garage gave me the incorrect length plugs!!!!

mucka

Ecu reset is that the green plugs? and will check lenghs didnt know was different to be honest, , ill be at my garage tomoro, so will be very busy checking all this , thanks for all your inpuy, top forum....

Spoondanny

plug the green wire in and the black ones tuen ignition on dnt start it tho hold throttle don for 10 seconds and u will hear all the relays click and the fans will come on and solinids etc onced thats done take foot off then start it wait 15 seconds and ecu lights will flash on and off then its done buddy then tuen off dissconnect plugs

mucka

Ok sounds easy enough, i mean anyone fre over weekend, and wants to help

mucka

Right after messing about, pur old plugs back in , now hav spark, but it seems to be everywhere , sometimes i get spark to the old test on the block on each coil, then one coil will go down, and keep swapping.

like... 3will work, passenger rear want, then it will, and then drivers front coil will go down...

checked conections like 5 times, and ok, whats going on ???

Tryed to get crank sensor out but solid in and dont want to break, incaae i cant fully get it out

scoobyricht

If you are now getting spark then crank and cam sensors are working, how well i dunno but the ecu is getting the signals so allowing spark. How good is your battery? did it manage to fire up and run for a bit?

mucka

Charged battery most of the day, and its not very old, no couldntnt get to run, for split second though does sound like it was to run ;(.

Maybe new sensors...

scoobyricht

iTrader: (4)

If its getting fuel, is sparking and has compression it should run, or at least fire... are the fuel lines connected the right way round?

mucka

Just had aa out, they said it fuel issue, ran on easy start, and he checked everything, putting in garage tomoro to get sorted

mucka

All is firing ok now, petrol all nice , was told there was a blockage in lines any letting bits of fuel through.

thanks everyone for your input, and hope to meet up on a meet oneday.
