miss fire and won't start .
« on: January 01, 2010, 10:45:08 pm »
Well i got abit of a problem here .

my 2g Eclipse wont start no more the engine is a 4g63 turbo ..
the ignition and spark gradualy   start failing piston by piston i was down to 3 then  2 and now only one seams to be firing when it turns  over to start there is no Spark  at all in 3 of the 4 cylinder wich makes me think of an electrical problem .. heres the list of things i have changed thinking it may help with out success  , spark plug and wires , coils , tansistor/egnition module , and Crank scensor .. I am running out of  ideas of what could be wrong with it , John  told me to  do a compresion test and so i will do  when i get  a tester ,

im throwing that out there and see if anyone else had a similar issue and point me  the right direction to get my baby back on the road .

cheers and thank you .

do you have a 7 or 6 bolt? do you have a cam angle sensor? how bout a code reader... try scanning it and see what codes you have.

Go to canadian tire, buy a code reader, read your codes, return the code reader.

they are not that much money and if you have an OBD2 car of any kind in North America, you may as well keep it.  Reading 1 code(or at the most 2) it will pay for itself.

Also, where is the car at right now?

I MAY be able to swing by and have a quick look.

says he changed the transistor/ign module, so I am assuming thats the same as the ignitor?

make sure the cam angle sensor is instaled correctly. It could be 180 degrees out

that will USUALLY only cause a slight barely noticable misfire.  many people have driven around for months and years with it 180 out.

Plus his used to run good, and just started to go like it is, without him taking the CAS out of the car.

sorry thought he allready replaced it. I have never run with it 180 out so I wouldn't know how it would affect the car, but for the 2 easily acessable bolts it would have been a easy check. Just tossing ideas.

Check b+ to PCM with a test light for voltage. Use a test lamp that has 1 amp or more of current draw to assure that the wiring is capable of good current flow. Some of the newer test lights only have a current draw of 50 milliamps or less. If your test lamp has less than one amp of current draw, then a turnsignal bulb will make a good substitute.
