Question about 2005 Pontiac G6
Obd2 scanner reads dead cylinder #2 dead injector#2 alarm goes off randomly now cruse control does not work either check engine light blinks and sometimes stays on rough idle and third brake light stays on after turning car off. HELP!
Use a digital volt meter,put it on the ohm scale check number 2 fuel injector should be 11 to 16 ohms if not reads zero fuel injector faulty.if numbe 2 fuel injector okay.use noid light hook it to fuel injector electrical connector with fuel injector disconnected and see if pcm is firing the fuel injector noid light should blink when cranking the engine.if light steady pcm not firing 2 fuel injector,if noid light dont light up.there is a open in the wiring connector 2 fuel injector 2. if fuel injector okay,check spark plug, carbon foul you have a bad ignition coil or wire if you see oil on spark plug you have worn piston ring or leaking valve guides allowing oil to foul out spark plug.do a compression test check compression to see condition of the cylinder.

Check the ignition control module. Sounds like the exact same problem I have had with mine. Took it to the dealership and the were able to tell me right away. The ignition control module is very easy to replace and is located on the top of the valve cover. Hope this helps!

Most consumer available scanners read OBDII on 96 or newer vehicles. If your car does in fact have a OBDII plug then all you need is the software in your scanner to be able to read OBDI codes...a 95 is running OBDI. Advance Auto or Autozone might have a OBDI compliant scanner for free...just tell them you have the OBDII port so they don't take up all your time digging for the adapter!

It sounds as though your Crankshaft Position Sensor has gone out. They are pretty easy to change. You will have to remove your harmonic balancer/crank pully to get to it, as it is on the inside of the pully. Also, if you have a 3.1 engine, you have a second Crankshaft Position Sensor on the side of the engine closest to your firewall. (it is below the number 1 and 3 spark plug). It could be that one or the one behind the balancer. I would suggest replacing both of them at the same time. As for removeing the harmonic balancer, you should use a puller to do so. When reinstalling it, do not use a hammer or anything to tap it back on, as this can damage the balance and also the crankshaft. You should use a harmonic balancer installer to put it back on. Both the puller and installer can be borrowed from Autozone (with a deposit that will be returned once you return the tools).

when u bent the push rod u might have bent the valve in the head ,by puting the longer push rod where it didnt belong it kept the valve open when the piston came up and the force of the piston on the valve bent the push rod,you will have to remove the head,hope this helps
