Only firing on 2 cylinders?
Ok,
A few weeks ago my 2000 Galant 2.4l coasted to a stop on the highway. Towed it to my buddy's garage figuring on replacing the fuel pump.
Did that. Still wouldn't start. Replaced the Cam Position Sensor, still nothing, replaced one of the two spark packs nothing.
Opened up the timing belt cover to discover that the balancer belt had come apart, replaced that and the timing belt, and the crank position sensor. We also replaced the spark plugs too (yes they're gapped properly).
Now the car will actually start, but it will only fire on cylinders 2 & 4 and 1 & 3 aren't firing at all. We pulled the codes off the car and got one for random misfires, nothing else comes up.
Where do we go from here? All four of the cylinders still have compression (125psi for 1-3 & #4 has 100psi), all four are getting spark.
Do we check the injectors on the two cylinders that aren't firing or do we bite the bullet and tear off the top half of the engine assuming that now we've got valve work to do?
Any suggestions would be greatly appreciated, I'm running out of money to throw at this car.
