-----Question-----
Wil,
Car won't start. Timing light shows spark. Ignition timed to 12 degrees. Timing belt is aligned to marks on cam pulley and tdc at flywheel. Code shows rich condition, no other codes set, check engine light not on. Compression between cylinders varies from 110 to 135. Fuel pump and tank replaced recently. With air cleaner removed it appears the injector is spraying an excessive amount of fuel. Problem began at last startup when engine ran poorly with a loss of power and excessive fuel spray at about half second intervals that increased to slightly shorter intervals at higher rpm. Loud noise similar to a leaking head gasket when injector pulses. Any advice will be appreciated.

More than likely you need a fuel injector.Easy to replace.

Wil, I have installed a new fuel injector but no improvement. The engine will run poorly and still pops thru the intake manifold. The popping stops when #2 plug wire is disconnected. I installed a new plug in #2, a new pickup in the distributor, a new rotor, and reinstalled a wire set and cap saved from the last tuneup, but with no improvement. The compression on #2 is 120 so I believe the valves, rings, and head gasket are OK. Since the intake and exhaust manifolds are on the same side of the head, is it possible for #2 exhaust to somehow leak into the intake manifold? Any other suggestions? Thank you.

Sounds stupid but are you sure the firing order is right?And did you line the distributor up correctly.It sounds like the spark is firing when it shouldn't,plain and simple.Do you know how to check cam timing?You will need a timing light with an advance knob on it.You are disconnecting the coolant sensor when you set the timing,RIGHT?OK so use this timing light,look at the timing mark,turn the dial on the light until the mark is at 0 then take the light and aim it at the cam sprocket.The oval hole should line up with the rubber tit (for lack of a better word) at the top of the valve cover.If not then your cam timing is off.
---Question---
Wil, Timing checked out OK, so I removed the valve cover. The #2 exhaust rocker arm was out of position. How do I put it back into position, does the camshaft need to be removed or is there an easier way? Should I check anything to insure that it does not happen again? Thank you for helping!
AnswerWelp I guess you found your problem eh. I don't know how you could have proper compression like that.Turn the engine so that the cam is in the closed position in that cylinder.You should be able to forcably push and pry that rocker into place.You can push down on the valve but don't push on just the cap or you pop a retainer out.And that would be a new nightmare.I have always been able to do it this way.
