Just finished buillding my engine and started it for the first time last week after a head and cam swap. Idled pretty good even though timing was off a bit. This was last Sunday. Last Thursday I go out to the garage hoping I was going to set the correct timing. All of the sudden the car would not idle at all. I find a few different problems that were contributing to the factor......low gas and leaking pulsator. With those fixed I still can not get the car to idle correctly. My plugs are almost to the point of being soaked with gas so the program I am running is dumping a lot of fuel, corrected that, but still can not get the car to idle.

Put a timing light on each plug wire and noticed that cylinders 1, 7, and 4 out of 1,3,5,7, 2,4, and 6 that were tested.....were not getting a spark. I know that the following are good:

wires
ignition module
ignition coil
pick up coil

I have a new cap and rotor on the distributor, but something I never thought about has me wondering....is the rotor supposed to make actual contact with the inside of the distributor?

Could the actual distributor be bad or cause this misfiring problem?

I have to continuosly open and close the throttle to keep the car running, any advance to WOT and it will just stall.


Any thoughts or ideas would be greatly appreciated.

Thanks

 

The rotor contact doesn't actually contact the distributor cap terminals. The spark bridges the small gap, jsut as the spark does at the plugs.

Is there any moisture in the distributor?

 

No moisture.
