I thought I had a bad injector on #3. With the motor is running, when I pull the lead to #1, #2, or #4, the engine stumbles as you would expect. If I remove the connector to cylinder 3, however, nothing happens. Even though I was getting a decent spray pattern when I pulled the injector out, I decided to replace the injector. Still nothing. There IS spark at the plug. And my noid light shows that there's electrical pulses at the connector lead. (IMG:style_emoticons/default/blink.gif) On the back of the block, under the air cleaner, I have three pairs of white wires that are solidly grounded.
Any ideas fellas? Thanks |

to make bang, you need spark, fuel, and compression all at the right time.
Does #3 hold compression? Zach |

I don't know for sure, Zach.
I suppose I can find a gauge and test it. |
