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 |

Coolio, the plug will tell...
Not switched wires if it just happened so that rules out some ideas. |

OK.
Plugs out. On the tan side, and dry as a bone...like no fuel. Checked the spray again... this time nothing. Tried another spare injector, still no gas. I'll swap in a known working injector (from one of the other cylinders) tonight. I can't believe I've got two bad injectors, though. Could the harness have a break in it. The noid light says there is power, though. QUOTE(Dr Evil @ Jul 20 2007, 09:31 AM)  Coolio, the plug will tell... Not switched wires if it just happened so that rules out some ideas. |
