Well here goes. As I'm posting on the "New Members Group" page I'll start with a short intro. First, I'm Darrel and live in SW Missouri Also, I'm an ever-evolving shade tree mechanic who's worked on everything from lawnmowers to diesels. Recently, I purchased a 89 S10 Tahoe long bed 4.3L TBI as a retirement project and am looking forward to learning all I can. She's apart and doesn't run yet but that's my first priority to get it purring. As she's set for a while I'm always find stuff that needs fixed. Anyway this is my first 4.3L and my first dealings with TBI so I've a steep learning curve. One of the things I've come across is timing. Now it sound simple enough but everything I read tells me to disconnect the EST. What I've read is that its a tan wire with a black stripe and the disconnect ins either on the firewall or under the dash on the passenger side. I've searched high and low and can't find any disconnect. However, on the distributer, there is a 4-wire connector and one of the wires if tan with a black stripe. Therefore do I unplug the 4-wire connection or am I missing something? Finally, sorry for the instant problem, but I'd appreciate it if someone would point me in the right direction.
