    Vaccum Lines

    I could use a diagram of all vacuum lines on an 87 TBI if someone has it. Most all of mine are plugged with caps. Thanks

    Starting issues

    How have you verified battery has plenty of juice? Check your grounds and connections on starter. However, if were that, it should do it all the time and not start perfectly when cold. How old is the starter? Have you had it tested?

    87 to 94 5.7L?

    So I went and picked up an engine at the salvage yard. It is out of a 94 Sierra. The guy said it would work, but now that I am home, I am not sure about how the wiring is all going to hook up. Did I buy the wrong engine?

    2nd Square Body

    Yea, I could not believe how straight it is. I have only found two dents. One on the hood where I bet they always hit it to pop the hood and one small one inside bed. It doesn't look like they ever hauled anything in it. Still original seat cover and cushion, not missing or ruined foam.

    2nd Square Body

    I had an '86 about 15 years ago. Picked up this '87 last night for my 14yo son. He has exactly 2 years to get it ready for his daily driver. Bought for $300 with a thrown rod and no transmission. Now, where to I find the original paint color/interior color/model codes and a decoder?
