1987 Chevrolet S-10 Pickup - Answered Questions & Fixed issues
I have a 1987 s10.
The three lines hanging under the truck connect to a valve on top of the 4x4 transfer case, this is why the 4wd does not work. As for the throttle body lines there should be a diagram on the radiator support that explains that. You should have one large line that goes to the PCV valve, a small line going to the air cleaner, a small line connected to the MAP sensor and possibly another connected to a valve that controls the EGR valve. Your fifth line should connect to a port on the manifold that supplies vacuum to a tank that is the vacuum source for the HVAC control doors and the front axle engagement system. The axle engagement system is what the line hanging by the transmission under the truck is for.

Ctsy/dome lites remain on dimly when door is closed
Try removing one bulb or the other at one time preventing power completing the circuit if the problem in a light. Those ones are tuff to find but second place I would start is removing front door cils and cleaning out and playing with wires in there to see if you can find a problem, also wires in the boot between door and frame, usually drivers side cause it's used more often.
We are installing a distributor on a 1987 S10 2.5 ltr 4cylender an we were not here when the old distributor was pulled
Take out the #1 spark plug and turn the engine by hand until you feel compression building when your thumb is over the spark plug hole. Now continue turning the engine slowly while watching for the timing mark on the dynamic balancer line up with the TDC mark on the timing indicator. Position the distributor so that the rotor is pointing to the #1 plug wire position on the rotor cap. When you mesh it with the cam gear, it will move past the #1 position. Take it back out and move the rotor to compensate for the distance it moves when the distributor is fully seated. Install the base clamp and bolt but don't tighten the bolt yet. Make the engine ready to run. Hook up a timing light and start the engine and set the timing by rotating the distributor until the timing marks are correct, then tighten the clamp bolt.
