Distributer cap need to know the setting on it

You have to take the access panel off inside the van. There used to be two screws on the outside under the hood and the two clips inside that have to be released. Mine was older so I don't know if they are the same. Find the wire that is going to #1 spark plug. The is the spark plug at the very front of the drivers side. Mark the wire and its relationship to the cap someway. Mark all the other wires in the cap so you know their location when you put the new distributer in. Or leave them in the cap if you are going to use the same cap. Take the cap off and turn the engine over so the rotor is pointing directly to the #1 wire. It may not hurt to make some other point of reference, where the rotor is pointing to. Loosen up the bolt at the base of the distributer, blow all dirt away and turn and pull up slightly on distributer. Do not crank engine at any point during this time until the new distributer is in. Once you have it loose take the bolt out or at least slide the clamp all the way out of the way, Remove the distributer. Remove the base gasket for the distributer and clean the surface and put a new gasket on. Put the new distributer in paying close attention to where the rotor has to line up. The point of reference I told you to make earlier. You need to turn the rotor slightly CCW from the reference point as it will turn CW a little when it is mated into the cam gear and seating to the motor. If the distributer will not go in where you need it, it may be possible that the oil pump drive has moved a little. You may need to get a long screwdriver and go into the distributer hole and turn is slightly. After you get the distributer in, you should be able to put the cap back on. Or put all wires back on to the same positions that I told you to mark earlier. If you followed this closely then the engine should start. It should probably be timed. Please rate my answer so I am rewarded points for it.

You need to determin which direction the rotor button turns when the engine is running. Take the cap off and get someone to bump the starter . Watch the rotor. If it turns counter clockwise the fireing order will follow its order counter clockwise on the distributer .In other words # 1 wire on the distributer goes to # 1 spark plug. Then the next wire counting counterclockwise goes to # 3 plug . Follow the firing around the distributer for all the wires. counter clockwise is the oppisit to the rotation of the hands on a clock .

take the spark plug out of the #1 cylinder and turn the engine by hand until the piston is at the top dead center of its stroke (put a screw driver in the hole and you should be able to tell when its all the way up). now pull the cap off the distributer the rotor should be pointing at the #1 cylinder wire. if not then the distributer is in the wrong possition. remove the distributer and point the rotor in the correct possition(#1 cylinder) and place the distributer back in.also if this is a used engine replace the cap,rotor plugs and wires.the truck should start. Hope this helps you out.

the coil is in the distributor cap,,

Standing in front of the truck, #1 is at 5 o'clock on the distributor and it runs clockwise.The firing order is 1-8-4-3-6-5-7-2. Hope this helps.

You can rotate the engine until #1 piston is at top dead center when it has the rotor on the distributer will point at the #1 on the cap.

Wires just pull out of the top of the cap. Do them one at a time and you won't have a problem putting them back.(they just push into each hole.)

go to this link for diagram. one is white spot on distributor cap.

TDC stands for Top Dead Center, however it is only to set the cylinder number ! at TDC, if yu know where the timing marks are align the crank pulley mark to the "0" of the timing mark, usually this can be achieved by setting the crank shaft doel pin to twelve 0 clock position.
