Need a diagram on the distributor cap for 1992 gmc sierra 4.3 so i can know where number one is on cap and how cap sits on distributor

Remove the distributor cap while cranking, see if the rotor turn. If not then the distributor gear is worn (need to replace the gear).
The ignition module could defect. Need to check the ignition module for power and ground and a bypass signal at the module.

Hope it helps.

if you know the firing order, then get #1 on TDC, and then take the cap off, the rotor should be pointing forward, thats where number 1 wire should go.

Here is a firing order diagram and note the distributor cap latch positions between terminals 1 and 2 and 5 and 4, and let me know if you need any help to understand this diagram or if you require any further assistance.

Sits in the ignition distributor, remove cap and two small bolts that hold it in place.

For the 1992 4.3L V6:
Firing Order:
1-6-5-4-3-2
Cylinders:
...(back)
6...........5
4...........3
2...........1
...(front)
Distributor:
.......(back)
(+).....4
..................3

......................2

............1.....(+)

Let me know if this helped or if you have additional information or questions. Feel Free to contact me at FixYa.com!

I don't know about a diagram. Just buy some 1/4 inch brake line and run it as close to the original as you can.

The GMC 1500 Sierra have several engine sizes, hope this helped...

1-8-4-3-6-5-7-2 Distributor turns clockwise Number one should be in the 5 oclock position. You should be able to draw an imaginary straight line between the coil tower and number one tower on the cap and the number one spark plug.
