    If it is worn,replace the distributor cap,yes,but make sure the rotor button is pointing at number one spark plug wire,and clockwise place the wires on accordingly 18436572,and then try,if it back fires,then the wires are on 180 degrees out.in other words,re- do the wires on the cap,starting with number where the number 6 wire is ,pull all wires back off and start there,it will be directly across from where the number one was,this would be 180 degrees out.I hope I explained this to you where it is easy to understand,it is not easy to explain.

I have been asked many time for diagrams for a 1994 chevy suburban K1500 I thought it would be helpful to post them on tips and tricks so it could be more accessible to everybody.
Firing Orders
To help out. As you take off one wire to replace it. mark the wire with some tape so you can easily identify were it went. You may also want to look at the diagrams below and look at how your vehicle and make sure that someone else has not by accident switched a wire on the engine.

look at your distributor cap while standing on the driver's side of the vehicle.
Start at number 1, which is labelled on the cap, and go
clockwise

Good Luck
