Ok, so I went out to start my truck which is a 94 toyota pickup, also called the helix, and it would not start. It was not firing on three of the six cylinders. They were all three on the same side, so I replaced the plugs which were black. I replaced the distributor cap and the rotor along with the cable for the coil pack going back to the cap. It still won't fire on those three cylinders. It does not make any sense why it won't work. I would like to know if anybody knows what is wrong with my truck.
