Customer: I am trying to help a friend of mine get his pick-up operational. It quit on him the other day, and being a ford owner all of my life, I am not familiar with these vehicles. It is a 1994 GMC Sierra 4 x 4 extra cab with a 5.7L motor. Before we towed the vehicle to my house, there was another gentleman that was adamant about replacing the cap and rotor. Before I could get a picture of the distributor cap, wires etc., he unplugged all of the wires and took the cap and rotor out. He moved the distributor while unplugging the wires. So, now I am starting over. I am trying to align the crankshaft to zero degrees TDC on compression stroke, which puts the rotor facing towards the number one cylinder, and then I attach the plug wires in accordance to the firing order, and that should be it. However, with the distributor being moved, I am not sure how to align everything to get it to where we can even start it. We have spark to the plugs. I have also read about at wire that needs disconnected behind glove box. I don't know if that made any sense, but it doesn] t to me either. Thanks for the help, and sorry about the confusion. Just trying to help a friend out.
JA: Thanks. Can you give me any more details about your issue?
Customer: The pick-up died while towing snow mobiles, and would not start. At that time, he had spark at the coil, but nothing to the spark plugs
. We now have spark to the spark plugs. It tries to fire every now and then, and I retard and advance the distributor in hopes to get it running so we can time it accordingly after. But, I am not sure how to ensure I am at the correct setting that aligns the TDC, the rotor, and I believe the number 1 plug wire on the distributor cap. I also need to know if the wire that is referenced under the glove box needs to be unhooked before it will start and can be timed?
