Question about 1995-1997 Chevy 1500 Truck Ignition Starter Alarm Switch
WHAT ABOUT THE FIRING ORDER 98 CHEVY SILVERADO 5.7
The firing order is 1-8-4-3-6-5-7-2
The distributor turns clockwise.
Sitting in the drivers seat, the left side of the engine has cylinders 1, 3, 5, and 7. Number 1 cylinder is at the front left.
The right side of the engine has cylinders 2, 4, 6, and 8.
You need to set the distributor in the engine block, when Number 1 cylinder's Intake valve has just closed. The piston will be at TDC then. (Top Dead Center)
To do this, make sure the distributor connector from the wiring harness, is not near metal. The black connector that clips up on the side of the distributor. There are three female blade connectors in this connector. You are going to turn the engine over, and don't want the red hot wire to short out against metal.
Remove Number 1 spark plug. No dangling neck chains, or any other jewelery that could accidentally get caught in the fan. (Thanks for letting me say that. I feel better now. I want you to be safe!)
With someone in the vehicle, parking brake on, and their foot on the brake, put your fingertip over the Number 1 spark plug hole. You want to try to seal this hole with your fingertip, the best you can. have this person BUMP the starter over. Watch the harmonic balancer down on the crankshaft. There are lines on it. Look for the line that has 0.
When the Number 1 piston reaches TDC, your finger will be blown by air. Look at the harmonic balancer. You need to turn it back, (Towards the right side of the truck) until it is at 0.
Now you have to slide up on top of the engine. Take a flashlight, and peer inside. You will see a shaft way down in there. This shaft has a wide slot in it. This is the Oil pump rod. You have to take a long, large, flat tip screwdriver, and line this slot up.
This slot has to be lined, up to the tang on the bottom of the distributor. Distributor cap off, the rotor needs to be pointed to 6:30
Straight at the front of the engine. When you set the distributor, however, you'll note the rotor turns, as you set the distributor down in, when it's close to the engine block.
This is because there is a helical gear on the distributor, and one that matches it, on the camshaft. When inserting the distributor, the tang on the bottom of the distributor shaft, needs to be set at about 6:25 or so, so that when you set the distributor, and it turns, it will line up with the slot in the oil pump shaft. (Fun stuff, huh?)
DON'T bump the engine over until the distributor is set correctly, and the distributor base clamp is on, and tightened to a light touch.
You want to be able to turn the distributor by hand later, but don't want the turning over of the engine, to turn it. Just lightly snug on this base clamp.
Start by putting Number 1 spark plug back in. Number 1 cylinder should be marked on the distributor cap. Lightly set the cap on the distributor until it's lined up. Then bring it straight up, and see where the Number 1 tower in the cap, lines up to where the rotor is sitting. You want to start, by having the rotor just a little before Number 1 tower on the cap. Turn the distributor until it is.
Install the distributor cap. Make SURE all clamps are in position, and the cap is seated flat, and correctly. Failure to do, so will break the cap, rotor, and may cause further damage!
Put the spark plug wires on the distributor cap, one at a time starting with the Number 1 spark plug wire. Go clockwise. The next tower is Number 8 spark plug. That's the one on the right side all the way to the back. Then 4, 3, 6, 5, 7, and 2.
