| − | If all else fails try this | + | Often the intake manifold runners will be numbered to show the firing order. If all else fails try this: |
| + | *Remove the #1 spark plug. | ||
| + | *Remove the distributor cap. | ||
| + | *Put your finger on the spark plug hole that you just removed and turn the engine over slowly. Do this until the compression stroke comes up, you will feel air pressure at this point on your finger. | ||
| + | *Look at the timing indicator located on your timing chain cover. You should see a line scribed in the lower crankshaft pulley. | ||
| + | *Align the TDC line on the pulley or damper outer ring with the timing tab indicating "0" or TDC. You now have top dead center. | ||
| + | *Look at the rotor. It will point to #1 on your distributor cap. The wire that plugs into this terminal in the cap can be called #1. Connect the other end to the spark plug on the driver's side front. Continue by following the direction of rotation to attach the remainder of the plug wires following the firing order. | ||
