1990 chevrolet caprice is the anyone tat can help get me back on the road?

firing order is 1 8 4 3 6 5 7 2

Driver side front to rear is 1 3 5 7

Pass side front to rear is 2 4 6 8

Rotor/firing order goes clockwise



Remove 1 plug, put finger over hole, have buddy to bump the key so starter turns engine a tad. When you feel air blowing on your finger stop (up stroke should blow and down stroke should suck)



Now using a 5/8%26quot; socket and a pull bar, put socket on center lower pulley/damper bolt and %26quot;tighten%26quot; the bolt that will turn engine over





Turn like that till your line on damper matchs up with the 0 or TDC mark on tab.



Now pull dizzy cap off.



What ever post the tip of rotor button points to is your 1



Put 1 plug back in, mark with marker or paint %26quot;1%26quot; on the dizzy cap in right place



Put rest of the wires on in order of 1 8 4 3 6 5 7 2 clockwise around cap1990 chevrolet caprice is the anyone tat can help get me back on the road?
rotate the engine until the 1 cylinder is at top dead center of the compression stroke (both valves closed and 0 degrees on the timing plate) locate the post the rotor is pointing at. That is where the 1 plug wire goes, continue with the firing order around the cap in the direction of the rotor rotation.1990 chevrolet caprice is the anyone tat can help get me back on the road?
Bring your timing mark on the fly wheel to TDC

Take out the number one plug and make sure the piston is at the top on the compression stroke. You can hold your thumb over the spark plug hole when aligning the timing mark to see if pressure is forces past your thumb to be sure you are on the compression stroke.

Take off the distributor cap. The rotor will be pointing at the number one position on the cap. Follow the firing order to finish. You can figure out which direction the rotor turns by having some one tap the ignition with the cap off and watching which way the rotor turns.1990 chevrolet caprice is the anyone tat can help get me back on the road?
The manifold will have the cylinders marked so you know which cylinder is which. The distributor cap should have number 1 embossed on the cap. Now look at the engine at the cylinder banks. One bank will be slightly more towards the front of the car. The front cylinder on that bank will be number 1. This is true of all V engines because of the way the pistons have to be arranged to fit opposite each other. All you have to do then is follow the firing order clockwise on the distributor cap.
