The troubleshooting charts for your ignition system are copyrighted and I cannot post them here. You can have access to them by subscribing to alldatadiy.com fo a small fee.

The MOST LIKELY cause of your problem is a failed distributor module. (inside the distributor) The symptoms you described can also be caused by many other things like loose or corroded connectors or even a failed Powertrain Control Module (PCM)

SOURCE: 1996 chevy silverado v8 4.3 won't crank. Replaced

Check the voltage coming from the battery and check it again at the coil.I suspect you are not getting the proper voltage going through. Clean all the terminal ends to bare shiny metal and make sure all the connections are tight. If I remember correct your truck still has the HEI setup with the coil in the top of the distributor cap. If all the voltages are good, 12+ volts you should replace the coil. Hope this helps.

1990 chevy silverado not turning over


Still sounds off. Take the #1 spark plug out, put your finger in the hole and have someone bump the starter around. As soon as you feel pressure, or a whoof sound (air coming out the hole), stop cranking. Look at your timing scale on the crankshaft pulley: You should be very close to the zero scale on the pointer. Put a socket and wrench on the crank pulley if needed to turn the crank on around (clockwise) until the notch or line on the pulley is right with the zero mark on the pointer scale. Now you are at top dead center of the compression stroke on #1. Take off the distributor cap. The rotor should be pointing directly to the #1 spark plug wire tower. Now that you have #1, follow the firing order around in the direction the rotor turns to check if each of your plug wires are in the right place. Firing order should be stamped on the intake manifold. If a 350 engine, firing order is 1-8-4-3-6-5-7-2. You might need to check that, only going by memory from couple days ago when I had to do this. The cylinders on the driver's side are 1-3-5-7, front to back. On the passenger side, cylinders are 2-4-6-8, front to back.

I have a 1986 chevy 1 ton truck it will turn over but it is not firing to start. it want to crank but something is stopping it


i would replace the ignition control module, i pretty sure if you take the distributor cap off the module is mounted to the bottom of the distributor housing, not as hard toreplace as it sounds, when you go buy the new one ask the auto parts attendant about its location, but im pretty sure im right

Start with fuel system. Listen for fuel pump humm at fuel tank No humm check wiring to pump for power. Then check for spark at plugs and wires. Remove wire from coil and hold near engine and see arch when you crank. No arch. Replace ignition Modular inside distributor cap or cap or rotor

Change plugs and wire and engine will not acclerate. This is a built 350 short block chevy with pro charger.


350 Chevy engine in what? 1990 Corvette? Who built it, did you?

Sounds as though you have plug wires wrong.
Firing order is 1-8-4-3-6-5-7-2

Distributor Ignition System:
Distributor rotates Clockwise. (Rotor)
Find Number 1 tower on distributor cap, go Clockwise with Firing Order.

Distributorless Ignition System:
VIEWING the engine from the Front of the car.

Spark plug wire connections along the back, starting from Left side going to Right side;
2-3-7-4

Spark plug wire connection towards the Front of the engine;
6-1-5-8

(To guess I would say you have 5 and 7 wires switched)

Left side cylinder order is 1-3-5-7, going from front to back.
Drivers side is Left side.
Right side cylinder order is 2-4-6-8, going from front to back.

1990 chevy 350 distributor wiring diagram and firing order


The firing order is 1-8-4-3-6-5-7-2.
The distributor rotates in a clockwise direction. The engine must be on the compression stroke on the #1 cylinder. Line up the timing marks. Remove the cap and the rotor should be pointing to approximately the 5 o'clock position.

Good Luck
