Distributor cap cables diagram tahoe 95

I guess you could have the ignition analyzed on an oscilloscope. Maybe a tech could see something then.
I always heard the only gap was the spark plug gap-the rotor has no gap-are you sure you got the correct rotor? And does it touch the top distributor cap coil wire tower?

Let us know. It is a mystery worthy of a solution.

Your vehicle has a distributer cap and rotor. Below is the firing order for you. I hope this helps and good luck.

Replace the distributor cap and rotor. If you have fire from the coil but not from the distributor cap, you have a bad contact point between the cap and rotor. Replace both and you should be good to go,, if the information that you have supplied is correct.

if you remove the spark plugs and move the distributor cap so you can see the direction of rotation have someone crank the motor over is short bursts noting direction of rotation of the rotor and put your finger over the #1plug hole.when #1 comes up to top dead center you will feel pressure against it and hear a compression sound.then you can look into the cylinder and turn over the motor by hand and watch the piston rise in the cylinder until its at the top and doesn`t start to move down.this will be close enough.note were the rotor is pointing and this will be were #1 is on the distributor cap.then install the other wires in the direction of the rotor turning in the proper firing order.the order should be 1-3-4-2.

That is indeed odd. I would suspect problems with the hi tension cables if this was not part of the ones you changed since the flow of current ends at the distributor. Check also other cables such as the ground. It is puzzling that all plugs would not have any spark. I would also recommend a scanner used to check for error codes given out by the car's ECU.

I would start with the rotor and cap. I just worked on one and it was the distributor was bad.

If you need to remove it and rplace it heres how.

Distributor Removal and Installation REMOVAL

1. Remove bolt holding air inlet resonator to intake manifold.
2. Loosen clamps holding air cleaner cover to air cleaner housing.
3. Remove PCV make-up air hose from air inlet tube.
4. Loosen hose clamp at throttle body.
5. Remove air inlet tube, resonator and air cleaner cover.
6. Remove EGR tube.
7. Remove spark plug cables from distributor cap.
8. Loosen distributor cap hold-down screws and remove cap.
9. Mark rotor position for installation reference, then remove rotor.
10. Remove two harness connectors from distributor.
11. Remove two sets of distributor hold-down nuts and washers from studs.
12. Remove bolt and spark plug cable mounting bracket from top of distributor housing.
13. Remove bolt and transaxle dipstick tube.
14. Carefully remove distributor from engine.

INSTALLATION

1. Install rotor on shaft.
2. Position distributor in engine and ensure O-ring is properly seated on distributor. Replace O-ring if it is cracked or nicked.
3. Carefully engage distributor drive with slotted end of camshaft. When the distributor is installed properly, the rotor will be in line with previously marked line on air intake plenum.
4. If engine was cranked while distributor was removed, establish proper relationship between distributor shaft and No. 1 piston position as follows:

1. Rotate crankshaft until number one piston is at top of compression stroke.
2. Rotate rotor to No. 1 rotor terminal.
3. Lower distributor into opening, engaging distributor drive with drive on camshaft. With distributor fully seated on engine, rotor should be under No. 1 terminal.

1. Install distributor hold-down washers and nuts. Torque to 9 ft-lbs .
2. Install spark plug cable bracket.
3. Install two harness connectors to distributor.
4. Install distributor cap.
5. Install transaxle dipstick tube.
6. Install EGR tube to intake manifold. Torque bolts to 8 ft-lbs .

Spark plugs, spark plug wires, distributor cap, and distributor rotor. If you replace all of these you would be doing what is called a major tune-up.

A regular tune-up would be just replacing the spark plugs.

You can check the integrity of the plug wires and distributor cap by spraying them with water while the engine is running. If the engine runs ruff, stall, or you see spark arcing from either the wires or the distributor cap than they will need to be replaced.

The distributor rotor always gets replaced when you replace the distributor cap.

You can also spray the coil with soapy water to see if it is leaking as well.

1-8-4-3-6-5-7-2 The #1 spark plug is the front spark plug on the drivers side and the cylinder location in order from front to back on the drivers side is 1-3-5-7 and on the passenger side it is 2-4-6-8. The ignition rotor rotation is clockwise.

If your Distributor cap is not numbered then replace the new wires, or transfer the old ones to the new distributor cap one wire at a time. Identify the #1 spark plug wire and start from there.

Not sure about your engine size so please pick your model:

2.5L Engine

1. Before servicing the vehicle, refer to the Precautions section.
   
2. Remove or disconnect the following:
   
   • Bolt holding air inlet resonator to intake manifold.
     
   • Clamps holding air cleaner cover to air cleaner housing.
     
   • PCV make-up air hose from air inlet tube.
     
   • Hose clamp at throttle body.
     
   • Air inlet tube, resonator and air cleaner cover.
     
   • EGR tube.
     
   • Spark plug cables from distributor cap.
     
3. Loosen distributor cap hold down screws and remove cap
   NOTE The rotor is friction-fitted to the distributor shaft and can be pulled straight off.
   
   
4. Transfer cables from old cap to new cap. The cap and cables are numbered with their corresponding cylinder numbers.
