Need wiring digram from spark plugs to distributor cap

We do not have wiring digrams here but you can access them and all the factory service information here for a small fee.

that sounds like maybe a couple of wires got crossed recheck the wire digram and then check the wires, next check the cap and rotor it might be cracked start with these things

Firing order is 1-3-4-2 Please rate if this helps

Installation of wires

1. Whenever a high tension wire is removed for any reason from a spark plug, coil or distributor cap, or a new high tension wire is installed, Silicone Dielectric Compound WA-10, D7AZ-19A331-A (ESE-M1C171-A) or equivalent must be applied to boot before it is reconnected. Using a small clean tool, coat entire interior surface of boot with Silicone Dielectric Compound WA-10, D7AZ-19A331-A (ESE-M1C171-A) or equivalent.

1. Insert each wire on proper terminal of distributor cap. Ensure wires are all the way down over their terminals. The No. 1 terminal is identified on cap. Install wires starting with No. 1 terminal.

1. Remove wire retaining brackets from old high tension wire set and install them on new set in same relative position. Install wires in brackets on valve rocker arm covers.

1. Connect wires to proper spark plugs.

1. Install coil wire.

Installation of distributor
Before installing distributor, visually inspect distributor. Inspect O-ring. It should fit tightly and be free of cuts. The drive gear should be free of nicks, cracks and excessive wear. Rotate distributor drive shaft. It should move freely, without binding.

1. To install distributor correctly, No. 1 piston must be at Top Dead Center (TDC) of compression stroke. Remove No. 1 cylinder spark plug and rotate engine clockwise until No. 1 piston is on the compression stroke.

1. With No. 1 piston on compression stroke, align timing pointer with TDC on the crankshaft damper.

1. Align locating boss on rotor with hole on armature. Fully seat rotor on distributor shaft.

1. Rotate distributor shaft so blade on rotor is pointing toward mark on distributor base, that was previously made in Step 2 of the Removal procedure.

1. While installing distributor, continue rotating rotor slightly so leading edge of the vane is centered in vane switch stator assembly.

1. Rotate distributor in block to align leading edge of vane and vane switch stator assembly. Verify rotor is pointing at No. 1 mark on distributor base. If vane and vane switch stator cannot be aligned by rotating distributor in cylinder block, remove distributor enough to just disengage distributor gear from camshaft gear. Rotate rotor enough to engage distributor gear on another tooth of camshaft gear. Repeat Step 1 if necessary.
   

1. Install distributor hold-down clamp and bolt. Tighten bolt, but leave it loose enough to rotate distributor.

1. Install distributor cap, No. 1 spark plug and ignition wires. Check that ignition wires are securely connected to the cap and spark plugs. Tighten distributor cap hold-down screws to 2.0-2.6 Nm (18-23 lb-in).

1. Reconnect distributor to wiring harness.

1. Set initial timing according to procedures found in Section 13A of the Powertrain Control/Emissions Diagnosis Manual .

1. After timing is set, tighten distributor hold-down bolts to 23-34 Nm (17-25 lb-ft).

1. Recheck initial timing. Adjust if necessary.

You may have got the spark plug wires out of sequence.
Reseat the coil wire going to the center of the distributor cap Check the spark plug wires at the distributor against the firing order as follows:
The spark plug firing order is 1 - 4 - 2 - 5 - 3 - 6 The distributor rotor turns CLOCKWISE The engine cylinders / spark plugs are numbered :
firewall 3 - 6 2 - 5 1 - 4 front

OKAY STANDING IN FRONT OF ENGINE ON LEFT SIDE CYLINDERS FACING YOU IS 1 3 5 ON RIGHT SIDE DRIVER SIDE CYLINDERS FACING YOU IS 2 4 6 LOOKING AT DISTRIBUTOR CAP NUMBER 1 SPARK PLUG ON CAP IN THE 9 OCLOCK POSITION YOUR NUMBER 5 SPARK PLUG ON DISTRIBUTOR CAP IN 6 OCLOCK POSITION .STARTING AT NUMBER 1 SPARK PLUG ON CAP COUNTING CLOCKWISE COUNTING 1 2 3 4 5 6 THATS YOUR SPARK PLUGS WIRES ON CAP TO ENGINE PLUGS. 6 PLUG WIRE ON CAP IS AT 7 OCLOCK POSITION.

Hope this is helpful.

Disconnect the wires and take pictures with cell phone for reference to ensure you don't cross them when reinstalling the new distributor cap. Remove the two torque screws in the distributor cap and remove the distributor cap to access the rotor. Remove the rotor by lifting straight up and inspect the distributor for any condensation and corrosion. Clean the breather screen at the bottom of the distributor before installing the new rotor which just slides back in place. Install the new distributor cap and tighten the new torque screws, make sure you do not over torque the screws since the distributor housing is plastic and prone to stripping. Reattach the spark plug wires and start the engine and idle for 5 min and go for a test drive. Good luck and you may want to also buy spark plug boot lubricant to ensure the spark plug wires are fully installed when placed back on the new distributor cap and recheck connections after test drive. Keep me posted, be glad to know your blazer is running 100% and please rate.

Your car should be a L-28 1,5,3,6,2,4 on the cap looking straight down at the cap:( the rotation on the cap is counter clock ways( release the distributor cap remove the 1 spark plug (1st plug closest to the front of the engine) remove the coil wire from distributor cap and ground on a stud sticking up on a bolt on engine. crank engine with a hand held starter switch. till crankshaft timing mark lines up on 8% after top dead center. remove remote start switch take a long screw driver and place it into the 1 spark plug hole (if the screw driver drops all more then 8 in. you are on exhaust stroke if it drops a couple in you are on compression stroke) it needs to be on compression stroke if it is not then remove screw driver and reconnect remote start switch. turn engine over till it has made 1 hole revaluation back to the mark on flywheel. remove remote start switch. place screw driver back into spark plug hole it should drop a couple inches. remove screw driver replace plug. and wire on spark plug now looking down at the distributor. the rotor should just be hitting the 1 spark plug going counter clock ways that post on the cap is 1 spark plug( place plug wires looking down at top of cap 1,5,3,6,2,4 on the block 1 ,2,3,4,5,6 replace cap and clamp . replace coil wire . remove vacuum advance, vacuum line and plug. loosen distributor. install a timing light and start engine . pointing timing light at crank shaft. you will see the timing mark on the crank shaft twist distributor til marks line up stop engine and tighten distributor recheck timing after tighten to make share it is still right you have about &% you can be advanced and still be ok replace vacuum and you shouls be all good.....

Hi
Here is a diagram.

A diagram may not be needed as its a reasonably easy fix to do on your own.the distributor ca p will only fit on properly one way because at the base of the cap locaters can only fit the distributor if they line up.When doing the spark plug leads do them one at a time and if nessecary write or mark leads as 1,2 etc .The rotor can only fit on one way but put a mark on the distributor to show where the rotor was pointing when you took it off and if it still points there when the new one is fitted.When changing distributor cap and leads they have to go to the correct place.Pays to mark the outside of distributor cap where the locating bits are On the new and old one.Fit the new cap and rotor then take a spark plug lead and fit to new cap 1 at a time.You can tell by lining up the marks on the outside of the distributor cap when you hold them one on top of the other.Good luck
