How to remove spark plug wires from the distributor on a 1992 camry 3.0l 6 cyl they have some sort of cover for each wire

if you mean the plug wires do the following. remove number one spark plug,turn engine over till you feel compression coming out of cylinder, find tdc mark on timing cover, turn motor over till mark on crankshaft pully lines up with timing cover mark, remove distributor cap, rotor now points to number one plug wire, check rotor rotation, firing order 4 cylinder motor 1324 6 cyl 153624.

I do not think the wiring harness needs replacing, although it may be a bad connection somewhere in a car this age. See here

If it is the old 3VZ V6 you have, it is broadly similar to a 4-cyl times 2. If it is a 1MZ v6 it may have individual coil packs on each plug, although probably not as you describe it.

Page 4 will show you the number of places a failure can prevent a spark. Try following the troubleshooting charts in this reference to track down the fault. It could for instance be a faulty igniter unit.

First, you didn't mention which engine your 1994 Toyota Camry is equipped with. (This is really MUST-KNOW information if you want help with fixing your car.) There is a 3.0L V-6 engine and a 2.2L 4-Cylinder engine. Two TOTALLY different animals! I'll just take the extra time to answer for BOTH of them....

If your Camry is equipped with a 3.0L V-6 engine, You cannot find the spark plug wires because there are none, That engine is equipped with Coil On Plug (COP) ignition. The coils on the left bank (the side of the engine near the radiator) are located under the plastic cover on top of the engine. The coils for the right bank (the side of the engine near the firewall) are located under the upper intake plenum. The plenum MUST be removed to access them. (this is also required to replace the spark plugs.)

If you have the 2.2L 4-cylinder engine, the wires run down the center of the valve cover and the boots go down through the valve cover to the plugs. The other end of the wires attach to the distributor cap at the rear (drivers side) of the engine.

Hope helps.

Three seals to check. easiest is the valve cover seal. Number and remove the 4 wires going into your spark plugs. remove 4 nuts holding the cover and replace seal.
Next easiest is the distributor O-ring. Remove air filter assembly remove the distributor cap, then the distributor. With the valve cover still off, loosen the 2 bolts that clamp the distributor down. Remove the 2 terminal leads going into the distributor (4 wire terminal/2 wire terminal) Mark the case of the distributor and the case of the head with one line so you can line it back up on reinstallation. remove the 3 bolts holding the distributor down. Replace O-ring. replace distributor, align, tighten the 2 bolts, then tighten the 3 bolts. replace terminal wiring and cap. replace air filter assembly. Replace valve cover with new gasket. Place spark plug wires back into their proper places. The last one is the oil pan gasket. Drain all oil and remove all blots holding the pan. drop the pan and replace the gasket. Put it all back into place. Do not over tighten the pan bolts as this will cause the gasket to deform, making it leak again.

Take out a spark plug, lay the plug (with the spark plug wire attached)on the engine and turn the motor over, if it sparks, your getting fire, Try each plug, works best a night so you can see the spark.

I believe your firing order is 1-3-4-2. You may see a number 1 on the distributor cap on this vehicle. That is the #1 plug wire. The wire hole next to that would go to spark plug 3 etc. Easiest way is to change wires one at a time. Hope this helped.

have your timing belt checked. and your wires replaced. well the ones going from the distributor to the spark plugs.

Good luck and hope this helps.

Review the Jeep ZJ Repair Manual in the Firing Order (page 10 and 11) for 4.0L 6-cyl and 5.2L 8-cyl.

I really hope hepled with this (remember rated this help) Good luck.
