Engine won't start

It is 1-3-4-2 with No 1 being at the timing belt and crank pulley end.

i would start buy checking you disturber see if you have spark when it dies

Either worn valve guides, valve guide oil seals on that particular cylinder, or worn piston rings. You need to perform a compression test to find out which one of these it is.

Compression check each cylinder with all plugs removed. Take notes on which cylinder has the weakest compression.

If no compression difference and if all operating within range, then change the valve guide oil seals on problematic cylinder.

If the cylinder shows a significant drop in compression, then drop no more than five or six drops of oil down the plug hole of the problematic cylinder, and perform the compression test again. The oil will temporarily seal any worn piston rings, so the pressure should rise when retesting if the rings are worn. If the pressure remains low, then your valves are not sealing properly and require attention.

I'll be interested to see what the other Toyota mavens here think. I'd say the 1990 plug, I'd try a set of NGK BKR5ES-11. They are the cheaper type, not platinum.

It may be
- faulty spark plugs
- faullty plug wires
- faulty distributor
Here is a link for a later model, but with helpful test procedures

I would not spend that kind of money on spark plugs

Just install double platinum

Do not install Bosch with the silly 4 prongs etc
they won't work in some motors

Stay with the OE electrode shape

Spark plugs will make no difference what so ever
as to upgrading to Iridium

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.

HI. The bosh platinum brand will be the better solution.

Bosch Platinum+2 offers great firing technology, which combines the advantages of 2 nickel-yttrium ground electrodes, pure platinum center electrode and surface air gap technology for optimum engine performance, smoother acceleration and better gas mileage. The key here is "better gas mileage"

I run these plugs myself, and they are very nice replacement plugs

It's according to how man cylinders in your engine. 4 with 4 cyl and 6 with 6 cyl

• Available engines
  • 4 Cylinders E 2.4L MFI DOHC
  • 6 Cylinders A 3.3L SFI DOHC (found in 37% of 2006 Toyota Camry)
  • 6 Cylinders F 3.0L SFI DOHC (found in 63% of 2006 Toyota Camry)
