I need a spark plug wiring diagram for a 1999 Toyota Avalon. I pulled all the wires without marking the order and completely forgot where they go. Oops!

Only the electric wiring diagram has 360 pages. Impossible to post anything of that here. Sorry

1996-1999 Toyota Corolla valve timing:
It is very easy to install the timing belt on 1997 Toyota Corolla. Do the following:
- Mark the numbers 1,2 and 3 on the spark plug wires with permanent marker or nail polish and remain the 4th one unmarked. This is necessary so that you can easily remember the spark plug wires order later on their original position.
- Remove the spark plugs so that the engine can easily be rotated.
- Rotate the crankshaft clockwise to align the v- groove mark on the crankshaft pulley with the 0 mark on the timing belt cover. If these marks are aligned the piston is always on the Top Dead Position (TDC).


- To replace the timing belt remove the crankshaft pulley, upper and lower timing covers.
- Temporarily screw in the crankshaft bolt in its place to rotate the crankshaft with the spanner and align the v- groove of lower crankshaft gear with the index mark on the oil pump cover as shown in the following diagram.
- Inspect the cam shaft mark through the small hole on the cam shaft sprocket. The punch mark should be exactly behind the hole on the cam shaft sprocket as shown in the following diagram.



- Loosen the timing bearing bolt, press the bearing forcefully against the spring with some suitable tool and lock it there temporarily.
- Remove the timing belt.
- Remove the timing bearing.
- Replace the new timing belt and bearing with the original.
- Install in the reverse order of dis-assembly.
NOTE: NEVER PUT EXTRA FORCE ON TIMING BEARING TO ADJUST THE TIMING BELT TENSION. JUST LOOSEN THE TIMING BEARING BOLT AND THE SPRING ATTACHED TO IT WILL PULL THE BEARING IT SELF WITH THE PRESET TENSION TO ADJUST THE TIMING BELT.
Thank you for visiting Fixya.

if you have checked all your fuses try tracing the wiring back to fuse box last time i had this problem it was in the wiring just out of the fuse box

They should have replaced the plugs prior to installation. If this engine is misfiring, there maybe more issues than a simple tune up problem. Make sure all wiring harnesses are properly connected, no fuel leak is present. GoodLuck!!

TRY THIS FRONT 3 CYLINDERS FACING YOU LEFT TO RIGHT 2 4 6 AND BACK CYLINDERS LEFT TO RIGHT 1 3 5 NOW TAKE THIS NUMBER 5 1 3 THIS IS SPARK PLUG WIRES LOCATION FROM LEFT TO RIGHT.PUT PLUGS WIRES TO THE 3 BACK CYLINDERS IN SAME ORDER YOU SEE NUMBER.LET ME KNOW WHAT HAPPENS.
