Diagram for 3.0 six cylinder timing belt? - 2000 Toyota Camry

Not knowing what the actual problem is I can only suggest the firing orders.
Is yours the four cylinder engine or the six cylinder?
The Four cylinder engine will probably use the sequence 1, 3, 4, 2, as this is usually the most common one in use. Cylinder One is the cylinder nearest the belts and pulleys and you count away from you towards the transmission and gearbox.
The six cylinder uses the firing order 1, 2, 3, 4, 5, 6. Cylinder One is also at the belt and pulley end of the engine but the numbering is different on a 'V' engine. The numbers go 'left, right, left, right, left, right' odd one side evens the other.
Stand next to the engine with the gearbox furthest away from you and the end with the belts and pulley wheels nearest to you. Number One is the cylinder nearest to you on the Left. Number Two is the one nearest to you on the Right. The Left side is numbers 1, 3, and 5 and the right side is 2, 4, and 6,

Firing Order1-2-3-4-5-6.
NOTE: This engine is a six-cylinder engine. The cylinder numbers are assigned as 1-3-5 for the right bank and 2-4-6 for the left bank from the front of the engine (timing belt side). This engine is fired in the order of 1-2-3-4-5-6 cylinders.

it should say on the coil what cylinders the wires go to. How many cylinders 4 or 6? If it's a 4 it runs left to right 1-2-3-4 if it is a six look at the valve covers they are not even.the one that is closer to the belt is # 1 cylinder and it runs 1-2-3 on one side and 4-5-6 on the other i hope this helps you
