Just replaced timing and doesnt start

Engine timing is done electronically. It is based on Cylinder 1 being a few degrees before TDC (Top Dead Centre of firing stroke).

Valve Timing is set using marks when you change the timing belt or chain. That is set with Piston 1 at TDC on FIRING stroke.

Here is the firing order. It is nice and easy, 1, 2, 3, 4, left to right.

recheck the firing order . sounds like you have crossed two plugs

There's a chance the cam and crank gears are not in line with each other. You could try placing the rotor 180 degrees from TDC and see how it does.

5sfe is non interference...

Sounds like timing is out .Re set belt.Is it a 5sfe motor?

The TDC mark is usually the second one in the direction of rotation. To make sure you have the right mark, if you still have the tappet cover off, number 1 cylinder valves should rock at TDC when you move the crank backwards and forwards.

check the camshaft and the crankshaft if syncronize or the timing mark is in the right position.
check TDC if the number one piston is on top and the distributor cap is pointing the number one sparkplug cable. if not, TDC is your problem. If your don't know the setting, buy the manual book to the auto parts store, it cost you about less than $25.

ok there is no way to physicaly time the engine with a light. you need to bring #1 cylinder to TDC then install dist. mark contact for ign wire #1 on cap outer as accurately as possible. then mark dist. base with same mark. allign rotor with mark and tighten clamp. assemble and fire make sure fireing order is right,cap is stamped on top. the exact way to set is with a scanner, cam(dist.) sensor and crank sensor need to bolth read #1 TDC at 0 degree advance and tighten clamp, computer takes over from there. be as accurate as possible, if done right it will run, if engine light flashes, your too far off try to bump a tick either way and have a tech set for you with a scanner. best of luck!

this is for the crank pulley timing marks .....

I have a similar problem. I just replaced the water pump and now the POS wont start. Like it is not getting fuel>
