Okay, so I have a problem with my car; it will crank over but will not start. I've replaced the timing belt so I know it's not broke. I've replaced the coil DCM, the fuel pump, plugs wires, cap and rotor it was running fine up until I changed the timing belt. I don't know if I broke a wire. I've checked all the fuses. any suggestions?

Good morning,

I would start by checking the compression to verify the timing belt marks to be sure the belt alignment is correct.

I attached the timing marks for you to be sure.

Did you verify fuel pressure from the fuel pump?

Fuel Pump
Pressure
No vacuum to regulator .................... 38 - 44 psi (265 - 304 kPa)
With vacuum to regulator .................... 33 - 37 psi (226 - 265 kPa)

Did you verify the spark to the plugs?

Fuel pump, ignition coil injectors, ECM module, cap and rotor are all new. It was running fine until I changed timing belt. I put it back on exactly how it came off. The only reason I decided to change belt was because it was starting to make noise. I was thinking it might have something to do with security system but can't seem to figure it out. I will pull it back apart to double check timing marks.

I would check the compression first. If it is low, that will confirm it.
