Scotty, You are the best. I have a 2000 celica and I recently changed the fuel injectors. It would not pass inspection and that is what they narrowed it down to. After I did that it ran like a charm and the check engine light went out and it passed inspection. Two days later I went to start the 2000 celica and now it hesitates and acts like no fuel pressure is holding fuel to the fuel rail. I don't see a fuel pressure valve on the car and I looked at the fuel injector rail and I don't see a nut to loosen to see if pressure is holding on the rail. After a few cranks it finally starts and then runs great. It is an older model car and I think I may have to change the fuel pump and filter. I don't look forward to taking out the back seat. Do you have any idea what might be the issue. Also, how would I check each spark plug since they are single coil on plugs. Would there be a crankshaft position sensor in a 2000 model celica?
Thank You.

Couple of other questions. I found what I think is the fuel pressure regulator. It is built into the middle of the fuel rail ? It is the only aluminum mostly flat thing that I could find by the fuel intake on the motor. . Also, do you have a diagram of the crankshaft position sensor and a diagram for the fuel pressure regulator and where it would be? I am good with pics and photos in order to get to where I need to go. Luckily there is a video on youtube of the same model celica where someone is changing out the fuel pump and filter.

those are known for fuel pump and fuel pressure regulator faiures, I would start there. And it does have a crank sensor, a cow to get to as follows: REMOVAL

  1. REMOVE INTAKE MANIFOLD
  2. REMOVE ENGINE UNDER COVER RH
  3. REMOVE CRANKSHAFT POSITION SENSOR

Also, the car has a new gas cap, and when I stopped at autozone it coded a P00440
