Use a gage and check proper fuel pressure, 41--47 psi, key on engine off. Cycling the key on and off a few times before you crank it, should prime the system.
Check for fuel injector pulse, use a noid lite, engine cranking. The voltage for fuel injector probably goes hot with the key on. The computer grounds the fuel injector circuit. The diagram is for 2.2L engine. The pink wire for fuel injectors is voltage, the bottom wire is ground. We've talked about the fuel system, could be other issues?
sound like the o rings are worn out on fuel rail when you pull the rail out slightly you are pinching the bad O ring making a seal car is starting. I would replace all O rings check fuel injector seals too, any and all vacuum lines and the seal on the fuel regulator especially if it is connected to the fuel rail. also check and see if you are moving a wire connections when moving the fuel rail possible loose connection.
Hello
This problem is often caused by a defective fuel pressure check valve in the outlet of the electric fuel pump. When the car sits the fuel leaks back into the fuel tank and the lines must be "purged" before the engine gets a steady fuel flow at the correct pressure and runs ok, this is why cycling the key off and on gets the engine running. The fuel pump is only turned on for one second unless the engine is cranking over. To confirm this cycle the key three or four times from on to off and back on (without cranking engine), if the engine starts and runs ok you likely need to replace the in tank fuel pump.
It is probably one of the fuel injector O-rings. You'll have to remove the injectors to replace the rings. There is one where the injector attatches to the fuel rail and one on the other end of the injector where it goes into the plenium.
Once the hold down for the injectors is off, carefully pry out the injectors with a blade screwdriver(BE GENTLE! I have broke them before pulling them out) The easiest way to get the injectors back in is use a small amount of regular dish soap on the o-rings, it works great to make them slide in easily without cutting the o-rings.
Disconnect the negative battery cable.
Before servicing any electrical component, the ignition key must be in the
OFF or LOCK position and all electrical loads must be OFF, unless instructed
otherwise in these procedures. If a tool or equipment could easily come in
contact with a live exposed electrical terminal, also disconnect the negative
battery cable. Failure to follow these precautions may cause personal injury
and/or damage to the vehicle or its components.
Remove the air cleaner outlet resonator mounting screw.
Disconnect the air cleaner outlet resonator clamp at the throttle body.
Remove the air cleaner outlet duct from air cleaner outlet resonator and air
cleaner assembly.
Disconnect the crankcase vent hose clamp and the crankcase vent hose from
the top of the engine.
Remove the air cleaner outlet resonator.
Remove the fuel rail bracket.
Remove the fuel injector electrical connectors by pushing in the wire
connector clip and pulling the electrical connector away from the fuel injector.
Remove the fuel feed inlet pipe quick connect.
Remove the fuel return pipe from the fuel pressure regulator.
Remove the fuel rail attaching bolts.
Remove the fuel rail assembly from the cylinder head.
Remove the fuel injector retaining clip.
Remove the fuel injector.
Important Visually inspect the fuel injector to see if the upper O-ring was
also removed, if not, remove the O-ring from the fuel rail assembly
