hey guys, i think im having a fuel issue, or a lack thereof. my car is bucking and wont drive at all when cold, will only drive when completely warmed up and you can feel that it is very restricted. try to hit the gas on the highway and she stumbles hard. i want to test the fuel pressure but there is no port on the rail or the fuel line in the engine bay. how are you supposed to check the fuel pressure on this car? it is a 2002 cvt if it matters. thanks everyone.

already replaced the o2's, the cats, did throttle body and egr system cleaning as well as tested coils and replaced the plugs and no nothing died in my intake and the air filter is new as well as the tranny fluid and oil. and no check engine lights or broken hoses and i replaced all the ground straps, i figure fuel is the only thing it could be, the car has 139,000 miles on it.

From the Fuel_Supply_System PDF file, page 37 of 108:

Special Tools Required
Fuel pressure gauge 07406-004000B

2001-2003 CVT MODELS
1. Relieve the fuel pressure (see FUEL PRESSURE RELIEVING ).
2. Remove the sealing nut from the fuel rail. Attach the fuel pressure adapter nut,
12 mm (A) and the fuel pressure gauge (B). Remove the vacuum hose (C) from
the fuel pulsation damper (D), and pinch off the hose with a clamp (E).
3. Start the engine, and let it idle.
If the engine starts, go to step 5 .
If the engine does not start, go to step 4.
4. See if the fuel pump is running: listen to the fuel fill port with the fuel fill cap
removed. The fuel pump should run for 2 seconds when the ignition switch is
first turned ON (II).
If the pump runs, go to step 5.
If the fuel pump does not run, perform the fuel pump circuit
troubleshooting (see PGM-FI MAIN RELAY CIRCUIT
5. Read the pressure gauge. The pressure should be 270-320 kPa (2.8-3.3
kgf/cm2 , 40-47 psi).
If the pressure is OK, the test is complete.
If the pressure is out of specification, replace the fuel pressure regulator
and the fuel filter (see FUEL PRESSURE REGULATOR
REPLACEMENT ), and recheck the fuel pressure.
6. Reconnect the vacuum hose, remove the pressure gauge, and reinstall the
sealing nut with a new washer. Tighten the sealing nut to 22 N.m (2.2 kgf.m,
16 lbf.ft).

There is a picture of the fuel pressure gauge and where it connects in the manual.
