[YES]
Go to Step 4.
[NO]
Go to Step 12.
NOTE: The fuel pressure will drop when the fuel pump stops running, then it should stabilize and remain constant.
4. a. When the vehicle is at normal operating temperature, turn the ignition "ON" to build fuel pressure and observe the measurement on the gauge.
b. Start the Engine and observe the fuel pressure gauge.
c. Did the reading drop by the amount specified after the Engine was started?
[VALUES] 21 - 105 kPa (3 - 15 psi).
[YES]
Go to Step 5.
[NO]
Go to Step 9.
5. Is fuel pressure dropping off during acceleration, cruise, or hard cornering?
[YES]
Go to Step 6.
