3.2TL TYPE S V6-3.2L SOHC (2002)
8. Attach the fuel pressure gauge.
9. Disconnect the vacuum hose (A) of the fuel pressure regulator, and pinch it closed with a clamp (B).
10. Reconnect the negative battery cables, and start the engine and let it idle.
-
If the engine starts, go to step 12.
-
If the engine does not start, go to step 11.
11. Check to see if the fuel pump is running. listen to the injector rails underneath the intake manifold cover while an assistant turns the ignition switch
ON (II). You should hear the fuel flow through the injector rails for about 2 seconds when the ignition turned ON (II).
-
If the pump runs, go to step 12.
-
If the pump does not run, test the fuel pump.
12. Read the pressure gauge (with the fuel pressure regulator vacuum hose disconnected and clamped). The pressure should be 280 - 330 kPa (2.9 -
3.4 kgf/sq.cm, 41 - 48 psi) for '99-00 models or 330 - 380 kPa (3.4 - 3.9 kgf/sq.cm, 48 - 55 psi) for '01-03 models.
-
If the pressure is OK and engine is running, go to step 13. If not running, repair the cause, then continue this test.
-
If the pressure is out of spec, go to step 14.
13. With the engine running, reconnect the vacuum hose and read the gauge again. The pressure should be 220 - 270 kPa (2.25 - 2.75 kgf/sq.cm, 32 -
40 psi) for '99-00 models or 270 - 320 kPa (2.75 - 3.25 kgf/sq.cm, 40 - 46 psi) for '01-03 models.
-
If the fuel pressure is OK, the test is complete. Go to step 15.
-
If the pressure is out of spec, go to step 14.
14. Disconnect the vacuum hose from the pressure regulator again while you watch the pressure gauge. The pressure should rise when you disconnect
the hose.
-
If the pressure did not rise, check the vacuum hose for leakage, clogging or loose connections. If it's OK, then replace the fuel pressure
regulator for '99 model or for '00-03 models and recheck the fuel pressure.
-
If the pressure rose, and all your readings were within spec, go to step 15.
-
If the pressure rose, but your readings were out of spec, check for these problems:
-
If the pressure is too low, check for a clogged fuel filter and for leaks in the fuel lines.
-
If the pressure is too high, check for a pinched or clogged fuel return hose or line.
15. Reconnect the vacuum hose, remove the pressure gauge, and reinstall the fuel pulsation damper and a new washer. Tighten the fuel pulsation
damper to 22 N.m (2.2 kgf.m, 16 lbf.ft).
NOTE: Disassemble and clean the fuel pressure gauge attachment thoroughly after use.
