Test Description
WARNING: This page is about a different car, the 2002 Isuzu Trooper, 2002 Isuzu Rodeo Sport, 2002 Isuzu Rodeo, 2002 Isuzu Axiom, and 2002 Honda Passport. However, it is still accessible from the selected car via links, so may be relevant.
Numbers below refer to step numbers in Testing Procedure.
- 5
An obvious cause of low fuel pressure would be an empty fuel tank. - 6
The engine will easily start and run if a few injectors are disabled. It is not necessary to test all injectors at this time since this step is only a test to verify that all fuel injectors have not been disabled by fuel contamination. - 7
A blinking test light verifies that PCM is monitoring the 58X crankshaft reference signal, and is capable of activating fuel injectors. If there is an open or shorted driver circuit, DTCs P0201-P0206 and a misfire DTC P0300-P0306 should be set. - 19
By using a spark tester, each ignition coil's ability to produce 25,000 volts is verified. - 25
If there is an open or shorted driver circuit, DTCs P0201-P0206 and a misfire DTC P0301-P0306 should be set. All 6 fuel injector driver circuits can be checked at one time without removing the intake manifold if a Fuel Injector test light (J39021-95) is available. For alternative procedure for checking fuel injector driver circuits perform following:- With the ignition off, disconnect fuel injector tester Gray 7-pin in-line harness connector. In-line harness connector is bolted to front of right valve cover, below where air duct attaches to MAF sensor.
- Connect test light (J39021-95) to fuel injector tester in-line harness connector. If any of the LEDs are illuminate constantly or fail to blink when the engine is cranked, repair short or open circuit, or replace PCM if indicated.
