You can not diagnose or resolve anything by changing parts

You need wiring diagrams of the circuit your having issues with,
to follow a logical path to success

Only knowing the system & proper testing will find the cause of
the pump not running,etc

SOURCE: isuzu rodeo sport 4wd, stuck in 4wd

Don't know if this will help with your exact problem, but I can share with you how I have "fixed" this.

If the 4WD indicator is flashing, then it means the 4WD select switch is working but the 4wd "clutch" hasn't released. Backing the vehicle up slowly, or sometimes just switching into reverse with the 4WD switch in the 2WD position is usually enough to release the 4WD and the 4WD indicator should go off. It after all this, the indicator still does not go off, it could be some issue with the electric 4WD clutch not releasing.
You should be able to tell if the 4WD drive is still engaged by driving slowly in a circle. On drive pavement, the front wheels will "hop" around. Don't do this too fast or too often on drive pavement, since the part time 4WD was not meant for this. The front wheels have to be able to slip in relation to each other, when in 4WD.

Hope this helps and wish you well in your troubleshooting.

Locate the Fuel Filter and Take it loose. Try to Start the Truck, If the Pump is Good, Fuel will come out of the Fuel line going to the Filter. Please Rate My Response! Thanks!

SOURCE: no power to fuel pump 1996 isuzu rodeo

well i got a salvaged ecm from a junkyard and put it in, still did'nt start. took alternator off to have it checked , it is fine. put it back in and now it starts and runs fine. check the alternator and the connections, i heard the alternator controls power after the initial ecm prime when it is turned on. i have no idea how true it is, but worth a shot. if you can find a cheap ecm for a junkyard (mine was 75 bucks) i would try that afterwords.

SOURCE: replacing the power steering pump on a 1998 isuzu rodeo

Remove low pressure and high pressure hoses (this one could be hard to break loose). You might want to have an oil pan handy, to capture the oil. Disconnect electrical sensor. Remove the bolt that holds belt tension adjustment plate. And finally remove the bolt that holds the pump in place. It is bolted from the back and located at the right lower corner of the pump if you are facing the front of the car. Remove the pump assy. I could not remove belt pulley at home, no matter how hard I tried. Ended up taking it to an automotive shop and they removed it in no time, using one of those "pneumatic impact guns". Assemble new pump. Fill the reservoir with PS oil. Make sure both of the front wheels are off the ground, start the engine and slowly spin the steering wheel back and forth for about 5 minutes or untill screeching sound stops and the liquid in the reservoir stops foaming. That will bleed any air that is in the system. Don't go all the way to the end of stroke. Good luck.

You may want to try to see if the car will start while you spray starting fluid down the throttle body. If it doesn't, the problem may not be the fuel pump at all. There is an idle air control valve bolted to the front of the throttle body that can keep the car from starting as well.

If the car starts with the starting fluid, you might want to change your fuel filter. It's mounted under the car near the passenger rear door.

Underhood fuse block swap out relay #7 thats the ECM relay.
Ground Circuits Using a DVOM, touch negative voltmeter lead to a good ground. Touch positive voltmeter lead to each ground terminal. With vehicle running, voltmeter should indicate less than one volt. If reading is greater than one volt, check for open, corrosion and loose connection on ground lead. See ECM GROUND LOCATION table for ECM ground location.

Rodeo will tun over but will not start


I had the same problem and read on several foruns that the FUEL PUMP is behind the rear passenger side tire, Usually its the wiring not the pump, and in my situation it was the MAP sensor.
Acted like it was not getting gas but was, changed the sensor and it was running again.
Good luck.
