93 isuzu rodeo with 3.2 engine cuts off when you give it gas


Vehicles need fuel, spark, and air to run. You started with the basics like spark and fuel, great. Slow down on the parts installations and take yourself back to basics.

1. Check your fuel lines for leaks.
2. Inspect the vacuum lines for cracks ( you stated it got cold outside. This may contribute to old hard lines cracking).
3. Remove the air filter box and filter and make sure airflow is free of any blockage. Test car without air filter installed and see if it stays running while giving gas. If it does replace air filter
4. Check the throttle body Mass Air Flow Sensor. This detects how much air is coming into the system. It reports to the main computer. If the MAF tells the computer there is significantly not enough air the the system will shut down. My guess would be a big vacuum leak or you have a bad MAF.

I have a 2000 isuzu rodeo and Its a air and fuel mixture. I'm getting to much fuel and not enough air. Then when i ease into the gas it runs fine then when you push the gas pedal down further to the floor...


have a pressure test done on the fuel manifold to check for fuel regulator/ pump problems. Have the injectors check for leakage. run fault codes to check air sensors faults

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.

99 Rodeo 3.2 V6 fuel injected .


sounds like u may need a new fuel pump, the problem is the system doesn't hold fuel pressure after shut down, the check valve that does this is part of the fuel pump in the gas tank.
