I have a 1993 isuzu pickup and because of the design of the carburator and the polution control there are so many vacum lines that without the air filter the vacum, is off just a tip I had lost my air filter cover and was having carburator problems I bought a new weber carburator came with its own air filter was able to plug up alot of the vacum lines runs alot better better gas mileage was only 270 on ebay
if it's not running right check the vacum hose's
hope that helps good luck

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.

Do you think the primary fuel filter under the tank could be blocked or water is in the fuel?

I have a 1993 isuzu pickup act like its not getting fuel runs fine at idle but under pull it starves the longer it runs the worse it runs


Could a lot of different things, remote diagnosis is difficult and you could replace a lot of parts guessing. I think this is a case where it is worth paying a good mechanic to at least make a diagnosis. You may choose to repair it yourself to save money, but I think it would be worth the $50 or so for proper diagnostics. Otherwise you could easily spend that much replacing good parts and not fix the problem.

Has it been tuned up recently (new plugs, wires, fuel filter, air filter)? If that needs to be done anyway, then do that, and see if it helps. Otherwise, pay for a diagnosis. It could be a mass air flow sensor, or throttle position sensor, or EGR valve, or oxygen sensor, or any of several other things.

93 trooper engine not turning over. is getting gas, new fuel pump and fuel filter on it. Is getting fire, but wont turn over.


Use a few squirts of starter fluid directed into the air intake. Remove the air cleaner if you wish in order to get a straight shot into the air intake. If it still will not start, you may want to have your battery checked, along with your charging system. Joe
