Question about 1995 Isuzu Pickup

1 Answer

My isuzu truck is hard to start. After starting it runs fine for 5-10 miles and bucks/misses for a second and runs fine for another while before doing it again. I replaced the timing belt, computer and the MAF sensor. Prior to replacing these items the truck ran fine and started quickly. Could my fuel pressure regulator be the problem?? I replaced comp because it was dead and the MAF because I thought that was my problem before realizing the comp was no good and I couldn't return it (electrical).

Try changing the fuel filter first. a dirty air filter will put the MAF out of range. How do you know the ECU was bad? They rarely go out. Do an ODBII scan of stored fault history and use that for any repairs to avoid buying parts you don't need

after you did that did you hook it to a car computer to reset the lite? most need this and you can go to a auto zone and rent the computer for free just a deposit and then you get that back. the computer will do it almost for you.

You need four things for an engine to run. 1. fuel 2. spark 3. compression 4. timing (spark at the right time. By your post it seems you have fuel and spark and you probably have compression unless you blew a head gasket. That leaves the timing. Check the timing and/or the timing belt or chain whichever you have.

Disconnect the fuel line at the fuel filter. Turn the car on for the pump to be on. If you are getting gas pumped out, then your pump is good. If not there's most likely your problem. Then try the line at the engine. Disconnect and see if the gas is making it that far. Your should also be able to hear the pump come on if you open the gas cap and listen while someone turns the key to the on position.

Sou. Like you may have some bad ignition wires, worn out spark plugs, or leaking coils. With the engine running spray the ignition wires with soapy water and then drive. If the problem is present replace the wires.

Lost power to engine


Check make sure all plugs are firing. Sounds like what my 93 Rodeo was doing-Idled okay but very rough when in gear. Turns out only 5 out of 6 plugs were firing due to a defective ignition module- 100 bucks later it works fine.

Hope this helps.
