As you can see, I have a 1999 Chevy Trailblazer. I drove it to work 3 weeks ago today and when I left from my job, I drove about two blocks and it died in the middle of a major road. Since then I have spent many hours trying to decipher what was wrong with it. It was low on oil at the time (I have since added two quarts of oil to refill it). I know it's a fuel issue, whether it be a bad fuel pump or not, I'm not sure. The engine is definitely not receiving fuel to make it run though. I have heard that there is a failsafe with this model of blazer that causes the computer to send a message to the fuel pump to shut off if it sees the engine is running too low on oil. I have also heard that there is a reset switch to correct this issue somewhere in the vehicle. The automotive manual for blazers from this year shows something c alled the "FUEL PUMP OIL PRESSURE SWITCH" within the wiring diagram, and it leads me to believe that this is the switch I'm looking for. I have checked all of the fuses that have to deal with the fuel system. There is one fuse on the engine underhood fuse block that, when taken out and reconnected, sounds like it is trying to make the fuel pump cut on, as a single click happens, followed by several clicks from the fuel injectors attempting to put fuel into the Throttle Body Injector (It has a TBI system, but I forgot to mention that earlier). This makes me believe that the fuel pump is getting a message not to operate rather than being bad all together. Basically I need to know where the reset switch to correct this malfunction is so I can rule this out prior to replacing the entire fuel pump. Also if you think it could be something else, I would like to know. Any information you can offer me would be greatly appreciated.
have the same problem?
