Question about 1998 Chevrolet S-10 Pickup

1 Answer

My 1998 S-10 is not getting gas to the throttle body. I can pour gas down the throttle body and it will turn start and I am able to drive for miles. Once I turn it off, I have to repeat the process of pour gas in the throttle body. What should I be looking for as the culprit. Are there sensors that give a burst to the throttle body, once I turn the key?

When you first turn the key on you should hear the fuel pump run for about 10 seconds . this primes the fuel system .If you do not hear the pump run then you need to check the circuits for the pump
the fuel pump has a fuse and a relay that is use to power up the pump . you should check the fuse and if they are ok then switch the fuel pump relay with a like one in the fuse box (horn relay is the same as the fuel pump relay ) I think the fuse and the relay are both in the under hood fuse box on your truck . If these all check out ok then you need to check for power and ground at the fuel pump connector . if this checks out all good then replace the fuel pump . some times if you think the pump is not working you can bang on the gas tank with a rubber mallet this may move the pump winding off of the dead spot and the truck will start ... but this is not a fix .. just a way to get it started to move it or take it to a shop

I'd like to get step to step instructions on how to clean the throttle body in my 2010 Jeep Patriot


  1. Purchase "02 Sensor Safe" throttle body cleaner spray;
  2. Drive the vehicle a few miles, bringing it to full operating temperature, then park it in your driveway with the engine still running;
  3. Gain access to the throttle body, and hold your thumb on the butterfly linkage so that you can open the throttle butterfly when the engine begins to load;
  4. Begin by spraying throttle body cleaner spray on all linkages around the throttle body. If the engine begins to bog because it is aspirating throttle body cleaner, quickly open the throttle butterfly to keep the engine running.
  5. Once you have cleaned all around the throttle body, spray cleaner DIRECTLY INTO THE THROTTLE BODY, opening the throttle sufficiently to keep the engine running. It will run rough during this process but try not to let the engine stall.
  6. If the engine stalls, restart it, and continue cleaning the throttle throat until you see clean metal.
  7. Pour some fuel system cleaner into the gas tank and drive the car a little more before parking it. Try to find an excuse to accelerate hard, WIDE OPEN THROTTLE momentarily if safely possible (as when accelerating to merge into traffic on a highway).
  8. Drive back home.
  9. Done.

The only matter there should be in the throttle body is air. The throttle body in no way has anything other than "nothing" in it. The liquid you see could be the gasoline you threw into the throttle body.

Getting back to your problem. Do NOT have someone looking down the throttle body while you are trying to start the engine. That person may receive a haircut he will never forget! Get the battery charged. Try to start the engine because even though you think you put too much gas in the throttle body, it may start.

The tricky part. If the engine starts and runs for a few seconds, then you are having a problem with fuel delivery and that is the fuel pump most of the time but not always.. If it does not start at all, try one more time to pour gasoline into the throttle body, hold your foot about 1/2 way down on the pedal and then try again to start it. If it still doesn't start, it's time to check for spark.

My 1985 grand Marquis won't start I can pour gas


Take the gas filter off. Should be located near the front of the carbeurator, take off the air cleaner and look for it, it takes 2 wrenches to take it off, a little gas may spill out but not much and replace it, however there is a strong possibility that he gas pump is out if the filter is fine. Hope this helps

My 2001 Sequoia won't start. I poured gas in the throttle Body and it still doesn't start. How do I test the ignition coil? It does turn over! What else could it be?


If you tried pouring gas down throttle body then it would be a spark problem need a timing light or spark tester to see if the spark plugs are getting spark

Sounds like the fuel system lost its prime.

Remove air cleaner, pour about 1/4 cup gasoline into the throttle body/carburetor, put air cleaner back on, start car. Repeat until it runs. You may get a small backfire in the throttle body, so don't be looking at it while someone else starts it. Good idea just to stand back from engine when engine is cranked.
