I had a 1997 s10 4*4 with the 2.8 v6.
mine do that I had to pull the gas tank replace fuel filter plus had to take undo the line from the intake and blow air thru it. Make sure all u're filter are replaced and y u have the tank down replace the fuel pump. I hope this helps u
Many things to check. Wonder if this work was done to alleviate problem or problem was from doing the work.
Putting gas fumes in a 21:1 compression cylinder is sure way to ruin engine.
2 possible problems are losing your diesel fuel draw from an air leak in the fuel lines and an inoperative glow plug timer.
When you change a fuel filter you lose the vacuum lock that is in the fuel lines. Some mechanics add fuel to the new filter to remove some of the air and promote fuel draw. The O rings on the injector lines are a special type which resists petroleum products. Using cheap O rings will cause problems.
Glow plug timer-there is a power Relay to the timer and the timer itself is a type of Relay. You should hear clicking noise and lights should dim as timer provides power to the glow plugs.
Other things to check would be the Vacuum pump as Diesels work differently than gas engines and require a pump to supply Vacuum. Covering the intake suggests engine needs a Vacuum draw.
Weak fuel pump. Too weak to pressurize or draw fuel. Can be measured with pressure gauges.
Really bad rings could also cause symptoms.
Would be interested knowing what proved to be wrong.
Okay, you need to make sure the fuel pump is getting power and that you have the lines hooked up correctly. Also, when you replace fuel pumps you need to remove the air cleaner and use starter fluid to get the engine started.
First make sure you have lots of gas in the tank, between a quarter and half. Turn the ignition on and listen for a humming or buzzing noise coming from the tank. The fuel pump should run for a few seconds. If there is no noise you will have to check for a blown fuse. No bad fuses, change the fuel pump.
If the pump runs, remove the fuel line from the tank end of the filter and turn the key on for a secoond or 2. If there is lots of fuel then replace the filter. If fuel just dribbles replace the pump.
If you have to work on the fuel pump, make sure the electrical connections are not corroded and are not loose. Also check the rubber hoses at the connection. Sometimes they will go soft and collapse, plugging the fuel line. Make sure you put the fuel lines back on properly. Hope this helps.
1) Running fuel pump to remove water from tank will likely not empty it all, but it might help. Will still be some liquid in bottom of tank.
2) More than likely, the gas has gummed up and is no good, While your draining of the tank will help, may still need to change the fuel filter and clean the injectors. The ability to keep engine running while pouring into the intake is a good sign, but mayfind that more parts need to be cleaned and replaced prior to solving the problem.
