Car fuel cleaner

Hi, Could be fuel related. Fuel pump, fuel filter, fuel regulator etc...
Have it checked out by your mechanic. Some parts are computer controlled. You may need code scanner to find problem. Good luck

When you chaged the air filter & sprayed Gumout carb cleaner, you got rid of a little gunk in the
air intake, but when you added the fuel injector cleaner (its the same stuff as carburator cleaner) to the fuel tank, you "cleaned out" ALL the ****/gunk/buildup/dirt in the fuel system which has built up since 1991 and sent it straight to the fuel filter, which is now clogged. The reason that the car tries to start, but fails, is that it'll successfully burn up any fuel that gets past the clogged fuel filter, but the engine consumes that small amount of gasoline quickly, then dies.
Your solution: change the fuel filter.
The fuel filter is located:
Under vehicle, driver side, below seating area, near fuel tank, mounted on frame rail in fuel line

Fill tank and put in a GOOD fuel system cleaner. (STP, Gumout, etc..) Running it out of fuel could've have damaged pump, fuel actually "cools" pump, running out and having to re-prime might have damaged pump. Try the cleaner first (pump replacement is not cheap) and consider changing fuel filter soon also.

Make sure you use a Mass Air Flow Sensor cleaner made by CRC.Do not use( GUMOUT CLEANERS) it not good on your rubber seals.Also wait until your fuel tank is low then add some fuel injector cleaner. You can do this yourself no problem.Also next time when you fuel up try useing high test fuel that will help clean you engine also. Hope this helps

I had the same problem with my 98 Corvette with 69K miles. Mine did exactly as you described soon after I purchased it in November of this year. I went online and read posts of others with the same problem and how to try and fix it. At 1/4 tank add 2 bottles of Chevron Techron cleaner and fill up with good name brand premium fuel. The Techron cleaner will clean the sulfur residue and other contaminants off of the fuel level senors in each of the left and right hand side gas tanks (C-5's have two gas tanks on either side connected by a transfer pump with each side having it's own fuel level sensor). I did this and so far after nearly 3 tankfuls there's been no recurrence of the problem. However, if this doesn't help then the alternative is to replace some if not all of the components mentioned earlier. I got a $1300+ repair quote from my favorite garage prior to applying the above fix. I'm no mechanic and I may have some of the actual part names incorrect. I hope this helps you out and fixes your problem! BTW, you can also use a full can of SeaFoam cleaner in lieu of the Chevron Techron cleaner. I used the two bottles of Chevron Techron the first tankful and used SeaFoam in the second tankful. I plan to use a bottle of SeaFoam every 3-5K miles to help keep this problem at bay and keep my fuel system cleaner!

You didn't say how much fuel is in the tank when this happens. Some of these old GM cars will starve for fuel if the tank is near empty and you are braking or stopping with the car facing downhill. It could be rust or scale in the fuel tank clogging the screen around the fuel pump inlet. Sometimes, putting cleaner in the tank of an older car will only cause more debris to loosen up from the inside of the tank and make the problem worse. If the problem gets worse, I would guess tht a new fuel pump/sloat assembly is in order. You may have to have the tank removed and cleaned or replacedd with a new one to prevent the problem from reocurring.

Most cars and truck nowdays show the tank empty when you start it. Then it slowly advances to the correct level of fuel in the tank. You can try and use some fuel additives like Gumout or Valvoline that clean the injectors and other fuel sytem parts. You can get a buildup of tarnish in these parts and this can cause slow readings. If this was the case it should improve after a few tank fulls of gas with the cleaners added. The guage could also slowly be going bad. The newer style guages are connected to the fuel pump and you will need to replace the whole unit if this goes out on you. Keep in mid that when the fuel pump quits, it quits, usually without much advance notice. If the car starts sputtering and does not have full power, this will hint at the fuel pump going bad. If your car has over 100,000 miles on it, you might want to think about preparing to change the fuel pump, these seem to want to go out shortly after 100,000 miles, but you can get lucky once in a while and it can last longer. Keeping your tank at least half full with clean gas is a big help, the gas keeps the fuel pump cool so it last longer!

this requires droping the gas tank out of the vehicle. once the gas tank is out turn the retaining ring and remove the fuel pump/sending unit from the tank and replace. most aftermarket pumps come with a diffrent plug and require some rewiring

It seems your car's gas tank needs cleaning. Debris, dirt, or water (moister) will settle at the bottom of the tank and as the car bounces along it lifts up the debris from the bottom . The tank will have to be drained and cleaned. The fuel filter replaced, and the screen on the fuel pump cleaned or replaced. The cause of this is that sometimes people run their cars near empty . When you fill up the car. cleaner fuel will make the car run smooth for a while until it gets to the debris all over again.

If you put a fuel cleaner additive in the tank I would change the fuel filter. I believe on this model it is located in the frame just ahead of the fuel tank on the drivers side. Any foreign material cut loose from inside the tank from the cleaner often clogs the filter.
