Question about 2002 Chevrolet S-10

3 Answers

My fuel tank seems to be building excessive pressure, I've changed the gas cap twice, it doesn't matter if the tank is empty-full!! Also, the truck is hard to start unless I cycle the key two or three times before engaging starter. Is my fuel pump going bad??

Yeah that is what it seems like thats why you have to turn your key on so many times to prime your fuel pump. Its not holding pressure in the line while truck is not running.

Do you hear a hissing sound when you remove the gas cap?
If so the vent on the gas tank is plugged or pinched so there is no air getting in to replace the fuel volume as it is used. This back pressure is probably the cause of your fuel pump problems also. When you turn the key on you should hear the fuel pump clicking and building up pressure in the line.Sounds like it is time to take it to a good mechanic.

Check your fuel filter. That is the part that needs to be changed on a routine basis. And, a clogged fuel filter will cause the symptoms you described.

I put 4 dollars in gas in my 98 jmc Jimmie it was dead empty now it does not wanting start out can put a little bit in the the boul and it will fire but it doesn't seam like it is picking up the fuel ...


not knowing the amount of fuel you put in is the problem
how much is 4 dollars because it doesn.t seem much
the fix is a full tank and then if there is no fuel being pumped, replace the pump as the small plastic gears will be melted by running without fuel to lubricate them
always a very bad idea to run the tank empty

Burping noise from gas cap, and fuel irregularity once below 1/4 tank


theres two plugs on the fuel pump. one is for pump and one is for gauge if you take pump out of tank and put a volt meter on the two outer prongs in plug then the two inner two of them will read the same when yoou move the level up and down and when you put meter on other two it will change when you move level or the level part of pump isnt working correctly. my old tahoe did that and when it would get to a 1/4 of a tank i knew it was almost out of gas.

I have an 85 Toyota pick up efi and I put a new fuel pump in and I cant put the gas cap on tight or it builds pressure and with it off it leaks gas out the overflow in the engine compartment?


Either the Gas Cap is shot or the tank vent is clogged. First thing i would recommend would be to try swapping the gas cap for one from another car (without the same problem).
The Gas Cap should be a vented style cap, but if it quits it can build up pressure inside the tank. If swapping the cap doesn't stop the pressure, than the vent is clogged, it's on top of the tank

When pumping gas the pump constantly disengages as if the tank were full - it doesn't matter which station or pump. It goes off about 10 times while filling the tank. I've taken it to the dealer...


Back pressure is going into the gas pump handle. If you havent already done so, when filling your car play around with putting the gas pump handle tube in at a different angle. My car often gives me the shits doing this too. I find that if I turn the handle so that it is at right angles or even completely upside down with the tube pointing in a different direction within the fuel intake on my car it works fine. Can be frustrating though particularly on high flow pumps.

When i fuel up 88 blazer, there is pressure building in the gas tank, ( it hisses when i open the cap) and when driving down the road it seems to be very sluggish and sometimes even dies... but this seems...


the pressure in the fuel tanks supposed to be there,your fuel pump,,,pumps 180lbs of pressure to the engine all the time.your engine requires it. so if you do not hear that pressure when you remove the gas cap,you do have a problem. but it does sound like you have a possible fuel injector or maybe 2 fuel injectors clogging.simple to give you solution.add lucas fuel injector cleaner to your fuel tank.a clogged fuel injector will seem like an engine misfire also,just because fuel bulds in the cylinder at times,then the spark plug fires and then BOOM the engine misses while in motion. sound familiar? the lucas costs $5.00 and will treat 25 gallons of fuel. try this,and please let me know if this helps!!

Youg tank shouldn't build up air.It has a vent or vent hose by the filler sout which maybe pluged or abstructed in some way.......Hope this helps.

97 sl1 started stalling when 1/4 tank of gas now stalls at 3/4 tank replaced fuel pump and filter/regulator twice runs great when full


It seems that cap of the tank is not letting in air to replace the volume consumed by the engine. Earlier, when it used to stall when1/4 full, there must been less blockage of air but now the air inlet must be really clogged-up,so much so that after being emptied 1/4 of fuel, the negative pressure built up inside the tank is enough to negate the fuel pumps capacity & without gas it will stall the engine which is being deprived of fuel.
One way to make sure that this IS the problem, fill the tank half, do not put the cap try a drive at least for 5 miles & if the engine does not stall, then one can be sure that he cap of the gas tank has to be replaced............sodeep
