Are you sure your idle ports ( size of pinhole) in carb aren't plugged with something? What happens if it starts to die, and you give it a quick squirt of WD-40 , down throat of carb?

Best do a fuel pressure test. Should have chg. fuel filter from the get go. The only other filter is on the end of the fuel pump in tank. Bad gas and dirty gas will plug up fuel filter, hense burn pump up.

After you dump the fuel in the throttle body it will continue to run on its own or die as soon as it burns up all the fuel you dump in? Do you have access to (Noid lights)? Are both plugs attached to the distributor?

SOURCE: 93 gmc sierra 5.7 liter engine, injection carb,

you say you replaced the fuse, but does the fuse have power? the gray wire at pump should have power when cranking, or for 2 seconds when turning key on. At fuel pump relay, put power onto gray wire, the pump should run if the wiring is good. if it doenst run then ck for power at fuse while power is on gray wire.

This happens when the fuel pump is getting bad. I will recommend you do a replacement.

The fuel pump is located in the fuel tank which can be reached by removal of the back seat.

Be careful and ensure the replacement has the same rating with the old one.

Good luck and remember to rate this solution.

1982 JEEP HESITATES WHILE DRIVING AND DIES


2 things. come to mind.
i check the distributor advance works to spec with my timing light (strobe)
if that is ok, its a carb issue.

carbs fail for many reasons, (mostly gummed up inside)
we clean them. that fixes them. (with a kit)
I only have this for symptoms, and is not good.
MAJOR HESITATION AND STALLING OCCURS
does the engine have full power up any hill wide open throttle
is the Hesitation only a short time then catches up.
The carb (not stated P/N or brand) has jets, the if gummed up
will cause lean running.
so will any power valve jet.
ever tune it up. new spark pats, rotor all the way to spark plugs.
bad spark , loves to fail under load, that is its , magic.
carb>
  1. low float bowl levels.
  2. low fuel pressure causing above,
  3. bad float valve , sticks closed and starts bowl of fuel, causing #1
  4. Gummed up jets.
  5. Gummed up emulsion tubes in carb body.
  6. Choke stuck on, causing flooding,
  7. Choke dead causing hard starts . (stuck open)
  8. power valve clogged.
  9. Highspeed accelerator pump bad, causing only sight hesitation.

my guess? based on 1 word "stall" its #1 to 3 or 6.
black spark plug tips would be #6

or if black sparks, the float valve is stuck open flooding engine and stalling.

we can go for days on carbs. but will not.

My 84 f350 is having fuel and air problem. It ran fair but it would backfire when i let off the accelator,so I had the carb rebuilt that made the backfiring worse. So now I have replaced the carb mounting...


It seems that you have a vaccuum leak around the intake or carb, Check all hoses for good connections. You can spray carb. and choke cleaner around the intake and carb whole it is running and if the engine rise and lowers. you have a leak

86 toyota cachked fuses mry stalled while driving


try cleaning out the carb, replacing fluids, and then put a fuel filter on it, because all the 1980-1988 toyotas didnt have fuel filters on them. Just go buy one cheap from your local hardware store, and install it on your fuel line.
This same thing happened to my 1987 toyota 22r pickup truck.

Hesitation and backfiring


sounds like maybe you have some trash in your fuel tank. Try changing the fuel filter and cleaning the carb. If the problem persists, you may have to drop the fuel tank and have it cleaned out.
