SOURCE: My 1990 Camry jerks and sometimes stalls
The 1st thing to do is have a trouble code retrieval test run to see what is making the check engine light come, this is the source of the problem.
SOURCE: My 1991 Toyota Corolla had it's fuel pump replaced 3 months ago.
Yes. may be filter. But first check fuel pressure at injector rail. Should be approx 40 PSI. any lower will cause these symptoms.
Replacing fuel filter should be a given when changing pump, get it changed today.
SOURCE: 1995 GMC Sierra 5.7 liter stalls and is hard
even though parts are new they also come with defects so it sounds as if when you turn the key you hear it working and other times not at all hmmm connections are tight ? could be faulty fuel pump or relay .
SOURCE: my 2001 toyota corolla stalls out when cold
It is registering engine too lean due to either too much air entering the engine via an intake leak or by an inaccurate reading from the MAF.
Often on these cars, particularly if they have used Toyota brand air filters, the MAF collects fuzz over time from the air filter.
As this 'fuzz' collects on the MAF element, it acts as an insulator and skews the airflow reading for the ecm; it sees less air than is actually going through, so when it checks your mixture on the way out of the engine it realizes that there is more air than it thought was going in.
Pull your MAF out of the air hose (two philips screws) and clean it with non-chlorinated brake cleaner or "MAF cleaner" available at your local parts store. Look in there with a flashlight, you will see a little coiled wire covered in little bits of fuzz before you start.
Do NOT touch the element, just use the cleaner to blast it clean. Let it air dry completely before reinstalling.
Clear the code and call it a day!

Hi! As a first course of action please check on the vacuum hoses. If theres unconnected or worn vacuum hoses the idle will be too low. Please check very carefully. Hope this helps and thank you for using FixYa!

Engine
stalling issue at low speeds
This problem
is commonly caused by a dirty automatic idle speed control valve and
throttle valve. Buy a can of throttle valve cleaner from NAPA or
Carquest (made by CRC chemicals) and spray it into the air intake
while the engine is running, use up about 1/2 the can, engine will
try to stall hold the speed up, shut it down and let it soak for 30
minutes, restart and blow out the remaining fluid, shut it down and
disconnect the negative battery cable for 5 Min's to reset the base
idle control
