Mass air flow sensor maybe drity or going bad . Ever had it replaced ? Have you replaced the air filter lately ? Video's on youtube showing how to clean mass air flow sensor , you would have to buy a can of mass air flow sensor cleaner . Also while your at it clean the throttle plate , again there are videos on youtube . How did you check fuel pump ? To do it right you would need to hook up a pressure gauge . Also check flow .Videos on youtube .Has the check engine light come on ? Also you mite try some fuel injector cleaner and or dry gas for moisture in the fuel !

Testimonial: "Thanks Jeff, It ended up being the fuel pump, they checked the line for pressure, it had 30lbs, suppose to be 50.........lol"

05 taurus spits and sputters on startup when cold

This can be caused by a problem in the fuel pressure check valve of the fuel pump. Have a pressure leak down test run by a shop, if the system is losing pressure then the pump assembly must be replaced. The fuel pump is located inside the gas tank and is electric

95 chevy g20 van started to lose power while driving and began to spit and sputter

Ck your alternator output, should be between 13.8 and 14.2 volts, A bad alt will cause the battery to discharge when driving, Once voltage drops to a certain level (9.8 I think ) the ecm starts to shut down causing all kinds of strange problems, like running bad ,trans not shifting right, even the radio ! It happened to me in my 95 chev p/u

2005 Astro van Head lights - How can I modify factory setting to turn off headlights when car is running?

Try pulling the fuse or the relay marked DRL (Daytime Running Lamps). More than likely each headlamp has its own fuse and relay.

Also, ensure that your headlamps work when you turn on the switch!

Van Sputters And Loses All Power When I Accelerate

Internal combustion engines requires 3 things... fuel, air, and spark. You do not have enough of one or more of these. If the wires and plugs are old, change them.  Air filter, same thing.  Fuel filter can also clog up with stuff after awhile. When you take a look at the air filter check where the air comes from.  It is possible a little critter has built a home and blocked the air flow (rare, but, it has happened).

Engine turns over but will not fire

Probably a bad fuel pump. Known to fail from one turn of the key to the next.
