1994 chevy cheyenne started an ran for few minutes after sitting all winter then stalls now wont start

Can either be fuel filter is dirty or fuel pump is going and there may be a short or burnt wire on the fuel relay. they should all be located in the same area.

Good question. All you can do is hook a line up to the fuel rail to get some gas so you can inspect it. If the gas looks ok they you probably have either a fuel pump problem or ignition problem.

Usually a problem with a dirty throttle body or a faulty idle air control valve. The computer controls idle speed by regulating how much air enters the intake thru the valve.

Check for spark at the plugs and fuel pressure at the fuel rail. This will narrow down our suspects. Then let me know. If you need to know how to do these just ask. Thanks

the ignition mogule is prpbably bad .have it checked .

Take the battery in and have it tested to make sure it is fully charged and is holding that charge and that all the cells are good....letting a car sit for any length of time without starting it and letting it run for a bit is bad news. Batteries will go bad. Gasoline left to sit in a car will "go bad" and can leave a coat of varnish on sensitive injectors, fuel lines, etc... Water and debris can ruin the fuel filter. Check the battery first, put some injector cleaner in the gas tank and you may also want to spray the throttle body with a recommended cleaner before trying to start again. It may also help to pull your spark plugs and clean or replace them. Hope this helps. Good luck.

vacuum leak? or try the fuel pressure regulator my started stalling then got to where it wouldn't crank. changed the fuel pressure regulator and it ran as if it was brand new

Test for weak spark when it wont run....my guess is that its the ignition module inside distributer...they heat up and shut off spark,then cool down and work again for a while...good luck..Lee

Check the sensors on the throttle body. There is a sensor that controls air to fuel ratio. If that sensor is bad then the car will run and then stall out while in drive. I had the same problem when it was cold outside last winter. If you dont want to dish out the money without knowing if it is that part at fault or not then start the van pop the hood and located the throttle body. Place your hand on the sensors and give them a little shake and then make sure they are plugged in all the way. You could also turn the van off and unhook the sensor clean the connectors and plug it back in. That should do the trick and if it doesnt stall anymore then I would replace those sensors if I was you. One more thing. If your giving the sensors a tug while the car is running and you hear it going to stall you could located the gas pedal cable and give it a rev or two by hand so it doesnt stall out and turn off. By the way. You van isnt over heating at all is it?

if this a fuel injected car just check to fuel pressure first.
