Re: 1991 ford van
I recomend you to spray little brake cleaner to the air filter do nto do it straigth to the engine and keep adding little by little until it runs normal if you hear any knocking just stop adding spray and look for another soution,
also what you can do is get a shop rag than is just a little humid with gasoline almost dry and hold it rt on the throttle and have some one cranck the engine, be very carrefully because it **** a lot of air and migh **** the rag

Likely a gas or spark problem. Spray starting fluid into the air intake while cranking it. If it then runs for a few seconds, it's a fuel problem-maybe the fuel pump, filter, or injector circuit. Check if gas is getting up to the engine.
Buy an inexpensive "spark tester" at a parts store, and check for spark- if no spark, the ignition circuit will need diagnosed- could be the ignition coil, maybe the electronic ignition module-several possibi9lities. Let me know what you find, or if other questions..
purge valve is just that a valve it puts access fuel vapors back into the combustion chamber for the engine to continue to burn them. there is no filter on it however it could be bad and causing the rough idle
Thanks for using FixYa and welcome to the site Clay. It could be either one of them. The only thing, there are many things that can cause this. Have you checked the fuel pressure? Could be a leaking injector. You could have a vacuum leak. It may be a MAP sensor, the Idle sensor, or the EGR. All of them are possible. What was your codes? I see the numbers but what is the detail?
Well if you ran out of fuel that means the pump sucked lot of air in, and it wil take o while for the pump to deliver the fuel back again to the injectors. and if its a diesle, you might need to purge it.
On a 1991 Ford Thunderbird with a 5.0 V8, the fuel filter is on the bottom of the passenger floorboard just behind the front wheel. Turn the car on and open the trunk. Behind the carpet on the drivers side of the trunk, there is an inertial fuel cut-off switch. This is triggered if/when the car flips over or hits something really hard. Disengage this cut-off while the car is running. It will lower the pressure in the fuel line and the engine will die. Disconnect the battery under the hood. The fuel filter has a splash guard covering it. Remove the two bolts and un-fasten the quick-connects on either side of the filter. Save the two clips unless the new filter came with new ones. Remove the old filter put the new filter on and replace the retaining clips and the shield. Connect the battery, engage the inertial switch, and start 'er up. Should turn over for quite a few seconds until the fuel fills the filter and lines.
The EVAPORATIVE PURGE CONTROL VALVE is located under the hood usually behind or near the back of the headlights. It it on the top of the Evap Charcol Cannister ( shaped something like a Quaker Oats box ) . Basically does not allow fuel vapors to escape into the air. Te purge valve will recycle the vapors through a charcol filter and sent to be reused as fuel., Problem could be caused by excessive fuel in the cannister, or the solenoid, or wiring, etc back to the computer.. Requires a lot of diagnosing. Hope this helps.
