Check and clean Idle air control valve. Make sure its responding to signal as well. Also make sure ther are no vacuum hoses disconnected. This may not be a "cure" but it's a good place to start.

SOURCE: car wont stay running unless foot is on the gas

Withoutknowing if the check engine light is on it could be a variety of things including but not limited to the o2 sensor, throttle positioning sensor, and the MAF and MAP sensors. Best diagnosed by using an OBDII scanner to scan for codes. If no codes are present I would then check for the pressure coming from the fuel pump to make sure it is still functioning.

1989 ford f350 diesel 7.3 will start with starting fluid but wont stay running


Never, ever use starting fluid in your diesel.

Taken from the Owners Manual - Diesel Supplement:

Do not crank the engine for more than 30 seconds at a time as starter
damage may occur. If the engine fails to start, turn the key to OFF and
wait 30 seconds before trying again.
Do not use starting fluid such as ether in the air intake system (see Air
Cleaner Decal). Such fluid could cause immediate explosive damage to
the engine and possible personal injury.
Do not add gasoline, gasohol or alcohol to diesel fuel. This practice
creates a serious fire hazard and causes engine performance problems.
1. Make sure all vehicle occupants have buckled their safety belts. For
more information on safety belts and their proper usage, refer to Seating
and safety restraints chapter in the owner guide.

1992 Ford Ranger XLT V6 wont start without ether


first go to an auto partstore and have the code checked. most do it for free. could be coil, fuel pump, fuel filter, air filter or even a bad gas cap. but the dianogstic test should pin point the problem.
