Engin wont stay running

Have you checked the fuel pump for any blockage? The car isnt getting any gas unless u manually pump it by pressing the pedal.. So start there
Sometimes when a engine requires excessive revving and throttle to stay afloat its a fuel supply problem. A clogged filter for example can be overcome with excessive throttle that drives the fuel pressure up enough to force it through, but it will barely trickle at idle and stall.

Usually the dead give away for fuel pump is when someone complains they have to floor it as soon as it turns over or it will die right away.

Turn over is the process that an engine makes when it is trying to start. If you twist the key and get nothing then it wont turn over. Google shimming a starter and watch the vids.

CAn you describe the problem with a little more detail. Does it start and run for a while before it stalls. Does it start and then stall right away. Is there a pattern to the stalling, turning, going over bumps, coming to a stop, trying to accelerate?

what engine do you have?

is the check engine light on?

insufficient battery power to stay running. replace battery or alternator.

rebuild the carb.

if it won't turn over when it's standing, but will when it's not, then it's a pretty safe bet that it's an electrical short!

try checkin your idle air control. most of the time it is a vacuumn line going into intake.pull it off and if the car revs up dont worry, it wont hurt it. if it does simply put it back on, if it dies you have a bad vacumn.

Check the fuel delivery, first. It could be fuel pump or an obstruction. The best way is to start the car in park, then run over to the engine compartment and rev up the throttle. Keep idle higher than normal. If it wants to die, rev throttle higher to compensate. If it makes no difference, verify fuel pressure when engine dies. Usually ignition related wont even allow the car to start. Any service engine indication?

check airflo sensor or potentometer,throttle pos sensor; if revs are to low when turning the wheel the power steering pump will draw power from engine, causing your other problems
