1995 Geo Prizm starts, but stalls when put into drive.

why did you put in the pump.
we need the reason for that first.
for two what ?(days, weeks , years?)

there are 3 states,

1. cranking robustly
2. engine starts
3. engine runs and sustains running, not stalling.

where does yours fail.

????
or was driving and it stalled or stalled and cant start (1,2,3?)
tell more get more.

sounds like a blown head gasket. lust one over heat can blow a head gasket

is the ac commpressor locking up???

If fluid level's are good, where they should be, then it sounds like you got a bad transmission, sorry.

I would try using a fuel system cleaner from the auto-parts store and change out the fuel filter. The gas additive will help clean out the fuel injectors and the fuel filter maybe need to be changed anyway because of the age of the vehicle.

A clogged fuel filter would cause this problem.

I think i have air in my clutch line and it is going to the floor my fluid was low now my clutch is working a little here and there. how do i get that air out of the line?

EGR That The problem. check engine light on code 71

might be dirty fuel causing it to sputter

my first car was a 69 dart with 340 hi pro 4 speed bad *** car
