93 Legacy Fuel Pump & Starting Problems

If it runs good when first started, and can run 70+ mph, then the pump would be putting out plenty of fuel.
Have the codes pulled, maybe you have some sort of temp or O2 sensor problem.

It's a temp sensor or crank angle sensor problem.
Maybe the bypass valve on the throttle housing to.
Since the check engine light comes on there are fault codes in the memory.
Temp. fault code is 21.
Crank fault code is 11.
Bypass valve fault code is 24.
Feul pump is inside the tank, under the trunk floor on passenger side (LHD) just behind the rear seat. (but also I dont think that's the problem)

I forgot to mention in my earlier post...If I unhook the battery for an hour or two to reset the computer, check engine light goes off and the car will start up fine and sometimes run for a day or two with no problems until the check engine light comes back on....then its back to where it idles strange and wont start, etc.

It does sound like a coolant temp sensor.

I would try replacing the temp sensor (cheap) before putting all that dough on a new fuel pump.

It's not complicated but a little difficult to reach. It's under the passenger side rear intake plenum. It screws horizontaly towards the front of the engine. Sart looking at the PCV valve, go down from there and towards the front of the engine under the intake plenum.
What you'll have to disconnect to get free access is intuitive.
You'll nee a ratchet extension preferably with a swivel joint.
Hope that helps.
You could also get a second reading of your ECU fault code by someone else. To be sure.
