Check the throttle position sensor (TPS) and system vacuum.

Ok first question. Did you install an AC Delco fuel pump? If not, change the pump. Other pumps do not maintain the pressure that is required by the system. You say you have installed a new disturber, insure you are time installed correctly. Rough running usually is a vacuum leak, usually you can find it by spraying cab. cleaner around the intake manifold and components. Hope it helps

Did you bench bleed the MC before installing it? If not, that's the problem. MUST be bench bled or you'll always have air. If brakes lights are on, the brake switch is out of adjustment OR (since you replaced the MC), the push rod is out of adjustment

If it has a Mass Airflow sensor unplug it and see how it runs. If it smoothes out that is the problem. I would also check for vacuum leaks the base of the throttle body is suspect, usually bad gasket

The coil may be starting to fail.

Before starting the engine, the fuel pump should only run for a few seconds when the key is first turned, to pressurize the fuel system. Even though the pump appears to be running, you may either have not enough or too much pressure for the engine to keep running (fuel pump or pressure regulator). I think it may just be a coincidence the engine quit while turning a corner, but the gas in your tank may have been so low it sloshed away from what is likely a very old pump, starving it and causing it to failure.

You need to locate the RPO (regular productiin option) sticker it has a list or 3 didget aplhanumeric codes on it. One code is for the tranny and it should be the only code starting with "M". Transmission codes on a 93307 c1500 4.3 2wd range from M01-M99 and MA1-MY1. You can eather google the code once you have it or send it to me and i can help you find it. The sticker is going to be in driver door jam, glovebox, or under the hood.

check the cable first. It connects into the driver side rear of the transmission tail. Remove the cable from the transmission...
you shoud see a short section that was farther into the trans, and that piece will go into a small plastic gear.
check those for damage.
the end of the cable should spin freely with fingers.
if not spinning, broken off, or the plastic gear is damaged, it's a pretty easy fix.

there is no drain plug. you must undo all the bolts holding the pan in place. After the first few bolts the fluid will start leaking out so have a drainpan under it
