I just replaced the ignition module the ignition coil the throttlr positioning sensor and tje coolant temp sensor.on my 1995 pontiac trans sport 3.1. It also has a new battery and it still wont start. Do I need to reset the computer or

What size engine . 3.1 or 3.4 Has two crankshaft position sensors

No, not the oxygen sensor. A couple of things you need to make clear. What light flickers, then stays on? That can't be a sensor light, it would have to be the "check engine light" or an engine temperature light (for like when your cluster has no temperature gauge, but just the "red light").
At any rate, the sensor you changed is not the engine temp. sending unit for the instrument panel. I believe on your '89 there would be two sensors for temp. One is the CTS for the engine computer, and the other is a sending unit for the dash, probably a 1 wire connector. It could be at fault, but it wouldn't cause stalling, I do not think anyway.
If it stalls and won't restart until cooled, this is a symptom of loss of ignition (spark) caused by either a faulty coil, or faulty Ignition Control Module (the coil controller), or last a faulty Crank Position Sensor (this sensor used by computer to determine ignition spark timing). You could test if ignition is lost, by checking for spark right after the engine warms and then stalls. If you have no spark to a spark plug right after it stalls, this is the reason for stalling. Usually it is the crank sensor, rather than the ignition control module or an ignition coil. Your car has 3 coils anyway in a "coil pack", so if one coil went bad, you'd still have two good coils, but engine would only be firing on four of the six cylinders-could easily stall a car.
You should check for trouble codes whenever you have a problem. A code might have been set. Easy to check for codes on your car, just ask if you don't know how-only takes a jumper wire or even a paper clip works. good luck.

Not sure if I am following you right.
The engine has 3 coils that fire the plugs. The coils are mounted on a module that provides voltage and ground to the coils.
The module gets power from a 20amp fuse marked "Inj" for injector.
The computer controls the module based on info from the various sensors.
A mechanic would do a pin test on the module to diagnose a no spark condition.

looks like your wires and melted together or a rodent has chewed them

coolant temp sensor may be bad

Here it a pic of the CTS for the computercoolant temp sensor

(2) Fuel Pulse Dampener
(3) Fuel Rail with Injectors
(4) Crankcase Vent
(5) Left Bank Ignition Coils/Modules
(6) Left Bank HO2S Sensor 1
(7) Engine Coolant Temperature (ECT) Sensor
(8) Fuel Pressure Gauge Test Connector
(9) Throttle Position (TP) Sensor
(10) Idle Air Control (IAC)
hope it helps if you need more info just ask!dont forget to vote on the answer thanks have a good day DB

that is also known as a quad 4 ! you have to take compression tests of all 4 cyl! and check for injector pulse!

Well you hit all the major ones, could be crank position sensor, ignition module, a bad coil pack (it should have 3), you need to check that you have spark to each plug while the engine is turning over (!!!be careful as this will hurt if you get shocked!!!), this will rule out coil packs. if you have no spark to any plug your looking at a bad ingnition module (which is what the coil packs bolt to). Hope this gets you on the right track!

All coil packs are attached to ignition module. Then module should have two wires running to Crank Sensor. If there are 3, then one goes to tachometer
