Overheated how bad ? Fried the engine , check compression ! Check to see if it has spark at plug wire ! Fuel pressure ! No there is no sensor that would cut off the engine .

Testimonial: "Got compression and spark and juice , put new ignition module and and distributor on it as the coil wire on distributor was broken, also put new cap and arm and leads and plugs , it backfires like once on turnover then nothing , thanks"

    on Dizzy LOL first time i heard it called that ! That's right #1 at seven O'clock with a clock wise rotation !

    Does it have a mass airflow sensor or map ! Try checking five volt ref. voltage. At the TPS sensor .Do you know what 5 volt ref voltage is ? Engine computer supply's 5 volt ref voltage to some sensors on the engine , tranmission . If less then 5 volts a sensor could be shorted, bring down ref. voltage circuit inside the PCM - engine computer .This would cause no start condition . There are three wires at the TPS . Disconnect the connector and check to see if one has five volts . The other two are a ground and signal to PCM

    Also , does the check engine light come on when you turn the key to the on position ?

1998 firebird 3.8 v6 92000 miles runs great until 3000 rpm then it runs rough and starts to miss

Same thing happened to my 94 firebird. Did your car run hot at any point? Mine overheated and ended up melting a couple of plug wires.
I replaced the wires (and plugs). That took care of the problem.

Is the engine from the bonneville a 3.8 too. If its is it will interchange, Just make sure you use everything off the 98, like all the sensors ect. The basic engines are the same its the add ons that will be different.

Overheating, no coolant loss

I have a 1996 Pontiac Firebird with the 3.8 L V6, and have had problems until I replaced the DexCool (it's never ran so good!) However relating to your problem, there was a class action lawsuit regaurding the 1996 GMC/BUICK/PONTIAC 3.1 L engine, due to DexCool destroying the engine/heads/etc. Follow the link - I do not know all of the details, but it may be worth checking out. 1996 was the first year that DexCool was used at GM.
Hope it helps.
