i started my 98 grand last week and went inside to let it warm up. when i came back out 5 min later it had stalled. it will turn over and over and its getting fuel. the engine computer and coil have been replaced. what am i not seeing? there are no check engine lights on. please help

 

There are only four things that make an engine run. An air/fuel mixture, an ignition source, compression, and having those three timed correctly.

I assume it didn't jump time and, therefore, has no compression problem. You say that the fuel pump and injectors are working. Then you need to check the ignition system for spark.

 

Pull one of the plug wires and check for spark. Put a screwdriver in the end of it and hold it close to a good ground and have someone crank it over while you watch for a good spark. Report back with what you see.
And Welcome to CF!
