1998 chevy cavalier starts up then immediately stops.

What have you checked so far ?
Spark to the plugs ?
Fuel pressure ?

All transmissions in all types of cars have some sort of fuse. So, yes, there is a fuse in the transmission of a 1998 Chevy Cavalier.

need to pull codes from computer see if it throwing any codes out

One of several issues will present this problem.
Bad fuel pump = check for fuel pressure and power to pump replace as nessassary
Plugged fuel filter = change fuel filter
Alarm system activated = disable or deactivate alarm
There are other possibilities but you need to start with these

I am sure it's not the transmission. What you are describing is an electrical failure probably a bad ground. The best I can doo with out seeing the car.
I hope this helps.

try to start the car, than the anti theift would shut the car off. you wait ten min with the key on, until you see the anti theift flash or disapear. than turn key to off position and try to start it. this will reprogram the computer.. Good luck.

you can also try disconnecting the battery for 30 minutes

first is it getting fuel ? try shooting a little gasoline or starting fluid into the air cleaner and see if it will run ? if so it is needing a fuel filter or a fuel pump replaced... thanks and holler if you need more Jerry

Sounds like you are getting power to everything but the engine.
Was there a ground wire to the head that you may have left off ?
Hope this helps
