What error messages are your OBD giving?

Got power to the ecm/does the check engine light come on on the instrument cluster?

[kirkandsylvia]

Not sure if the 98's have this, but might check the black box under the hood that houses all the relays and main fuses. I think there is a fuse for the computer, but not completely sure or not...Just my :2:

You need to restore power to the ecm it's either a blown fuse or a bad wire somewhere. If the ecm does not have battery power to it it will never run. The basic idea is this key on you get a check engine light which means there is power to the ecm crank it, the ecm will see a signal from the crank sensor, then it will turn on the asd and fuel pump relais which in turn powers up the ignition module and fuel pump. If part one does not happen nothing else will happen

You didn't buy a coil from Kragen did you? I've had terrible luck with their electrical stuff. Anyway, glad you got it running.
