2000 LX wont start

ok well i have a 2000 LX that i am making into a show/cruiser.

the interior is gutted out of the car for wrapped,molding, and painting (including dash). the car started after all this stiff was pulled.

so the car will not turn over at the key. it sends power to the starter relay. but it is not getting the ground from the computer. i changed the computer with a good one. the car does crank over when jumped at the relay, but will not start. it will fire on quikstart. the car is getting good fuel pressure and spark just doesn't seem to be firing the injectors.

Also getting wierd displays on the cluster flashing back and forth between FUSE an NO BUS.
also when i open the passenger side doors the horn starts going.

Thanks Ben

check all your fuses first and go from there. I'm not a wiring expert, but that's where I'd start.

Check all the ground points.

Have you tried swapping out the ASD relay for another one? The ASD relay controls both the coil and injector circuits.

did u install a Sentry pcm into sentry car?

yes i have checked all the underhood grounds, there are 4 off in the interior.

i checked all the relays there all in working order. and the coil pack is working but i didn't think ASD controlled that only injectors.

Yes the computer i swap was a sentry computer and my car is a sentry car. with the new computer i took the immobilzier black box, keys, and lock cylinder.

i have got the problem norrawed down to pin 31 on the computer it is the pin that sends ground to the crank side of starter relay thats why it wont crank at the key. it will crank it i send a ground on this wire. i have checked all the pins on the computer that are suppose to make it send the ground and they all checked out OK

Thanks for the input anymore ideas.
