Well, thats alot of stuff to just break at one time.
check your VSS plug (located on transmission) for rust and crap, make sure its tight. Check for broken wires to either of the o2 sensors or main harness. The O2's are on the exhaust by the motor with 4 wires on them. Did you have an engine fire? Is this a newly installed motor or tranny? maybe O2 sensor plugs reversed. Good luck, if you provide more info I will try to help more

i encountered this problem before on my 99 EX (well, the o2 problem and the ELD problem). apparently (and just my opinion), the ELD can be shorted out if ur o2 sensor(s) go bad. more than likely, u will have to replace the whole fuse box under the hood and the o2 sensor on the bottom of the header.....................good luck man......
