Alright here we go, I replaced my spark plugs and wires at this time I had my battery out. Anxious to see it run, I picked up my battery , placed it in the wrong way and hooked it up backwards(positive to negative and negative positive). I saw a spark and I immediately stopped. Panicked of course cause I knew i did something stupid. Now my car will not start (has no power what so ever) however the brake lights, horn, and hazard lights work which is weird. I have an ECU or ECM from my other prelude (i replaced it to see if it would run, i didn't). I looked at all the fuses under the hood to make sure the mains were not shot (abs fuse seems to be weird tho, what is that?) I put a different battery in, tried it and nothing. What could it be?
It is a fuse stop looking and start testing. Everything in the car except the alternator will survive hooking up the battery wrong.
The sensitive electronic components are likely protected by diodes so you'll need to look and check closely to all related fuses as indicate in the fuses/relay boxes: The under hood box: Fuse # 31 (30A), # 32 (100A), # 33 (50A), # 34 (40A), # 35 (40A), # 36 (50A), # 42 (20A) The under dash box: Fuse # 14 (15A): This is the PCM fuse. Check those fuses, make sure they are good, if in doubt you can buy a DVOM (Digital Volt Ohm Meter) from any auto part store and it's less than $35 to ensure testing the fuses the right way. Good luck to you, there is a fuse you've missed some where. If you need all five wiring diagrams for the Power distributor systems for the car or the FSM. Send an E mail with you E mail address and I'll send it to you. The files are too large to send through YA forum. HTH Edit: One of the five wiring diagrams
