I have a 1997 Acura 3.5RL. One day I was working on the car and listening to the radio. I cranked it up to make sure the battery wasnt dead, and it cranked fine. Then i cut it off for 10-15 minutes and when I tried to start it again, it wouldnt crank. It turned over but it would not start. I replaced all the spark plugs, the coil boxes, replaced the computer, replaced all the relays. Made sure the fuel pump works and the fuel filter is new. I don't know too much about cars and I cant afford to just take it to the shop. Does any one know what might be? It tries to start, makes the "ruh ruh ruh ruh" sound like its going to start, but never actually turns over. Ive tried jumping it off thinking it might have just been low battery or something, but it wont jump off either. I appreciate any help anyone can give me.
