My bf's sister's automatic prelude will not start. We thought it was the battery and he went to buy a new one last night. After he installed it, the car still wouldn't start and there is no noise whatsoever when we try to start the car. We checked the fuses and spark plugs also and they were fine. Then we jump started the car and that was the only way that it would start. Do any of you guys know the problem or what else we should look at?

TIA
