97 accord ex won't crank over
Hi all, I'm troubleshooting my brothers car for him. 1997 honda accord ex, 4cyl, automatic tran. He pulled it into driveway and next day it would not crank over but the lights and radio work. I hooked up jumper cables from my GMC Denali and still nothing. Only one little spark when I hooked up the cables. I could never get the cables to spark after that. Voltage at his battery with the jumper cables hooked up was good at 13.4volts dc.
I pulled the connector(negative side, the other connector looked like it was bolted on) off of the starter selenoid and tested the voltage at the starter selenoid and it was at 13.4 volts(jumper cables tsill hooked up and denali running). I had him turn the key at that point and the voltage dropped to zero or near zero.
It can't be the starter or selenoid because because they were not hooked up. It does sound like it is shorting out somewhere when the key is turned. Does this vehicle have a pcm or relay somewhere?
He needs his vehicle for his two part time jobs, one of which is working for Meals on Wheels of MD managing(only $11hr) and delivery food to disabled people who can't get out to get food by themselves. I trully appreciate in advance to anyone who can offer advice.
