sometimes car starts sometimes it doesnt(dc2)
Obd2a integra....
So sometimes I will go outside and attempt to start it. The main relay will start fuckn clicking before it starts. It doesn't attempt to crank or anything..... don't think its the starter because when the car does finally start my clock always messes up and I have to set the time. I'm obviously losing power, but can the main relay do that to my car and be the problem?

Re: sometimes car starts sometimes it doesnt(dc2)
Check for a bad ground or a broken battery cable clamp, or corrosion on one of the main battery or distribution terminals. All the symptoms you listed make it sound like a main power or ground has an intermittent connection, or that a main power or ground has something like a corrosion problem that is resisting current flow. The clock is connected to constant power (the clock illumination is switched with the ignition, the timekeeping power is always connected to the battery) so if the clock is losing time then that would point to a main power or ground problem. Basically the relay and the clock aren't getting the voltage they need to operate properly, and if low current devices can't operate properly then high current devices (like the starter) definitely can't. That could be a problem with the low current circuits, and the relay isn't engaging the starter solenoid, or it could be a problem with all the circuits and the starter isn't getting enough current even though the starter solenoid is getting engaged. I've seen both happen, and it just depends on where it happens (at the distribution panel instead of at the battery, for example).
This should actually be easy to track down if you have a multimeter and can make sense of what you find while troubleshooting.
I've actually seen this exact same problem with a few different cars, but the actual cause was different in each car. They all created a intermittent or high-resistance problem though.

Re: sometimes car starts sometimes it doesnt(dc2)
You're missing my point. You're thinking local. Think global. It could be the dash harness, but it's much more likely that it's something affecting multiple circuits at one, and not just because the circuits are derived from the same wiring harness. Don't get wrapped up trying to figure out the individual symptoms. Try to figure out the bigger picture that the symptoms are telling you.
Do you have problems with the headlights, or brake lights, or anything like that?
