Cb7's mysterious symptoms..

Corroded battery connections can do that. I had a similar issue... turned, but wouldn't start. A push-start worked (manual transmission). I replaced the battery and starter, same result. Cleaned the cables... and it worked perfectly.

One of my Accords did something similar. It would start up fine and be running, and then just quit. Sometimes it would be while it was running, other times I would park, and then it would not start back up when I got back in. It would crank but not turn over. Lights, radio, etc would still work. It would go for days with no issues, and then out of the blue, it would quit again. Replaced the main relay and that took care of the problem.

That's what I though, they bypassed the clutch switch and it apparently had the same problems it's having now before they bypassed it.

I think I'll just replace the cables all together because the ones on it are original and are a bit loose, especially the positive terminal. And they're corroded a good bit.

If you have spark, move on to fuel. I had a Caddy that did the same thing and it turned out to be the fuel injectors. Though the Caddy was sluggish as well and it sounds like yours operate just fine outside of cutting out. Don't rule out the Main Relay though either. Good luck.

So I took it to the shop and they tested the battery and alternator and they said it works just fine, I told them the problems I was having and they looked at me like I was crazy until I took one of them for a ride. They don't have a clue what's causing it either.

When it does not start listen for the main relay . It will make a CLICKING noise from under the dash . I no clicking then i would suspect main relay . I once had a interment no start and when it did not start there would be no clicking from main relay. I fix main relay and problem went away .

Is it possible that it could be a clogged cat chokin down the engine? Because all electrical stuff still works after it cuts off. The interior lights and high beams dim a little every now and then though.

Yeah the main relay works. It clicks when I try to start it. It's like I'm trying to turn the car on when I don't have gas but I know it's getting gas. We checked the whole fuel system, from the tank and pump to the filter and injectors.

I'd bring a tool 8 or 10 mil socket.

Drive around and when it dies unscrew the service port on the fuel rail and turn the key on to see if u have fuel flow.

Check also the ground on the thermostat housing.

Alright, I'll try that. Where's the ground for the thermostat?

[accordztech]

You will see a ground bolted directly on the thermostat. I'm highly doubting thats your issue tho.

Clogged catalysts are largely a thing of the past. Modern catalysts have much better substrates, which both flow better and are less likely to break up.

I have seen pictures of catalysts clogged with MMT (a fuel additive to raise octane that used to be available in Canada). But even here the clogging was only around the edges and the center of the catalyst was still open. It reduced power and fuel economy a bit, but not so much that the driver would notice.

I'm not saying it can't happen. But it is rare these days.

Now my lights dim when I shift and let the clutch out, sometimes it'll dim while coasting. But so far it hasn't cut off or stopped turning over for about two days.

I don't think it is then lol. I've noticed that it cuts off and on when under heavy acceleration, SOMETIMES it'll cut off and back on when cruising around. After it does that if I park it, it'll crank but it won't turn over unless it sits for a while.
