Aerodeck issues on start up

If your inlet pipe was loose and the b series engine has any sensors that measure air from the intake before the end of the throttle body, that could have been the problem all along. Ludes don't have any sensors before the throttle body though, so I'd be surprised if a B series does... Pics of the intake side of the engine?

As for the thermo sensor, it's a sensor not a switch, I.e. it's a linear change in resistance rather than just on/off. Don't just swap it - measure the resistance when the car is cold and then as it warms up, you should see the resistance change.

Are the dash lights flickering when the ignition is on, or when you turn it to start?

All of the above, and when I'm sat in the house with the keys in my pocket having a cup of coffee

Thanks for that, I'll give that a try tomorrow (if I ever get the electrical fault sorted).

What, the dash lights are on when there's no key in the car or anything?

If so, that's a main fuse box fault. Water ingress or tracking because it's overheated etc.

That sounds fun to diagnose, I'm gonna concentrate on getting the accord running this weekend so I have more time to fault find on this.

Iain beat me to it... Sound like water ingress for sure. And yeah, I hate that

Right, small update, I left the aerodeck over the weekend while I got the accord back in one piece but on Sunday I replaced the battery terminals and found that the fault was still present, no surprises there. The car did however start up and I was able to move it to a better location on the drive.

That night I went to start it up to see if it would be ok in the morning for work and it had ran the battery flat. So, claire called the aa out on Monday morning and had it recovered to the dealership where she works. The aa guy suspected that the ignition switch was at fault as did the techs at Claire's work. Anyway they charged the battery for me and it drove home no problem. It's since sat on the drive as I was working 12 hour day shifts although it has been moved a couple of times to get other cars in and out of the garage and each time it has started no problem.

I'm on nightshift today so have started to remove the ignition switch from the spareodeck and have moved the aerodeck back in to the garage but again it started without fault. I'm going to fit the spare switch now but if it isn't currently faulty I'm not going to know if it has worked until it a, breaks down again or b, it doesn't. Hopefully the latter but how annoying to have to drive around in this horrible weather no knowing if your car is gonna die at any moment.

i would not fit it until it does die again just keep it in the car with the requisite tools

Yep, what merc says for the ignition switch. In fact, if you get the situation again where the dash lights are flickering with switch off/key out, if you've kept the steering column stripped down ready, then just unplugging the ignition switch should tell you if that is at fault or not.

I would though still definitely pull the fuse boxes out and check them now anyway, as a matter of course.

Too late I'm afraid, switch has already been changed. I couldnt have done that anyway because as soon a the lights come on it runs my battery flat.

I guess I'm gonna have to do that now though as it happens again tonight when I went to set off for work. Battery flat again
