Battery Relocation - HELP!

[88-16Tconv]

I've moved the battery to the trunk and now the car won't start. What the hell have I done wrong?! Pos. cable run from the battery to the starter, smaller constant power cable run from junction block on right side fender to the starter, and battery ground through the trunk floor to the rear bumper bracket. When I turn the key to the on position, my lights and gauges and stereo turn on, but when I try and start it, nothing happens. I have tried a few different ground points all wire-wheeled down to bare metal so I don't think thats the problem. Is there something obvious her my dumb!@# is missing?!

It's definately the ground, I reconnected the original neg. cable and ran jumper cables from it to the neg on the battery in the trunk and car starts no problem. I have a spot on the trunk floor ground down to bare metal where the battery is grounded with 2 gauge wire. All the accessories turn on but the car won't start, won't even click. Is there a sure fire spot for a good ground (it's a 'vert by the way)?

There is no problem with grounding the battery in the boot (my 99T is running like this). It sounds like you just need to work hard to find a decent ground point.
You havent also disturbed the ground between the engine and chassis at the front when you were shifting yours have you? The starter will really need this. To test it try putting your jumper cable between the engine and the chassis and trying your new battery again..

Do you have a good contact on both the ends on your new boot -ve cable? and have you bolted it to you new cleaned up earth point really tightly?

As I have a stereo-cable running all the way in the car to the boot, I'm pondering over just using this cable as my positive cable...
How large a gauge do you think is needed?

I'm running 0 gauge mutlistrand wire. This connects to a kill switch, and then to the electrical distribution block. If the kill switch will keep the car from starting while off, but once the car is running the kill switch does nothing but isolate the battery.

Battery connection at battery switch: Couldn't post pictures in last post.

Is that kill switch only to the starter, or does it cause your stereo to reset also when you use it. That is the one reason that I would not get a battery kill switch, but i suppose you could just run a separate smaller wire to the electronics.

[allessence]

yes, it cuts all power when switched off. On a competiion car sometimes the switch has to be accessible in the drivers compartment.

By the way I grew up on early SAABs 2strokes, and V4's . None of which had a radio. I guess I have gotten used to it because I listen to the radio in the C900 once a month if I remember to turn it on.
