Is it finding the fob?

Where did you attach jumper cables? Should only attach at the battery, not under the hood at fuse box. You might check to make sure the fuses in the box on top of the battery are good...
Check with volt meter to see if getting 12 volts to the cable to the starter.

Need more info. Do all the accessories work? What happens when you try to start it? Does it make a click noise or anything?

Any messages on the DIC?

If M7, clutch on the floor?
If A6/8 Brake pedal pressed?

Any sounds?

When you jumped at the battery in the rear, any messages on the DIC?
Big *** fuse on top of the battery, if blown, will stop a jump unless you are on the cables directly.

Need a lot more information before we can give any hints or suggested solutions.

"Trolling down the River!!" New member, one post, and the question so general, and generic.

OP, prove me wrong. Answer the questions already asked.

Well, he said the lights come one so the big *** fuse is OK. It feeds the forward fuse panel and starter. Still, many questions to be answered.

Check the starter relay in the fuse box under the hood - relay fuse #54 and the starter fuse #2.

I'm gonna start out with the easy stuff. OP, did you try putting the FOB in the steering column transmitter then hitting the start button? If that works replace your FOB batteries.

He would get a DIC message saying that it does not see the FOB. We're asking questions to see if there are any messages.

So far, he has abandoned the thread so

Rumor has it....

Three and a half years after the question was posted, we heard that after all the advice about jump starting, he electrocuted himself trying to plug it in to a 220 circuit thinking it would give it a bigger boost - RIP

anti theft hack?

Quick question. I yanked these two out and the car wouldn't start. I'm doing this to prevent theft if someone breaks in. If they had half a brain mechanically, could they swap any of the similar fuses or relays already in the box into these places and the car would start again? If so, which additional ones would I have to remove to prevent this. I'm assuming theives won't be carrying spares with them. Also any issues you think it would cause not having these in the car while it's just sitting there or are they fine in my possession while the car is in my driveway at night?

Thanks in advance,
M

No matter what you do, professional thieves will just flat bed it away in a matter of minutes. Some special equipped tow trucks can hook up and be gone in less that 30 seconds and the driver never even has to leave the cab.
