Default 06 Suzuki Forenza. Front end crash, Cranks but no start. HALP!

So hello wonderful people of the Suzuki forums. I'm posting/will be digging for a friend of mine who recently had a fairly nasty car wreck. she hit a fence and the support cables of a power pole, cables dug into the hood, core support crash bumper and bumper itself. I'll try to get some carnage photos but long story short me and her family plan to piece this car back together into a good solid daily again. Now before the crash I had only heard of it not catching one time due to the driver not cranking long enough. But after this wreck it will not start at all. It will crank, it seemed to have Fuel pressure when I pushed the valve on the rail and otherwise seems as if something like an inertia switch has been tripped.

Problem is, I cannot locate one. Now the rad is smashed up to the engine and the fans are toast so my plans are to remove that one weekend and just for testing try to get it to start and run. If and this is IF I can I need to run it through some gears make sure it all works then I can go about bending fixing, cutting and welding the core support back together as well as getting the other parts and pieces. The fenders headlamps and everything else are perfectly fine by the looks of things.

Anyways I need an idea on where to start with this thing. I'm no moron by any means. I've fought EFI vehicles of my own From a sentra to a F-150 from the old days of Speed density to newer MAF vehicles so I'm good there. I just need to know where to start, what to check and if there is something silly I missed.

Thank you all in advance.

Shadow.

You need to find out if it is ignition or fuel related... (pressure at the fuel rail is not sufficient)...

Do the COPS fire??

Is there FI pulse?

Coils I'll check here in a few days when I go to visit again. Of course I will report back. What would be a good way to check for Injector pulse? I assume a test light into a probe with someone cranking it over?

Be careful, if you are not familiar with electronic circuits, best to use a NOID lite, less obtrusive and will not back feed the ECU.

That goes for all testing, especially with test lights..

That chassis is unibody, have you determined the safety of the structure.
