H2 startup issue

[Infantry H2]

Wondering if u guys can help. My h2 is having some startup issues. I go turn the key to on just prior to starting it and everything is good. I go to crank it and it acts like it wants to start but then it dies. The dash lights then start to flash on and off to the cadence of the door chime and exterior lights remain on. Turn the keys to off and pull them out, put them back in and turn it to the on position just before cranking and all is well then try to crank again and the light show happens again when the engine stalls.

Can someone tell or even better show me where the starter is?
How about the fuel pump to change it out? Can I go though the interior under the rear seats?
By the way it's an 03 h2 and i currently have the steering plastics off to possibly check out the ignition switch.
Is there a way to see if the big gray fuses are blown?
I'm rather mechanically inclined just never learned how to fix or troubleshoot this issue.

Thanks in advance.

tap the starter with a hammer.
get under the vehicle thru the drivers side. its circuler and around the tranny a bit.

hopefully someone chimes in i suck at mechanics.
