02 Buick Century weird problem..
 

i changed the battery in my sisters 02 Buick Century, now it wont start. heres the weird part.

it has plenty of juice, and i even cleaned the terminals, when the key is turned back to ACC, the radio works, when the key is turned to the ON position, the radio does not come on, and when turned to the START position the dash goes blank like it is suppose to when the starter is engaged.

i have checked all the fuses, each and every one of them, all are fine.

i used a tester and i have power from the battery to the alt, and to the fuse box under the hood, and power at the starter. when i jump the solenoid wire at the starter, motor cranks over, i have no spark or fuel.

its like i never turned the key in the ignition.

if you GM guys got any ideas, let me know!!

Well i got it fixed!
when my boy checked the fuses on the right side of the dash, they were all good.
here the kicker, when the fuse for the PCM,BCM, U/H RELAY (10Amp) was pulled and checked, it was fine, the problem was it was put in the wrong slot, and it was in a blank fuse holder!!
here i was ready to change the ignition switch out, and keep on going till i found the problem.
whats the old saying KISS....Keep It Simple Stupid!!! hahaha

How about the answer to a little mystery? Anybody know how the fuse got put back in the wrong place? Not the guy who changed the battery or was it?
