replaced serpentine belt but car doesn't start

you'll find its pretty hard to get the belt to tension up if its on the wrong way

like i said a silly question, some times it can be the silliest and simplest thing

My car had a similar problem and after a few mechanics and Holden a Auto electrician found that a relay was faulty after I replaced the fuel pump and crank angle sensors.

Check to see if the belt pulled of the wiring from your crank sensor located at the back of the balancer / crank pulley
