Not sure how to do that
Customer: replied 10 months ago.
It sounds like its not getting fuel
Expert:  Tims Auto Repair replied 10 months ago.

ok,,if it is getting a spark,i would think you are right,it isnt getting fuel...

Expert:  Tims Auto Repair replied 10 months ago.

but,sense the fuel pump does come on,,this tells us you arent getting a fuel injector pulse

Expert:  Tims Auto Repair replied 10 months ago.

the injectors arent openng to let fuel into the cylenders

Expert:  Tims Auto Repair replied 10 months ago.

i dont see anything you could have done to cause this by replacing the belt

Expert:  Tims Auto Repair replied 10 months ago.

but,from the way you explain,,it sounds as if your problem may be bad crank sensor
