I'm sorry I don't have an electrical diagram for your car, if I did, I'd give you a step-by-step diagnostic procedure for checking the power to the pump.
You're going to need to trace power to the pump (don't forget to check the ground circuit) and find out why you're not getting power or ground at the pump. If you want to pursue this yourself, here's some online resources for you:
I don't like to get preachy, but here goes:
No competent pro would simply throw new parts into a car hoping to get lucky because he'd be out of business in a week with lawsuits up the you-know-what. Don't replace parts without diagnosis unless you like spending lots of money on a car that isn't going to run unless you get real lucky.
Enough lecture, get the point?
Diagnosis is key, that's how I made my money.
