Most vehicles have a "port" where you can connect a fuel pressure gauge. It usually looks a lot like a tire valve stem, but make sure it's the fuel line and not the AC. If you connect the fuel pressure gauge then turn the ignition switch on, the gauge should show normal fuel pressure. If it doesn't, either the pump is bad or the filter is blocked. This model has a habit of breaking the power feed wire where it goes into the tank. Do check to make sure it is intact.

Most likely a bad sending unit. Buy one off eBay for $35-$40 and drop the tank and swap units on to pump or buy from the dealer with the pump for $200.
