Changed out pumps but car was sitting for 1 yr cleaned tank out filter replacement plugs wires air filter acts like not getting gas still removed gas line at filter had wife hit key no gas checked relays has holes for 5 pin but relay only has 4? Any ideas ? Cam sensor,pump relay ,or pump?

I'm a bit lost on a few things here. You say you changed out "pumps". What pumps did you change out? Fuel pump and what? Also, there are several filters on your car, which did you change out? Fuel filter in addition to the air filter? Have you checked for power to the fuel pump? The relay only have 4 pins is not a concern since it doesn't need to make contact with anything when "off". Two pins are for the coil, two pins are for the SPST switch.

What you need to do before anyone will be able to offer much help is make some voltage measurements. If you can pretty easily get to the connector on the fuel pump, check for voltage there. Use a test light so that you provide a load on the circuit. A multimeter has too high of an internal resistance to identify high resistance paths that would limit current to the fuel pump. If you're not able to easily get to the fuel pump connector, then confirm you have power to the supply side of the relay switched contacts (usually labeled either '85' or '87'). If power is present there, then confirm you get voltage and ground to the coil of the relay when the key is turned to the Run position. This voltage may only be present for a second or so after the key is turned to Run. The relay coil is often labeled as terminals '85' and '86'.

Report back with what you find.

Fuel pump Spark plugs spark plug wires air filters oil nNew fuel filterew battery Car sat for a year so that the timing was off some of the timing is messed up I'm going to Check that next

well if you really have put in a fuel pump correctly, proper fuel filter. and still not getting fuel, I can still think of a few things.

1. a 4 5 post relay is dependant on design, usually 2 posts are the switch circuit and 2 posts are the relay circuit, the 5th post is a 2 way switch.

2. have you checkd the CRANK SENSOR engine takes it's cue from that.

3. low fuel pressure in a fuel injected engine can be blamed on the FUEL PRESSURE REGULATOR wich can be diagnosed with a fuel pressure gague (wich most don't have) or a simple pair of pliers carfully closing off the return line.
