Check output from relay first, To make sure contacts in the relay are ok. There are wiring diagrams all over the forum
If the pump is just not working because of a little corrosion on the brushes, you can try this.
About 2/3 the way towards the back of the tank. With RUBBER hammer, short, LIGHT, rapid taps to the bottom of the tank. The idea is to VIBRATE (not beat) the bottom of the tank and baffle. To get the pump armature to move just enough to contact a better area of the brushes. Do this while someone else is regulating the key to on and off. Not start. IF STOCK. When you turn the key off for 10 seconds the ECM will reprime for 2 seconds again. So, on, off for 10 seconds, on, off for 10 seconds, on and so on. Also if you can find a fitting to fit you test port on the fuel rail to attach a hose to and run it outside the car into a suitable container. (Highly suggest making sure you have an extinguisher around). This will give your pump a chance to spin up easier without pressure coming up. If you get it to spin, (IF STOCK)than you can jumper the ALDL connector for continuous run. If you can get it to come on, run at least a half gallon of the fuel into that container to help the pump clean itself and get some of the moisture of the bottom of the tank. Then get a filter. Than let it pressure up to try starting.
If this does not work in about 5 minutes, you are dropping the tank.
