How do i ck if fuel pump defective or no pulse at injector no power.

You have wasted a lot of money buying stuff that is not needed.
Check the pulses from the crank shaft sensor.

Use a noid light or other tool for checking the injector pulse is present.

If injectors have a pulse when the engine is cranked the reason there is no spray is there is no fuel pressure - fuse, relay, pump, wiring, pipework, filter. Water in the fuel tank is also a possibility.

If there is no pulse it could be crank or cam sensor, fuse, wiring or even the ECU.

no signal for the injectors
check cam/crank position sensors
check immobilizer operation
check ecm and harness connections

Is that static pressure with key on, engine off? Or engine running pressure? Both should be near 60, usually key on, engine off pressure will be about 3 or 4 psi higher.
If it runs good after starting, the injector pulse must be good. No reason why starting and running pulse should be different. Only difference is when running, fuel pump power is kept on by the oil pressure switch, whereas in starting, the fuel pump relay keeps the pump on. Very unusual, let us know. Measure voltage at one of the injector's power wire with key on. It should be battery voltage or very close.

Which fuel system do you have, spider fuel system or tbi? Check for proper fuel pressure. Check fuel injector pulse.

If you have the spider fuel system, that system is noted for problems. Any applicable trouble codes? If computer doesn't see an rpm signal, no injector pulse, no fuel.

I can't rule out a problem with ignition module, but, there could be other issues?

injector pulse is conrolled by the computer and the spark is controlled by the inghtion mudule. even though the spark is happening the computer gets it's pulse information for the inghtion module too. So the ingtion module ( in the distrubutor ) can be bad on the injector circuit. If the fuel pressure is too low the fuel won't flow either. On Vortec engines the fuel pressure has to be 50 PSI or higher or it won't even start. The throttle body engines have to have 20. If not the fuel pumps hose inside the fuel tank may have a whole in it so the pressureized fuel from the pump just leaks back into the tank as the pump is in the tank. This happens alot. The injectores ( in the throttle boby) ( you did'nt mention the engine in yopurs) should have power on the one wire with the key on. The other wire should have a pulsing ground as the engine is cranked. To test this, connect a test light to the battery positive and the pointer to the wire and crank the engine if the light flashes the circuit is good and if the power is good this circuit is'nt the cause of your problem. On the throttle bobvy engines theirs a tap in the fuel line going to the the throttle bady near the back of the intake. a pressure gauge can be connected here to check the pressure. some don't have this fitting and you have to remove the fuel filter and put a tee connection wher the filter was and check the pressure there,. The fuel filter is inside the frame rail on the drivers side 1/2 way down the side on the truck, towards the center of the truck. Fuel pressure is a common problem.

You have 35 psi of fuel pressure and injection pulse?

Just because there is fuel at the injectors doesn't mean there is any fuel pressure. You need to check your fuel pressure and if is low or non-exisitant then you either have a clogged fuel filter or a bad fuel pump.

is there power to the injector, do the injector inject fuel

is crank sensor signal ok

Check the pickup in the distributor as this is the cam sensor. The injectors run of the pulses created while the rotor is turning around. It should be a plastic disk located under the rotor button.
