You are going to want to check all inputs to the main relay, when this happens. It might just be bad. With the key in ON position, you should have three powers and one ground.
If all three powers and one ground are present and the relay is not energizing, the relay is bad and will need to be replaced.
Other possibilitie, in this point could be the Inertia Switch which does not give a warning,.other
component problems usually register in your onboard computer and turn on your "check engine" light on the dash. This Inertia
Switch (also called Shut Off Fuel Pump switch) may have shut off power to your fuel pump. It may be on the side of the
trunk beneath the carpet or under a kickpanel by your feet. The part
has a button which needs to be pushed to reset it (hold button three seconds and you should be good).
Keep us updated.
Hello and welcome to FixYa!
It should be working by now for you have good pulse in the injectors plus the fuel pump is new. I suspect that the fuel tank and line is clogged with dirt and rust. I suggest that you drain out the fuel to get rid of the clog then try to fill her up with new fuel.
Hope this helps and thank you for using FixYa! Have a good one!
Regards,

Is this vehicle has a distibutor if so then change the ignitor/coil.
Change your fuel filter - enough clogging can prevent fuel flow, and it sounds like you have a fuel delivery problem rather than an issue with the injectors firing. The other culprit would be the fuel pressure regulator. That's what will allow line pressure to be sufficient for the engine to run. Either a failed regulator or a broken vacuum reference line to the regulator would cause that.

this is not a sufficient asnswer I'm already getting spark and car will crank if I pour gas
in each spark plug the problem can't be the coil
all that was replace when I put new fuel pumb and strainer on the car...
but I notice that only one wire leading to injectors have voltage and this is the black and white wire, the yellow wire has no voltage... but all are pulsing...could this be the problem and does it mean the EMC is bad?

the car cranks and runs when I pour gas in the plugs until I shut it off then it will not start until I pour more gas in the plug holes
the fuel pressure is 40-45psi and regulator is
holding at 40psi when not running...so it's not the pressure regulator nor the fuel pump.
the injector are pulsing fine when running but
are they suppose to pulse doing cranking and are both wires to the injector suppose to have 12volts at the same time?
no no no the car runs fine when I crank it by pour a little gas in the plug holes the put plugs back in,
something is not allowing the injectors to pulse on initial start ...and pressure is fine and holding at the rail..40psi holding when car is off. you can hear the injector pulsating when car is running.
what makes the injectors pulse when initial start up...all are getting signal I use the noid test light.
not happy with your solution ...
