Fuel punp works but there are two , I do get fuel pumping out at the line at the throttle body. but not being prcessed after that.
If you have fuel pressure at throttle body make sure you have power to (nodes) at top of throttle body that opens to let fuel into motor
I took off the tank and found a tear in the strainer and broken plastic in the tank , I lost the gas cap at the gas station that day and thet stopped the fume pressure which is why it ran until empty without gas at the pump because it was all blocked by plastic at under 4 gallons. It always started running funny at under half a tank but with no gas cap it wont run at all. Believe it or not
Yeah the gas cap broke me down

SOURCE: No Fuel at throttle body
If you think it's the pump ... Find your owners manual to find locations of fuses and relays ... First is this vehicle on level ground? Does it have sufficient fuel level (1/8 tank or more) then have an assistant turn on ignition switch to run position (not start) while you listen under the tank to hear a pump ... it may only make a noise for a few seconds ... is there fuel getting to the throttle body at the input line (it could be the injector) if there is fuel pressure at the throttle body/injector it may be the injector itself) >>>If no sound is heard ... first check for power at following locations >>> Fuses >>> Fuel pump relay >>> harnesses/connectors going to the tank from the front all the way back >>> connector at pump (tank likely will have to be emptied and removed, and you would rather avoid this if possible) >>>pump ... I don't suspect filter, as I've never had one suddenly fail completely

Have you check the injector relay or maybe a fuse for injectors.
SOURCE: throttle body injectors not fiering but there is fuel pressure
the injectors are fired thru the engine cotrol module but it gets its signal to fire from the pick-up located inside the distributor if you are loosing injector pulse only the ignition module is bad if you are also loosing spark when you loose injector pulse your pick up is causing the problem if you replace the pick-up i recomend you change the ignition module when doing so because they work together and you have to remove the distributor to change the pick-up
SOURCE: blew fuse to fuel pump,didnt realize it had blown
there may be another bad fuse, double check, are injectors spraying, if you spray throttle body will it start.
Testimonial: "helpful but not the solution. wont start even spraying throttle body"
