thanks again for your informed replies, i have an update, as stated before I'm not to familiar with these cars and am just going be the research i have done so far, i think the pump has been kicking in this whole time i didn't know the pump only kicks in after the key is turned to start, i was only turning it to 12 volts and expecting to here the pump, "like on my own car" the car starts when it wants to after many tries, when its running it feels great, no jerkiness or hesitation, then after a while the car just dies and cuts off with no warning at all, any ideas would be greatly appreciated, thanks again.

thank you for the reply, when i put my finger on the rely and have someone attempt to turn the car over the car cranks strong and i can feel the relay pop which i assumed means its good, i also switched it out for another relay in the fuse box of the same specs and still no power to the pump, how do i go about spoofing the relay like you mentioned? this is family members car so i don't know it like the back of my hand, just trying to do the best i can, if theft deterrent was on would the car still turn over? thanks.

hello, have a 1999 es300 that's getting no power to the fuel pump, I've checked the efi fuse and cir opn relay and iv also checked the pump with 12v directly to it and it fires right up, that leaves me thinking there's something wrong with the fuel pump ecu, if this is correct exactly where is it located and is there a test i can do the find out if its bad? thanks.
