Will not stay running

I JUST DONATED 5 BUCKS. I STARTED IT SEVERAL TIMES WITH ETHER AND IT WILL NOT KEEP RUNNING. I DO NOT HAVE THE EQUIPMENT TO CHECK FUEL PUMP PRESSURE. I DISCONECTED FUEL LINE AT TOP OF ENGING. AND AT FUEL FILTER THERE WAS SOME BAD GAS. I BLEW THRU AND IT WAS CLEAR. I PULLED FILTER IT WAS NOT CLOGGED. I TURNED THE IGNITION ON NO FUEL OUT FO TANK, I TRIED STARTING AND NO GAS PUMPED OUT OF TANK. SO I AM THINKING FUEL PUMP IS BAD.

I look at your article and read my service manual. I must test with the motor running to get a pressure. As I stated I can only get it to run with a ether shot, its not getting any gas to hold any kind of an idle for any period of time.

Ok its a 4 cyl 2.6 i-tec. I followed manual procedures. I disconnected the fuel outlet hose at the bottom of the regulator and connected the fuel pressure guage to the outlet hose. Turned the key on and nothing happened, turned motor over and nothing happened.

OK I disconnected the fuel pump plug found I cold not make good contact with ends of wire at plug. I bared each wire (2) used a digital clamp meter turned to the setting w an ohms symbol (4000) put one probe at at each exposed wire and the meter sounded (ign on) I the used a test light (clamp attached to neg post of battery) probed each wire with ign. On but it did not light up. I then went to fuse block ther is 2 20 amp fuses one listed as fuel pump the other listed as fuel pump(st) with test light(circuit tester) clamp attached to the battery ground touched probe to each fuse and both times light lit. Found a 10 amp fuse listed as fuel pump relay coil(b)touch probe to this and light did not light up. I tried a new 10amp fuse and still did not light up. I am nat sure how to test relay. I also plugged fuel pump wires back together and turned ign on went to tank and did not hear anything.

I switched with the a/c relay (Same part number) no noise at gas tank, the 10 amp fuse (fuel pump relay coil) still no light with circuit tester (clamp on neg. Terminal) ign. Was on

Ok I pulled relay and wth the ign on only the center plug lights up the circuit tester that is clamped to the neg post. There is 5 total plugs or spades whatever you call them thabk you for your time

I donated another 5 bucks (total of 15) replied with the answer to jacobnickolas and have not heard back that was 8 hours ago, Whats up?

Hi: I am confused ( there is a surprise!) Your schematic and my manuals schematic and the isuzu wiring do not match.I have 2 relays one in the fuse block and one under the dash(i think its the one) I have two twenty amp fuses and one 10 amp fuse.
One 20 amp fuse is on the fuse block as #23 fuel pump (st)
the other 20 amp fuse is listed as # 24 fuel pump
the 10 amp fuse is listed as # 12 fuel pump relay coil (b)
your drawing and the manual do not show the 10 amp fuse or one of the 20 amp fuses (#23)
the wiring colors do not match up.
The #24 20 amp fuse has a white wire and a blue with white stripe wire
The #23 20 AMP FUSE has a black with blue strip wire and a black with a white stripe wire
the 10 amp fuse has a white with blue stripe wire (just one wire)
the relay at the fuse block has
a white with red stripe
a black with blue stripe
a black with yellow stripe
a black with red stripe and red rings
a black with red rings

the relay in the cab has :
a black with red ring ( qty 2 wires )
a blue with red strip
a blue with orange stripe
a green with orange stripe with red rings
a black with red ring

I bared the ign wires
a white with black stripe
a black with yellow stripe
a black with red stripe
a blue
a black

the fuel pump has a black wired and a black with yellow

Can I just wire a circuit in bypassing everything?
