for the love of god someone help me

ok my pump is turning on but not pressure wut could be the problem it turn the key to on or run and i hear the pump come on i try to crank it and there is no fuel pressure what could this be.

 

Where are you checking to see if it has any pressure? if your checking it after the fuel filter there might be somthing cloging it.... just my .02

 

no i guess i wasnt clear the pump primes but when i crank it the relay keeps clicking and then i stop cranking it and the key is back to the on position it primes again so idk wut the problem is i replaced the ecu i replaced the main relay the pump is good or it wouldnt pump. wut could it be oh yea and the filter is still farely new and im gettin fuel to the rail just not enough

 

There is a main relay harness test in the service manual. This will verify the voltages to the fuel pump in each ignition switch position. I am unabe to post the page but it goes like this.

1. Keep the ignition sw in the off position
2. Disconnect the main relay connector
3. Check for continuity between the BLK wire in the connector and body ground.
4. Attach the positive probe of voltmeter to the YEL/WHT wire and negative probe to the BLK wire. Battery voltage should be available. If there is no voltage check the wiring between the battery and the main relay as well as ECU fuse (15A) in the maun fuse box.
5. Attach the positive probe of voltmeter to the BLK/YEL wire and the negative probe to the BLK wire.
6. Turn the ignition ON, battery voltage should be available. If there is no voltage, check the wiring from the ignition switch and the main relay as well as No. 14 (10A) fuse.
7. Attach the positive probe of voltmeter to the BLU/WHT wire and the negative probe to the BLK wire.
8, Turn ignition to the START position. Battery voltage should be available. If there is no voltage check the wiring between the ignition switch and main relay as well as No. 2 (10A) fuse.
9. Connect a jumper wire between the BLK/YEL wire and YEL/BLK wire.
10. Turn the ignition ON. The fuel pump should work. If the fuel pump does not work, check the wiring between the main relay and fuel pump, and the wiring from the fuel pump to the ground (BLK wire).

Looking at the main relay connecter the 2 rows with each row having 4 connections:
The diagram in the service manual shows the following wires:

Left to right looking at the connector:

Top row is:
--BLK-- --BLU/WHT-- --not shown-- --not shown--

Bottom row is:
--YEL/WHT-- --not shown-- --BLK/YEL-- --YEL/BLK--

If your voltages are ok and the pump is running in the prime and on positions then you may want to look at the injector resistor and/or the pressure regulator. If you disconnected the pressure regulator (don't know if you did) there is a small O ring that is recommended to be replaced when you do so. If it inadvertantly fell out you will have problems.

Hope this helps.
