    I am really at a lost!! I talked to a friend who works on only hondas and doesn't know what to sugguest. He says he never had one like this. He says if the PCM were bad, you would get a P1607CODE.

    I have no codes.

I have a 1996 Acura 3.5 R.L. just put a new fuel pump in and it won't start. It turns over, but will not stay started.


Check your main fuel relay.



Fuel Supply System


PGM-FI Main Relay


Description


This PGM-FI main relay is located behind the dashboard


lower cover. The PGM-FI main relay actually contains


two individual relays. One relay is energized whenever


the ignition is on. It supplies battery voltage to the PCM,


power to the fuel injectors, and power for the second


relay. The second relay is energized for 2 seconds when


the ignition is switched on, and when the engine is running.


It supplies power to the fuel pump.

NOTE: If the engine starts and continues to run, the PGMFI


main relay is OK.


1. Remove the PGM-FI main relay.


2. Attach the battery positive terminal to the No. 3*


terminal and the battery negative terminal to the


No. 2* terminal of the PGM-FI main relay. Then


check for continuity between the No. 5* terminal and


No. 2 terminal of the PGM-FI main relay.


• If there is continuity, go on to step 3.


• If there is no continuity, replace the relay and


retest.

3. Attach the battery positive terminal to the No. 4 terminal


and the battery negative terminal to the No.


7* terminal of the PGM-FI main relay. Then check


that there is continuity between the No. 3 terminal


and No. 1 terminal of the PGM-FI main relay.


• If there is continuity, go on to step 4.


• If there is no continuity, replace the relay and


retest.


4. Attach the battery positive terminal to the No. 1 terminal


and battery negative terminal to the No. 2*


terminal of the PGM-FI main relay. Then check that


there is continuity between the No. 5* terminal and


No. 2 terminal of the PGM-FI main relay.


• If there is continuity, the relay is OK;


If the fuel pump still does not work, go to Harness


Testing on the next page.


• If there is no continuity, replace the relay and


retest.

PGM-FI Main Relay

Print
This relay is located behind the dashboard's lower cover. It consists of two individual relays. One is energized whenever the ignition is ON , thus supplying battery voltage to the Powertrain Control Module (PCM). This relay also supplies voltage to the fuel injectors, and power to the second relay. The second relay is energized for two seconds, when the engine is turned ON , to power the fuel pump.
See Figure 1

Testing
If the engine starts and continues to run, the PGM-FI relay is working and does not need to be replaced.
See Figure 2

Fig. Fig. 2: PGM-FI relay terminal numbers

  1. Remove the relay.
  2. Apply battery voltage to the number three terminal.
  3. Ground the number two terminal.
  4. Check for continuity between terminals five and two.
  5. If continuity is detected, proceed to the step 7.
  6. If there is no continuity, replace the relay.
  7. Connect the number four terminal to the positive side of the battery.
  8. Ground the number two terminal of the relay.
  9. Check for continuity between the number five terminal and the number two terminal of the relay.
  10. If there is continuity, the relay checks out "OK". If the fuel pump still does not work, test the harness.
  11. If there is no continuity, replace the relay and retest.

I need the to know which fuse goes to What in my Honda fit 2008


PGM-FI main relay 1 (FI MAIN) is energized whenever the ignition switch is ON (II) to supply battery voltage to the ECM/PCM, power to the injectors, and power for PGM-FI main relay 2 (FUEL PUMP). PGM-FI main relay 2 (FUEL PUMP) is energized to supply power to the fuel pump for 2 seconds when the ignition switch is turned ON (II), and when the engine is cranking or running.

Car cranks but dose not start, there is no power to distributator or fuel pump


I suspect the at this point, the main relay is defective. This relay controls power to fuel and spark circuits.

The PGM-FI Main Relay is actually comprised of two individual internal relays. When the ignition switch is initially turned ON , the Powertrain Control Module (PCM) supplies ground to the PGM-FI Main Relay. This ground triggers one of the PGM-FI internal relays that sends battery voltage to the fuel pump for two seconds to pressurize the fuel system.
When the engine is running the PCM supplies a continuous ground to the PGM-FI Main Relay. The supplied ground keeps the relay in the "closed" position providing electrical current to the fuel pump, keeping the fuel loop pressurized while the engine runs.
If the engine is not running with the ignition on, the PCM cuts the ground to the PGM-FI Main Relay, causing the relay to "open" and stop the electric current flow to the fuel pump. As mentioned previously, if the engine is not running, the PCM will only supply ground to the PGM-FI Main Relay for two seconds when the ignition switch is initially switched to the ON position.
The PGM-FI Main Relay also supplies electrical power to the Idle Air Control (IAC) Valve and to the fuel injectors.

TESTING


If the engine starts and continues to run, the PGM-FI Main Relay is working and does not need to be replaced.
  1. Locate and remove the relay.

On some models of the Civic and Civic del Sol it is located to the left of the steering column under the dash. Many later models position it either near the passenger right side kick panel under the dash or by the driver left side kick panel up under the dash.
  1. Attach the battery positive terminal to the No. 2 terminal.
  2. And the battery negative terminal to the No. 1 terminal.
  3. Check for continuity between terminal No. 5 and 4.
  4. If there is no continuity, replace the relay and retest

2001 honda civic turns on, then turn off 10 sec,computer say everything ready, no engine light on i had a complete check done with a mechanic,it has spark and fuel pump okay,what could be the problem?


Your civic may be affected by a fuel pump connector safety recall. during the inspection an installation of the fuel tank water may have been left in the fuel pump connector. Over time, this water could corrode the terminals in the connector, causing the engine not to start or stall while driving. Have your local Honda dealer run a VIN Status inquiry on your vehicle to see if it is affected by this recall. If not than monitor fuel pump voltage. Back probe the yel/green wire at the fuel pump connector (acess panel under the rear seat.) if the voltage goes away before it dies than the PGM-FI main relay #2 is faulty. The relay is in the underdash fuse box. -hope this helps lmk

My honda civic 1998 model fuel pump failed and I changed it


The PGM Main relay is outboard of the glove box. You can see it if you get the glove box out of the way, but to remove it, you need to pop the triangular shaped plastic trim off of the end of the passenger side of your dash. The relay is held in place with one 10mm bolt and the electrical connector.
