Honda Accord will not start

VEHICLE: 
2002 Honda Accord EX 3.0L, V6, MFI, SOHC, Eng Desg J30A1

MILEAGE: 
135,583

Problem
Intermittent no start. When the engine does not start, there is spark but no fuel pressure.

Tests, diagnostics 
1. Locate the Programmable Fuel Injection (PGM-FI) main relay, under the driver's side of the dash, by the brake pedal. The Black/Yellow (BLK/YEL) wire powers the fuel pump.

2. When the key is turned on, the Engine Control Module (ECM) will ground the Green/Yellow (GRN/YEL) wire for 2 seconds so the fuel pump will operate.

3. If there is no or low voltage on the BLK/YEL wire, then verify that the Red/White (RED/WHT) wire has good battery voltage. If the circuits are OK, then the common failure is the PGM-FI main relay.


Potential Causes:

PGM-FI Main Relay

Ignition Switch

Confirmed Fix:

Replaced Programmed Fuel Injection (PGM-FI) Main Relay

So there is a conformed fix on a honda accord no start
