I need to replace the PCM, Fuel regulator on my 2000 accord
In December I had my timing belt replaced,the water pump replaced along with my fuel injector, side motor mount and new battery. Now my car will start but cuts right off. I was told I need to replace the PCM and fuel regulator without doing a diagnostic test. Another $1600 in work. Is there any other solution?

diesel engines high pressure pumps not suppose run dry.diesel fuel keep high pressure pump cool and lubricated.problem could be fuel pressure regulator in the fuel filter water separator housing.replace fuel filter see if it helps problem could be fuel pressure regulator in fuel filter housing, the fuel pressure regulator has a air bleed orifice that allows vent to the fuel tank.make sure fuel pump fuse okay pump getting power. i would let garage or dealership check it out if all fails because your diesel engine fuel timing is pcm controlled if let fuel system go dry you probably have to have fuel injection timing reset or could have damage high pressure pump letting it run dry i hope thats not the case because high pressure pump not cheap part i hope it not that.
COULD BE THE FUEL RAIL PRESSURE SENSOR OR YOU HAVE THE WRONG FUEL PUMP FOR THE VECHICLE.PCM COULD BE OUT OF CALIBRATION.TURN OFF RADIO FIRST THEN DISCONNECT NEGATIVE BATTERY CABLE FOR A MINUTE THEN HOOK BACK UP NEGATIVE BATTERY CABLE.THEN CRANK CAR UP LET IT GET OPERATING TEMP BEFORE THROTTLING IT.GIVE PCM TIME TO RECOGNIZE THE NEW FUEL PUMP.
I have had similar problems and had to replace the fuel pressure regulator. It's a major expense because it sets below the diaphram in the intake manifold. Ask your mechanic about it, it may be the issue. I would get about 30,000 miles between replacement, I've replace it 3 times since purchasing the 2000 chevy blazer new, first one was under warranty.
