I don't think you can blow over 30psi of pressure.
Most people can't blow over 10psi...

Hmm... I'm telling him that the pulsation damper doesn't require fuel pressure to pass. Am I wrong? (Oh..oh). Or are you referring to the FPR?

HAILERS

You can't blow thru a fuel pressure regulator. Unless your a blowhard.

This: ********For some reason, when I put the ignition on, the pump does not prime, but once I turn the key, it starts working.***************

Your not reading what is being written to you. WAKE UP. The fuel pump DOES NOT run just because you put the key to ON. There is no goddamn thing as prime.

The pump runs if the fuel pump check connector is jumpered and the key is to ON. Or anytime you hold the key to START. That's as close to PRIME as you'll ever get.

Read the FSM if you don't know what a fuel pump check connector is. It's free and online. FUEL section.

according to that pic, I did blow threw the fpr, but not the pulsation damper.

HAILERS

The FPR should be the one with the vacuum line connection on it.

Some models, Japenese versions I think, have the FPR on the little (Primary) rail instead of the secondary rail as shown in the picture. The FPR is always the last thing in the system before the fuel goes back to the tank.

You shouldn't be able to blow thru the FPR with your lungs only. Like they said above, it should take approx 30psi to overcome the spring pressure in the FPR to allow the thing to open.

The fuel pump check connector is near the right front strut tower. It's more or less shown in the picture. It's yellow in color,. Two sockets in the plug.

That is a series four fuel schematic.

I think I may have misinformed you about the pressure damper. I have two extras, and just tried blowing through them as you said you did. One, I could blow through easily; the other I couldn't blow through. I stuck a punch in the one I could NOT blow through and felt spring resistance, which I could not feel in the other. Based on that, I believe the one that I could not blow through was working correctly, and therefore, yours probably is as well.

I thought the PD worked as a shock absorber that worked at the end of the system to absorb pulses. Apparently, the fuel has to actually move the damper before it can flow through.

Sorry if I added to your quandry.

I was told that my engine was a J-Spec engine. I didn't believe it was because it had the egr system on it.

These are pics of my set up. I circled the piece I pulled out and the piece in question. I get fuel flow up to that piece.

That's the fuel pressure regulator in the picture on the left. It appears to be mounted on the primary rail in the second picture. That's your pulsation damper on the secondary rail. That set-up is not at all like mine.

On the American-spec, fuel flows in the threaded end, and out the fitting on the side. Are your fuel lines plumbed so that fuel flows in that direction? It won't flow through it backwards.

Edit: Re-read what Hailers said a couple of posts earlier. Your line from the fuel filter should run to the pulsation damper on the SECONDARY rail. Your return line should be hooked up to the FPR. If you don't get flow with that configuration, maybe your fuel pump pressure is too low.

Yeah, I didn't look at the picture enough. The return line should be going to the lower rail where the FPR is and the pressure should be going in the upper rail where the pulsation damper is. The jpg I attached earlier is of a USA configuration with the flow just the opposite of what the car in the picture is (JSPEC engine, I suppose).
