Will Fuel Pressure Regulator work without FPR control valve?

[jafero]

I am finishing up a KA24E to KA24DE swap. Chassis is 89.
In the process of swap, I disabled EGR and took AIV off.
The KA24DE engine I got didn't come with FPR control solenoid valve, SCV control solenoid valve and it lacked swirl control valve which makes me think this KA24DE is very late model.

It seems like there is a discrepency between KA24E and KA24DE when it comes to FPR and FPR control solenoid valve. While 24E has FPR control solenoid valve, 24DE don't. How did people who did single cam to dual cam swap deal with this?

Will FPR on this KA24DE work right without FPR control solenoid valve?

There is no such thing as a fuel pressure regulator control solenoid valve on the KA. Or any other Nissan engine for that matter.

[jafero]

There is. I remember seeing it on my friend's KA24E FSM's vacuum diagram.

[projectRDM]

No there is not. The FPR is vacuum controlled. There is no solenoid anywhere on the fuel system.

The AIV, EGR, and SCVs are solenoid controlled, nothing else.

[jafero]

I remember seeing FPR connected to pressure regulator control solenoid valve by a vacuum line on the KA24E FSM's vacuum diagram.

[projectRDM]

You remembered wrong. I'm not going to keep telling you if you're too thickheaded to listen.

The DE engine DOES NOT HAVE ANYTHING CONTROLLING FUEL PRESSURE OTHER THAN THE VACUUM OPERATED REGULATOR.

Well my question was when 24E had pressure regulator hooked to control solenoid while 24DE don't, what am I supposed to do with this discrepency. I said 24E FSM HAD FPR HOOKED TO CONTROL SOLENOID VALVE. I DIDN'T SAY 24DE HAD IT LIKE THAT.

R240NA, what every you do, you are annoying and you are not welcomed to chip in your 2 cents in my postings.

[cotbu]

? what ecu are you using? Seems like you want things to go wrong with the swap. And post a picture of the thing your talking about, R240NA was trying to help you!!! You did say KA24E to KA24DE right?!!

Fuck off asshole. I told you twice you didn't know what the flying fuck you were talking about, yet you still kept crying about it.

And sorry I didn't fully understand your shitass typing, maybe if you had a fucking brain and didn't sniff glue all those years your posts would make a little more sense.

lol, ^ i agree with what he posted, i told you in another thread there isnt such thing man...... are you sure your not getting confused with the egr&activated carbon canister control solenoid

if ur still reluctant to believe us, i will copy the page from the fsm and show you

Straight from the AllData which paraphrases the FSM. Also check out pix.

CIRCUIT OPERATION
During hot engine starting the ECU will supply the ground circuit to the fuel pressure regulator control solenoid. The solenoid valve opens the vacuum source to the pressure regulator allowing atmospheric pressure enter the line. This increases the fuel pressure, allowing easier starting.

PRESSURE REGULATOR CONTROL SOLENOID
The pressure regulator control solenoid allows vacuum to be applied to the fuel pressure regulator. The ECU completes the ground circuit allowing battery voltage to operate the solenoid.

PRESSURE REGULATOR
The fuel pressure regulator maintains the fuel pressure at 299.1 kPa (3.05 kg/cm2, 43.4 psi). It utilizes vacuum acting upon a diaphragm to control the amount of fuel pressure allowed to the injectors.

I'm using KA24DE ecu that has one red lamp instead of one red and one green lamp. I'm going from E to DE as you said. =-)

[jafero]

Slip, thanks. Should have done that myself.

Stop acting like R240NA.

I wasn't addressing the post to you specifically. See the post directly above and #3 in my post.

You may also want to know the forum's history before getting into it with members.

History... if you have a piece of history with you, you better not taunt others with that, rather better stay quiet. I don't respect those who show off their so called experience and harass others with that.

Other than that, thanks for your information.

Now study and learn from the diagram that Slip posted. You sure you had 15 years of experience on this?

And go take anger management class.

hmmmm u called it a fpr control solenoid valve

[g6civcx]

Dude, chill out man. I'm just trying to help you out. Why are you getting into it with me? I'm the last person on this forum who you would want to get into it with. Look at all of my posts and you will see. Russ is abrasive but if you can bear with him you can learn a lot.

Look at your other thread:

basically the point that he is making is to know exactly what your talking about before you ask a question. thus meaning that you have searched and its not a question that is stupid/already been asked. some of us like to browse these forums all day and when there are dumbasses who dont take the time to distinguish between a wire and a hose before asking a question that does about something that doesn't exist.

This is my last post with you.

[Vatche]

jafero you really are a moron, your posting on here to get help, people tell you your wrong, and you start arguing with them

someone posts a pic to support what you originally thought was right, but then that gets shot down, and you still dont see it. go to a different board since the 2 people trying to help you spend alot of time helping people and do it for nothing.

better yet im not gonna waste any more time with you. just keep having problems and dont try to learn. i like stupid people to stay stupid.
