Resolved 2G Installing fuel pressure solenoid

[GST-1997]

Ive searched and searched and cant find anything as to how to install a a fuel pressure solenoid. If anyone can please tell me it would be awesome I cant afford to have a shop do it.

 

[GRAVEDIGGER]

It's easy... It's attached to the fuel pressure regulator and intake manifold via vacuum hoses and it's plugged in with a connector. Just unplug the connector, unhook the vacuum lines, and then just reconnect everything back to the new solenoid.

 

[GST-1997]

eh? ok . I wish I had some pictures... . Normally anything I put together I dont need instructions, but when it comes to looking at these kinds of things I need atleast pictures to go by .

 

[GRAVEDIGGER]

Here's a picture of a fuel pressure solenoid. Do you have a new one yet? It only takes a few minutes to change one.

 

[GST-1997]

oh alright cool. and no not yet I ordered it on Friday, so it should be getting in this week sometime

 

[GRAVEDIGGER]

Alright, cool! It's pretty easy to change. Just look for the vacuum line coming off the fuel pressure regulator on the end of the fuel rail and follow it to the fuel pressure solenoid. I live 15min from Canton and work in North Canton, so if you have any other problems or questions feel free to PM me and I can lend a hand if need be.

 

[GST-1997]

Oh alright thanks bro Ill let you no if I have any problems thanks alot

 

[GST-1997]

Hey gravedigger I dont have to unhook the battery do I?

Hey gravedigger I dont have to unhook the battery do I?

It is always recommended when working in the engine bay but in this case I would say that it is not necessary. It's just one plug and 2 vacuum lines. It would take you longer to unhook the battery.

 

[GST-1997]

Lol alright, now I was looking at it last night at work and the hoses seem pretty damn tight, anything I should use to get them to come off easier? And same with hooking them back on

 

[Colt4G63 also]

I would think fingers, and maybe a gentle twisting action should suffice.

 

[GST-1997]

Well ill give it a go. Its really cold out so I figured the hoses might be harder to get off then when its warm

 

[Colt4G63 also]

I have heaps of confidence in you. I can't find the cheerleader smiley, so here's this one:

 

[TSiAWD666]

If the lines are too tight and there's slack (there should be) just cut them. While you're there add small zip ties on them to keep them from blowing off the fps.

 

[GST-1997]

Lol I just went and got the fps. $64 for this tiny ass thing wow. Well im going to go put it in now

Ok I got hoses etc off but I cant get the old fps off the mount... :/

Nvm I just un did the mount and knocked it out with a rubber mallet

Well all done now time for the moment of truth

It started. Haha. But whys my cel on still?

 

[GRAVEDIGGER]

It started. Haha. But whys my cel on still?

You might have to clear the code. Just unhook the negative side of the battery and let it sit for a few minutes. Then hook it back up and see what happens. If everything is good it shouldn't throw the code again.

 

[Alky_dsm]

you can also take it to any autozone and they will clear it for free

 

[Empire1208]

stored code. ^^^^autozone^^^= free CEL check and reset....

 

[GST-1997]

Nah I pulled the neg off the battery and it cleared it. I got to wash it today damn was the interior dirty :/

 

[denverguy]

I have the same issue. I was trying to order a Fuel Pressure Solenoid from Mitsubishi dealers but it seems like they don't carry those any more. Could you guys show me where to go get one please? Thank you.

 

[kidmet]

oh alright cool. and no not yet I ordered it on Friday, so it should be getting in this week sometime

Where did you get it at? I am looking for one.

 

[GRAVEDIGGER]

Where did you get it at? I am looking for one.

Looks like it's part number MD113721 and here is one place I found where you can get it.

Mitsubishi Parts - Mitsubishi Parts Center - Call (800) 341-8513 for Genuine Mitsubishi Parts and Accessories

Or.... If you have a pull a part or a place like it around you, you may be able to pull one off a car.

 

[wicked98gsx]

Its called something else at Mitsubishi. I cant remember what they caled it when I ordered mine a few months back but they dont call it A fuel pressure solenoid... I think its call an evap pressure solenoid. Just take the part in to them and show them. They have diagrams for it. Mine even printed a paper with the entire engine bay electrical setup up on it in exploded form. I cant find the paper for it or I'd post the exact name its called

 

[rightsideofthebed]

I have a quick question. My check engine light is on and its for the fuel pressure solenoid. I checked it out and it looks ok but I noticed there's grease on the electrical connector. Is that supposed to be there or is it something that could cause issues? It almost looks like brake caliper pin grease

 

[tatan_Dsm97]

I have the same problem with my 97 Spyder Gst. On day the light came up and when I checked it it showed the P1105 code. However, I did not replace anything and just disconnected the battery to erase the code and see if it came up. Now, it came up again and I replaced the fuel pressure regulator thinking that was the problem because the FPS looks ok. My car seems like misfiring when I am starting to get up to speed and when I start boosting it sputters very bad. Sometimes when I start it, the engine vibrates and seems like one of the cylinders is not firing properly, but as soon as I step a litle on the gas it goes back to normal and evens.

I am replacing the solenoid as soon as I can find one locally or I will order one. Any Ideas where I can get one locally? Autozone, advance and pepboys dont carry them.

Any other things that might be causing the car to act like this?
