Is this my fuel filter?

[jrider]

Every once in a while when I turn off my engine after driving, and go to start it back up shortly after, it will not start. I will have to wait a good 10 or 15 minutes before the car will start. Even after that, I will have to give it a good amount of gas after it starts, or it tries to stall. It doesn't seem to be a problem if I let the car sit for while after driving. It only seems to happen when I stop the engine for a short period of time (around 10 minutes). Sounds like a fuel filter to me. Possibly fuel pressure? But I would think pressure would cause problems when driving, which is something I never experience.

Sounds more like a faulty fuel pressure solenoid which raises fuel pressure when engine is started while it is warm so that it won't vaporize.

That woudn't be the pump?

Alright, I'm gonna take your word for it on this one. I do want to replace my fuel filter as well (hasn't ever been changed). I do have a couple questions though. First, when I went to pick up a fuel filter at AutoZone, I saw two different ones listed for my car. There were listed as "with vapor return"or "without vapor return". I had no idea what to get. I asked the person there, and he was clueless too. So which do I need? Secondly, where can I find this fuel pressure solenoid, and how much is that part going to be? Thanks a lot!

 

[bane3d]

I'm assuming the one "with vapor return" refers to the hose that leads back to your charcoal canister. The other one doesn't have this but don't quote me on this, this should be something that you verify by looking at your car and verifying yourself. I really recommend a Chilton's guide and consult that website that I showed you. It should answer most of your questions and should tell you what kind you need.

Junkyard. Free if you can fit it in your pocket.

Your problem sounds like a case of vapor lock-- somewhere your fuel line may be getting hot enough to evaporate standing fuel in it. After a while, the fuel cools back down and recondenses-- that's why it starts fine after the car cools off for a while. The Fuel Pressure Solenoid (FPS) is supposed to help prevent that, so maybe yours did go bad. I've been driving without mine for years now, however, and have never had a problem.

One thing you may want to do is trace the fuel supply line from the tank up to the engine and see if maybe it's getting too close to an exhaust pipe or something-- whatever might cause the fuel in the line to evaporate when sitting. Also check the vacuum lines going to and from the FPS.

i don't think its your FPS. I have mine bypassed sois conne the FPR cted directly to the manifold. I thought I heard the FPS is for cold starts it would raise fuel pressure to start a cold engine. My suggestion is to make sure you replace that filter, and go get your pump checked because i think your pump just is the problem

 

[doug]

No, the FPS is for warm starts. And if it were the pump, why wouldn't it act that way all the time? It may not be the FPS, but it's possible, and it's more likely that than the pump or the filter.

Okay guys. I think I might have a fuel pump going on me, or a clogged fuel filter, or combination of both. My girlfriend drove my car to work the other day, after driving only a few miles to get lunch, the car would not start back up. She had to wait nearly 45 minutes (which is more than I've ever had to wait) before it would fire back up. So I've been driving my car around trying to see if I could reproduce this problem. I've noticed a little sputtering when stepping on the gas. Not all the time, it seems to only happen when I first start driving the car. After the car warms up, it seems to be fine. So my question is, could this be a clogged fuel filter, or would a filter not affect driving? I guess I'm really hoping it's only the filter, I really don't want to have to spot the money for a new pump. Thanks guys.

yeah.... its your fuel pressure solenoid...

I had a check engine light because mine was malfunctioning...since it was just emissions, i neglected it, i was to busy working and getting parts for other Dsm's to change a part on my own. ..i ignored it and it began to fail after a week ...and the same thing would happen to me as to you...after driving it for a while and shutting it off it wouldn't start back up...(fuel would vaporize). then i just picked up a stock FPS at work swapped it in...and no more problems. i did allot of my other fuel maintenance at the same time so I'm not completely positive....

also i might suggest taking it off and cleaning it with an air compressor...it could be jammed with carbon and what not thats making it go bad.

i

update us.!

but it could be a combination of things..possibly your fuel filter...pump, and solenoid...

To the junk yard! I'm gonna go tomorrow morning. The only problem is the place doesn't have many Eclipse/Talons (2G or 1G). When I say many, I think they might (might) have one. Would this part also be on an Avenger/Sebring?

possibly...try finding an engine diagram...or some one familiar with those cars to tell you where its located (if equipped)

PS: i edited my post above a bit...i forgot to mention that when i changed my solenoid i did my fuel filter, fuel pump, and used allot of gas treatment also, dry gas, injector cleaner, complete fuel system cleaner, all on a full tank...and the issue went away.

i would suggest the same for you...if you have the money to do so. since winter is comming and our car hate winter...well if its cold.

a good place to start to solving this is change the solenoid, if the issue remains continue to narrow down possibilities...(fuel filter, fuel pump)

 

[jrider]

Thanks for the help man. I'm gonna see what I can find tomorrow at the junk yard. I'll keep ya posted. Thanks again.

Hey, just wanted to give an update. I went to the junk yard, and I couldn't find that solenoid. I think I'm just gonna do the whole thing. Pump, filter, and solenoid. I looked at AutoZone and they had a fuel pump for $167, and the strainer for $15. I looked into a filter, but as I asked before, it says with vapor return line, or without vapor return line. I'm not sure which one I need to get. I'm going to have the guy do this for me that I normally have work on my car, but I'm gonna get all the parts. Also, if I call a dealership to get that solenoid, would I just ask for the fuel pressure solenoid? And is there anything else I'm going to need when replacing the fuel pump? Gaskets, etc?

 

[danny_l_2005]

I would never buy a regular fuel pump for $167. If i had that money for a fuel pump; i would buy a walbro 190LPH for $100 since they say it won't overrun your stock FPR as a Walbro 255 would. I would buy the fuel filter first install that then if the problem still continues check or buy a fuel pump.I honostly don't believe its your FPS because as you said as your car was on; you notice a lil sputtering when you gave it gas. Also check if you FPR is good by switching it with a friend of yours who has also a 2g dsm.

 

[Drift_SM]

thats a good point ^ the FPR (fuel pressure regulator) If there is a dealer near you i would go and see if you can find a tech to help solve the problem, and also pic up the parts you need. replacing your fuel pump and filter should be a must do no matter what because its Maintenance and will help your car in the long run. as for the solenoid and FPR...i would order the solenoid and replace the old one...but if the problem still occurs then order the FPR. If i recall...those parts are some what inexpensive. don't quote me. best of luck.

having the same problem run into walmart then cant start when i come back out
