Default fuel pump

a car is tech right?
can anyone give me like an auto repair site? I have a 95 nissan 4 cylinder hardbody, and I was told the fuel pump might be fucked up. So we have to remove the bed and get to the gas tank and drain it and replace the pump. The easyest way I have been told besides dropping the tank and doing it that way with jacks and shit.

Try google, you may find a step by step tutorial out there if they used that tank and fuel pump combination in many cars. You might get lucky with a well worded search to find in one of the first few results. <img src=smilies/cwm11.gif>

I do have some advice, you will need goggles for your eyes and any other covering for your face. Remember that the fuel pump needs to have its pressure released before you take it off otherwise a huge PSI's worth of petrol will spray in your face.

I have a couple of questions to ask before you start taking off the gas tank.

1. What does the car do exactly that is a problem?
2. What other things have you done to remedy the situation?
3. I'm assuming you are referring to a Nissan Frontier when you say "bed"? If not what kind of Nissan is it?
4. How many miles are on it?

Unless you run real real dirty petrol and your gas tank is full of gunk the likelihood of your fuel pump going bad in a car that is barely 12 years old doesn't sit well with me. My 1990 Camaro with 238,1xx original miles still has a good fuel pump. I'd have an ASE certified master mechanic with more than 10 years of experience take a look at your vehicle before doing any serious work on it. I just don't want you wasting your time or money. <img src=smilies/thumb.gif>

I have one of these:

I think that is a 4x4, but mine is not.
It all started last week when I noticed I was loosing power as I gave it gas. Put in the clutch when I idle to a stop light and it would die. Now it just got to the point as I was going into work that it dies and doesn't come back on. I have other people helping me and we have replaced the distributer, spark plugs, wires, and the $100 fuel regulator. Now it kinda starts and sometimes idle there if I don't give it gas. Before I buy I new $200 fuel pump I want to drain the gas and put some known clean gas in. But something tells me I will have to spend that money and a step by step tut would be nice, but its seems hard to find info on the web about cars. I just get ads about those books you find in autozone or something.

That sounds like flooding. Have you checked your battery leads. Take them off and clean them and the terminals. Check your electrical ground also. Check your alternator belt and see if it's loose also.

The reason I say this is it sounds like you have to little power reaching your engine itself from the electrical system and so the gas is not combusting like it should and is just flooding your engine instead of burning like it should because of the lack of power.

Mind you this is just a guess and I'd wait for JCE3000GT to give his opinion on this. <img src=smilies/cwm11.gif>

Sounds like maybe your timing is off. Like shawn said sounds like its being flooded with gas. Have the timing checked, run a bottle of fuel system cleaner that isn't cheap generic stuff. Another thing you could check is your intake. Run a can of Sea Foam in the vaccuum line and let it burn any carbon in your intake--if you don't know how to do this ask the most knoledgable person at AutoZone/O'Reilly's/PepBoys how to do it--at least one person there will know. I'd describe it here but without visual referrence it would prove difficult. When using the Sea Foam the more smoke out of your exhaust the more carbon is being burned off, you need give it some good throttle to burn off any excess carbon. Also wouldn't hurt if you replaced your air filter and or installed an aftermarket air intake. Need to make sure your getting enough air for the air->fuel mixture. Buying a Chilton or Haynes repair manual is a good idea and I would highly suggest getting one or both.

Are there any warning lights on in your instrument cluster?

Default Re: fuel pump

you are both right. It is getting flooded. We took off the fuel injectors and gas ran out of the holes a bit. We let it set there and tried it again and bam, flooded again. What I have done so far, distributer, spark plugs, air filter, fuel regulator, fuel pump, new battery. We are going to spray that shit in it tomorrow. Dude knows someone that works at nissan and he is going to ask him too. So tomorrow maybe it will work, I don't know. Spent so far a little over $300. If it is the injectors that would suck because dude says they are like a $150 a piece and I have 4, sooooo... I don't know. Good thing is that everytime we replace a new part it gets a little better.

If it is the injectors that might not suck. If I remember right the injectors not only spray out a certain amount of fuel but also the fuel must spray out in a certain way/direction and if one or more are just partially blocked but in a way that the fuel is spraying in the wrong area for good combustion then just the use of a high quality fuel system cleaner should work and also save a trip to the shop also.

Now that is one fucken long run on sentence. <img src=smilies/magbiggrin.gif>

If there is water dripping out of the exhaust pipe then you've got a cracked block and or a headgasket problem. I hope it isn't either of those things because you're in for a rebuild which isn't cheap.
