This forum is for "fuel systems", which means, ANY COMPONENT THAT THE FUEL COMES IN CONTACT WITH.
This would include injectors, injector rail, fuel pump, fuel relays, filters, gas tank, filling spouts, and the fuel itself or its additives.
This forum is generally NOT for engine management systems, air filters, throttle bodies, sensors, etc., which should go in "Technical Questions" or in the forum for your particular car.

I have had the fuel injection replaced 3 times in the last 3 years.
The last one was only 60 miles ago and needs replacement again.
Could this be a factory defect on the Jimmy or could it be a parts defect???
I am desperate for answers, does anyone know where I can go for some Honest answers?
Thank You

I have a 95 toyota pickup 5 speed 2.4 liter engine. I know my problem but need to know how to fix it. The problem is I have a bad fuel pump that is inside the fuel tank. What I need to know is how do I replace it? Thanks
Install it inline to your fuel line. You need to check to make sure fuel will still pass through the old pump first.
I have done this more than once with great results.
REPLACED ALL FILTERS AND FEED PUMP
ALL LINES BEEN BLEED
FUEL GOING TO INJECTOR PUMP BUT DOES NOT LEAVE PUMP
GOING TO INJECTORS.
I know this sounds obvious but I'm trying to check your work here.
thanks

The foglights, cruise control, and rear brake lights do not work. All fuses have been checked and are okay. The button for the foglights does not stay pushed in and if I hold it in, the lights still do not come on. The parking lights work, but do the brakes work a second bulb? Or is it a two stage bulb? As for the cruise control, I have no idea where to begin. Any suggestions or help would be appreciated!!
Only getting 8.23 volts at the fuel pump power connector. Pump wont run. Voltage at the ASD(automatic shutdown relay) is 12.36v on both sides when key is on.
Where do I look?

MY PROB IS EVERY TIME MY GAS TANK GETS TO A QUARTER TANK OF GAS (LAST BAR BEFORE EMPTY RED LINE) IT SHUTTERS , LOSSES POWER AND BASICALLY DOES THE FUNKY CHICKEN..
MOSTLY WHEN I TRY TO GO ON THE FREEWAY AND ESPECIALLY IF I AM GOING UP HILL
PS I HAVE TRYED MANY GAS TREATMENTS AND THAT HEET STUFF
PLEASE HELP ME

You need to turn off your CAPS LOCK. Most users will not respond to posts with CAPS LOCK because it is too hard to read.

Just keep you tank filled above the last quarter!
Give it a try because I had manuals for every vehicle I drove.
No power detected from OBD to injectors.
Dealer suggested it was the Power control module not the "brain" and
gave us a drawing showing the PCM on the pass side of the engine inside the van
BUT we can't identify it! ANY help? Or other suggestions.

they have a video that just might solve your problem.
I own a 1977 toyota RV yes that's right RV 1977 20 R motor with 78000 mi
and I am starting to have a problem with the electric fuel pump
I am replacing mine with an aftermarket one just before the fuel filter just to give the old one some help

if he is still in high school and they have and auto shop class (should take auto shop I did and it helped me) see if the teacher will allow him to bring in the truck. he just might save you and him some $$$$$$ and get some good grades to boot.

If ok, probably the coolant temperature sensor.
I have Grand Cherokee 96, V8, 5,2. After only several kilometers of driving on the rear side I feel odor of gasoline, without any drops of fuel on the floor of my garage.
Regards Boris Hi,
:confuse:
E85 (a mix of 85% grain alcohol and 15% gasoline) is now spreading like crazy. I recently found out that it is sold just down the street from me. It is cheaper than gasoline (although the mileage is a fraction lower), it has a higher octane level (which makes your car feel like it's had a tune up and an HP kick), it is clean burning and is made from American grown corn. It is a superior fuel to gasoline and as an added plus it is the sure-fire way to get us off of foreign oil. Here are some thoughts on E85:
Check to see if it is available at a pump near you by visiting [url=http://www.e85fuel.com]www.e85fuel.com[/url] .
Check to see if you already have a FlexFuel Vehicle (FFVs - are vehicles built or converted to run on gasoline or E85). Many cars are and owners don't even know it. You can find out by going to the site above. If you have an FFV you have nothing to concern yourself with, just fill 'er up with E85!
Now, I am going to suggest something that flies in the face of all of the widely spread myths out there: After significant research and experience we are of the opinion (although we are still researching some issues which we believe are myths), that ANY multipoint fuel injected car (which has an oxygen sensor in the exhaust) can run on E85 without any conversion! I think most cars made in the late 90s include a multipoint fuel injection system.
I have a 2000 SAAB 95 6cyl and I have been running on half gasoline and half E85 for several months now and have experienced nothing different other than better starting, better kick and cleaner emissions. I am finally convinced, after significant research and the help of my husband who has been building racing engines and running race cars on straight grain alcohol for decades. My next tank will be all E85 and I will be checking back to let you know the outcome.
Do your own research and share your experiences, but here are some of the myths we have encountered:
1. Alcohol is corrosive to the gas tank, hoses, seals and other "soft parts" of a vehicle as well as and pistons. Anything over time is corrosive. Water created the Grand Canyon, but that took a little while to occur. In fact, gasoline is more corrosive and dirtier than ethanol alcohol. That is one reason why modern gasoline usually contains 10% ethanol and detergents, i.e. to keep unleaded gasoline from gumming up things. With E85 all of those detergents are unnecessary.
It is true that Methyl Alcohol (made from wood) is more corrosive and stickier than Ethyl Alcohol. Several years ago, GM did a test study running a fleet of cars of a mixture with Methyl Alcohol and there were problems. Since then the word has been that all alcohol is corrosive and damaging to your car. NOT true. Ethyl Alcohol will clean your engine. Any race car tech will tell you that opening up an engine which ran on all grain alcohol is clean as whistle and looks like a new engine. We are certain that this is a myth and has no basis in fact.
2. Larger fuel injectors are needed because more a car needs more grain alcohol than gasoline to run. We already run E10 in our cars and our cars are built to sense that and compensate for the additional oxygen in alcohol. There is not a significant difference in the amount needed to run E85 which would justify the need for larger injectors.
3. Your pistons will melt. I think this one is just plain silly. The boiling point of alcohol is far lower than gasoline. That is one reason why race car drivers love grain alcohol -- the car runs cooler. That being true, it stands to reason that running your car cooler will actually extend the life of its component parts.
4. The compression ratio must be adjusted for E85. On this one, we are still researching and would love input. We believe that there should be no problems. I have had no problems but we advanced the timing a few degrees just to make sure. If you need an adjustment, your car should let you know, but it shouldn’t hurt anything.
5. We can't grow enough corn to meet the demand. Right now, through farm subsidies we are paying our farmers NOT to grow corn because it is so easy to grow and floods the market. Grain alcohol is made from corn which is not food quality. It uses the entire cob and parts of the stalk and leaves too! It is transported to a local distillery/refinery in a mulch-type form. This keeps the need for long gas pipelines and dangerous gasoline tanker trucks to a minimum. We have sufficient corn growing ability to supply much of the need. We certainly don't need to deplete our soils by growing too much corn, but there are other crops which are equally as effective in making grain alcohol (so we can rotate the crops), but corn is certainly the most plentiful and cheapest to grow. Wouldn't that be a great problem if half the country was using E85 and we started running short of corn? Other farmers could get into the act and share in the profits as well.
6. Alcohol is more volatile than gasoline. This one is just ridiculous. Ask any chemistry student to check into this. Alcohol is far less volatile than gasoline. It is safer to have around us in our gas tanks and in tanker trucks on the road. Hydrogen, on the other hand is extremely volatile, so why the automotive industry is married to the idea that we will one day run our vehicles on hydrogen and fuel cells is beyond me. I don't want a tank of hydrogen in my car!
7. E85 is a "political fuel." I am not sure what that means. I have heard it several times, but isn't a fuel a fuel? Either it works better than gasoline or it doesn't. We believe it most certainly does. If you want to look at the politics surrounding it feel free. Obviously it threatens the oil industry and gives a kick to American corn growers. It also reduces our dependency on foreign oil which prevents our need for war and false friendships with otherwise unfriendly nations. I suppose I would rather give my money to a corn farmer in Iowa than the Saudi Royal Family or other Middle Eastern super rich country. Politics aside – we think E85 is a no-brainer. It is far superior to gasoline and is a renewable fuel.
What are your thoughts? I would love to hear comments and your experiences with E85.
Without the politics and the fat subsidy you would not see E85 at the station. Vehicles that run on E85 get about 25% lower mileage. I think biodiesel is a better way to use our crop land. I am not sure on the volatility issue with ethanol. All reports I have read say it is more dangerous to transport than gasoline. If you have documentation to the contrary feel free to share with us. Lastly the cost to produce ethanol is higher than biodiesel. You cannot run the farm equipment on ethanol. I think it is a political fuel to get more money into the hands of the mega farmers.
