my problem is that i can fill it up it gets amazing mileage untill it comes to about a half a tank and its like i drive from work (3 miles away) to my house and im on E WTF?!?!?!?!?! it pisses me off so bad because i bought the car for mileage and now its doing horrible and can anybody tell me what kind of trim model it is its a 91 crx with a/c non power steering manual with leather seats and crank windows? wtf it confuses me lol im lost with this car somebody help me please i know nothing about crx's of efs i have allways had eg's so im lost please help

 

sounds like you need a complete tune up...!!!

 

If it was originally a 5speed it should have a 3 in the 1st part of your VIN. If you have a 6 after the 3 in your VIN and it has factory sunroof you have an SI. If you don't have a factory sunroof it's an HF.

CRX's also didn't come with power windows or steering. Leather seats were probably put it in later by the owner

 

i have done a tune up all except an air filter thats all im lacking and nope i dont have a sunroof and no the number part of the vin is 8356 from what the vin is tellin me is its an ed8 and its dual point bullshit on the car so whats the stock mileage for a dual point d15b7?

 

Is it possible that you still have all the gas in your tank but the fuel sensor is messed up thus giving you an empty reading only after 3 miles?

 

if the float sending unti on the pump it self is bad but its a new fuel pump thats only 3 months old and mabye if the gauge if messed up idk

 

Air filter helps toooooooo

 

this would be a good time to install an integra sending unit. these are able to let you know when you are actually running low. your gauge might also be bad, mine used to jump all the way up after filling and go down 1/2 way then stay there, till i filled up.

 

wait... you have a d15b7? that's not stock... that's from an eg. can you post up your vin? i'm curious about your car... lol not in a bad way tho

 

Sounds like your gauge or float is bad.

 

It's a bad gauge or float. Actual fuel economy has absolutely nothing to do with the level in the tank unless there is a leak fro the tank, then the higher the level the faster the leak.

 

soooo your losing/using fuel fast after a half tank? wt ef?

 

He does not actually say he loses fuel fast what he says is the gauge shows half to empty fast. He has inferred that means losing fuel fast, but he provides no data to support that inference.

 

umm no im not looseing it in anyways shape of form (i.E. leaks or hole in tank) i can fill my tank up to a half of tank and i can drive home from work which is 3 miles away from my home and i will be at a quater tank when i get home and its a 91 crx dx i beleve and if you guys want i will post up a vin and its a d15b2 dual point injection with an intake and exhaust and thats it

 

The fuel level gauge in these cars is not linear, nor is it linear in any other Honda that I've ever owned. You will always see the level drop more quickly as it gets lower. Of course it is possible that your fuel sending unit or float is defective, but unlikely. They all do it.

Keep in mind that parking on an incline will also affect the level of fuel displayed on the gauge.

The gauge and tank have absolutely nothing to do with the car's fuel economy. Average fuel mileage is calculated by dividing miles driven by gallons burned, thus you should be estimating your mileage by checking the trip odometer and the volume of fuel indicated on the pump when filling up.

 

i have a 91 crx dx too with a stock d15b2 dual point also and im having problems with mine also it will stay on and drive but once i press the brakes the car shuts off....any clues?

 

Test alternator output and battery.

 

best bet is to change your gas tank thst what i did and it worked they are only 50 bucks at your local kunk yard or a lil bit more but i got mine for 50 and my car does not act up anymore

 

after it reads e if you put gas in it how much does it hold? should hold 10 gallons if its empty.. thats a easy way to tell your mpg.. fill it up and drive it till e, at e you should have went 300 miles. that would be 30mpg witch is what you should be getting at least
