Yes something is definantly wrong there charlie...


Wasn't getting enough fuel at the end of every gear.... car was Starving itself... With the Throttle full down I could feel her lacking...

What to check now???

I'm baffled???

 

do u have access to a scaner

 

When was the last time you replaced your fuel filter? Another thing to check is a bad TPS sensor, which caused my car to lack acceleration.

Am I the only one who thinks those are excellent times for that Huffy?






TPS is a good possibility, as well as fuel filter. Get a fuel pressure gauge on it, and run it through the gears. Then at least you'll know if it's actually getting fuel or not.

My car had sorta the same thing happeneing a while back. At the top of every gear, it just felt like it was starving for fuel. I replaced my O2 sensors, and it cleared up all the symptoms I was having.

I guess it was keeping my car from going into closed loop mode.

 

I have no scanner... but I see I should probably have one...

I changed my fuel filter out a few months ago.. it's mostly knew...

TPS sensor.... egh? How might I check that out...

any how my car should be mid to low 13's

So I'm wondering if it's a more serious issue.

I did get water on my MAF unit... I have not changed the 02's out and I have 66Kmiles on the dash

I had bad hesitation before and replaced the coil recently... now the hesistation is gone...but hte fuel input is not there. What would add almost 1.4 to a car?

 

Since you have done the filter might check the most simple mistake is it going the right direction?

Since you can't scan the car and see what voltage on the sensor reading, do you know anybody with another car like your and borrow there sensor?

What mods does your car have since you think the time should be mid 13s?

 

ur gona need a lota mods to run a low 13 in a lt1

 

ummmm I dunno man, I run 13.6 with a catback and cai. I plan on doing headers soon and expect low 13's.

 

Everything in the Suspension bin, weight reduction, Headers, pullies, other junk... Billet Fly wheel .. lightend PP .... 4:10's yatta yatta... there's allot of things done. The car is very capable of a low 13 pass.

but this fuel issue is a real problem...


Yeah the Fuel Filter is on right... is there a way to test the sensor with a voltage meter?

 

Put a new 340 fuel pump on it and eliminate that problem.Do it with the "door" method.Cost about 110.00 and 2hours.Go with a 340 and you only have to do it one time for all future mods and it don't cost any more.

 

where might I find this 340 fuel pump? who makes it?

Last time I checked there is no way you can install the Fuel Filter wrong.
One end screws on, and the other is TOTALLY different and has a plastic snap piece.
You would have to be VERY creative to install it the wrong direction.....

 

Is it hard to hookup?

 

It is an intank replacement.You have to swap a couple of wires,the instructions will tell you.Other than that it is like any other pump change.
