• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Ok guys i finally put my new transmission in and the car ran fine besides a misfire i had the cables wrong, did some wire tucking and moved a couple of things but besides that it runs ok besides the code issue, which is more serious then i thought, Symptoms gas gauge and dic mark full when it is not, it doesn't move from there it left me stranded last week since i ran out of fuel. When i drive it it feels as if the fuel cuts off at times did some research on the code and i came up with a couple of things, the plug/sensor on top of the fuel pump may be dirty or need replacing, a vacuum line but all are new and have been rechecked 4 times, i can drive it but it sputters real bad, as i said feels like it gets cut off. i hope you guys can help i will be checking the voltage to the plug on the FP to see if all is well in a bit, i just want to enjoy this car now that i am done and give it a better tune, IT IS TUNED FOR THE MODS IT HAS PRJ TUNE. Pic of it before the tranny went out, looks slightly different now just a little more cleaner in the bay.

Any help is appreciated guys.

 


Fuel tank pressure circuit low is what the code p0452 stands for. Forgot to Mention that.
 
On that vacuum line stuff. Check that the vacuum line for the canister is connected to the port that is labeled CAN aka canister on the evap purge soleniod. Otherwise..you can cause that issue as well.

Besides that, it sounds like your fuel gauge is bad. Likely you need to change the sender.
 
Thanks for the reply boost, as far as the code goes the only thing I can think of is checking the evap purge solenoid, most likely replace it. The code causes the gauge to do that, my dic at times show the level on start up for 10 seconds then just goes to dashes showing nothing. I've read it is a symptom with that code.

where would that canister be located?
