p1443 evap code...new 255l/hr fuel pump

[fast97gt]

alrite im all excited that i traded to get the old stang back, but i hav an issue. its the 97 in my sig and its throwing a p1443 evap purge malfunction. the guy parke it for like 2mths because the fuel pump went out, he installed a bigger then stock 255l/hr pump from jegs. i picked it up a couple hours afer he finished, he didnt test drive so the code didnt come on till i got it. he didnt drop the tank for swap, but cut a acces hole that is ever nice from now on out to ever have service it again. but i changed the purge selinoid, and the purge valve. can anyone thank of anything, could it be a faulty gas cap. oh and yes the vacuum lines seem to be in good shape

i have worked on several stangs with evap codes on, even the smallest change sets something off and they wont go back the same in most cases, if it's all stock bite the bullet or look at a jump/cut off wire to turn off manually and if it's built or going to be dyno'd you can turn it off then, as far as the problem nothing to worry about mechanically wise.

That's interesting.....

If all the lines are sealed up then it's most likely the purge valve or the pressure switch. They should be located by the firewall on the passenger side near the AC accumulator.

yes thats rite we cut an acces hole in the trunk 5inchs by 5inchs, cut an aluminum plate 6.5 inchs by 6.5inchs an 1/8th inch thick and used seem sealer for sealing back to the car and probibly 30 self drilling sheet metal screws to button it all up. yes instead of dropping the tank which could take an hour and a half all have to do is take out the screws and take up the plate to service the fuel pump. the hole allows easy access to all the lines and couplings. it did turn out to be the evap purge valve selonoid tho.
