P0452/P0442 Evap Codes

[jalopyjoe]

I'm not as seasoned as some you guys, but I've replaced my pump about 4 times. Had the 0440 code go on and off. So I hope I can help a little with my little experience.

After my original pump went out, I replaced it with the aftermarket one. Then reading the forums, I found out that you should get either bosch or delphi because the other ones pump out only 55psi while bosch & delphi does at least 60. I read somewhere here that at 55, it causes hard start, rough idle, and also ses to come on. I definitely had hard starts, until I let it prime a couple seconds to build pressure then start. Each cheap aftermarket pump dies out in about a year. I think I read autozone pumps for the S's are junk because it last about a year only. I finally replaced my pump with an ac/delco (delphi) and got a new fuel cap which should take care of the 0440 problem, from what I read. But yours is 0442 which, from what these forum says, is a larger leak if I'm not mistaken, so I not sure there. But the pump, I think you should get delphi or bosch. Me, I stuck with delphi since that's what is used by the manufacturer.

When you said you had to cut & replace your harness, I found that strange since I never had to do that even with the aftermarket pumps I got.

Hope this helps.
