I am getting the p0452 code and gas is leaking from the evap solenoid could a bad ftps cause this to happen also could the bad evap canister be the reason for the code?

DTC diagnosis depends upon what vehicle you have but it could be the EVAP system or the tank (in most cases) but will require hands-on diag.

Are you getting a P0452 or another code?
Were those four parts replaced because they were diagnosed as failed?

I replaced them because the 2 mechanics that worked on it said that they were causing the code the evap solenoid I replaced because gas was leaking from it I am now taking it to a gmc garage to have them check it out hopfully they will tell me the real cause of the problem

Not sure if this is your problem but I had a Subaru with a persistent P0452 code. One of the things I did to fix it was to replace the gas cap. Long story short, I replaced the gas cap again with an OE cap and that solved the problem. The aftermarket cap didn't do the job.

Got the word back from gmc they said the code was caused by the cat.converter being so plugged up and that the fuel pump was most likely good and didn't need replacing so I'm putting new cat on let you guys know if it works thanks for all your answers

Well nothing changed after putting new cat in still have same problems as before hard starting ,stalling,and when I try to accelerate fast it bogs down anyone have any ideas the gmc mech. Idea about it being cat apparently wasn't right
