well my friend install a walbro fuel pump and i heard the whinning noise from the passenger seat im not sure about stock ones

 

i dont think its the fuel pump cuz if you spray your intake that that stuff it runs and if it is your injectors it would be due to flooding if you wanna find how to unflood it go to rx7.com and theres a 3 step method

 

thanks for the info..im not sure if theres anything wrong with my injectors or not..my fuel pump deffinitly is not making any noise at all so i think i have to change that and take it from there
