Hi everyone Im new here and in desperate need of some help.
The car Im trying to fix is a 93 mercury sable with a 3.8 and automatic transmission.
It all started about a month ago. while driving the car at normal speed it would surge and act like it was going to stall. As time went by the problem got worse.
I started by changing the fuel filter and checking for trouble codes. The only code returned was one that said the car wasnt in park?
Needless to say this didnt fix it. Next the car died while driving and wouldnt restart. I had the car towed to my house and here is where im at=
when the key is turned on there is a realy loud buzzing coming from the (BCC I think its called its located in the front on top of radiator). The car cranks over fine but wont start.
I figured the BCC was bad because the loud buzzing was never ther before so I replaced it.
No luck with the new BCC it still has the loud buzz and wont start, but if I disconect the fuel pump at the inertia switch in the trunk the buzzing goes away.
So I replaced the fuel pump thinking it must be shorting the BCC again no luck, buzzing still there car wont start.
So I have pressure at the fuel rail and I have spark at the plugs but the BCC wont stop buzzing and the car wont start.
So why is the BCC buzzing and could it be the injectors arent firing?
Thanks in advance and I realy appreciate any help you guys can give me.
