codes 327 and 543???

[kurtis adum]

my car pulls this 2 codes when tested. Its a 94 atx 3.2.

Code 327=DPFE output circuit below minimum voltage.

Code 543=Fuel pump secondary circuit failure.


For Code 327, I'd check your EGR valve electrical connections, and possibly remove the EGR valve and clean out the nostrils.

Code 543 usually means the engine has stalled and can be ignored.

it stalls all the time, hopefully because of the egr valve. It stutters to. would that be the problem???
