well my car was been getting a little hard to start when its cold and running rich so i pulled codes this morning and i found quite a bit out with whats going on ......54 Low voltage at fuel pump OR Low voltage at Fuel pump relay OR Output failure at quad driver module....23 Low temperature at manifold air temperature sensor OR Throttle position sensor error.....32Fault in barometric pressure sensor circuit OR Fault in exhaust gas recirculation valve diagnostic switch OR Fault in electronic vacuum regulator valve..... my question is where do i start?....i gonna put relay and check fuel pressure but then what?

 

anyone?

 

unhook battery for five minutes rehook crank and drive then recheck codes and go from there. those codes were probably set at different times,later jimmy
