Run fault codes and check for idle speed sensors/MAF/MAP sensors. If the pump was faulty then it would not supply fuel to the manifold. Test it by having a pressure test done on the fuel. manifold
code p 0106/7 refers to manifold absolute pressure (MAP) and BARO pressure sensor --range /performance and low input problems ===causes wiring ---MAP sensor---Baro sensor --wiring short to ground ---ECM
no 1 not firing would be a problem injector
Hi, see the picture below. Before replacing the MAP sensor, check the vacuum line for leaks. If the vacuum is good and you have a voltmeter, check the signals. With the key on, there should be 5 volts DC between the outer terminals of the connector. Don't take it off--just stick your meter probes in the back of the connector until they touch the bare wires. If you don't have 5 volts there, the problem is not the sensor--it's the wiring or the computer. If you do have 5 volts there, check the voltage from the white wire to either of the other 2. That voltage should be between 1 and 5 volts, and it should change a lot when you start the engine. If it doesn't change at least a couple of volts, the sensor is probably bad. Please let me know if you have questions, and thanks for using FixYa.
Try a toon-up..
Or might be a sensor.. There are several..
Trying to figure these things out is a process of elimination.. Unless looked at by a shop..
check tps sensor (throttle position sensor in backside of the throttle cable) and map sensor (manifold absolute pressure on front little 1 inch sensor with vacuum line) make sure there plugged in. the ecm (engine control module driver side inner fender) and tcm (transmission control module under dash) both need the data to know when to upshift and increase fuel/air. Otherwise the computer runs default values and guesses off of other sensors giving poor performance. also disconnect battery for 15 min. usually resets aveo service lights if you dont have a scanner.
Suggest look under the hood for any wires or connectors you might have bumped loose while repairing the MAP sensor.
Check to see that you are getting a spark to the plugs.
Use care because you are dealing with high voltage and could get zapped.
If still same problem suggest obtain a good Volt/Ohm meter and trace-out your circuits to find the problem.
Shop manual with wiring diagrams is a must have for this.
Sometimes they are available online for free as a PDF file.
Be safe when working with electrical parts.
sounds like it was burning real rich if it melted the o3 sensor harness chances are the converter melted inside and is restrickting the exhaust if you unhook the exhaust at manifold and it runs replace converter and fid out what is making it run rich before you burn out new converter
