You have a short on PCM - powertrain control module , 5volt reference circuit . This will surely make the vehicle not keep running !
These 5-volt reference circuits are independent of each other outside the PCM, but are bussed together inside the PCM. Therefore a circuit condition on one sensor 5-volt reference circuit may affect the other sensor 5-volt reference circuits. The PCM monitors the voltage on the 5-volt reference circuit. If the PCM detects that the voltage is out of tolerance, DTC P0651 sets.
The powertrain control module (PCM) provides 5 volts to the following sensors:
?€¢
The air conditioning (A/C) pressure sensor
?€¢
The fuel tank pressure (FTP) sensor, if equipped
thank you very much now to fix it
The best way is to disconnect the sensors one at a time an see if it will start an run . The a/c pressure sensor is the easiest to get at ! A/C Refrigerant Pressure Sensor
In the air conditioning (A/C) muffler hose assembly close to the condenser , don't know if you know what they are taking about here ! Do you know what A/C hoses look like ,an the condenser ? Condenser is in front of vehicle ! The fuel pressure sensor is on top of the fuel tank !
Here you go look at this youtube videohttps://youtu.be/uyncVz_HAtA
Come on Jeff, neither of these will kill the engine this fast. I could have copied and pasted this info also.
Anonymous, Your cheapest bet is to have it diagnosed. By a reputable shop. Most the good mechanics are bailing from this site. I leaving soon. Jeff gave good info, but seems he is following suit. Copy and paste...
Yes it will a shorted sensor on a 5 volt ref. circuit brings down the whole PCM ! Watch some of scanner danners videos on you tubehttps://youtu.be/uyncVz_HAtA Better yet ground a five volt ref. circuit from TPS sensor an try to start the car !

This code is for the fuel pressure sensor on top of the fuel tank. This usually won't kill the engine. Is your security light stay on after a couple seconds? If the light is on, do a reset. Turn the key on for ten minutes, off for thirty seconds. Try to start. There is also a relearn. three times this, start after the third time. Have a charger on it.
