Having to get the car towed home, no resolution was available. At first I thought the battery had gone bad, but doubling up on jumper cables did not start it. The voltage at the posts I found later was 12.8 volts (normal). The battery in general works properly, with turning the starter motor over and over on one charge it has not lost its power.
This led me to think the fuel pump or fuel rail was not working. I replaced the relay and pump because the original pump made no noises with the ignition in the "on" position. I found voltage between the battery and the pump on a few different leads being a 12.4 volts, a 5.5 volts and a 5 volts. There are two harness there. I tried to start the car after replacing the pump and it did not start.
Since my approach was not accurate I dug into the ECU trouble codes. My OBDII reader gave me
P0310.
P1700.
P0710 pending.
P1B00 pending.
My check engine (MIL) light is off.
One monitor was not ready or was able to finish its diagnostics check. I am handling Christmas at the moment so I cannot check to be sure which one right now. [Fuel Monitor]
I have read into these codes and thought I would give someone else's fix a try. So, I replaced the water temperature sensor and this did not change anything.
P.S.
New spark plugs were installed a week before this. Each plug is torqued to 15 ft. Lbs. Distributor end and plug end on all four cylinders all visibly produce spark.
I have exhausted all knowledge in this brain of mine!
Could there be another component I am missing in the fuel system? A reason the fuel pump is supplied with power but does not turn on? Evap system maybe? It is a brand new fuel pump. Any known sensors that could cause this behavior?
Any information or ideas in response to this would be greatly appreciated!
Thanks,
Jesse
Also, after replacing the fuel pump you cannot hear the fuel pump run/power on.
