2001 ford focus SE wont start.
2001 ford focus SE 2.0L SOHC wont start. It cranks
but wont run. Check engine light reads p0193 fuel
rail pressure sensor a circuit high input and p1131
lack of heated oxygen sensor (bank 1 sensor 1)
switch indicates lean. Car has half a tank of gas.
New spark plugs and wires. Already replaced
ignition coil pack, fuel rail pressure sensor and 15
amp fuse the other relay fuse clicks so i know it
works. heard noise from fuel gas tank for about 2
seconds so i guess fuel pump works. There is no
schrader valve on this car. When i took the fuel rail
pressure sensor off the fuel rail no gas came
gushing out so idk if that means the fuel pressure
is low? Car sucks a lot of coolant out the reservoir
when attempting to start, No leaks. Spark plugs
keep getting gas on them, not sure why? Car has
small squeaks when starting coming from engine.
Sounds like small misfires. Please help been trying
to figure out for almost a week.
you could spray something flammable into the throttle body and see if it runs for a bit, like ether, brake clean, gas, just be careful. Yeah even the factory manual states that you should add a mechanical gauge inline with the fuel line under the hood to check pressure. It's not really needed with this vehicle. There is no return line, and no constant pressure. The PCM controls the fuel pump speed depending on what the fuel sensor tells it.
So if i spray brake cleaner into the throttle body then it means the fuel pump is working or weak? How would the spark plugs be getting gas on them if the fuel pump wasnt transporting the gas up to the engine?
If it's not working, you just eliminated the pump or fuel issue. Now you have to check for spark, if spark is present, do a compression test, you may have a timing issue.
I sprayed brake cleaner down the throttle body and still no start. I also used a spark plug tester on all four cylinders all of them had a blinking light.
Now u need to do a compression test to see if u may have a bad timing belt or blown head gasjet
the coolant issue might indicate a bad head gasket. or cracks in block or head.
My car does the same. But when starts rpm goes high and die.it showes low imput at fuel rail sensor
