Engine Mechanical problem
1996 Ford Contour 4 cyl Front Wheel Drive Automatic
A week ago one of the short heater hoses under the ingition pack burst. I had to remove the thermostat casing to get to it, repaired it and the engine started fine. As a side note, the connectors to both the coolant temperature sensor and the temperature sending unit. I had to solder wire onto the terminals and then tested them both. Normal readings were found. Left it overnight and the car refused to start the next morning. I have done everything I can think of to get it to start, but have hit a wall.
Checked the timing and timing belt.
Tested and replaced wireset
Removed the first O2 sensor to make sure that it wasn't back-pressure from the exhaust
When checking the spark plugs I noticed that the cylinders had gas pooling.
Pulled the throttle body and found fuel pooling in the bottom of the Intake manifold
Dried up the pools of gas and tried restarting
Checked the fuel system, pressure OK, pressure regulator holds vacuum pressure (diaphram intact)
Pulled injectors in case they were sticking open. Soaked them in cleaner. Poured cleaner in the top of the injector and used 12v source to activate valve. Cleaner drained through.
Tried to start again and you can smell the fuel. Still flooding.
I can't think of what else to try.
