Engine Performance problem
2002 Ford Focus 4 cyl Two Wheel Drive Manual 120000 miles
Car has spark and fuel, you can hear the fuel pump come on. One time out of ten the car will crank and run, but die immediately. The rest of the time in will only turn over. Have tried spraying the better gas into the throttle body will run a little longer but still dies. Have removed the fuel injectors and they look awful. Is there anyway to clean or rebuild the fuel injectors?
Check the fuel pressure to rule out the fuel pump and comeback with the readings if okay listen to the injectors if its clicking and then report back with some results-

Don't have anything to measure fuel pressure at this time, but pretty sure I have it. The fuel injectors are clicking. Have removed them and hooked up battery to them with clicking. Have blown air through them with air compressor.

Sir- you need to check the actual pressure with a gauge the eyeball and thumb method is not gonna work. EFI system don't like low fuel pressure.
