Stuck in high water

  • 2014 FORD FUSION
  • 42,000 MILES
Got stuck in a flooded intersection and my car stalled. Had help and pushed it out of the way and checked under the hood and every thing looks dry, belts, air filter etc. Also checked the oil and it seems fine. Was not able to check transmission fluid. Tried to start the car and it will not start. It tries to turn over but wont start. All the lights and everything electrical seems to work. I am afraid that maybe water got sucked up through the exhaust pipe. Please help me!
Do you
have the same problem?

All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can only be tested during the failure. Any other time and they will simply test good because the problem is not present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.

Every engine requires spark, fuel and compression to run. That is what we have to look for.

These are the basics that need to be tested and will give us the info required to isolate a cause.

1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the positive terminal of the coil with the key on.

2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.

3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.

4) If all of these things check good, then you would need to do a complete compression test.

Once you have determined which of these functions has dropped out,
you will know which system is having the problem.
