Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello and thanks for using Just Answer.I will try my best to help you with your question.
You will need to check and see if you have no fuel or no spark.
To test for fuel, on the metal fuel lines for the fuel injectors there is a test port called a schrader valve. It looks like a tire valve stem. push the needle down and see if you get a big spray of fuel.
As for spark, remove one spark plug and coil and plug the coil back in and put the spark plug into the coil and stand it upside down. Crank the engine over and see if you get a bright blue/white spark.
Let me know what one is missing, fuel or spark.
I am not a mechanic...please tell me where to look for the schrader valve..the owner manual does not reference it..also a little more description about checking the battery cable woulde be helpful.
No problem. We can take our time. I'll explain things better.
The schrader valve is located on the passenger side of the engine on the intake manifold. It is near the back side of the fuel rails near the fire wall under the coolant hoses.
If the engine cranks over, the battery cables are ok. just make sure they are clean with no corrosion.
FOUND THE VALVE HIDDEN UNDER A HOSE. DID GET A SPRAY OF GAS. NEXT?
If you have a spare spark plug, instead of removing the one in the engine, take a spare spark plug and put it into the plug wire and crank the engine over. You should get a bright blue spark at the plug.
we know you have fuel pressure, now we are checking for spark. The engine needs fuel and spark or it will just spin over like your engine is.
the Orange caps are the fuel injectors.
Your engine has coil overs. There are coils on top of the spark plugs. The coils are black and round at the top.
They are held down by one 7mm bolt.
When you turn the key to on, the check engine light should come on.
When you crank the engine over (try to start the truck) the check engine light should go off.
See if it does this.
The check engine light is on the instrument cluster.
