My 2001 F150 Harley truck is cranking but not starting, has original fuel pump. Had a no start situation followed by a start and drove home, 4 miles. Now still cranks but won’t start. I am thinking just to change fuel pump. Has 77K miles on truck.
I will see if any codes are present next. Thoughts?
Thank you and Happy New Year!

 

Can you hear the fuel pump prime when you turn the key on? Check for fuel pressure, check for spark.

 

That is good info, as I have heard my pump priming for 20 years, will check and advise. Appreciate ya!!

 

"Codes" are unlikely to provide information more useful than observations and some analysis.

Additional observations needed to help focus:

What is the state of the odometer and the THEFT light when the key is turned from OFF to RUN.
What is the state of the check engine light when the key is turned from OFF to RUN and then when the key is turned to START and the engine cranks? Does the tach also register or not?

 

well, no priming noise from the pump this morning. Could the relay allow the pump to fail as well?

 

Well there is no priming action to hear from the pump this morning, could the relay disable the pump as well?
thanks in advance!

 

There are a number of things that could cause that symptom.

You need to answer all the questions.
