I was in a drivetru the other day and shifted my truck into park. then once I shifted back to drive it just died and wont start back up. I have replaced the battery, multiple relays and fuses, and the fuel filter. The engine is getting fuel and the fuel shutoff switch has not been triggered. Is there anything else I am forgetting? It turns over and starts sometimes but just dies instently.

 

Check the fuel pressure with a gauge, it has to be at least 28 psi to start. Gauges can be borrowed or rented from most parts stores. Use an inductive tester on a plug wire and see if it's getting spark.

I have almost same problem 98 2wheel v6 f150 . direct wired fuel pump have fuel to rail lots of pressure and great spark but no fuel getting to sparks ??? any ideas

 

Ok so it has pressure and they are getting a spark and the truck is starting up but it wont stay on.

 

Does it have ENOUGH pressure? Will it keep running if you give it a little gas? Any OBD2 codes?
