Got done work...truck keeps cranking and no start. Battery seems to have plenty of juice...cranks fine...but wont turn over.

Im assuming fuel related. Fuel filter was replaced 4 months ago. Dont think it could be that. Would it be possible to find out if it is pump


Could it be something else? Spark plugs have maybe 30k on them

 

Test anything? Spark? Fuel pressure.....the usual stuff you do when an engine wont start??

 

Nah just happened a few hours ago and just got home...was curious on what to test. Just spark and fuel pressure?

 

I tried starting it using starter fluid. Got nothing. Buddy told me to check crank sensor...when I wiggle it...itll start...then died 3 to 6 sec later. Can all this be from a bad sensor and or short in wires to this sensor?

 

You sure its not your ignition switch?
There's three phases in your switch. One could be bad and still let it turn over and act like its not electrical.
Just happen to mine.

 

it is the fuel pump, naturally with a full tank of gas lol. my friend was banging on my tank while i tried cranking it, and she started right up and ran fine for 15 minutes until i shut it off. which is how we ruled out any electrical and grounding issues. the worst part is i literally just filled it up...couldnt be easy enough to be at half (which i never run it past)

 

A in tank pump never goes out with a empty tank - murpheys laws - actually I think the weak pump is, lets say hot then the cool fuel goes in and hits it and finishes it off

 

Haha you got that right!
