i have a 97 f150 4.6l v8. truck stopped running. cranks but does not start. so far I have installed new starter, new crank sensor, new primary battery fuse. for some reason there is no current to the coils. any advise?

 

Just wondering why you would install a new starter when you say it cranked...what about an Ignition relay ?

 

Check all of your fuses under the hood and below the dash.

 

when i installed the starter it was not cranking.

 

i checked all the fuses. maybe ignition coils?

 

Not all at once. So the timeline to be clear is,

Truck stopped and wouldn't crank

You installed starter and now it cranks but wont fire?

 

correct

 

Okay, that tells me its a cut off. Check these things

In the passenger plastic kick panel, there is a black box with a red button on top. This is the inertia switch, make sure it is depressed all the way.

If that's good. Start checking every one of your fuses. I would start with the maxi fuses under the hood and work my way inside.

Let us know if this works.

 

i have checked all of those things and they are good.

 

Okay,

How did you test for current at the coils?
