have a 95 f150 4.9 300 have no spark coming out of the distributor ihave replaced the ignition module,pickup coil,coil,wires,cap,roter,crank sensor relays all the fuses in power distribution box are good any suggestions this things driving me nuts.

 

Crank sensor?

When you say "pickup coil" are you referring to the PIP inside the distributor?

 

yea replaced it got it at autozone

 

Do you have power going to the coil? Is the distributor turning when the engine cranks.

 

yea distributer is turning have power to the coil i have power going in but no power coming out for some reason and i have replaced everything

 

No power on coil negative would be an open coil, or do you mean no spark by "no power out"?

 

no power coming out of distributor have power going in but not out

 

We were talking coils... what do you mean?

 

i have spark from the coil to the distribitor i have no spark coming out of the distributor i have replaced the pickup coil inside the distributor coils new ingition modules new also put a new crank sensor plug wires cap roter button relays just gettin no spark out of the distribitor cap and dont know why

 

So you have spark coming out of the coil wire, but not out of the spark plug wires, right? That is either a weak spark that can't overcome the resistance of the ignition system (weak coil) or too much resistance in the rotor, wires, or cap. I've seen bad rotors before and the low end wires that the discount stores sell cause missfires and no starts. If you hold the coil wire close to ground, does it throw a nice blue spark? Slowly moving it away from ground, it should throw it 1/2" or more.

 

Just saw that... I use their parts a lot until it comes to ignition components. NAPA is worth the extra $$.

 

yes getting a nice blue spark out of coil wire just nothing coming out of the distribtor through the plug wires have power going to the crank sensor pickup coil and ignition module checked those with a test light

 

You dont have a crank sensor, I guess you mean pip, what ford callls the pickup coil in the dist.... as far as module and other primary ignition, there's no need to check that if your coil is making spark. Sounds like you got a defective cap or rotor. I guess it could be moisture inside the cap also, nothing got rained on did it?

 

nothing got rained on ill get a new cap and roter and try that
