Replaced pick up coil in '94 300ci.
Hello gents,
My Son and I just replaced pick up coil in his truck, now we can't get the thing running again.
It's a '94 F-150 w/ inline 6.
We put the engine at TDC, and put distributor back in with rotor pointing to #1, but it just keeps backfiring like we have it a couple cogs off, no matter how much we move it left or right.
One thing I noticed was when I put #1 at TDC, the piston is not at the very top of stroke. But it ran like this before changing pu coil.
Any help would be appreciated.
Thanks,
Larry

Only half read it, that is what the timing should be.
Make sure you have the correct firing order for you wires and that #1 is the first past 12oclock position looking at the cap from front of truck.

You have to make sure you're at slightly before TDC on the compression stroke (or you'll be 180 deg out).
Pull #1 plug, turn the motor by hand while someone holds their thumb over the spark plug hole. When you feel pressure building in #1, you will be on the compression stroke. Continue turning it up to about 10 degrees before TDC. Now it should be pointing at #1.
And one of the little bumps on the dist shaft should just be lining up with the pickup on the PIP you just installed (when that little bump lines up is when it fires the coil, sorta like points opening).

The engine cranks clockwise, as you're looking at it. That's the way I've been cranking by hand.
Thanks for the replies,
