jumped timing - 1988 Ford 302 - HELP PLEASE |
|
|
story: Ford pickup suddenly stopped running, though several months before I had
replaced a leaking timing chain cover, new water pump etc. - I noticed the
chain was very loose, but I was ignorant and did not replace. Anyway, after
getting the pickup home I could not get any fire to the plugs, and thought
about the chain. Did the chain jump?
Slowly but surely I replaced just about everything - new distributor, plugs,
wires, cap, rotor, coil, module, and finally the chain and sprokets. When put
back together it starts but dies when put in gear and barely idles, but
occasionally will run perfectly.
When the harmonic bearing mark shows TDC for number 1 piston, the rotor points
to number 4 piston on the dist. cap. When I replaced the timing chain and
gears I aligned them with marks pointing to each other, though the rotor again
was not pointing to number 1 on the cap. Help!!!
thanks for any input

The cylinders are numbered as such;
Front
Dist.
5 1
6 2
7 3
8 4
The firing order is 15436872
The rotor turns counter clockwise.
I suggest before you go ripping a whole bunch of stuff apart and
wasting more money, that you verify that the spark plug wires are
routed to the correct cylinders in the proper sequence, and that
you are verifying #1 TDC correctly. |

Seems to me that Ford doesn't align the marks. The y set the marks
sideways and count links between them. The chain usually has colored
links to assist. Not being a Ford fan, I don't know the count but you
may want find a manual (even a Haynes) to get it right.

After verifying the wires are in correct order, align the marks, ensure |
#1 has risen and produced compression(put finger over #1 sp. plug hole & you
can definitely feel the pressure as you bump the starter). Then "walk" the
wires around in the dist. cap until #1 is aligned with the rotor. Try
starting it. Good luck, s |
