not getting enough spark to start the motor

[slow3gt]

my 84 gt isnt getting enough spark to start the motor ive had the coil and ignition module tested and they are both fine has new plugs, wires, battery, starter, starter soleniod, ignition module, so i am clueless of what could be wrong minus there are some wires in bad shape in harness ive taken a wire w/a plug in it and grounded and it is getting spark but it is very little it is getting more spark from the coil wire though but still not alot any help would be appreciated oh and the car is getting fuel also

Make sure the red/green wire at the coil is getting 12 volts when the ignition switch is in the run position.

In addition, ensure your battery has a full charge - when doing diagnostics involving cranking, it's not a bad idea to have a charger ready to go. That's a lesson learned from big bikes (and small bike batteries). The starter turns over but there isnt enough power left to get a decent lookin spark.

And if you happen to have a known, good (spare) coil, it might be worthwhile to toss it on and see what gives.

Good luck.

it was on a charger and still is and i had a spare coil and its still not starting the coil is making decent spark could it be in the distributor?

Have you messed with timing lately?

At this point, I'd take a look at JRichker's 'Cranks but no start checklist' and run through it, rather than jumping around.

Good luck.

yea the timing is very close to set but i really need to have the car started and running to time it perfect ive heard after u put a distributor back in you need to set it to TDC is that correct i thought it was but my dad says as long as it is when you took it out it works just fine

If you restabbed the dizzy very close to your point of reference, that should work fine (in my experience anyhow). You could spin the motor around by hand to check. Or if you have a timing light, you can toss it on there and see where you're at. Jrichker has a nice post for stabbing a dizzy.

Also, if you can slow down a little while you're typing, that would help. Posts lacking punctuation are difficult to read and sometimes thoughts are not clearly conveyed.

Good luck.

well you set the #1 cylinder to TDC on the compression stroke before you stab the dizzy in. The dizzy's on ford engines can go in multiply ways so make sure you have it installed correctly first.
