Question ...car won't start, & I got many questions...


Okay, some history on this car. It's a 84 that sit without a hood & windshield outside for over 3 years until I lucked up on it...
Now, it has a '90 5.0 w/5spd. Their was no ignition wiring (module w/harness to distributor), I got a distributor from the parts store for an 85 with steel gear, along with a ignition box for the same. I got the ignition harness (from ig box to dizzy & coil) from a 83/84 T-Bird at the junkyard.
The motor turns over, there is spark but it really doesn't even seem like it's trying to fire up.
I'm at a loss, I'm pretty good with this kind of stuff, but this has me stumped. There's gotta be something simple that I can't see.... HELP.

I can take pics of anything particular if it will help.

Thanks, Mike

Not really having much history on the car, this may not be too easy. Is your spark good and strong? Verify firing order is correct and that plugs are good. Are you definitely getting fuel? If it sat for 3 years, you should probably drain and refill. Replace fuel filter. Can you hear the fuel ppump run? Have you checked compression? Maybe also check to be sure timing is ok.
Good luck, keep us posted.

Re: ...car won't start, & I got many questions...

Engine in reference is a '90 5.0 w/'85 distributor w/steel gear, and '84 Mustang Durapark wiring, ignition module, etc. All electrical components, dist, cap, rotor, plugs & wires, ignition module, ignition switch, starter, starter solenoid, etc is new.
I can hit the switch, the motor turns over, I get fuel (new pump & carb), I get spark, but no start... arrrggghh. I don't have another vehicle to check with my test light, but here's what is puzzling me: The black wire (goes to dist) coming out of the ignition module has power w/key in ON position, yet wiring diagrams I'm finding for duraspark ignition shows black wire that comes from dist to be a ground? When I plug it up = no more power? Should this wire even have power? If not, what would cause it to have power?

Thanks, Mike

Below is the diagram I am using.

This is the car in reference. I've done lots of work to it, brakes, suspension, motor/trans. The car was painted bright Silver, then rolled out of the shop where it sat for 3yrs. The guy lost interest. I'm real close to finishing it, aside from interior, but I need it running....

Re: ...car won't start, & I got many questions...

The black being hot don't make sense to me either. Generally if you have spark, fuel, compression and timing is correct it should start. The only thing I can suggest is re-check everything. Make sure the firing order is correct.
255,302,and460 show 1-5-4-2-6-3-7-8
and 351 and 400 show 1-3-7-2-6-5-4-8
All with counter clockwise rotation.
Since you replaced the dist. make sure it is correct also. (points to #1,with #1 cyl tdc on compression stroke)
