I Need help with a 74 Bronco Scout

[DixieDog]

My dad bought a 74 bronco Scout 5 years ago and dropped a rebuilt 302 in it and it ran great.....for a while. he wanted to get it painted, so he sent it to a friends' place, where it sat for five years and rusted.......never got painted. I just recovered the bronco a few weeks ago and now it's at my house. I've already dropped the tank ( rear mounted plastic tank) and flushed it out and reconnected it, put in a new battery, and cleaned it. i'm not gonna lie, it looks rough (I'll try to post some photos). These are the major problems (1) No Power, nothing works including ignition. battery cables look OK, and i can get the motor to turn over, but not start, by bypassing the sylanoid. (2) Everything is rusted; floors, tailgate, doors. I've tried starting it, but it won't fire, even with starting fluid. I'm no mechanic, but I understand how most of the major engine componenets work. Basically I'm looking for some advice on solving these problems. Usually I wouldn't take on this battle, but with an almost new motor in it, I have to try.
Thanks,
DixieDog

You probably don't have power getting to the coil. Go here.

This will be a great help, scroll down to the yellow table and click on your trucks year. If you can, print all pages out and study them. You will understand what each part does and why it does it.

If it sat that long, the diaphram on the fuel pump is probably shot. Fuel pumps are cheap so I'd replace it. Also check the electrical side as mentioned.

Well, for starters you could pull a plug wire off and ground it out using a screwdriver and look for sparks while turning it over. Make sure you aren't touching the metal part of the screwdriver while doing it or you'll get a nice surprise(if it's working).

You will likely have to go in and scuff all of the electrical contacts under the hood to remove the 5 years worth of rust(however minor it may look to you), especially the battery and solenoid associated wiring.

To start, you might want to give the engine electrical a good look over. Check all the plug's and wires, fuel lines and so on. You should have at least got a rumble using starting fluid. Seems to me you are not getting any spark. Have you pulled any of the plugs out to see their condition?

Thanks for the help. i'm going to check out the entire electrical system tommorow, and hopefully buy a new fuel pump. Can I buy a pump for this bronco at an auto parts store?

O'Reily's does also.. So basically any parts store should have one in stock.
