the only way i could crank the motor is by cross jumping at the starter relay but i dont have spark when doing this. yesterday i searched for the fusible link and could not locate it can anybody tell me where it should be located.

Ok I finally found my electrical problem it is the red wire from the relay to the plug on the fire wall the tab inside the plug melted and I wasnt getting a connection. I guess the pnly questions I have now are. How do I replace this plug without replacing or hacking up the wire harness? also how could this have happened could it of been from the black wire on alt. grounding out? Sorry about the quality of picture you can see the dark mark at the top right is where it got burned

Another melted wire.... Yeah, it may be because of that wire grounding out on the manifold.... As for replacement, providing it's a male connector, you should be able to push the wire in some, close the gap on the metal prong inside that plastic connector, then it should pull out.... Some times easier said than done..... Once out, cut what ever you need to replace, install a new prong on the end of the wire, and install it in reverse order that you took it out..... I tried to find a picture online of the terminal end that you'll need, but I've had no luck, it's basicaly a male spade connector, assuming that this is the male connector, and not the female connector. The female connector is about the same for all of them, it just a small piece that stick up just a hair to lock it in place..... To get that out, just take a small flat head screwdriver above the female connector (bewtween the plastic part of the connector housing, and the metal part of the terminal), and push the blade in some, it should make contact with the little part of the terminal that sticks up (should be in the center of the terminal) and push it down, then the connector should come out.... Also easier said than done.... Maybe this helps, or did I just confuse the mess out of folks? ??

Red wire from the relay to the plug ? a fuse link should it be before the red wire!!!! I fact the eyebolt terminal to starter relay is attached to the fuse link ( look at the attachment I posted above ) what I see melted is really the inner gasket. Plug itself could get some heating, but maybe not baddly melted Male terminals need to be bended at a side to get the retainer off the plug and pull it from back. Maybe in the past somebody removed and didn't fit propperly relocating the side tab on its position to clip and keep on plug you can see here how the terminal is and where to bend at a side to remove the terminal... Clean it and relocate the side tab, or arm or whatever could it be called. Is part of the same terminal how it is the bulkhead cavity ?

This thread is turning more electrical, so decided to move it to the propper section... then after solve this power problem, will check for backfiring if electrical or another kind

Ok so last night I went to napa and got a new terminal. The one that was in there was fried nothing left of it. once I put the new one in the car started right up and ran good. I did notice that there was no fusible link before the bulk head (Thanks Nacho) so I installed one. I am guessing that this happened when the wire at the alt. shorted out then it fried the terminal at the bulk head due to no fusible link. since this happened during acceleration I am guessing that the back firing was due to lack of spark. I had the car running and it ran smooth I checked the timing and its ok it was good to hear that big 440 purr well not really purr more like roar. I want to thank everybody who helped me out by giving me ideas and telling me where to look for thing. it made the job a lot less frustrating. I'll update after I take it for a ride.
