- 2001 Explorer Sport Trac
Howdy, so I've become relatively well versed with the 4.0 SOHC, I ripped one out of my brother's sport trac (2001) and I put it in my sport trac (also 2001). Mine had the very very common timing chain issue where they simply get loose and also my transmission was barely staying into gear on the third and fourth. In fact over drive was pretty much not a thing. So when my brother totaled his truck I decided that was my chance to fix my truck. His timing chains were just barely starting to show the signs of the timing chains going. So I took and rebuilt it and then stuck it to it's transmission (which was golden) and I threw it in my truck. Obviously it's the same model and year so it should pretty much be plug and play. I got it all in and I have compression and fuel at the rail. But it doesn't start. It cranks pretty slow but my dad (an ASC certified mechanic) said he thinks its just because there's no oil and it'll be okay once I get it running and the oil pressure goes to normal, which makes sense to me.
Here's where the post actually begins.
My problem is that I have it all together but it doesn't run. It has fuel and compression. But no spark. We laid a spark plug against the block and there is NOTHING for spark. Does anyone know why this would happen? I have everything connected but the alternator (something happened with the three pin connection and I'm working on fixing it. I've stared at wiring diagrams for quite a while and there MIGHT be a problem with that three pin not being connected as far as telling the ignition coil not to go. Do you guys think that might be the problem? Any other suggestions?
Thanks for all you guys have done for me because you guys have answered questions for me many a time when I rebuilt that 4.0.
