Question about 1999 Ford Explorer
The truck started easy like any other time i started it i drove about 200 yards and i could hear a wineing noise i shut the truck off after checking under the hood i noticed the tension pulley was broke so i started it and put it in reverse to back up the engine died as soon as i put it in reverse now it wont start and now it seems the engine turns over fast i have plenty of fuel pressure and it has spark from the coil pack. any help with this truck i would be greatfull
The timing may now be out as engine moved after the pulley had broke , have the timing checked, if it's turning over very fast the timing belt may have broken so the starter isn't turning anything !

While I was patching the holes in my oil pan today and waiting for the JB Weld (another story in itself) to cure I inspected the area of the relay control module (fuse box) because I had some luck previously moving things around there and getting it to start (see above). I found that I had previously repaired and/or upgraded the the two smaller wires coming from the neg. cable. One goes to a connector and if I remember correctly on to the fans (I remember tracing it previously--dont remember where to) and the other to body ground--I had soldered the wire to connector and bared surface on body to make a good connection. As I mentioned I zoomed in on the fuse box and found that the large pos. cable goes to the starter and there is a relativly large cable going to the fuse box where it is bolted onto a plate/connector that then allows the current to travel through a fuse link (that runs under the module) into a rather large wire going --somewhere--. The plate seemed to be made out of some aluminum alloy. I removed the nuts (after disconnecting the battery of course) and found some corrosion on both the nuts and the plate. Wire brushed both (with drill and wire brush---took much more cleaning/brushing than I expected) I cannot say if this fixed this or not as our problem is sooooo intermittant. I didnt follow the fuse linked wire and as I type this I am wondering if there is such a thing as an intermittant fuse link. (I remember wanting to junk some chryslers as a kid)

Since you are getting spark and fuel we know you are good there. Check the timing on the engine. Turn the engine from the front of the crankshaft with a socket and a large breaker bar until you reach top dead center of the intake stroke. Then remove the distributor cap and check to make sure the rotor is pointing to the # 1 cylinder. It almost sounds from your description of the sound the engine is making that the timing chain has jumped a few teeth on the gear. These factory gears have a nylon coating on the teeth and over time the nylon chips off the gear. When to much of this plastic gets chipped off the teeth it results in chain slack on the push side of the gear. When you shut the engine off it can jump a few teeth at the very last second before the engine stops rotating the crank and cause it to jump teeth. The engine probably has high mileage and might need the timing gears and chain replaced now. If you perform the visual check with the distributor I think you will find the chain has jumped a few teeth. If you need more help come back to this site and one of us will be glad to help. Good luck. Let me know what you discover.

good old ford lol, try looking at the crank sensor its located at the front of the engine tucked in right hand side of exhaust manifold and gearbox, two pin plug, i have also known these to have no end of faults with the fusebox.
easy to remove, and solder the connections inside they all suffer eventually, if your not to handy with cars i recommend taking to a auto electrician, easy if you know how. Good luck Davelee
