IF you own a V6 gas Ranger, regardless of the year or the engine size they have actually a the majority of things in common and just a few differences.All V6 Rangers have actually the same firing order, yes the 2.9, 3.0 and 4.0 of all years. The firing order is 1-4-2-5-3-6.If you room looking under the hood native the front grill, on your left side room cylinders 1, 2 and 3 in the order and on the best side you have 4, 5 and also 6 in that order. Cylinders 3 and also 6 room closest come the firewall, cylinders 1 and 4 space closest to the front of the truck where you space standing.In the at an early stage distributor electric motors the rotor transforms clockwise looking at the top, that should suggest at #1 wire around where the compression hit is ~ above cylinder #1 and also from over there clockwise 4-2-5-3-6 should follow in that order.Then comes electronic ignition :).From about 1990 come 2011 in the USA the V6 ranger only used 2 different coils. It is uncertain why there were 2, if you understand what they do you can interchange them however do not shot until you have read the whole article. There are coils with the socket for the plug suggest upward (referred to together vertical) and some pointing exterior on the next (referred to as horizontal). The safest method if you room unclear is come buy the one sharp in the exact same direction that come off her truck. But the horizontals space usually easier to discover than the verticals, over there must have been more of castle produced. Supply meets demand.The an easy electrical diagram for the coil is below, that is expected to show more what the coil walk than particular wiring yet even if friend don"t typically read schematics it makes perfect sense:So yes, every plug fires double as frequently as it requirements to. 3 and also 4 fire at the exact same time always, 2 and also 6 fire in ~ the exact same time, 1 and 5 fire in ~ the same time.Looking at the coil, you will watch 3 rows the 2 sockets each, the horizontal is shown here:There are just 3 coils in this pack. Look in ~ the numbers compared to the schematic above.If they with you have the right to take the plug wires turn off the coil and also exchange 3 through 4, and/or 2 with 6 and/or 1 v 5 with no adverse effects to the motor running. The wires could not with the various other location however if it does it will still run.Here"s wherein it gets tricky... This is the upright plug coil:At very first glance you to speak "hey every the wires are in the exact same place!" but look at whereby the plug goes in. The "IGN START/RUN" is top top the very same side of the tab in both coils however the "CD2 and also CD1" are inverted in the pen order through CD3 gift in the same ar on both plugs.Ford threw a wrench in come this too! right here is why.. (read carefully) CD3 in reality is the link to fire the center 2 sockets labeling 2 and also 6. You would certainly think since it is labeling CD3 it would go to 3 but it does not.So does CD1 walk to 1 and 5 or walk CD2 walk to 1 and 5 in the diagram? honestly I have no idea! ns will reduced one open eventually but for swapping functions it doesn"t matter.For either coil the center 2 spark plug wires stay the same. If you gotten rid of a vertical plug coil from her V6 and put a horizontal plug coil on out of requirement or lack of availability, you take the spark plug wires that are on 1 and 5 and switch them v the persons on 3 and also 4.In the other direction if you have a horizontal plug coil and also all friend can uncover at the scrap garden is a vertical format to change it with... You take the spark plug wires that are on 1 and also 5 and switch them with the ones on 3 and also 4. Same specific thing!If anyone knows for sure which 2 CD1 and also CD2 goes come please include to this thread. The an initial truly swollen one ns come across I will cut it in half and recognize for sure.So over there you have actually it, this is no theoretical I in reality did this and it does indeed work. ;)____________________Truth sounds choose hate for those who hate truth.00 XLT 4WD RCSB 3.GO!
