Lol that will do it for you...I got the water at a off brand gas station,do not go there anymore,problem solved

All second gens, regardless of motor, are wasted spark. Same with any 3rd/4th gens with the 4.0 SOHC engine. I think the 4.6 was the only one that got coil-on-plug.
No vacuum FPR on the return-less systems (99-01).
One wire per plug is not the best indicator of a waste spark system. Waste spark basically fires two cylinders with one computer pulse (one on the compression stroke and the other on exhaust) and it has to do with how Ford decided to control the coil pack (it's easier, cheaper, and requires less programming to fire two cylinders with one wire). Distributor style EFI systems with one plug per wire are also not waste spark.
If there’s no spark why does the one bank always have much higher wear?"Waste spark" system was a neat idea: half the number of coils and no need for camshaft-driven timing (at least not for ignition). The transition to coil-on-plug killed it, eliminating the failure-prone HV wires.
BTW, "waste spark" is a misnomer. There is no spark in the opposite cylinder, because its plug is practically shorted by the high water content in the exhaust gas.
Because the current flows in opposite directions - in one bank from the center electrode to ground; in the other bank it's the other way round. Or, if you will, in one bank the firing voltage is positive and in the opposite it's negative. I am not sure which is which, but it's not too hard to figure out. Material erosion depends on which way the electrons go. That's why OEM plugs were different PN for opposite banks. Aftermarket plugs are usually all the same, and both electrodes platinum coated.If there’s no spark why does the one bank always have much higher wear?
I keep wondering about that but garage claimed nothing was wrong with itFuel pump.......
definitely got a point there, I found some other testing I can do on the fuel pump, I’ll let you guys know what solves my issue, might be about 2 weeks till I’m able to try and tackle the fuel pump, from what I seen it can be a painThey also claimed they fixed it.
Yep gotta check it while it's hot and acting up
I went through this for like a year Is my fuel pump bad 1999 ford explorer shoc 4.0. Lots of pictures on the replacement
