Looking back on the videos I took, it seems that I have strong spark. The videos weren’t too good but it looked blue in some and a strong looking orange in another. It doesn’t look concerning, id think it would be plenty enough to ignite fuel.

Also, could the problem be the camshaft position sensor? Could that cause a no start? It looks MUCH easier to get to than the crank sensor so I might try that too. If not I can always return the part.

No, cmp sensor won't cause a no start. Will start but run poorly. Also, have never heard of a faulty cmp sensor on a Duratec and I've had 6 '98/'99's. When you changed the ckp sensor, did you inspect its elec. wiring harness closely?

It was hard to see in there, all it was was a plug then wires that went up. The part I saw seemed good, but I feel like there might be an issue there still. The tach needle doesn’t move at all when I crank, with the old or new sensor.

^+1. Yeah, tach should flinch a bit. Possible rodent damage? Iirc, wiring from the sensor should run to the pcm. Again, iirc, Rockauto online sells the pigtails or you can snag some wiring at a pick-n-pull jy.

Where does the wire go? Is it hard to replace? The engine bay is really tight on these duratecs from what I see.

Joel, I've never had to replace any wiring, only a couple of ckp sensors over the years. May pm member/admin. sousa632. Iirc, he's made the repair.

I did replace the ckp on my 01 Duratec however I didn't replace the wiring. If there was a need to replace the wiring it's more than likely going to be the harness end on the ckp that needs replacement due to oil infiltration. If it's dry, it more than likely doesn't need to be replaced. If the ckp was an issue you would get NO spark at all, but you are saying you are getting spark so that rules that out. Start with the fuel pump issue(check the fuse and relay first) then move on from there. Also check your battery voltage. Low voltage can wreak havoc on a modern electrical system.
