2.5L ('98-'01) 2000 Ranger 2.5L Manual transmission

[1999 3.0 ranger]

I am working on this 2.5 and I have a crank but not spark issue. I’ve spark tested and have none at the cylinders. I’ve replaced the crankshaft position sensor, I have power going to the coils, the coils passed the ohm test. My last idea is the camshaft position senser. Any ideas?
Plus: does anybody know what the ohm spec for the camshaft position sensor is?
Thanks

From the manual;


During basic operation, the powertrain control module (PCM) (12A650)determines the ignition timing required by the engine (6007) and determines which ignition coil (12029) to use.

The camshaft position (CMP) sensor (6B288) is used only for fuel charging. This sensor allows the sequential fuel injection (SFI) system to inject fuel in cylinder firing order; refer to Fuel Charging and Controls — 2.5L.

REFER to Diagnostics for further information on ignition system components and their functions. Refer to the Wiring Diagrams for ignition system wiring diagrams.

Ignition Coils

Two ignition coil packs are used for the 2.5 twin-plug engine. The two ignition coil packs are triggered and timed by the powertrain control module. Each coil pack contains two separate ignition coils for a total of four ignition coils. Each ignition coil fires two spark plugs (12405) simultaneously, one spark plug on the compression stroke and one on the exhaust stroke. The spark plug fired on the exhaust stroke uses very little of the ignition coil's stored energy. The majority of the energy is used by the spark plug on the compression stroke. Since these two spark plugs are connected in series, the firing voltage of one spark plug will be negative with respect to ground, while the other will be positive with respect to ground. Refer to Diagnostics for additional information on spark plug polarity.

Spark Plugs

For production and service in 1998, all eight spark plugs are AWSTF32-F.

Dual Plug Inhibit

Dual Plug Inhibit (DPI) is a function of the powertrain control module that is used when the vehicle is being started. During engine cranking, the powertrain control module will only fire the spark plugs on the right-hand side of the engine.When the engine has started, the powertrain control module will start normal twin-plug operation.
