Not getting any spark how do i pinpoint the problem

What engine does it have? V-6 - V8

Looks like one bank of cylinders are dead.

When you see these codes , it's time to worry . These ford coil on plug system's can fry the transistors that control the coil firing . New computer or reman at ford $ 800.00 buck's then it needs to be programmed (dealer) What engine ? 3.0 v-6
This happens when the spark plug's are neglected , gap get's to wide , make's coil's over heat an break down , spark goes through the primary wire to the computer . Your best bet , take it to a qualified repair shop.

get the OBD read ,could be a few things , the codes should pinpoint it for you

ECM requires both crank sensor signal and cam sensor signal to fire the coils. Check for spark at the plugs first. Check the plug wires, then the coils. Only if you have no spark at any coil would I suspect the ignition module, and even then only if you have a good crank and cam signal. Do you have any codes stored in the ECM? They could help pinpoint the problem.

does it turn over but not spark ? if so i'd get the OBD codes read as possably a sensor/switch etc this help will pinpoint the problem

when the computer sees no ignition spark going to the spark plugs, it shuts down the fuel system. it wont keep sending fuel and injecting it because the cylinders would have too much raw gas accumulating. the gas would end up in the oil. very bad. so first, see if you have spark at a plug wire. if there is, inspect the plugs, if theres not, get a code reader and do things right. dont unplug anything else. read the codes in the memory. write them down. clear the memory. service the codes that indicate loss of ignition first.
this car may have been in LOS (limited operating strategy ) till the plugs fouled. the LOS is caused by system faults that required correction for too long. now, with new plugs, and the memory erased, you can run codes again to see whats at fault when you try to start. if theres no spark sent to the plugs at that point, then the pinpoint test is valid to run for loss of spark. dont forget to change the oil !!! report your findings or discuss it with your tech at the ford dealer. so many erroneous tests, codes and confusers may come up that he runs your vin and finds tsb info you may need to clear this up.
after the memory has been cleared you could have fewer codes, one code or no codes. now put a test light on an injector to verify pcm signals are going to the injectors. dont replace parts that dont fail pinpoint tests

Hi Alan, Have the vehicle scanned with a diagnostic scan tool. The problem may be a crankshaft or camshaft pickup sensor. The scan will pinpoint where the problem is. Regards John

Actually a fuel pump can work,but the injectors are still being blocked from getting fuel.I'd talk to FORD.They've probably seen this a hundred times.I had it happen once on my focus,but we never pinpointed the problem. don-ohio

Check each spark plug to see if you are getting spark to each cylinder. If not, then check coil packs or distributor.
If you are getting good spark, check to see if you have fuel pressure in your fuel rail and that you can hear the fuel pump humm.
If you have a check engine light on, you may have a faulty sensor and you should have your engine codes read to pinpoint exact problem location.

raise hood follow wires from spark plugs if it has wires, most of the newer fords have coil packs for each cylinder and are actually mount on the spark plugs, these are prone to failure at some point, The coils break down. they cost around 45.00 each to replace. If you are getting a misfire, generally you will find the one it is by running diagnostics to pinpoint which cylinder it is
