2000 Ford Windstar 3.8 litre - No Spark

Hello Members,
Greetings to all.

I have this 2000 Ford Windstar 3.8 horse power with issue of NO SPARK, NO INJECTOR Pulse..

I have tested the crank sensor and it is okay.. the theft light is not flashing nor solid- means when key turn on, the theft light also comes on and goes off, engine crank alright but no spark..

when key is turn off and turn on again to crank, the injector light flash once and it wont flash again, this means injector flashes only once and wont flash again but NO single spark at call..

tested for coil harness and had one IGNITION CURRENT, WHEN KEY IS TURN ONE, fuel pump works alright..

so i am here to seek for advise what could be the culprit..

secondly all fuses both underhood and dash are intact..

p1000 code in pcm only..

disconnected tps, map, idle control valve but to no help. needed help.

thank you for stopping by to read my comment

Did you check the camshaft sensor? You mentioned that you tested the coil harness and had one ignition current. Does this mean that you saw only one current ramp when you were cranking? DId you check all of the coils for spark?

You also mentioned that your injector light flashes when the key is in the cranking position but the flashing stops. Is this correct?

None of the Coils spark, as matter of fact the ignition current is active on the coil harness while engine is being crank, but no spark, the injector also give out lite once when you start cranking.. i have not tested the CAMSHAFT yet because i belief supposing the cam isnt good, like there wont be one noid light flash on the injector harness... remember the engine has constant current at one side while engine is cranking...

and when i disconnect the camshaft sensor and i crank, there is no flash light on the injector, i mean the earth which comes from the pcm, does not come, likewise to the crank as well.. if you disconnect the light wont flash..

i am suspecting something fishy like theft system but the theft light is not blinking or not solid on, it as soon as key is turn on, the theft lite come and goes off, so i dont know why this should give out light once on the injector and goes off

Can you explain what you mean by ignition current? Are you seeing actual current flow to the ignition coils? Can I confirm that you have a constant 12v power to the coils and injectors with the key in just the On position (not cranking). Can you also confirm that your fuel pump is turning on when you are cranking? Does the check engine light go out when you start cranking?

I'm also confused by your meaning of current. If you're measuring amperage at the coil (not voltage) but have no spark, that suggests that the inputs are good and the wiring to the coil is good but the coil is not.

Sorry for using the wrong terminology, it rather there is ignition power or let me say positive juicy on the coil side

Do you have power to the coils and injectors with the key in just the On position (not cranking) ? So you know if the fuel pump is running when you are cranking? Does the check engine light go out when you start cranking? Sorry for all the questions but I'm trying to work out whether the PCM is getting an RPM signal.

There is power oon the coil and injector line, when key is turn on, and when key is in cranking position, the power is stay, unless you turn the key off completely before you will no more find power on the injector and the coil side... remember the coil side has one power, then the rest of the other lines are the triggering earth from the pcm, but this triggering does not come, and the injector earth triggering also flashe once anytime you attempt to crank by turning the key from off to crank position..

the pcm gets rpm for a while then cut off on the autel ds708 which i belief it is because the scan tool cannot keep constant look at it, unless scope but i dont have scope. the cam also you will see it triggering from High, LOW as you crank, you will see it on the autel tool..

I think we need to find out whether the PCM is actually losing the RPM signal. Can you measure voltage at the fuel pump when you are cranking and see if you lose the voltage? I'm not sure at the moment why you momentarily have injector pulse when cranking. It sounds like a symptom but I'm not sure yet.

I don't lose voltage on the fuel pump when car is being crank...

When I crank and look at the cam live data, I see it high and low as the engine turns , the rpm also reads for a while and then stop, for this I suspect may be the autel cannot keep up with the fast digital data, unless scope but I don't have scope for now.

No theft light blinking,

When the engine is crank, i don't see rpm signal on the scanner while cranking, some times it com once and goes back to zero and remains there...
The number of wires to the crank and cam sensor are 2 each, so crank sensor 2 wires, cam also 2 wires, and this sensors are the hall effect type, so i am able to use DMM to take readings of it from the ECM side, Here is the video of the sensors and panel info

So your fuel pump stays running the entire time you are cranking the engine? This is a VERY important piece of information at this point. We have to be 100% sure on this.
If the pump continues to run, this confirms that the ECM is receiving an RPM signal the entire time and not losing it.

The cam signal is not needed on this engine for spark to take place....i'm not 100% sure on that but almost

These computers do not go bad often, but I have replaced at least one Ford computer on a waste spark system where it was not firing the coils. But I don't remember if it was all three or just one.

The other thing I do not like is your injectors are also not firing properly.

Can you tell us if you are losing the 5v ref while you are cranking?

Correction - The fuel pump will only run for a few seconds then off, when the key is cycled from OFF to ON, so this is priming . But it stop when you re cranking it does not push in fuel into the rail anymore... secondly i checked my 5v while cranking and it stays ON , while cranking

my injector will sometime come on once and goes off, as if timing issue or immo issue but all the same i have no P1260 code nor anything related to immobilizer code in the cluster..

Scan tool is able to communicate to the ECP, to the PAT's MODULES, and all other modules on the car...
But when battery is taken out and refix, sometimes U code such us U1262 or U1147 comes in the Cluster, Front electronic module, ABS.
But when you clear them from all this module it goes never come back until battery is disconnected before this codes will set...
Owner had the cluster changed from different place because was told it is cluster and ECM setting this code.
But the above codes do not appear in the ECM, and there is no security code appearing in the ECM, the only code in the ECM is P1000.
You will only see this two codes in those modules i mentioned above but it wont appear in the ECM when scan

Your PCM is not receiving an RPM signal if the fuel pump doesn't turn on when cranking. I note from the video you uploaded that the check engine light goes out immediately when you start cranking. On Ford systems this usually means the PCM is getting an RPM signal. You're also seeing random RPM data on the scanner at times. Do you have live data for the crank sensor?

I noticed that you were using a multimeter to check your sensors which are variable reluctance sensors. You really should be using a scope to check VRS sensors. From the video it looks like there might be a bias voltage on those VRS sensors. Can you tell us the voltage reading on the 2 wires with the connector plugged in and Key on, engine not cranking? And what voltage readings do you have on the 2 wires with the connectors unplugged?

Those U codes are communication errors. It might not have anything to do with the no start
