No crank no start

Awesome time response much appreciated, but the problem is the control I am getting 3.4 volts at the solenoid when ignition is in start position therefore not engaging solenoid. I am leaning toward plausible faulty ignition but want to be sure that I am not missing something along the way like PCM or vehicle immobilizer but there are no signs of that being the case.

George, I have pretty much exhausted all my options short of tearing dash apart and checking the ignition switch. I don't believe it is sending power to start circuit ECM is not supplying ground signal either. So I do believe it is ignition.

The starter relay circuit shows 3.4 volt on pin 1 and 1.4 volt on pin 2 I believe I am not at shop at moment I have a funeral to attend this AM but will clarify when I get back to shop. The relay should show 12 v on one and ground to the other if I am correct when ignition is in start position. There is no change on these readings in run or start they stay 3.4 and 1.7 no continuity to ground when trying to start and no voltage to opposite side of relay. I can start car with ignition on and power probe to start sol fires right up?

KaseKenny1, bud don't know if you are still getting my messages. I was wondering if you could possibly send a complete wiring diagram of start circuit? I appreciate what you have sent but the circuit is incomplete in both photos and I don't believe that they line up to show termination of all circuits do they?

No worries my friend. I also am on east coast well west coast of Florida but I sure don't want to press anyone it's great that these sites exist. I have looked locally here for service manual and yeah that ain't happening without special order. I really don't have 3 days to wait for manual that more than likely is not going to tell me anything I don't already know other than wiring diagrams and I would imagine if I stayed on it that would not be an issue. It really amazes me the multitude of electrical issues that this particular model has. I mean from its inception the focus seems to be plagued by mysterious electrical problems that elude even the best of us as a fix for one vehicle more than likely is not going to be fix for another with same symptoms. Anyway as I said no rush don't stress it if you can get them to me early great if not I can wait you are doing me a huge favor and I thank you very much. Now get some rest my friend and I will chat with you tomorrow.

I think I can say it is neutral safety circuit. I can't seem to find a schematic on it and have no idea what the resistance values should be. So I am going to pull a few homegrown tests and see if we can narrow it down to that I mean this circuit is ridiculous the amount of stuff it must go through to actuate a solenoid neutral safety switch. Okay, I get that but why the PCM, BCM, TCM, MMM, lol. Just kidding but seriously the audio control module really and the ground what is that did we sell every darn thing to China because that looks like some Hyundai kind of stuff there. No wonder they have problems with that awful transmission, no ground.

Okay, I'm going to try this reply a 3rd time my phone keeps erasing it if I move even slightly driving me nuts this morning anyway. No it definitely does not complicate things at all I was already checking into the range switch and yes I thought it would function as a neutral start switch but I don't see where it ties into the start circuit this may be my problem but as you can tell for some reason the ingenious minds at ford have found the most ridiculous placement for a control module that they could dream up! The plastic cover for this was warped and open at top but not bottom and we have had several days of hard rain here as you can see when I pulled cover gravel and sand poured out I am going to go out on a limb and say that water was in box as well. I removed the cover from junction box and checked wiring there and only thing I came up with that was not functioning was return signal from PCM on circuit 33&34 at junction box so does the PCM have total control of power and ground on those two wires or does it rely on a signal from the range switch to allow power and ground to those circuits? I am trying to avoid pulling PCM apart but may be doing that real soon. So if the range switch has a part in allowing the signal from PCM is there any way you could send the schematic for this or literature which ever is easy for you? And let me say your help with this is invaluable and greatly appreciated.

Too late already. Disassembled and found a few burnt resistors but have found a way to bypass it for the moment until we can get new PCM. I certainly do appreciate your help with this I am at a loss with Ford decision to install such a delicate piece in front of tire just really dumbfounds me. Although after being in this business for 30 years I have seen a lot of things that those of us who turn wrenches find just ridiculous.

Yeah, I really appreciate your help with this and low and behold Ford has numerous recalls on this particular vehicle. I did what I needed to do got the car up and running took it for test drive did great until I pulled back into shop and nothing. Transmission went dead, so I turn off wait, crank back up it goes into gear. So I pull it into shop no reverse and that was a hit and miss so I checked the recall info a little closer and yep TCM is definitely a part of recall as well as a few other things including software updates to PCM for no start or stall conditions directly related to TCM. So she is at Ford getting recall work done. Hopefully if I have any other issues in the future I can talk with you again. Thank you greatly.

After taking to the local dealership the TCM was indeed the issue! There are multiple recalls on this particular model so I strongly urge anyone who owns one of these to take to your dealer asap. The extended warranty program is only good until Sep 2020 and 120,000 miles if I remember correctly. No cost to consumer if within this time frame there are updates to software that need to be done to PCM, TCM my customers vehicle had to have TCM replaced. As well as software updates to PCM to correct the problem which started out a no crank no start and ended up with no reverse and a transmission fault and this particular trans is known to just kick out of gear driving at any given time which can be extremely dangerous so please take to dealer and have updates done

You're very welcome. I have a new one for you but can't seem to get to the new question area.
