Default 1994 ford ranger not starting

My friend has a 94 ranger with the 4.0 and it will not start.

Yesterday he had someone he knows replace the valve covers for him since they were leaking oil really bad. He also replaced the plugs and wires.

Now it will not start. I helped him pull all the plugs to recheck the gap and to make sure the wires were all connected. Everything there was fine and you could smell gas on the plugs. He said he tried using starting fluid and it still wouldn't start.

So I figure it must be electrical because it cranks like it wants to start but it won't.

If I missed any info that may be necessary , sorry.

Any input is appreciated. Thanks.

so it ran fine, then the valve covers were removed, and now it wont start? look for something left unplugged, or plug wires installed in the wrong order. It is obviously something done when removing the valve covers.

coil pack plugged in over passenger valve cover?

Check for spark at one of the cylinders...if you've got it, make sure the wires are routed from the correct coil pack positon to the correct cylinder.

The upper intake has to come off to do the VC's on this motor - are all the vacuum lines correctly hooked up to the rear of it?

MAF sensor plugged in?? Air intake was likely removed...

Possible vacuum leak at upper intake gasket...


Those are about the only things I can think of going wrong when you do this job....

Could not find a bad vacuum or any unhooked wires. Had voltage at the coil pack and replaced it just to be sure it was good.

I checked the check engine light since it is OBDI and it brought back the 3 digit code 5-2-2 which is Park/Neutral Position (PNP) or Clutch Pedal Position (CPP) circuit fault - PNP
transmission MLP sensor out of range in park - Transmissions.

It is a manual so it not reading the clutch would make it not start.

Anyone have any experience with this issue ? How to fix it ?

Thanks.

Could it throw this code for no reason ? Or is it just a freak coincidence that it failed at this particular time ?

So I found this plug unplugged on the back of the motor :





Any ideas what it could be ? I thought maybe crank position sensor but , autozone shows it looking flat and not round.

I also thought the 4.0 CPS was on the front of the motor but , google is giving me conflicting answers and pictures.

One more question , is the clutch pedal position sensor on the pedal or on the transmission ?

Sorry for all the noob questions , I am normally a GM guy.

Thanks.

Connector is on the passenger rear of motor, right?? IIRC, there is a connector under the bracket that the coils sit on....being a two wire connector, it very well could be the inline connector for the clutch switch. It's just a two wire dumb switch I believe...open or closed, depending on clutch position

Also, I believe the clutch position sensor is on the pedal assembly (have a stick in mine, but don't have a switch...used to be an auto)
