I have an AutoXray 6000 and it gives Cam Position Err. Would this cause flooding? The engine does make an attempt to start, but to no avail. Only a few fires and leaves the plugs soaked with fuel.

OK, this is what I found out today

OK, this is what I found out today

Thanks for swift reply.

Forgot to note. New coolant sensor, spark plugs and wires. Temperature guage in dash is in middle all of the time ... cold or hot.

Today I can:

unplug the coolant sensor (on top of the thermostat housing, btw - coolant sensor works properly) hold accelerator pedal to floor and car will start. Rough idle, but it will start. Plug coolant sensor back in and idle smooths right out.

OR

unplug coolant sensor, short across wiring harness to make computer believe car is hot and car will start. Again ... rough, but it starts. Remove the jumper and plug the sensor back in and engine smooths right out.
What could cause this ... not starting with the coolant sensor plugged in?

I almost forgot ... when running, camshaft sensor err is 0 Degrees.
Also, it looks as though the wiring harness is in good condition.

The data posted is in Open loop (engine not warmed up) and not very useful other than your Throttle Position Sensor is working and your Camshaft Position sensor is not working. Check/change CMP and wiring and see if it improves.

Edit. Assuming that the car was idling and the steering wheel was close to straight, the Power steering switch is working too.

OK, will check CMP wiring again. Car is not here. Will post tomorrow. But here is data downloaded today.

I'm not familiar with short and long term fuel trim. Could I be enlightened, please?

Good reading material for fuel trims here. Cliff notes- SHRTF for temporary engine conditions. Engine switches parameters in LONGFT if SHRTFT has issues which cannot be corrected by PCM in the temporary period.

http://www.v8sho.com/SHO/TSB0197HO2SServiceTips.htm

I suspect your "wacky" SHRTFT and ECT numbers are due to you unplugging the ECT. I suggest you go the CMP route first and see if it helps. If that doesn't, I would look at cleaning the IAC valve. Post again after you try those suggestions.

Edit. Zetec IAC valve cleaning

Zetec IAC location.

For the Zetec I-4, you need to access the IAC from the bottom of the car.

IAC cleaning
from Ray's UIM/LIM how to in Duratec Maintenance how to.

"Replacing the IAC gasket:
(From IAC faq)
Over time, the IAC (Idle Air Control) valve becomes sticky due to buildup from the EGR and PCV systems. It can stick partially open such that idle quality is adversely affected, and engine RPM's will not drop below 1500. For a while, blipping the throttle will restore normal idle, but this only works for so long.

The fix is to remove the IAC valve by unbolting the two 8mm bolts that hold it on and disconnected the wiring plug. If you are careful enough, replacement of the gasket will not be necessary. The gasket costs less than US $1.00, so it is no tragedy if you destroy it. Once the valve is off, spray it out with some carb/intake cleaner and make sure any gunky residue is gone. Reattach, and you are done. It is a lot cheaper than a new IAC, which runs around US $70. Note: Ford claims the IAC cannot be cleaned, but this is not true in my experience." Ray.

Location of the IAC for the Zetec.

"It's on the back side of the intake plenum under the throttle body area." DESIGN.

I looked at the Haynes manual and the Zetec IAC valve is located next to the starter. Below are the steps from the 1996 Ford CD to remove it .

Idle Air Control (IAC) Valve


Removal

1. Disconnect battery ground cable

2. Remove the air cleaner outlet tube and resonator assembly.
3. Disconnect the main chassis vacuum line.

4. Disconnect the ignition coil and radio interference capacitor wiring.

5. Remove the fuel line bracket retaining bolt.

6. On 2.0L engine equipped vehicles, raise vehicle on hoist.
7.
7. Disconnect the engine control sensor wiring or fuel charging wiring (depending upon application) from the idle air control valve (IAC valve) at the idle air control valve connector.

8. On 2.5L engine equipped vehicles, remove retainer for engine control sensor wiring from the upper retaining stud bolt.

9. Remove the two idle air control valve retaining bolts or stud bolt (depending upon application).

10. Remove the idle air control valve and idle air control valve gasket.

Installation

1. Note: If scraping is necessary, be careful not to damage idle air control valve or intake manifold idle air control valve gasket surfaces or drop material into intake manifold.

Clean idle air control valve gasket mating surfaces.

2. To install idle air control valve, reverse Removal procedure. Tighten the fuel line bracket bolt to 8-12 N-m (71-106 lb-in).

3. On 2.5L engine equipped vehicles, tighten the retaining bolt and stud bolt to 8-12

4. On 2.0L engine equipped vehicles, tighten the idle air control valve retaining bolts to 8-11 N-m (71-97 lb-in).
