Question about 2000 Ford Focus

1 Answer

2000 Ford Focus ZTS 2.0L DOHC cranks but won't start. Have tried crank sensor and PCM w/ key and transponder module. There is no coil driver getting to the coils (either one) to make spark. The pcm is receiving a good signal from the ckp...I scope tested it and tested all the wires between pcm and ckp and coils. Also load tested and ensured proper continuity on all the power and ground circuit to the pcm. I scope tested the cam and crank sensors at the same time and noticed that #1 cylinder seems to be at the same position on both sensors (same time)...is this normal? Also checked engine base timing (all OK). Performed all kinds of tests several different times; kinda at my wits end!!! Please help me. Any ideas or inside knowledge are welcome. Thanks, Dave.

I read no place in the post that you have performed an OBD2 fault code test, you must do that test first, it is the key to fixing all electronically controlled engine issues like this

SOURCE: 2000 ford explorer 4.0 x-engine is stalling, missing and lose power while driving

I personally would check the fuel pressure. Then I would go back to the coil. I have seen brand new bad coils out of the box. The symptoms of a loss of power point to this component, especially if the car idles well, but loses power when accelerating. Please do not rate this reply - we all are left to grasp at straws since you have changed pretty much everything. Good Luck. Please post the final fix of the problem.

SOURCE: rough running, erratic spark

Run a compression test on the cylinders.If reading is low on any drop a little engine oil into the pot. If compression rises you have compession ring problems. Remove all plugs before you try this and place leads away from engine.

SOURCE: PCM unit

PCM is the standard automotive acronym for Powertrain Control Module, previously know as the ECM and ECU, in 1996 the term was standardized for the new OBD 2 emission control system.

SOURCE: 1999 pcm problem

I am not sure I understand your problem but I assume the truck is not running , no power to pcm ect. I have had jeeps sent to me after thousands of dollars have been pured into them and still wouldnt start. Change the CRANK SENSOR. This will 99% of the time fix this problem. When you go to the part store just make sure to give them the correct info. it is located on top of the transmission bell housing and is held in by 1 bolt most of the time it is a 10mm bolt . it is sometimes a pain but its on the drivers side top of bell housing . look at the new one to get idea of what it is. follow wire harness and unplug then take bolt out and remove sometimes you have to twist and pull out. put the new one in put bolt back and plug in. if it has a piece of felt on the tip leave it on it will come off its self . jeeps have a lot of pcm problems but the crank sensor can fool even the best mechanics making it look like a pcm problem. I take it you have not changed pcm's. if you do it will have to go to dealer to be programed and flashed in order to stay running. but hpoefully you havent changed pcm yet and go ahead and change that crank sensor asap

No spark ferom coil


Probable Causes: Fuel Pump (P0230 to P0233) PCM (P0600 to P0606) Crank Sensor (P0355 to P0399) Fuel Pressure (P0190 to P0194) Chances are the Check Engine Light is not on, but you may find any of the following codes: P0230 to P0233 Fuel Pump codes P0600 to P0606 PCM related codes P0335 to P0339 Crank Sensor codes P0190 to P0194 Fuel Pressure Sensor codes No spark due to a bad crank position sensor, a faulty ignition module or PCM, a problem in the ignition circuit (ignition switch, antitheft system, wiring, etc.), a faulty park/neutral safety switch, a bad ignition coil (only on engines with a single coil ignition), or wet plugs or plug wires (did it rain last night, did you just wash the engine?) A less common cause is a worn starter that draws so many amps while cranking the engine that there's not enough juice left to adequately power the ignition system and fuel injectors. Contributing factors might be a weak battery and/or loose or corroded battery cables. No fuel because of a dead fuel pump, bad fuel pump relay, blown fuel pump fuse, plugged fuel filter or line, or failed PCM injector driver circuit or injector power supply relay. Or, the fuel tank might be empty (don't believe what the gauge is telling you), or the fuel tank might contain contaminated fuel (water or too much alcohol) or the wrong type of fuel (whoops, somebody put in diesel instead of gasoline). No compression because the timing belt or chain is broken, the timing belt or chain is loose and jumped out of time, or the overhead camshaft has snapped.

1997 Oldsmobile Achieva won't spark


id start by checking wires from crank sensor to pcm, using ohm meter, for resistance, or for open. at crank sensor connector, with it unplugged, probe each spade, one at time, with one lead and touch the other lead to good ground location. if you get a reading, you have a short to ground. if this is the case, i find it easier to run new wires from pcm to the sensor, vs tracking problem to its source. if you find no problem w the crank circuit, id first check wiring to coil housing, if it checks ok, try another coil tower, as i have got bad new parts in this same situation, on a quad 4. hope this helps. james white, white automotive, hopkins mo.

My 2000 ford focus cranks, but does not start. I


You will want to find out if you are not getting spark or not getting fuel.
If no fuel, then bad fuel pump, plugged fuel filter, or bad fuel pressure regulator, or bad fuel pump relay.

If no spark, then bad crank sensor, or ignition module, or coil packs.

Location of ignition control module


It does not have an ignition control module.
The electronic ignition (EI) for the 4.0L engine consists of the following components:
Crankshaft position sensor (CKP sensor) and 36 minus 1 tooth trigger wheel.
Ignition coil .
powertrain control module (PCM) .
Related wiring.
The PCM controls the firing of the coil based on the signal from the crankshaft position sensor.
The crankshaft position sensor (CKP sensor) is a variable reluctance-type sensor, triggered by a 36 minus 1 tooth trigger wheel configuration machined into the rear of the crankshaft vibration damper. The signal generated by this CKP sensor is called a CKP signal. The CKP signal provides the base timing and rpm information to the powertrain control module (PCM). Base timing is set at 10 degrees BTDC and is not adjustable.
If vehicle has no spark then turn key to on position,check engine light should come on.As you start cranking engine it should go out while cranking after about 10 secs. it should come back on(while cranking). If it come on then the PCM sees the signal,if it does not then PCM is not seeing it and this is your problem,either the CKP sensor or the wiring to it.
