i have a mk2 xr2 to which i have fitted a 2litre zetec from a mk1 mondeo along with its engine management loom and ecu, everything is finished but there is no spark at the plugs, i have tried another coil pack which has made no difference what i would like to know is what does the ecu rely on during cranking to fire the plug, is it simply the crank position sensor or or other sensors involved?
hope you can help, or a have some ideas, i have checked and double checked the loom connections to the ecu and its sensors and my friend whom i consider good at electronics has also checked everything and says he cant find anything wrong. i know the best thing would be an auto electrician, but i am skint, and know its probably something simple.
thanks ppl

I had to sort out a similar installation in an XR3i last year. Did you use the Mondeo flywheel? This one hadn't and the XR3 flywheel has the reluctor cast in a different position to the Mondeo so the crank sensor wasn't 'seeing' the reluctor and didnt know the engine was turning. The Escort clutch fits straight onto the Mondy flywheel.
Check for a 12v feed to the coil pack and make sure you have continuity from the two pin connector to the flywheel sensor to the ECU. As you have fitted the complete Mondeo loom there is a diagnostic socket which may help.
Recommend you try and find a Turbo gearbox as the standard Escort box lasted a fortnight!

thanks for your reply, i used a 1.6 16v zetec escort flywheel, because the 2.0 mondeo one does not fit in the rst bellhousing (alreday got an rst box, cos i transplanted a complete rst engine into the car about 2 yrs ago) are you saying that the escort and mondeo zetec flywheels are different. i used a crank sensor from a 1.8 105ps orion, cos the 2.0 was broke. i have continuity between the crank sensor plug and the appropriate ecu pins and have connected an ohmmeter across its terminals while cranking and it shows 'something is happening'.
I have already purchased one of those diag readers, it come back with 327, 519, 565 and some others, but these are all related to things that are not connected like the power steering pressure switch and some egr sensors, cannister purge solenoid, ecu driven fan relays, but i cannot see these things not being connected causing a no spark condition?? There is 12v present at the centre of the coil plug and it drops to about 8v while cranking, is this acceptable, bearing in mind the battery is in the boot??
thanks for your help in advance.

What's the voltage on the outside pins of the coil plug;these should rapidly change from 8-12v to 0-2v to make it spark;however you need a good multimeter(fluke 88 or similar) to be able to record max/min.

hi i have not checked this, i have an ok digital multimeter, would an anologue meter be better??
do you know if all the cps are the same across all the mondeo/escort/orion range? i have another mondeo zetec engine in my shed and it has a different style of cps, it is bolted differently?
cheers

My fluke 88 is a digital;don't know what your's can do;any coil pack should work;all the normal ones are 12v but you need the voltage switching to near zero to trigger the spark-I once used one side of a Ford coil pack to run a 2cv.

If you remove the sensor you should be able to see, with a mirror and torch, the cast ribs directly inside.(I think there are 60 of them but I have never counted them). I know that the sensor is mounted in a plastic block and these may differ from engine size, the parts dept at Ford should confirm this if they list different part numbers according to size. You can check output from the sensor by measuring ac volts across the sensor and the simplest way to check for switching is to put a low wattage bulb across the centre and each side of the coil.It should flash as you crank. By the way the Mondeo-into-Escort now sports a supercharger from a G60 Golf...needed special pistons and a lot of engineering..............!
Put a Chevy in it and rear wheel drive I say!
