mk2 escort st170 on omex 600 car been running fine for weeks wired alternator up yesterday checked it drove it all charging ok. drove this morning parked up came back to start it an wont go battery changed etc... pluged in laptop - stat syncd not on (which it should be when cranking) tried usual going in to user advanced alter by + or - 15 - no diffrence - cranks sensor reading ok, tps working as are all other sensors ?? please any help as was racing sunday!!!!! thanks mike

 

is there a live feed to centre wire on coil pack? have you checked for spark? is fuel pump running?

 

no spark at plugs, fuel pump running will check wether theres power to coil, thanks

 

If you're STAT SYNC is not changing to 'ON' under cranking - it won't run!

Are you seeing a viable RPM when cranking?

 

check that the ecu is getting a good voltage! this ecu is really fussy about its power supply if its under a certain voltage they dont want to know. sound like its the problem as you have touched the alternator. had the same problem with mine and it was the power cable was the wrong thickness loosing power when i relocated my battery to the boot. not sure what the minimum voltage should be as im not up with electrics sorry

 

what flywheel you running?

 

does the ECU have a relevant base map on it?

 

running a ap flywheel with trigger wheel on front pulley ecu has a good base map in , got car running eventually after a tow start cant understand why it wouldnt start on key as was cranking at approx 250rpm? im sure ive got a power drain some where as it seems to eat batterys not sure wether its me dodgy alterantor wiring or what

- did go racing in the end (first race the timing pin bolt in block fell out an pissed oil all over the exhasut)- looked like it was on fire -gave the marshalls some excercise! any advice on possiable power drain problems appreciated.. thanks again mike.

 

maybe not be a power drain but maybe the alternator isnt re-chaging the battery

id check that mate

 

whats the best way to check alternator is charging? seems to as puts 14 volts back into battery when running and battery voltage is about 12.5 when stationary.

 

Put a volt meter across the battery to check it but those values are ok.

 

is the battery big enough for the job in hand

 

yer i thought the readings where ok, battery is a big transit sized one so would of thought more than big enough , must be a power drain some where but cant find it?! thanks mike

 

How much current is being drawn when the car is sat idle without being switched on? Have you checked parasitic drain yet?
