Moved post to Technical area where you may get a better response

Have you tried the cam position sensor as if its getting spark but not even firing on easy start then it has to be a timing issue so the sensor would be my first port of call

is that the crank shaft sensor

If it's been wet just try WD40 in all the relevant sensors. Water in them (from floods maybe?) screws the readings. The ECT sensor - next to the top hose - effectively controls the "choke" - water in there says "engine hot" and no "choke" is applied - crank it for ever.

even reverted to leaving leads plugs and ecu system in the house wrapped in a towel near the radiators. the immobilser n alarm light isnt on wen i unlock the car so i rule that out. cleaned the crank sensor. could it be the injectors or timing then. also i did have a coolant leak b4 xmas causing overheating but its a new head n was just an airlock i sorted

Fault code readers being sufficiently cheap these days, and the potential time saving in being able to see what the ECU is getting from sensors etc can be huge, perhaps it's time you added one to your toolkit - MEMS3 (the version of ECU in your MY2000 car) monitors and fault logs most of the possible issues the engine can suffer, sometimes needs a bit of lateral thinking as to what an underlying cause could be but on the whole they're money well spent. Especially when you've already ruled out most of the likely culprits...

I brought this obd2 reader off eBay for my X reg 2000 MGF. Works perfectly and has saved me loads of money diagnosing a fault with mine.

Mark my X reg is a 2000 model and is obd2. As long it is Obd2 compatible it doesn't matter that it says 2001 onwards. On MGF's its from a certain VIN in 2000. Have you checked to see if yours is obd2? The 2001 date is when it was made compulsory for all petrol cars to be obd2 compatible.

how do i find out if it obd2

Post by **Mykel** » Wed Jan 09, 2013 11:56 am

OBD2 works from VIN 522572 onwards.

VIN n° is on the dashboard next to windscreen, under bonnet on o/s inner wing near horns and in your Registration Document.
