mk2 Posted July 20 Report Share Posted July 20 Definitely crank sensor? Quote Link to comment Share on other sites More sharing options...

peterstanding Posted July 20 Author Report Share Posted July 20 just spoke to a garage i have used for years and they said worst case could be snapped timing belt, reversed the car off the drive engine stopped, how likely is the cam belt could have snapped was done around 5 years ago and done 30000 miles since last change Quote Link to comment Share on other sites More sharing options...
mk2 Posted July 20 Report Share Posted July 20 Do you get ignition sparks? If yes, then it's not the crank sensor. Is it the imobiliser? You get fuel smell at the exhaust? Quote Link to comment Share on other sites More sharing options...

peterstanding Posted August 8 Author Report Share Posted August 8 getting no spark to coil pack changed coil pack but still no spark my 1.0 ALD engine has a 410 relay which appears to be for the fuel pump, is there any other relays that could be cutting power to the coil pack, when i changed the crank position sesnor it had also blown fuse 34 and 40 both changed and now dont blow, i get the pre prine when the door opens and spark plugs are wet with petrol, changed spark plugs as well but still cranks but wont start, any other suggestions?

mk2 Posted August 8 Report Share Posted August 8 When cranking does the rev counter move? If not, might be the crank sensor... Quote Link to comment Share on other sites More sharing options...
peterstanding Posted August 8 Author Report Share Posted August 8 yes the rpm needle does rise again after fitting the new crank sensor Quote Link to comment Share on other sites More sharing options...
peterstanding Posted August 8 Author Report Share Posted August 8 it didnt rise with the old failed crank sensor but it does rise again now the new one is fitted, which relay controls power to the coil? Quote Link to comment Share on other sites More sharing options...
peterstanding Posted August 17 Author Report Share Posted August 17 how is it possible to remove the 410 relay there is not enough room to get my hand in there so i can get it out and get a new one in Quote Link to comment Share on other sites More sharing options...
lupo 1.7sdi Posted August 17 Report Share Posted August 17 This engine does not have a relay that powers the ECU or the spark plugs. Only a relay that powers the fuel pump, injectors, lambda probe and the vapor canister valve. There are a few fuses that need to be checked: F2(80A), F3 (10A), F24(10A), F31(10A), F34(10A), F39/F40(25A). If the fuses are ok do the following operations/checks in the order listed below: - clean the spark plugs well - install them and turn on the ignition (without turning the starter) - remove the spark plugs and check if the spark plugs are dry or wet. If they are wet then I think the problem is with the ECU (it should not open the injectors without turning on the starter. When turning on the ignition it should only prime the supply circuit). There would also be the possibility (I don't know how plausible) that the injectors remained open - if you still have the spark plugs removed, connect their plugs and place them on the engine pressed with a piece of wood or something insulating so that the spark plug body makes contact with the engine body - have someone turn the starter and you check if the spark plugs spark - if they spark, install the spark plugs - if they don't spark, the induction coil is ok and the fuses are ok then possible causes would be: defective ECU or some broken wires (check especially the wires coming from the ECU to the induction coil - if the spark plugs spark, but after installation and trying to start they get wet with gasoline then most likely the timing is off and needs to be checked (in other words there is gasoline, there is spark, but it is not given at the right time). I hope it is useful to you this algorithm and tell us the results of the checks. Quote Link to comment Share on other sites More sharing options...
lupo 1.7sdi Posted August 17 Report Share Posted August 17 If you want to change the pump relay below you have some guidelines. You need a pdf reader. It is quite difficult, but not impossible. 3-Removing and installing fuse holder in front left footwell.pdf2-Removing and installing coupling station below relay carrier.pdf1-Removing and installing relay carrier.pdf Quote Link to comment Share on other sites More sharing options...
peterstanding Posted August 18 Author Report Share Posted August 18 which fuse is f2 80a? Quote Link to comment Share on other sites More sharing options...
lupo 1.7sdi Posted August 18 Report Share Posted August 18 (edited) There is a small box on the battery at the positive terminal. Under that cover are some fuses in the form of blades. Below you have all the fuses Fuse.pdf Edited August 18 by lupo 1.7sdi Quote Link to comment Share on other sites More sharing options...
peterstanding Posted August 18 Author Report Share Posted August 18 mine has sa1 and sa2 but where is the actual fuse? as it appears to be a nut and wire Quote Link to comment Share on other sites More sharing options...
lupo 1.7sdi Posted August 18 Report Share Posted August 18 The number of fuses depends on the model and features. I have circled the fuse in the picture. In the post above I added a document with all the fuses Fuse.pdf Quote Link to comment Share on other sites More sharing options...
mk2 Posted August 18 Report Share Posted August 18 Have you checked the ignition switch? Also, have you checked the engine bay voltages? Injector bus, ignition bus and sensors (unplugged). Quote Link to comment Share on other sites More sharing options...
