Its a DIS system operates with wasted spark on two positively switched coils
httpwww.fiatforum.comshowpost.ph...&postcount135 You need to wire to either coil. The rev counter needs to be set at though it were a 2 cylinder engine because each coil fires two cylinders.
yes i know malin dixon thankyou. ive read your thread quet a bit and i was jsut wodnering because ive found a company based in england somewhere that manufacture rev counters that have a switch on them to operate at twin coil function. the description says becuase of modern DIS ignition systems the 2 cylinder function is incorperated. so should work. gunna get onto the phone to them tomorrow probably and get one oredered.

D. Crank sensor Why would that cause an instantaneous ignition failure And no Im not trying to sound like a smartass Im genuinely non-plussed. Thanks.
Well I think the LT outputs come directly from the ECU and are not fused directly. Of course some parts of the ECU supply are fused but if you have checked those and they are all ok then dont worry about them......have you checked all the maxi fuse in the engine bay Think the Cinq has them as well I doubt your ECU has gone and died so there must be some other fault that is causing the ignition failure

Signal from crank sensor informs when the ECU should send neg pulse to coil (thus firing plugs) so no crank signal no spark.
Sounds like a cracked ignition coil Seis and Chinqs are renowned for it
Hi again i removed & tested the twin coil units (marked BAE 800) & one of them was open circuit on the secondary winding the other unit showed a resistance of 3.68M ohm.. now then the unit i got as a replacement is marked BAE 800B and has secondary resistance of only 7.23K ohm both have a primary value of 0.7ohm & are marked 12v.. Ive no idea what the correct values ought to be but considering the
Might be possible to fool the MPI ECU into doing ignition only if you can devise some means of supplying the right signal from the other sensors. But I doubt it would be worth the pain -- youll likely need a different ignition map and either Canems ignition only system or Megajolt should do the job better. For the MPI -- which ECU The 2 plug micro ECU is a PITA and Im not sure it can be reprogrammed.
if your fan never runs with ignition off then you can check by turning the ignition back on and waiting a minute. when the fan runs with the engine off there is little thermo syphon so the system may still boil if the coolant in the head gets too hot running the heater fan with the heater on hot may be as good or better. As cc1 suggests the fans can die of old age the red light comes on very late in
although i never discourage servicing your cooling system - your car has never thrown the temperature light so why are you worried exactly
Originally Posted by blu73 although i never discourage servicing your cooling system - your car has never thrown the temperature light so why are you worried exactly Simply because the fan is noticeably running more than it used to. Anyway I did what should have been my first port of call and checked the coolant - it was flushed and (supposedly) refilled at the service 2 months ago assuming it was done correctly then it has since lost 2L. No obvious leaks so where can that have gone
I dont know the Cinq at all but are you sure the red light is engine management Not brakes - low fluid Not ignition - no charge from alternator Have a look in the book if youre lucky enough to have it just to be sure. Regards John H

thatd be oil pressure switch cable. I bet your oil light doesnt come on when u turn the ignition on.
Hi. The light comes on when i turn the ignition but then goes out. Then when i start the engine it sometimes comes on a few seconds after i start it from cold sometimes it fine and doesnt come on at all. Same when starting from hot. Like today. It started fine from cold. Then i ran it about 5 miles and all was fine. I pulled over and started the engine again and all was fine..then a few miles later
rev counters will work on just about any spark ignition engine. The biggest issues are finding the coil wire and setting the rev counter to the correct number of cylinders which is the number the coil supplies not the total for the car. It is not very neat to take a signal from the coil. It is neater to take a signal from the ECU which uses the crankshaft sensor to know the revs. This is what fiat
you on the cheapestbest way to get my ignition system back together. Ive got a mechanic whos willing to fit the parts but I want to make sure I buy the correct ones. Would a chipped lockset etc with ecu from a 1996 n reg. 900cc Cinq work in a 1998 rreg 1108cc Cinq Sporting Theres a bit more information on this thread about it all. Any advice you could give me would be really appreciated httpwww.fiatforum.comcinquecento-seicento36576-stolen-cinq-repair-advice.html
I dont know how you are going to drive the distributor. Are you going to stick it on the end of the camshaft As far as I know all the fiat cinquecentos have two double-ended coils to avoid the need for a distributor. Just about all car ignition systems have one low tension connection of the coil joined to 12V (via the ignition switch). The other low tension connection of the coil is grounded and when
