Hi ppl ! I have a Brava 1.4 on a u.k. x registraion (2000).
The car drives normaly , but on occasion will not re-start , I checked and there is no spark . Repeated attempts and the car starts . When the car is running the spark is very orange and weak. Could this be the car immobilising its self ? Not sure if it has an immob tho... Could it be the coil pack? The Crank angle sensor ? any suggestions???
 
The crankshaft position sensor = The Crank angle sensor as u named it , u need to change it !
 
When the car starts it never cut's out or misbehaves at all , would a faulty crank sensor stop the spark?
 
why dont you tell us what the problem was?

if it wasn't crank sensor then the next most likely cause of no sparks is an intermittent immob fault from the aerial on the ignition switch (cant read key so wiggle its wire and all is fixed). if that was the case then the key code light would remain lit when it refused to start. since you did not mention a key code light in your original post this possiblity was not suggested.

or was it something else?
 
Brava 1.4 Hot Starting Problems


Hi, well after a lot of time, effort and money spent on 'Betsie Brava' I've fixed the dreaded Hot-Starting problem. IT WAS THE FUEL INJECTOR.
Following the help and advice I received from members on this site I changed everything there was to change:
Crank position sensor, temperature sensor, oxygen sensor, ECU, ignition coil, fuel pump etc etc.

As a last resort and despite nobody ever having experienced injector problems I decided it was worth paying a last £45 for a replacement injector. The car now starts up every time, hot or cold. I started to think it might be the injector when I took the cover off to look inside, with the engine hot. It was a freezing cold day. Instead of needing an hour or more to cool down the engine fired up. I guessed that the injector was not working when it was hot. When the engine was running the cool air passing over it kept it cool enough to work. When the engine was turned off heat from the engine would rise up the throttle body and the injector would get hot. After being left for just a few minutes the injector was then hot enough to fail. It was then necessary to leave the engine to cool down completely before it would restart. It proved to be difficult tracking down an injector (I live in the Isle of Man) but eventually I found a breaker that did a complete throttle body for £45 delivered.

So, Betsie has been saved from the scrapyard. Many thanks to everyone who offered help. Hopefully my experience will help others who have had the same problems.
