Ford Focus 2005 Wont Start At Times. Possible (Ecu)

[luv2vexx]

Hi guys.

I have a Ford Focus 1.6 Ghia, 62000 on the clock. 2005

It is a excellent drive and used to start up first time but unfortunately it has now become faulty.

Now the car drives all well for hours but when i do switch the engine off at times and come back to it the car doesn't start, it doesn't even crank. everything else works, like radio, electrics central locking etc. I called up a ford focus specialist of gumtree. he stated i needed a new ecu as there was a connection lost some where, he then said that i had a dry connection in the front fuse so he sprayed it with some sort of cleaner. the problem was still there. its very annoying, the car isn't showing a fault codes. your help is much appreciated.

you could have a loose earth cable somewhere that can cause this issue. do you have access to jump leads? if the car doesnt start but the radio comes on then use jump leads but connect the earth to a part of the engine and not the battery. if it starts first time you know you have a loose earth. even if the cable is just loose, it can cause problems.

if its not firing up I can see why he came to his conclusions, but there could be more and less to it.

When you try to start the car, does the red light on the instrument cluster blink like a loonatic?
