General uno problems

[unoturbo1]

hi there i have an uno turbo mk2 which will not start.i know a lot about fiats but the problem i am having is bugging me. my uno will not start at all fuel pump works but not when u turn the key. put a new pump relay in. i had it working for a bit but when i drove it it badly over fueled at kepted on cutting out and the rev counter didnt work and since then its not started again and will not start. but i think it might be my alarm which is a clifford.

does anyone know what can be done about these problems let me know

I think you have to take a systematic approach here...
Start by disabling/bypassing the alarm.

Over-fuelling - AFM, possibly, or coolant temp sensor - but rev counter not working? That sounds odd. Other gauges working OK?

You now need to check for a spark - perhaps the ignition ECU (the one with the green label and the vacuum pipe going in) has lost its supply. I think there are fuses attached to the top side of the fusebox. The rev counter gets its signal from the ECU, so it suggests that (unless the instruments have failed) there is now no chance of sparks. Hopefully this will be because of your alarm immobiliser...
