Clio 172 cup, not firing, have spark,low voltage to injectors ???

[clio_sport_172]

Recently bought a 172 cup and have had problems, I have had someone out and he said there is low voltage t the injectors. Therefore the injectors aren't opening and car not starting. What could the low voltages be??? Relays, earth, ecu, wiring ??? Any help would be appreciated, thanks.

Is the low voltage (what ever that actual reading is) specific/contained only to the injector(s) circuit or is it across the entire engine sensor array?

The bloke tested the sensors around the injectors, he took the inlet off and squired fuel down and it started momentarily, appreciate the help.

Also the electrical fault light is showing on the dash...

Right, in that case get it plugged in.

Guessing is unlikely to nail the issue straight away I'm afraid though at this point i suspect either a fuse, mcr or wiring fault.

Bump...
not sure what I'm looking for in regards to the main control relay. Turns over fine, I have sparks, starts when I put fuel directly in to inlet... Electrical fault somewhere??? Help
