General Seicento 00 spi 1.1 pulsing code light and click fuel relay.

[Fiatcinquecento]

WONT START. the passenger light is alot weaker than the driver side, which my father said it was a bad earth.
I've cleaned the one going to the body by the battery tray. Cleaned the one going to the gearbox. Cleaned the ecu ground. Is there any other one hidden somewhere.
Need a bit of help. Code light also dosnt turn off, stays a solid colour, and in tandem the fuel relay pulses with it.

There is an earth behind each light cluster.

Does sound like a load of earth problems, add more earths. You can never have too many.

Thanks, I have also tried adding more with jump leads, which did not help. Mouse droppings all over engine bay along the loom leading into the dash. I'm currently taking dash out too ?

Ah looks your gonna have strip as much as you can and throrougly check all the wiring mouse droppings means it's likely they have been chewing the wires around the car causing all sorts of issues

Got back to the sei. Dash out and I inspected the wiring loom, all is A OK. It doesn't seem the mouse made it inside the car. As rallycinq said there is Earth's behind both lights and I took them off and cleaned them. Still no luck.

The car turns over but no go(which it has always done) . With the ignition on Mar, the code light stays on constantly, the oil and battery light too, no injector light.
The fuel pump is not priming. I also put one More earth from the front crash bar to the cam cover, and still the same results, a clicking fuel pump relay by the ecu.

I'm pretty stumped now
I have about 10 sei's as donors, so I am open to suggestions on what to change....

Got the sei fixed, a ground was literally unbolted from around the coilpacks. It seems to earth the alternator and starter wiring, and then leads to the ecu main harness.

Just for anyone with the same problem, it's easily missed ?

hi,I have the same problem,clicking fuel pump relay,and no turning over.


il have a look at the area you have sorted yours by cleaning and fixing earth to by coil pack.


thanks Jason wexford

My car wasn't turning over, till I took a hammer to the starter soleinoid!
