New owner with an ecu problem

[bigB]

Is the 7.5 Amp starter signal fuse ok?

[Rayburn]

Still no progress. I have checked the fuses and checked the supply and earths on the ecu connectors - all appear good. The starter signal fuse looks good (though oddly the starter still works with it removed?). The engine doesn't fire even with the fuel pump running via a jump wire. Not sure what to check next. Any suggestions?

hi tom
so are you saying the car cranks fine but you have no spark and no fuel pump prime ?
if so what immobilizer is on it
is this the blue one that was on ebay

Hi mikei
Yes it cranks ok but doesn't start even with the fuel pump running - I haven't directly checked for a spark yet.

It is a Selca immobiliser (3.22?) that appears to act on the gauges and starter circuits (I get no dash lights or starter when it is set). Both circuits work when it is off.

Yes it is the blue one that was on ebay.

stick to the basics make sure you have a spark first
I may be wrong but that may have been owned by beatproducts on here some time ago
he may know more about the immobiliser
or you could just have no spark

Thanks for your continuing help.

I have done some more checks. It has a spark and a healthy 5v reference voltage at the engine sensors so the ecu is doing something. It should work with the fuel pump running - but doesn't!

I have decided that it is worth ruling out an ecu issue so I have sent it off to be tested.
