A weak crank signal would not cause this. We need to start with checking for codes as if you have an injector that is not firing then I suspect we have codes that will point us in the correct direction.

This could be a control module or a wiring issue but did you test the injector as shown in the guide below?

Let's start with checking for codes and we can go from there. Thanks

My mechanic has just scanned the car now, these are the results:

Injector circuit open - cylinder 1

Leak detect pump solenoid circuit

02 censor circuit - no activity detected - bank 1 sensor 2

Manifold absolute pressure/ barometric pressure circuit: high

Sounds like we have some wiring issues assuming all these are related. However, did they give you the actual codes so I can look them up? Unfortunately they don't list the codes by description. Thanks
