Help. Not so common starting problem.

[jaybee747]

Hi all.

Running the car yesterday, I pulled into a side street to put roof on, as it was starting to rain.
On setting off again, the car stalled as if it was out of fuel. having no tools with me at the time, I could still check the basics.
I had a spark at the coil, and at the plug lead ends. The fuel pump was priming as normal. I checked the fuel rail at the valve for fuel, all OK. 10 mile previous I fueled up anyway.
So, I have ignition, fuel, albeit in the rail. If I am correct, the immobiliser doesn`t control the injectors, so I can eliminate that. What other options to check have I got?
I have another Chimaera so can borrow things, although I don`t want to. would a 400 ECU run a 450? this would eliminate the ECU not operating injectors wouldn`t it.
Any help would be greatly appreciated.

Also, no, I didn`t put any other fuel in. just the usual that i`ve used for years.

The other ecu would be good for seeing if it starts or not, probably run ok at a gentle pace, I ran mine from a standard LR one and it stated and ticked over just fine
