I picked this car up "as is". The previous owner said the lower radiator hose popped off while on highway. It overheated and he pulled over. Car would not start after that.

I have fuel and spark. With a fully charged battery, it cranks kind of weak, but no start. I also read the following codes:P0430; P1603 x 2; P0158; P1000

Any suggestions? I am pretty decent mechanic, but this is my first Jaguar.

Thanks, Rob

 

The P1000 (Onboard Monitoring tests not completed since last memory clear) shows someone has already been trying to troubleshoot this.

The possible causes of the other DTC's are:




Battery disconnection could account for P1603 which leaves HO2 sensors as the likely culprit for the non-start.

I would still be concerned about possible damage caused by overheating even when you do get it started.

It is Ford engine and most likely Ford sensors. I would check compression, at least in easy to reach cylinders.
