Jaguar Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome to justanswer.com
That fault code P0193 is for the sensor reading high voltage/pressure which makes sense since it did go all the way up to 80 psi. The fuel pump is controlled by the driver module located under the driver rear seat cushion. The driver module receives the signal from the ECM and controls both the power and ground side. I do not think this is the cause of the crank no start since pressure was present. When the engine did not start was it cranking strong, did you have spark and did you try jumping or boosting the battery?
Yes I have run into this before but we did not discuss that P0335. See my post on another question from two years ago.
