1997 xk8 convertible no start issues cam and crank sensor codes
hey i have a 1997 jaguar xk8 convertible, i have a issue with it not starting have code p1336 for cam sensor and code for crankshaft sensor.. i replaced crankshaft sensor today and still same thing i will be ordering new cam shaft sensor in the morning, it just kills me to see this beautiful car sit. i have a few cars so its not my daily driver but if i can get it going like it was 3 weeks ago i rather be driving my cat then my svt cobra.. pls any help would be appreciated..
p.s. i did have a water leak in my ecu previously to this and replaced the ecu all connections look fine leading to ecu tcm and transmission harness i spent about 9 hours at my shop today tracking down all the wiring to make sure it wasnt a wiring issue.. even tried putting oil down the cylinders to see if it wash a cylinder wash issue but i havent had any luck on my own so i am seeking any knowledge from anyone that can help.
thanks

yea i work on cars for a living and own my own shop.. but when it comes to the cat shes had me stumpped more times than once.lol.. it hasnt started since i put the new ecu in. i started it 3 weeks ago to put it in my impound yard so it wasnt just sitting out in the open and when i went back to it last week battery still held 12 volts turned key to let the system analysis and got a engine fault/ transmission fault took the key out took the 4 bolts off the top of ecu and tcm box took ecu out and a good amount of water came out of ecu come to find out the hose was off to the drain for front windshield, which is the only way i can think that this much water got into the ecu in the 1st place.
i have fuel... havent checked for spark which i should have when i pulled coil packs just put in brand new bosch iridum plugs today. i have a whole xk8 coupe parts car i bought last year because my transmission went bad.
thank you for your time as well

It may be the battery. If it reads less than 12.4 that may be a problem, and if it gets much under 11 while cranking the ECM will not allow power to the coils.
Changing out the ECM for an exact match, including the /xxx code ie LJA1410 AK/010 might work, but still may require a refresh from factory software.

Another thought. You might want to send your original ECM to ASI and have them test it for $55 or so. Those early ECM's are worth several hundred and shouldn't just be thrown away.
