My son had my wife's S at college, and the car stalled, giving a fuel pump code of some sort, and not only doesn't start, but won't crank. He said he went to check the battery and the stowage compartment was filled with rainwater about 3 inches deep, so we believe while driving the water splashed over the fuse panel next to the battery shutting it down. No blown fuses, and when I jump the solenoid with the key on it starts and stalls like a lack of fuel.
Why doesn't it crank without having to jump the solenoid? Could the water have fried the computer? Any suggestions while it's drying out?

 

Um, water and electronics don't mix - there are many unfortunate scenarios here - best bet - allow everything to dry and figure out where the rain water is getting into the wheel well. (search the forum on water ingress) check the trunk seal as a starting point.

Good Luck!

 

The spare tire compartment has now dried out for over a week, and the engine will not crank with the key. If I jump the solenoid, (with key in on position), the car will turn over, try to kick off, but not start. Any suggestions?

 

Something may be permantly damaged and needs replaced.

The PATS system will prevent cranking too. What is the anti-theft red light doing? Do you know where that is?

hey Dan Boyle, I have the same problem with my 2001 s-type v-8 mine floods and when my vehicle would not start I checked my fuses again and the fuel pump fuse had blown it in the luggage compartment (trunk) thats simple american talk. check it out again and by the way I have not figured out where the leaks comes from but i removed the drain plug kinda permanently so when it rains it drains. good luck

 

What is the PATS system? If you're referring to the red light on the middle of the top of the dash, it blinks like it always did.

 

Thanks for the tip, but if the fuel pump fuse would be blown, I don't think it would keep the car from cranking, only starting. I believe it could be something related to the security system, as the other gentleman suggests, but am open to all suggestions. Thanks! (I'm keeping the plug out too until it's home and in my garage).

 

When car is locked, it blinks every 2 seconds, when I put the key in the on position, it blinks rapidly. Is that bad or good?

 

Bad.
It should blink rapidly for one minute. Then blink a code after a pause can you check that. it will be 16, 17 or something like that so maybe rapid blinking - pause - one blink - pause six blinks.

 

Yes, bad. +1 on above.

 

You're right, after one minute the rapid flash stopped, them I got a single and then 6 multiple times, (assuming that means 16). What does that mean?
I checked all fuses. Is it possible the water could have caused a circuit breaker to fry, rather than the ECM? A tech at the Jaguar dealer said he's had this problem before, but it was never the ECM, however the things he told me to check were okay.

 

Norri, that's correct. After one minute of rapid blinks, it pauses, blinks once, and then 6 more times in multiples successions. Is that good or bad? Battery is fully charged, no blown fuses. Is it possible the water fried a breaker? A tech I spoke to at the Jag dealership said he encountered this before, but it was never the ECM. However, everything he suggested, I tried to no avail. Have you got a suggestion short of having it towed to the dealer$.

 

I have that as a (SCP / PWM / J1850) network fault, so could be a bad ground or the like in part of the OBD wiring. Probably between the PCM (or elsewhere) and PATS (key) transceiver. I'm not sure but that may be the wiring in/by the steering column.

I'm fairly sure that such a fault means the car will inhibit starting and you cannot bypass that. (So will need to find & fix the fault.)

I don't think any circuit breaker is fried. None is involved.

I think there's a PATS Diagnostic Flowchart in the TSBs (or somewhere). Looks like it might be a faulty power/ground on the PCM.

(PCM aka ECM)

The PCM itself is hardly ever faulty, so suspect it very last of all.

 

Try this, let us know how it goes thanks to Real_Tech if it works.

The diagnostic flow chart is in the pdf I posted yesterday.

 

The X200 is different from the X202 and the flowchart from 419-12 is not correct for this vehicle. I have posted a 'Picture' of the PATS page from my S-Type Advanced Diagnostics Training coarse.

Check the SCP network as JagV8 stated. The network has open/short problems. A module on the network might be water damaged.

Thanks all. I found it to be a bad ground on the fuse panel in the tire compartment.
