my jaguar is having problems starting recently change the battery and still will not start . every thing in side the car is on radio,lights,ac,ect .can someone please help me out i'm stumped

 

It would be hard to give you any advice based on what you have given us. Does the starter turn? Any signs of trying to start? I assume this is an X-Type? Could be a fuel problem, could be an electrical problem.

 

What prompted the battery change? Are you sure the cables are snugged up on the terminals? No start = ? Doesn't turn over?

 

alright i was driving one day,the car was fine allday it showed no signs of giving up . so when i got back home and tried to leave again it would'nt crank, not a sound all lights was off. so i replaced the battery as soon as i hooked the new battery up everything came back on except the vehicle. i took the negative off for 10min. put it on nothing, i reset the button under the passenger seat that reset my factory alarm[no after market alarm installed] but still no crank, i put a jumper between pin 3 and 5 on relay the starter started to turn but didnt craank, i get 12.4 on fuse panels, i switched r9 with r10 same size just to troubleshoot 10 and 10 worked in r9 and r9 was working because r9 works the lights and they work, i checked all fuses 3 times both panels. i also tested the starter with a multimeter and got 12.4 but when my wife tried to crank while i tested it droped to 11.2 on the big cable on the starter so i came to the conclusion that it was the starter because i thought that the 12 had to be consistent on the starter in order for it to have the right amount of torque to start the car. if u have any suggestions, im i on the money, or should i have a scan done before i install the starter, i would hate to have to pay for a tow truck, so any info you give me i would deeply appreciate that.

 

I too assume you have an X-Type?? Can you confirm? X-Types are notorious for losing solid connection on the negative battery terminal cable. Follow it to its grounding point and make sure it is a good connection. 12.4 should run the starter with no problems given a good ground.

I have a used X-Type starter on my shelf. I'm not into selling parts here, but I haven't had a calling or need for it in months now, so if you decide it can help you, pm me.

 

Let me start by saying thanks for your help man i appreciate that. The 12.4 is active before i try to crank, as soon as i put it in position 3 it drops to 11.2, so i wondered if i had to have 12.4 on the stater from begining to end during the crank process

 

Yes, once you drop to 10/11 volts, you're not going to start. I forgot what you said about the condition of the battery, but if the connections and grounds are good, could be a dead or weak cell in the battery.

Jaguars, in general, need strong healthy batteries. A battery won't stretch in a modern Jaguar. I change batteries out for new in both my XK8 and X350 every 24/30 months. My X-Type too when I owned it.
