hey guys im at a stand still on my xjr. i dont get this car out on the road much and its stored in my underground parking stall..... havent tried to start this since december (my bad) but she wont start... heres the facts:

battery completly dead would not start on a boost so i replaced the battery... ive got no fuel pressure at the rail and fuel pump is not running (as far as i can tell)... all fuses fuel related are fine only getting p1111 on the scanner... fuel relay in the trunk clicks on and sends power to my fuel pump fuse for 2 seconds then clicks off... but i dont hear the pump run. car has less than 20k on it... and it ran fine last time i had it out. im wondering if there is some sort of fuel cut off security thing going on...... oh yeah and i have also verified the inertia cut off switch is not tripped.....

any help would be awsome im a cadillac guy i dont know these cars at all

 

"getting p1111 on the scanner" Forget that one, it simply means the OBDII drive test cycle has not completed. You got that after a reset.
There is a thread here somewhere about no start after sitting up that looked like fuel pumps. And I believe I read that they have some sort of known corrosion problem. If you got power to the pumps at the connector onm top of the tank, and no pressure, then either your pumps are crapped or you have some in tank problem. Its not the worst repair to remove and rplace the tank, buit its a PITA in my opinion.

 

I think this will pretty much cover the issue start to finish:

thanks for this link, im just thinking that withless than 20k on it my pump shouldnt be bad.. guess anything is possible though. the car is in my underground parking with a full tank of fuel so it makes it a bit more diffucult to pull that tank but i guess im not left with any other options.

i just wanted to verify that there wassnt some sort of fuel immobilization switch linked to the security system or somthing crazy like that.

 

No, your options are not good, I think you should sell it to me.

Just kidding, but I'm sure many on here would love to own that car... With those low miles, it must be a beauty. Good luck diagnosing.

 

the car is for sale. what do you guys think somthing like that would go for? 19511mi. i realize i will never recoup my 63k i paid for the ol girl but........ just looking for somthing reasonable to post the ad for... \

so im working on this issue right now trying to get the tank out but im having some problems damn thing is in there tight... ive manually operated the pump relay and i get power at the pump but she wont spin...

 

so i got the tank out.
took 15 stitches on that sharp edge where the tank halves come together trying to reach behind to disco those fuel lines... (seriously). doctor called it a rather extensive laceration........
anyways got the pumps out... yes plural.... put 12v to them one of them does nothing the other buzzes but it heats up real bad cant tell if its running or not but im going to go with not running.
damaged the return line but thats what i get for not towing it to my shop and tackling it in my parkade...
this car is very for sale.. i think you boys are crazy if this was one of my cadis it would be running with a cressent wrench and a hammer haha. but i apreciat all the help.

 

I'd like to say your Cadillac joke left me in stitches, but this is not the time...glad you got yhe Jag sorted out, though.

 

ok finally drove that ----- today but now no radio and no back up sensors i figure it may have to do with the wires i disconected to get that tank out...... any sugestions?

ps. i love you guys but these cars are rediculous

 

Hang on mate, if your going to bust on the cars you have to spell the insults correctly.

The backup sensors I can't answer without looking at a schematic, I don't have enough personal experience to troubleshoot off the cuff. First obvious point would be to check all the fuses.

Is the radio not powering up at all, or you just don't have any reception? Did you try casette or CD operation?

 

Trunk fuse box, #3, 5 amp. That feeds the radio chassis and the reverse park aid module. If it blows again, look at the two connector plugs at the reverse aid module, left rear of the trunk: maybe you jacked something up when you were disconnecting the wiring for the left rear sidemarker light.

You might also want to look at the wiring harness where it runs vertically up along the right end of the tank: you might have pinched a wire there and shorted that circuit to ground (white wire), if you still had the battery connected when you pulled the tank out.

 

sorry about the spelling haha got home drunk last night and thought i would post an update ill check all the obvious stuff that might have gone wrong tonight and get back with an update... to be honest and i am embarased but i did cut the black and red wires that go through the floor of the trunk to the park aid figured i would just spliced them at the end of the job... cant recall if the battery was on or off so maybe i just popped a fuse........ and jagtech thanks for your help even as im dissin these cars haha you the man

 

Glad to help, let me know if you're still hung up. Hung over I can't help with.

 

alright so i figured out the parkaid/radio problem.... turns out while bouncing some relays around in the trunk i neglected to replace the relay that feeds fuses 3,4,5 i think it was. but hey it was a really easy fix haha........ so jag tech one more for you.... lets say ive entered my radio code wrong 4 or 5 times (my bad) now its saying please wait for the last week (ive been waiting) is there anything i can do i do have the proper code now but........ i hate the dealer

 

Radio's hung over. Can't help with that one, either.

 

dealer then?

 

Try a raw egg, or wait and see if anyone else reading this knows the answer.

 

Do you happen to have the original owner's manuals? Most of my new cars have come with the code either on a card in the glove box, or printed somewhere in the manuals. If not, then I believe it's a trip to the dealer to prove ownership and retrieve the code.

 

Cheers, Sporty

This might also be a good time to start a new thread with the specific question as the topic. This one has has a long and winding road, yes?
