I bought this at auction but it seems to be fairly well maintained, how ever when i got the car it turned over but wouldn't start. I found the fuel pump frozen up & replaced it then when I jumpered the relay I had an injector with a bad lower oring and replaced it. now I have spark and fuel but no start very hot battery. any help or advice would be very appreciated

 

I would suggest you buy a code reader, even an inexpensive one should read engine codes. Then post the code numbers here and others will help.

I ordered a code reader but not here yet, but today I took plugs out and cleaned them and took compression test and checked pluge for fire everything is ok reinstalled everything and started the engine, ran about 10/15 secs and died like it ran out of gas I jumpered fuel pump relay with the same results
Where can I get error code definitions ?

 

As RJ237 says in #2, post the codes here and others will reply with the definitions.

Alternatively after 3 days forum membership and minimum 10 posts, you'll be able to download JTIS (Jaguar Technical Information System) from the FAQ's.

Step 1- squirt oil into spark plug holes and do a compression check

 

I did not squirt oil into pistons but compression was from 130 /145

 

Then it is not bent valves. Replace fuel filter (easy, should do it anyway) and check for fuel pump operation- Codes would definitely be helpful

 

I got an error code of p1336 crank/cam sensor & p1230 fuel pump relay but the relay I have had jumpered so that takes care of that. where is this sensor located and what does it look like

 

Hi
Here is a JPEG file of the 1998 XJ Electronic Engine Controls lists and shows each of 6 sensors (diagram with sensor image/location) in engine compartment (Look at listed item 3 - Crankshaft Position Sensor and item 6 - Camshaft Position Sensor):

i was wondering if the crank sensor can be reached without pulling the engine? is the cam sensor the black vacuum pot on the throttle assy?

 

Hi Roy
Sorry that I could not be more help, since our 2001 XJ8 has AJ27 engine and it is not the same as your 1998 XJ8 AJ26 engine.

I also found this diagram showing the Engine Harness connector on AJ26 engine.
Looks like the camshaft position sensor is bolted somewhere on or near the black pot that is attached to the Throttle Body.

See item listed as #15 (P1015 is the electrical wiring connector end of the camshaft position sensor).



I circled the whole length of the camshaft position sensor (from plug connector end to the bolt on end) in red on the diagram.


The crankshaft position sensor is not on this diagram.

Here is another JPEG taken from the JTIS21 Shop Repair Manual software (LH Cylinder Head R&I - step 12 shows crankshaft position sensor location & removal instructions):





Here is a JPEG file showing Photos of both of sensors (Ebay photos of Aftermarket parts):

Jim,

I had to add a post just to add a 'Thank You'. You are a treasure to this forum.

 

Agreed. Thanks Test!

 

I had to say thanks, this last jpeg with the sensor position was extremely helpful as I do have a 4 post lift It shouldn't be to hard. the engine does start and run (if you give a little throttle) for about 20 secs then dies not like you turn the key off but more like you run out of gas but i believe I still have good rail pressure. I am thinking like the computer is shutting the injector fire off. it acts the same way if i jumper the fuel relay.
