I have owned xjs in the past I know bought a 99 auto I keep getting codes for crank and cam positions sensors I have check connectors for both and replaced both and even the ecm still same starts runs like it's cammed timing is,on point checked with a,timing light and even pulles valve cover to check cam timing with valves my question is is the some one who has a working schematic for my 99

Can't set timing with a timing light. What was the exact number code that caused you to replace the PCM?

Xjlee

hi so,the,codes,were the two I cant,remember them but one was cam,sensor the other was crank sensor and I did not time it with the,light I checked it with light after I replaced both sensors I checked grounds and all the connectors cleaned,them tried again same thing them replaced ecm same codes now I am,thinking a,problem in harness.. p.s I put,crank on 0 Deg set dizzy to number one fires right off just runs lopes and runs rough good compression on all cyl all valves moving as should.

Did you check the harness at the rear of the engine for cuts/damage?
What's the fuel pressure in psi?

Xjlee

Yea I checked none the looms,look. Un shaved. And fuel psi was 30 40 ish

Turbo X_J

1999 should be 49.5, +/- 5 psi.

Xjlee

Well. Ok i,would like,to find a wiring diagram to check that as,well I am not sure,if ten psi would cause,those codes and issues.. the,tech go crazy as well
