Any locals know xj electronics?

[BlackRock]

Looking for anyone in my area that I can pay to come by and help me through a electrical issue. I am in El Dorado Hills, CA (30 mins from Sacramento). Drove the 89' XJ into the garage, did a bunch of work to suspension, changed oil pan gasket and rear main seal, tranny pan, tranny cooler lines, motor mounts, etc. Went to start it after all work was complete, no start with no spark. What I have done: switched out multiple ignition/sensor parts from another running XJ. Replaced my CPS twice with the last being an OEM factory sensor, new distributer, cap, rotor, plugs, new battery, new water temperature sensor, new ignition switch, cleaned all connections, refreshed all ground, and more!

So when I turn the key on, no 4 second prime to fuel rail, when cranking I get appropriate fuel pressure but no spark. Also new, the water temperature gauge is now full right when cranking.

Will pay a mechanic to come by. I have all the tools you will need here.

Please lmk if you or if someone you know can help.

Thanks, Mark

it seems you already checked your grounds at the firewall and battery. thats good.

ignition coil, CPS , and grounds are my first suspects.Also new plugs and plug wires cant really hurt if they are old. Then check the wiring to them, check resistance for grounds possibly at CPS to see if its less than 1ohm. if you fried a CPS wire somehow that could do it.

the coolant temp gauge is at the back of the block, the coolant temp sensor is under the manifold on the driver side.

wire from coil to distributor as well.


melted CPS wires will do it.


did you knock off the knock sensor or 02 sensor when doing suspension work?

i don't know if the NSS would cause anything here, but have you tried it in N and in P?

also the TPS could be done. have you swapped in an old TPS?

you didn't change the timing chain or anything did you? could it be 180* off? did you pull the dizzy out?

what about the fuse panel inside or the relay block on the passenger side of the engine bay?

what about compression?
