I just got a 1989 XJS v12. This car has not been on the road since 2015. I have gone through all fluids and replaced. My problem is that I can not get it to start. Please know I will need step by steps. Never had one of these before.
I have new fuel pump and filter. Cleaned out tank and new fuel. Fuel getting to rail. Injectors click when throttle is opened. I have been reading the forum.
I disconnected the injectors and find power on both sides with key on. When cranking does not change. Power on both sides of connector. I removed the module on right side. Cigarette pack… Checked all connections and cleaned. Still same thing. I removed the ecu in the trunk and looked at the connectors. They are clean. Went ahead and found connector to front crank sensor, cleaned that and checked resistance. Seems good. Variation when cranking. So… I think that crank sensor is good. I have sprayed ether and it burped/ran for a few seconds. This tells me spark is good.
Can someone PLEASE point me in the right direction? Again… Like a two year old please.
I will be looking for the shielded wire next.
PLEASE HELP! This car is beautiful, but useless if it cant run…
Thank you in advance!
