95 xj6 , have electrical power starter does not work.
95 xj6 i have complete power to all gauges and assy, i turn the key to start but there is no power activating the starter. I opened the hood and the starter connector behind the head only has power for a split second when i try to start the car , then power is lost. All power to the fuse boxes is working, I have power under the engine compt to all fuse boxes, and even power to the starter from the firewall but the ignition when turned will not make the car crank . It seems as if the alarm has made the starter motor not work, i do not have a remote , i have locked and unlocked the car several times but still no change, i am also getting power to the fuse box in the trunk for all circuts, please help or call i will compensate for your time 423-260-5985 Jim.

On most car batery"s there is corrosion, on Jaguar,you don't see it. Take off neg- post cable first than pos, and clean posts and cables with a battery. post cleaner. kgb

Do the gauges and warning lights work with key on? If not, check fusible links, AM1 for ignition key power. If the gauges/warning lights work, the key switch has power, so you can follow it to the starter solenoid. The start wire out of the ignition switch is a black/white wire, this is the hot wire to the solenoid, and only has power when key is held in start. With automatics, there is only one switch-a neutral start switch- between the ignition switch and the solenoid on the starter .
With a manual transmission, the black-white start wire goes to both a starter relay and a clutch start switch (on the clutch pedal), those two work together to send the power on to the starter solenoid. So, no crank, good battery, power to key, follow the black/white wire, the start relay and the clutch switch, to the starter solenoid- a hot wire there turns the starter motor on.
Start at the battery. Check for clean, tight connections. Any chance it is discharged? It needs to be at lest 12.6 volts on a voltmeter to be ready to start the car. Is there power from battery to the ignition switch? Turn key on. Do warning lights and gauges come on? And accessories work? Then there is power to the switch. If nothing, start checking fuses and fusible links that pass power from battery to the switch. An electrical circuit is a complete electrical path from a power source to an electrical load to ground, and back to the power source-the battery. The starting circuit is just such a circuit. From the battery to the key switch to a relay or switch (neutral safety switch) or two, to the starter, and then to ground-back to the battery. If the key turns power on, one could next see if power is getting to the starter solenoid, mounted on the starter. The small wire to the solenoid should have power to it when the key is held in crank position. Use a test light or voltmeter to check for power there. If has power, likely the starter or solenoid is bad. You then need to take it off and have it tested-a free service at most parts stores. If no power is getting to the solenoid, but the ignition switch has power, further testing of the start circuit will have to be done -the clutch switch (or neutral/park switch if automatic trans.), the starter relay, and whatever else is in your starting circuit. If car has an alarm system, make sure it is not activated, so the immobilizer function is not causing a no start. Good luck. Post back with results.
there are 2 connections on the bulkhead/firewall.
There is one on each side.The connectors are brass and the insulators
are plastic with a rubber boot. unless these connections are clean you may get all sorts of malfunctions
with switches,lights and electric
motors. Symptoms are similar to a
failing battery, something to start with..
get the oil pressure checked with a master gauge at a garage if ok will be oil gauge sender unit at fault if low with master gauge check oil pressure relief valve on filter housing i assume you have checked oil level
