Power on both sides of coil contionious no power to plugs won't start 91 xj6 fuel pump also not working unless use a jumperat fuel pump relay.

you will need to check the plug to the pump on top of the tank. check for voltage. then if no volts trace the wires back. also you should check the relay have some one at the relay listening to see if it clicks when you turn the key. no click no volts no volts may be a warn out relay, if it buzzes change it.

What was wrong in first place?why you change this that.battery,connection,fuel filter,fuel pump,check oil,

Thanks.

If the car will not crank then you have a battery, cable or starter issue. If the car will crank but not start then the problem may be the fuel pump relay. There should be an electrical diagram on the side of the relay. Apply 12v to either side of the coil and you should here a click. Then check for continuity between the other two terminals with voltage applied. If you have no continuity then the relay is bad.

Have you checked (or wired around) the fuel pump relay?

if your fuel pump and relay are new, how about your fuel filter, if your fuel pump is working but no fuel turns out, check fuel pump polarity, if ok, there will be a clogging in fuel lines, take a high pressure air and plug it to fuel outlet in fuel lines test port, allow air to go back up to fuel tank and observe if the air goes, if not, check or change fuel line, if the air goes to tank, direct your fuel relay pin 30 and 87 and check if the fuel runs to the injectors, if not, change a good fuel pump

The fuel pump relay is at fault. The engine will start running off the oil pressure sensor for the 3rd wire connected to the sensor feeds power to the fuel pump which makes your truck start right up. When the engine achomplish the standard oil pressure as needed the sensor shuts power off by the PCM default system and turns on the fuel pump relay to continue working the fuel pump. replace the relay and you will be driving around again

It's best to buy the subscription to your car here www.alldatdiy.com and read the information on that car, I only have down to 93 and don't know if they are the same. hope this helps.

Timing out ,check it on no1 cylinder at TDC then check distributor position ,the arm is pointing at no1 plug lead

Hi irvj6ohn:
The 1993 and 1994 XJ6 Fuel Pump Relay is located in the trunk of the vehicle on the right hand rear side. It is light blue and black in color.
I hope this helps.
