Friends, I'm in a sticky situation in that I'm moving accross town today and tomorrow and hoping to take my semi-derelict 1992 Loyale with me under it's own power. I still have dreams of fixing this car up, but I'd hate to have to tow it.

 

It was starting and running a month ago, but has developed a non-start problem that I've pretty much diagnosed to be a supply fuel pump problem. Engine is not getting fuel and I can't hear the supply pump when the ignition switch turns to run. Usually, I hear a low electrical hum as it pressurizes the tank.

 

I actualyl replaced one of these not too long ago (2-3 years), so I'm taking an educated guess that it's a fuel pump relay or solenoid as opposed to the pump itself. Since I'm frantically packing boxes, I don't have time for a more complete diagnosis. Unfortunately, my John Muir manual is packed in a box somewhere and I have no idea of how to find the relay. Can anybody offer me a tip for how to find it?

 

Thanks,

 

Jesse

I believe the relay is under the dash near the steering column. Sorry I can't be more specific.

Check the similar threads at the bottom of the page here. They will help you find the info you need. I replaced one myself earlier this year. It should be above the ecu along with the ignition relay.

Thanks to both of you--the other threads to explain it pretty well.

 

I'm hoping I'll have time to do the fuel pump test...

 

Regards,

Under the hood, connect the single-pole green connectors near the wiper motor. Then turn the key to On (don't crank it). The fuel pump should pulse with the clicking solenoids under the hood. Go back and tap it if it doesn't.

 

You can also unplug the harness and check for voltage while it's pulsing. This will narrow down to either a bad pump, or bad relay.

That's how I checked it. Then you're not wasting money on a fuel pump if you don't need it.

there is a blue and a brown relay side by side under the dash. i'm 90% sure that the blue relay is your fuel pump. I was fooling with mine a year ago, and time has its affects on my memory ....
