99 XP XLT PUMP NOT PRIMING?
Where is the best position to hear the fuel pump run for two seconds at intitial KEY-ON?
I live where there is highway noise, I'm trying to check if the pump is priming.
Thanks much.

Tried it a couple of times with a helper to switch the car on. I also went under the vehicle next to the tank and tried the same test. Could not hear anything 'buzzing' which is what I expect to hear since that's what I hear on my other vehicle when I do the same test.
Did the test several times, replacing relay 301 and 304 with my two known good/working 'FORD' relays of the same part#/type.
What I hear on the 99 XP about three seconds on is a clicks down in the fuel tank area (could not tell if switching on or off). Could it be the click is the end of the prime and in fact the fuel pump is priming rather quietly?
Can anybody with 99 XLT please do the same 'priming' test and reply back what you hear and where to best hear it?
Thanks.

You should be able to hear it fairly easy. From the sounds of it, you either are not getting power to the fuel pump, or the fuel pump is no good.
Did you check to see if power is getting to the fuel pump relay socket?

Also, on our 98 Volvo V70 with original pump, the priming can be hardly heard, while my other 98 Volvo S70 T5 with Walbro, the noise is unmistakable.
So please, anybody with Gen1 XP, let me know what noise to expect please? I hate to replace the pump only to find it's not the issue.
Thanks.

Funny, I thought that's what I've been doing. Obviously you're waiting for someone to just tell you what you want to hear instead of telling you what is what. I'm done, anyone else, anyone?

You should be able to hear a couple of noises including the pump prime sound...
My 98 definitely procures a "whine" sound when the key is turned.. Its faint but you can hear it...

There are two reasons I was insistent. 1) my place is really noisy because of my closeness to an interstate highway. 2) as I mentioned, I realized not all pumps are created equal - one of my Volvos made louder pump noise than the other, so much so that the other can hardly be heard unless you listened to it on the right spot.
My apologies if it sounded like you're input was taken lightly, please don't take it personally.
Thanks again.
