I am trying to remove the fuel pump/FI relay. I cannot figure out how to get a relay off the board. For the relays in front, I can see the tiny black clips front/back of the fuse (and even can't make THESE work as a test...no matter, because I can't see or feel these little clips at the base of the Fuel Pump relay!)

I have yanked enough on the darn thing I may have caused more damage to the circuits than I was looking for to begin with. Nothing in the FAQ talks about actually removing the relays...

Any tips appreciated.

There is no clip: just rock it very slightly and pull up. Have you removed the storage box above the relay tray for good access? Otherwise it is quite impossible.

Yup, I have taken out the storage box. I guess I will just be a bit more persistent.

At the fore and aft of each rectangular opening, flush with the tray, there are small "claw" type clips. I guess these are just self-activating when the relay is pushed in. You can see them on the drawing in the FAQ.

When you pull back on one with the edge of your fingernail, you can feel the one in back snugging it. Anyway, I guess these are not meant to be released manually.

Thanks Steve for your help. I'll keep at it.

Enough rocking back and forth and she came out.

For those of you who have 10 year old relays and pull them out expecting some sort of mess...I guess these things either look really bad, due to arcing caused by some malfunctioning accessory down the circuit, or, they look like mine...as if they had just come out of the factory, with all parts literally gleaming under their snap-cover.

I inspected all the solder connections on the back of the board, nothing awry. Just to be sure, got out the multimeter and checked continuity while operating the spring-contacts by hand. A-OK.

What I can't figure out is, if the relay and the fuse are fine (I checked the fuse for continuity too), then why has the main pump stopped making its trademark "bzzzt" when I turn the key to On?

WELL...maybe, as has been theorized elsewhere...maybe this is a sign of main pump failure (without total failure. I drive the car around just fine, once it starts.)

Remember, you have 2 pumps. So the other might be able to flow enough fuel to keep the car running once it has built up enough pressure to start. Have you checked the pump pressures and flow rates?

Bob,

Checking pressures/flow rates may be next. I think I will ask a service tech to do that; I'm not equipped!

Turns out I'm a one-pump (Regina) kinda guy. Maybe the pump is operating sub-par; not well enough to supply constant line pressure?

Where is the check valve? Can only find what appears to be a small pressure-check fitting, unless that's really the check valve I'm looking at (appears to be like a rifle casing, brass, stuck in "T" formation in the rubber fuel line. About a foot aft of the fuel filter.

Relay operates properly, but I'm not here the "bzzt" I used to hear. Fuel pressure regulator can't be too bad, the car restarts fine all day long.

I'm stumped. Maybe the in-tank connection hose from pump to fuel line is lousy, and releases line back-pressure.
