Try cleaning fuse #6.

It could be as simple as a corroded fuse connection.

Hope this helps

First, the easiest thing to check is whether it's the short hose in the fuel tank (between the transfer pump and the metal line) -- just put enough gas in your tank to be sure it's at least half full (which submerges the hose). If it cures the problem, then that hose is the cause.

Second, to test the transfer pump (the proper name for the in-tank pump), you can measure the amperage of the current through it. If it's bad, it won't have the correct current. Hook up a VOM to the connection to the pump at the relay.

Frankly, though, it sounds more like a problem nearer the engine (feathering the pedal generally doesn't help a problem farther back) such as your AMM, your throttle body, or even your plugs and their wires.

I don't suspect the in-tank pump exactly from those symptoms though it could also be bad.

There could well be a hole in the short fuel hoses in the in-tank sending unit. This would cut some flow to the main pump. With a bad in-tank you'll noticeably hear the main pump complain. I say it goes MMMWWAARRRWWWWRRMMMMMMWWAARRRR. :)

I'd go after ignition components first. This literally happened to me this week with my wife's 90 745T. The spark plugs were shot. The wires were iffy and had a couple of abraded spots. And the dist cap and rotor showed a bit of oil intrusion and the rotor had burning on the tip.

The end result was that the car would barely start and move into the driveway on a wet day. New plugs got it running almost normally again, and a new cap and rotor helped the rest of the way.

Good luck,
