UPDATE: fuel starvation/loud pump on 83 urq

[Brady Moffatt]

Hi All,

Well, no luck yet....

The car will not accelerate without stumbling badly. This can occur even in
1st gear. The tach needle doesn't bounce so I think the coil is working.
BTW, how hot is a coil supposed to get?

Here's what I've done so far:

I relayed the pump to direct battery power and gained over a volt (but I did
that a while ago).

I looked for clogged or bubbling pre-filter. Nope, don't even have one. It's
a piece of pipe. Which is clean and unclogged.

I let the fuel flow out of the tank outlet hose (pre-filter inlet) for a few
seconds. It flowed very well, no gurgling or bubbling, just a fast-moving
smooth stream of clean fuel.

I moved to the fuel filter and changed it. Brown gas came out of it. In the
drain pan, I could see some fine rust sediment. Great, I thought. Maybe this
is the problem. Nope, runs the same as before.

That leaves the accumulator and the pump.

The accumulator was replaced by a PO 4 years and not many miles ago. I have
the receipt.

Regardless of changes in pitch, the pump is much louder than it was and I
think it's original! Sigh. I have a spare used pump from my 4kq parts car.
I'll try that for troubleshooting purposes.

Any other ideas?

Thanks.

Cheers,
Brady
