[DML] Re: Fuel Pump Question/problem

["Steven G. Rogers" <steven.rogers@xxxx>]

First, can you start the car by spraying starter fluid into the intake (under the air filter?) while cranking?

If so, you have a problem getting fuel to the engine. It could be:
1. The fuel pump. Take the cover out of the wheel well and listen for it while someone tries to start the car.
If it sounds like it's working, then it might be the accumulator. It could also be broken fuel lines into or
out of the pump.
2. No sound from fuel pump. Take of the rubber cover over the pump. Are the wires rusted at the connection?
(oddly, the water drain for the windshield pours right onto this thing). If so, can you repair the wires? Check
for 12v with a meter. Could be bad fuel pump.
3. Emergency cut off switch, located behind the carpet near the clutch pedal. Black box with on/off pin.
Designed to shut the fuel pump off if you get hard enough to through the magnetic switch. These fail
pretty frequently (hey, they're old). You can try jumping it, but use similar guage wire, I found that trying to
jump it with a thin wire once and it didn't work, but a heavy guage wire did. PS: to work on it, you'll need to
unscrew it, keep the pin out, and then jump the wires (I can't remember the color combo, so use a meter
to check for 12v)
4. Idle control unit located where the fuses are. You can jump this, but frankly I can't remember how.
It's easiest to eliminate this by putting yours in another delorean (if you have one handy) and see if it
has the same effect.

Good luck - I replaced my fuel pump once, and it's not hard, but the hoses are old and not always
easy to find.

Subject:	[DML] Fuel Pump Question/problem

Hi, my 81 suffered from the no-hot-start problem since I received the
car about 4 months ago, other symptoms included: struggling when gas
was pushed down all the way before the car had ran for about 10 minutes,
and a long cranking was required to start the car, sometime it would
take up to 30 seconds. Now the car doesn't start at all (it tries, but
doesn't start) I thought it might be the accumulator, but now it seems
that no fuel reaches the engine at all. I don't remember 100% if the
fuel pump made a sound when the car was first turned on, but now it
doesn't for sure, there is no sound from up front at all. I already
checked all fuses (i heard that one controls the fuel pump right?) and
they are fine. So, it sounds to me like the pump went bad, is this the
correct assumption? I guess my real question is, do all of the symptoms
I listed above match those of a fuel pump that is going bad? Or is this
some kind of major problem?
Thanks a lot for taking the time to help me,
Michael Schaefer
