Subject: Re: Re Delorean went BOOM

Actually, this was technically a muffler explosion, not a backfire.
Backfires go backwards towards intake (flames out of carburetor),
muffler explosions go forward.

Am willing to bet timing is way off. Spark escaping through open
valves causes all kinds of problems. Can ignite fuel mixture towards
metering device or unburned in exhaust system

Unplug fuel pump and put a timing light on cylinder #1 while someone
cranks car (or run a wire from jump start post to starter solenoid).
Will be well retarded from 13 degrees, but should still be on scale.

If timing mark OK, pop passenger valve cover off. Is really quite easy
on that side. Watch intake valve and you will see TDC. Paint or
otherwise mark timing mark to distinguish and try timing light again.
That will tell you if 180 degrees off.

Doubt if you hurt engine itself. Like David T suggests, check exhaust
gaskets, O2 sensor, and perhaps honeycomb inside catalytic converter.
Check belts and radiator hoses for collateral damage.

That is a long way to move the fluid. I don't know if it would be a 
performance problem or not. The water pump handles the coolant 
movement over that distance but the auto trans has problems moving 
fluid through a cooler over that distance, especially through too 
small of a hose. Some sizing and measurement should probably be done 
to preclude mounting something that doesn't work.

Aaron,
I know an insane amount of time has passed since you posted this but the D
you saw was probably mine!!!
I purchased it from PJ Grady the day before 2/14/2002 (Valentines day). I
work at the old General Foods building in Rye Brook, you know... the
"Tajmahal". On Friday nights I always go up 120 to Manhatanville road's
connection to the 684 (because 287 is a parking lot) on my long trek to
Wappingers Falls. That's directly past the off ramp of the Hutch. I probably
had a big smile on my face.
I didn't have the vanity plates yet.
It had to have been me! Pretty cool!

Hi all,

  I spotted a Delorean on Friday night traveling on Purchase Street (Route

Anyone know an X-ref for the switch for the reverse lights?

Mine is busted; gives 1200 Ohms of resistance in the ON-position :-(

Or are they rebuildable? Doesn't look like it...

And an X-ref for the seals on the tranny for the Drive Shafts
would be nice too; If I had time I could order them in the US,
but the Thanny is on the workbench NOW and HAS to be off of
there within 2 days...

Thanks,

Subject: Help! My new DMC won't start

Hello,
I have just recently purchased a late 1983 DeLorean (20022). The car 
only has 4000 miles on it and it's beautiful!
The car seemed to run well after being driven for a few minutes, but 
the cold idle surges up and down and the car is VERY, VERY sluggish 
for the first few miles whenever I drive it.
Yesterday I was doing some detailing on the car, but when I tried to 
start it to put it back in the garage, it wouldn't start. It turns 
over fine, but just keeps cranking.
Any suggestions for me? I would appreciate any help, as the car is 
now stuck in my driveway.
Thank you
Jeff

Subject: RE: Help! My new DMC won't start

Jeff, Have you done a tune up on it and maybe replace the 02 sensor. Even
with low miles the parts are 20+ years old. The seeking is caused by the 02
sensor trying to adjust the air to fuel mixture. On the starting situating,
if you keep cranking on it and it doesn't start fast you may flood out
because of the cold start valve. If it's hot, then you may have the typical
hot start problem where the accumulator and o ring's need to be replaced. Is
the fuel pump running and it has sufficient fuel in it.

Generaly when the antennae gets stuck it is because the nylon drive
cable breaks. It is part of the mast assembly. It is the part that
pushes the mast up and down.  You might get lucky and find one
locally. They are supposed to be black but the chrome one is more
commonly available. If you are not very handy you can get the whole
power antennae.

Subject: RE: No power at 4000 RPM

I found this message draft that I was putting together after I had power
problems with my car December 2002.  The power would drop off above 4000
RPM.  I played around with shim thicknesses but I think that I may have just
flushed a piece of debris from the fuel system.  The car starts and runs
strong now and pulls up to redline.  Perhaps this Winter I will get a chance
to fool around with it some more.

Scott

Below is the test readings I took while trouble shooting.

The injectors are new and were installed during my major tune-up last spring
(2002).

I increased the shim thickness and the new readings are;
1.7 Control Cold 50 F
5.4 Primary
3.0 Rest

2.0 Control  Cold 70F ambient temperature
5.4 Primary  Cold
3.0 Rest     Cold

3.5 Control   Hot engine warmed up
5.4 Primary   Hot
3.2 Rest      Hot

Original Shim
2.0 Control
4.9 Primary
2.9 Rest

Timing
13_at_dml_Hot Idle
32_at_dml_4000 RPM Total

The car runs fine now.

I'm not sure if it was the increase in pressure or if I flushed some piece
of trash out to the distributor.

Scott, See below.
John Hervey

<< Recently I posted a message asking for ideas on what could be causing
the drop in power at full throttle once the engine started going past  4000
rpm.
  
 I installed a gauge to measure fuel system pressures.
  
 All reading were taken on a cold engine, 70 F ambient temperature. ( what 
are your readings hot.)
  
 Control Pressure = 2 bar
 Primary Pressure = 4.9 bar
 Rest Pressure = 2.9 bar
 Rest Pressure after 10 minutes = 2.5 bar
  
 Looking at my chart, it looks like primary pressure is at the bottom end
of the allowable checking pressure 4.9 to 5.5 bar.  I can set the primary
pressure to the setting range of 5.1 to 5.3 bar.
  
 My question is;
  
 Will raising the primary pressure affect the Control Pressure? ( Yes ).
  
 Is there a way to adjust the Control Pressure?( Yes, But by the experts. )
  
 How is it done? >> ( Take the fuel dist off and send it to me. )

The fuel pump doesn't create the pressure, all it does is pump volume of
gas. 
The restrictions create the pressure. The primary pressure can only be 
adjusted by a shim in the unit. ( Picture on my web site.) When it's right (

Yes )  it also creates a back pressure ( trying to keep the gas from going 
back to the tank) which will raise or lower the control pressure which in 
turn will allow the control plunger to up or down sending gas to the 
injectors. Speaking of injectors, Have they been cleaned or replaced. You
may 
be starving the car gas at high RPM because the injectors are partially 
stopped up.

Subject: Re: Re Delorean went BOOM

I realized I "misspoke" when I used the word [backfire}. You are
correct it is more accuratly applied to when the combustion pressure
comes out the intake. Unfortunatly once you hit [send] it is too late
to change anything! The point I was trying to make is the same anyway
which, as you agree, the timming of either the valves or distributer
is way off to allow the combustion to escape prematurely. This can
become dangerous because it can cause pieces to come apart and go
flying. It can also damage your hearing besides damaging parts of the
motor.

Assuming all you're dealing with is contact oxidation that can easily

Yes, quite true. But I must point out that there will *always" be 12 
vdc on that one pin to the idle motor, even it the ECU is not 
working. Checking for power there is pretty usless, especially if you 
reference it to another ground.

This is because the ECU sinks current to the motor, it switches the 
two grounds. The plus side is wired directly to the motor internally 
through the ECU, checking for it is of only minor importance. Or just 
do what those who can't repair it say: Yank the idle system 
completely off and make the car "better" than it was designed to be ;)

Gentlemen,

As All Hallow's Eve approaches I am struck by the urge to go in
costume which I normally never do.

This year, I want to be Marty McFly in the radiation suit. I have a
military issue gas mask, but I need a radiation suit, gloves and boots.

Someone on the DML makes these. They gave one to Mike Cohee, but the
radiation symbol was upside down.

If you could make one for me, or tell me where you got the white
jumpsuit and how you put the symbol on it, I'd appreciate it.

I'm willing to negotiate a price. Please contact me off-line.

I figure I'll pass out candy from the DeLorean in the rad suit and
have a few CO2 extinguishers, or dry ice on hand to make a little fog.

I may even have time and cash to make a flux capacitor. I'll finally
be able to shut my neighbors up, who keep asking me when I'm getting one.

Thanks,

Rich
