Adam, If you will look at my web site. I have taken some close up's of the PC 
boards. The link is below. Also, the relay's contacts are most likly burned 
up. The relay's are hidden, and no one ever thinks to replace them. They to 
are on the site. Maybe the pictures will help you Identify the parts. If not, 
let me know.

Jason, My car has sat for sometimes a month and still start right up. Does 
anyone know how long the pressure can stay on the syste. I don't. Call if you 
need any help with the adjustment.

Mike and others. Be very careful about chemicals in the gas, yes even 
injector cleaners. We have rubber Orings in the Fuel Distributors. Some 
chemicals will eat away at them and others will turn the SS diaphragm 
adhesive into powder causing the FD to leak.  Be sure to run the cleaner and 
get it out or dilute it as soon as possible.
Don't let it sit over night or day's. 
Mike, What you did was clean out the varnish or build up in the slits in the 
control plunger sleeve. They are only .2mm  wide. If a little varnish builds 
up in them, then the car will seem to have a hot start problem. This is why 
you raise the plunger about 1/4 turn clock to enrich or counter to lean. 
Again, Be careful about cleaners.

Unburned hydrocarbons usually indicates incomplete combustion 
generally caused by a breakdown in the ignition system meaning YOU 
NEED A COMPLETE TUNE-UP. If you don't know when these parts were last 
changed then replace the following:
Spark Plugs
Ignition Wires
Distributer cap and Rotor
Fuel filter
Oil filter and engine oil
Air filter
If replacing these parts doesn't get you to pass then you will have to 
find a shop that can adjust the mixture screw in the metering unit 
after making sure there are no vacuum leaks. Since you are at 30,000 
then you should also change the O2 sensor and adjust the valves but I 
don't think that is what is failing as the sensor usually will last 
longer than 30,000, that is just the interval that the EPA decided to 
replace them at BEFORE they go bad! Of course 1 tank of leaded fuel 
can kill the sensor AND foul the CAT.

John & Mike,

I think that the fuel injector cleaner must have cleaned something that was
sticking the check valve on the fuel pump.  I don't think that clogged slits
in the fuel distributor can cause a hot start problem, but I have heard that
a cracked diaphragm in it can.

> This may sound like a dumb question but what prevents the fuel pump from
> pressurizing the fuel lines with each start?


The fuel pump does pressurize the system with each start, but that doesn't
matter if there are fuel vapor bubbles trapped in the system.  The system is
designed to stay pressurized for at least as long as it takes the fuel to
cool down to a point that it will not boil at ambient temperature.  If the
pressure drops while the fuel is still hot enough to boil then it will boil.
The resulting vapor bubbles are way too lean to run the car.  Hence, the hot
start problem.

In the workshop manual, there is a graph that shows how long the fuel system
is supposed to maintain pressure.

Has your car ever passed the smog check since you owned it?  It is possible
that a previous owner has hollowed out your catalytic converter.  But more
likely I would suspect a problem with the Lambda circuit (and the frequency
valve in particular.)  If your mechanic isn't familiar with Bosch fuel
injection systems to know the difference then find another mechanic or try
to educate the one you have.  But if you can do that, then you don't need
him.  :-)

Since the car described has 30,000 miles on it and the O2 sensor has 
not been replaced, it sounds to me like it did not yet get it's 
scheduled 30,000 mile tuneup. I don't have my manual handy, but I 
seem to recall that the 30K tuneup includes O2 sensor replacement, 
cap/wires/plugs/rotor/etc, mixture adjustment, timing adjustment, as 
well as valve adjustment. If your car has not seen its regular 
scheduled maintenance yet, then you might consider having this done 
before starting to replace parts.

The catalytic converter should have a pretty long life -- I just ran 
my 150,000 mile DMC through DEQ here in Oregon and it passed fine 
with the original catalytic converter still on it. Premature 
catalytic converter failure (and O2 sensor failure as well) can be 
caused by catalyst contamination sometimes triggered by the use of 
leaded fuel (lead is only one of several effective catalyst 
contaminants). I've also seen catalytic converters that have failed 
mechanically where the honeycomb catalyst has broken up and in the 
form of rubble in the housing (this also generally resists exhaust 

Fortunately, the problem you describe sounds like a run-o-the-mill 
tuneup issue, and it sounds like your car might be due for one anyway.

Subject: DeLorean Spring Social in NJ - 4/26-4/28...

SPECIAL ANNOUNCEMENT!!! An extremely interesting and "rare" car will be on display at the Spring Social. No, it's not a DeLorean or a Lotus. It's something that I'm almost positive none of you have seen. There are only 3 of these cars in the USA! I'm not disclosing what it is. You'll just have to come and see it for yourself! :)

Time is running out to reserve your hotel room for the DeLorean Mid-Atlantic club Spring Social in Flemington NJ. The last day that the hotel will be holding rooms for DeLorean owners is this Friday, the 12th of April! If you don't reserve your room by this Friday, I can not guarantee you a room. I have absolutely no control over their booking and I have reserved no extra rooms for myself or anyone. In case this is the first you've heard of this event, here's some info about it:

Day 1:
It all starts on Friday evening when "out-of-towners" check in to the Hampton Inn hotel in Flemington NJ. There will be a room where Rob Grady will take your questions about anything DeLorean related. It will also be at that time when you can sign up for your car to be inspected the following day. From there, we'll move on to dinner at a really great Italian restaurant which is not more than 1 mile from the Hotel. After dinner, anyone who is interested can either return to the hotel for a good nights rest, or can hit the town and enjoy some beverages.

Day 2 - The main event:
On Saturday, we'll gather in the parking lot of the hotel to drive over to the main event. This year we'll be at Don's Jaguar Service, which is only about 2 miles from the hotel as well. At the location you'll be able to do many things. Club members will have the option to have their torsion bars adjusted for free, and also a general, quick inspection if they like. The torsion bar adjustment will be performed on those cars with droopy door syndrome, where necessary, by the door inspector. There will be a car show also, where you can enter your car to win a really nice trophy and other awards. Also, awards will be given for furthest traveled with their DeLorean! Club members who put their name on the list for the inspection from Rob Grady will be able to pull their car into the shop and put it on the lift for a more thorough inspection and possibly some minor repairs. Only a few cars will be able to be gone over due to the time frame involved. (The first people who sign up at the hotel are the ones who will get preference.) There will be food, music, raffles, and DeLorean talk all over the place. After the event, off we'll go to another location for dinner. This one I'll leave open to the decision of the group, but my suggestion is a local Chinese restaurant. They have an unbeatable, and affordable, buffet of all kinds of Chinese food; including Sushi! All you can eat for (I think) under $10!

Day 3:
Then, if you choose to stay until Sunday, we'll all take a ride down to Raceway Park in Englishtown, NJ for their Spring Car Show and Swap Meet! There are HUNDREDS of different kinds of cars and vendors there that day. It's really a great show. Let's swamp the place with DeLoreans!

Now, the costs for the weekend:
Hotel: Reduced rate $89/night (if you're close by and want to drive up and not spend the night, that's fine)
Dinner at Italian restaurant: Your choice (not mandatory)
Torsion bar adjustment: Free for club members (membership is only $15/yr.)
To attend event on Saturday: $5 to help pay for the food served that day
To enter your car in the show to compete for the awards: $5 (helps pay for the awards)
For club members to put their car on the lift for a thorough inspection: $20 (goes directly to club funds for future events and club costs.)

More info: The hotel is very nice. Normal price is $119, but I got a group rate of $89 per room per night. You can reserve Friday night, and Saturday night if you'd like as well. The room includes free continental breakfast, TV with cable, coffee maker in rooms, full shower with bath, choice of single king or dual queen size beds, indoor heated pool, Jacuzzi, small fitness room and there's a washer/dryer if needed. A maximum of 4 people can occupy a room. There are only 18 rooms available. 4 Kings with smoking, 2 Kings non-smoking, 3 Kings with handicapped access, 4 double queens with smoking, 4 non-smoking, and 1 double queen handicapped accessible. (The handicapped rooms can be occupied by anyone, they just have the special rails in the bathrooms.) If you plan on attending, you MUST reserve your room by April 12th. After 4/12, the reservations will be cancelled and open to the public... and this hotel books really quickly! To book your room, call 908-284-9427 and tell them you'd like to reserve a room with the "Mid-Atlantic DeLorean Club". Give them your credit card info and you'll be all set! The address of the hotel is: Hampton Inn, 14-B Royal Road, Flemington, NJ 08822

The Lotus Owners of NY are also invited, so there will be a variety of Lotus' to see there that day to see!

Rob Grady is donating his time to come down and perform the inspections and minor work on our cars. He is donating his time to help support our club. He will have a small supply of parts there that you can purchase if you like. I hope to see as many of you as I can at this event. It's always a pleasure meeting new, as well as veteran Delorean owners.

If you plan on attending, please drop me an e-mail to let me know. I'd like to have a "rough" head count. Please include how many people will be accompanying you as well.

Thank you,

I can only say one thing:
Don't try any adjustments as you can make things even worst. If the sensor
is 20 years old it is time to replace it. I'm sure this will fix your
