Help! Fuel Pump Noise! And Fuel Smell! Help!

["Stian Birkeland" <dmc_norway@xxxx>]

I hope someone can give me a quick answer to my sudden problems!

My DeLorean has just been serviced by my local garage. I purchased the Fuel 
Pump Kit from DMC Houston, because I decided I wanted to service this part 
of my fuel system. And sure enough, some of the hoses were quite rotten 
according to my trusted mechanic.

Previous to this I had also had a little fuel smell inside the car, and the 
fuel pump gave out a irritating noise once in a while.

So with the fuel pump kit ready, I thought everything was going to be ok 
now. What happened was this:

After the fuel pump and hoses was installed my mechanic tested the cooling 
system and let the engine run for about 1 hour (yes, one hour!) to make sure 
EVERYTHING was ok. The car sounded like new. The coolant system worked 
100%. The car started at once, no problems. No fuel pump noise, no fuel 
smell. Then they gave the car a good wash as to make it presentable to me 
when I came to pick it up.

I saw my DeLorean glistening in the sunlight waiting for me to take her home 
today preparing her for an upcoming car show this weekend. I walked into my 
local garage to fetch my keys. I didn't get them.

There was "something wrong" with the fuel pump they told me.

Turned out that after they had washed the car and drove the car outside, the 
fuel pump had began making a terrible noise all of a sudden(this was a new 
Bosch fuel pump), almost as if it were struggling. Much more louder than my 
older Bosch fuel pump!

My mechanic wanted to let me hear this noise in person. He got into the car 
started it....took about 5 seconds to start it (before it had started at 
once by the turn of the key). The engine ran for about 10 sec. then the 
terrible noise came from the fuel pump and there was also a strong fuel 
smell. The noise could be compared to a loud constant humming. Very loud. 
Very, very loud. Listen to it for one minute and you would get a headache.

With all this happening I must still tell that the engine ran fine during 
all this. No problems. Engine is 100%. Idles perfect. Runs like new. But 
theres definitely something wrong with the fuel pump.

At that time the clock was 3.00 and the garage about to close. They put the 
car back in and said that they were going to have a look at it tomorrow 
morning.

They also said that they really hadn't a clue to what just had happened. One 
person passing by joked about that it might be the water that did this. Not 
funny.

In any event, my trusted mechanic assured me that they are going to find the 
fault, then correct it cost-free. At the same time he admitted that they 
really didnt have a clue as what to look for since everything worked to 
begin with. I was asked to find out some clues for this. This is what Im 
doing now. We shook hands and he told me that eventually they will find the 
fault and that there must be some logical explanation to all this. My 
problem is that I must have the car ready tomorrow because of the car show.

I have been thinking, are there any parts that might have loosened inside 
the fuel tank? The tank has half of gas in it, yet I have still been 
thinking that maybe the pump sucks in air/gas fumes together with gas????

Did I say that I have a car show to attend on Saturday? Im so afraid that 
this may take some time and that I dont manage to have my DeLorean ready, so 
PLEASE:

If anyone can give me a tip on what this might be then I can tell my garage 
tomorrow morning so that they don't spend time on something that is not the 
problem. What can have caused this?

Stephen? Warren? James? DMC Joe? Darryl? Rob? Ed? Anyone???
I hope I wont be stuck and not being able to attend the car show...


Please help!
