RE: [Chrysler300] Hard Luck Award Nominee?

Hi Mark,

 

Yes, I remember someone mentioning the push rod.  I had the engine rebuilt
about two years ago, but I can't be sure if this was changed.  So to check
for the problem, get a new one and compare the length to the old one?  I
replaced the mechanical fuel pump just to make sure it was not leaking into
the crankcase as I was driving home and hoping this would solve the issue.

 

Dumb question, but here goes.  Does the push rod just fall out?  It seems
like it was catching near the bottom of the opening.   Does anyone know the
nominal length of this push rod?

 

Mark

Mark,
Sounds like a problem I had with my H a few years ago. The culprit was the
fuel pump push rod. It was worn down to the point that it couldn't push the
pump plunger enough to maintain fuel flow at speed. It was worn at the end
that rides on the camshaft. I purchased a new push rod from my local
Chrysler dealer, installed it, put on a new mechanical fuel pump, and it's
been working fine ever since.

Hi All,

I met some new and familiar people on Monday night in St. Louis, just
assing through on a business trip with my '63 300 convertible. Thanks for
he hospitality! It was eventful!

Monday afternoon - The 413 started gasping for fuel on the way down to St.
ouis. I bought a new fuel pump, but did not install it. With the help of
arl Bilter, Paul Holmgren and Noel Hastalis, we determined that it may be
n electrical problem. I added some new premium fuel. Same problem, off
nd on. A burst from the electric fuel pump seemed to help the situation
or a little while.

Tuesday morning -I had a terrible bumping noise coming from the 300.
hanging the tire to the spare (left front) did not help. I had to limp the
00 to Highland, IL. The car was bumping all the way down the road and I
ould not get more than about 30 MPH. I found a shop in Highland and he
oticed the problem and changed the left rear tire. I had a separated belt
ccur in the left rear tire. The tire, after the air was removed, looked
ike a hard-boiled egg!! I had to drive home on a 20 year old spare (LR)
nd not the same size as the rest. 

Tuesday afternoon - Power loss continues. I put in a new coil in
loomington, IL thanks to Noel H for supplying it. Problem still
ontinues. Electric pump keeps me going.

Lexington, IL - purchased/installed a new condenser for distributor. This
ame problem/fix occurred in the past with a '69 Chevy Bel Air. However,
his time, problem continues.

Dwight, IL - I changed the mechanical fuel pump in the parking lot of the
APA at 5pm. It ran well for 15 minutes, then the problem continued and got
orse. I had to hold the button on my electric fuel pump to keep the car
unning. Finally, I had to hold the button all the way home, about 100
iles off and on!! The old fuel pump did not seem to be leaking any gas. I
hecked the oil and it remained 1 quart low over the trip, so I did not
hink there was a fuel leak in the mechanical pump that went into the oil
an.

The electric fuel pump (bought from John L) suggested a filter (which was
nstalled last fall). I think the fuel filter may have got clogged up in
ront of the electric pump??. The mechanical pump would not get the gas
hrough the system, but the electric pump would keep the car going. So, for
he last 50-100 miles, I had to keep the electric pump running manually!

The only way to get gas thru was to force it using the electric fuel pump??
he only other thing I can think of is possibly the carburetor, AFB 3256 SA
'63 New Yorker carb). I will change the pump filter (or eliminate it) and
ee if the problem continues. I never had this problem even when I used a
uel filter in front of the carb. What a day!! I lost a lot of friends on
-55, especially the semi truck drivers!

300ly,

Mark Lindahl
