Narrowed It Down to Fuel
« on: May 08, 2014, 04:44:37 PM »

Hi All!
Its been awhile, I hope everyone is well.

So the car has been sitting patiently....for a while
In trying to get it back on the road I've
put in:

points, rotor, condenser, coil, ballast resistor,
spark plugs, and a battery.

I had the starter tested and it still works fine.

But it would not start.

Today I got another chance to take a look at it
and there is no fuel pumping to the carburetor.

So Im thinking a new fuel pump. Its going into
a 58 desoto fireflite.

I've had luck with the other parts at the chain stores
but I'm not sure about the fuel pump. Will any fuel pump
drop right in? not sure what i need.

Thanks!

Do you happen to know what engine is in it?  


You have a air compressor?  You can take a rag, wrap a nlow gun with a rag and pressurize the tank to push some gas up the line too.  Not too much air, we don't want to hurt anything.

Also, the carb should have a vent tube you can fill the bowl of the carb through it, then check that the fuel actually pumps out of the carb.

There is also the possibility that it is not the pump itself, so, diconnect the fuel line from the carb and place it in a glass jar (DO NOT USE PLASTIC), and turn the engine over until gas comes out and into the glass jar to verify it is good. If you do get gas this way, the needle is stuck in the carburetor, or the float is stuck in the up position and needs to be cleaned..
 
An additional thing to check, agian with the glass jar or a metal pan in this case, disconnect the fuel line from the fuel pump before it goes through the pump to make sure there is good flow and no blockage from the tank to the fuel pump (a clear glass jar allows you to see junk in the fuel).

Just don't be like me and set a $60.000 DeSoto on fire with starting fluid.  LOL

OK, someone has to ask: you did fill the tank with some gas?  (Not trying to be cute but have seen it happen....)

OK back at it today.

Thanks Snotty haha I've been guilty of doing

that once before...just once though...for now

Thanks for the insight dana44
The carb is now spitting out gas like before.

Dang POLARACO talk about a hot rod
I've been giving it a healthy dose of starting fluid
tried some gas too

BUT still no go

It did seem to want to start

Maybe its not getting spark now?
I know I've got the spark plugs and wires
set up right. and I didn't move the distributor
when the new points went in.

How should i test for spark?

Thanks again!

Easiest way to check for spark is to pull the coil wire from the distributor cap and hold on to it.     DON'T DO THAT!  Hold the wire near a metal part and spin the starter.  A bluish yellow arch should jump about 1/4 of an inch.  
Check to see if you have voltage at the + side of the coil.  Should read around 9 volts.  Check the Ballast resistor.  It should read 12V on one side and 9 on the other.  Make sure the wire from the points to the coil is in good shape.  Points gaped properly?  Cap clean?  Rotor clean and solid?  Condenser good?

Hey POLARACO
Thanks! so i just tried that.
I got spark from the wire.
And the readings on the
multimeter were dead on.

The wire to the points from the coil
is good. I remember setting the points
to .017
I'll double check them to be sure
The rotor and condenser I put in new along
with the points
And the cap looks good and clean.

I checked the spark at the points and is was
there. not sure how bright its supposed to be
but it was blue.

Thanks for all the help.
Hopefully it'll be back on the road soon

You don't think you flooded it do you?  Take a peak at a plug and see whats going on there.


Spin it over to top dead center and see if it's near #1 on the cap.  If it's 180* out, turn the crank again.  Are you sure the firing order is in tact?

Well, you have spark from the coil, now see if you have spark from a sparkplug wire. You can stick an old plug into the boot then hold the threads against something metal to see if you get spark at the tip, that way you can verify no error inside the distributor to the plugs themselves.

Hey Thanks again!

I swear with all this help I'm getting
I want to buy you folks some lunch

Soooo I was cautious not to flood it
or drain the battery

I got it to top dead center.
but soon after realized that my buddy
had picked up his tools
so i couldn't take the spark plug out

BUT

I did have some layin' around so I was able
I stuck one into a couple wires and did see a spark.
I havent done it before so im not sure how intense
the spark is supposed to be, but it was there

The one thing I have not messed with is the timing
I wouldnt know where to start

I did check the firing order in the service manual
even labeled the wires

Thanks again!
You all are way too cool!

18436572  It's on the intake manifold on some engines as I recall.



Do you know if the wiring has been tampered with on this car?  So many have been butchered

You said it "tried to fire."  If it's trying, turn the distributor a little while starting.  It helps if you have a remote starter button so you can turn it wile the motor is turning over.  You can see what I mean by viewing this video of the first starting of my son's AMC 401 (407) in his '73 Gremlin:

Ok,
Im back in town and can get back to the car.
So I haven't been able to get to it or post.

POLARACO and Snotty,
Thanks for the tips I'll get to it

Snotty thanks for the video!
Cool car by the way

I'm not sure about the wiring
as far as it being tampered with.

It was running fine
until it just cut out on the road.

Thanks again!
