Help no start

[leftcoastjeff]

Ok so one moment it starts and runs great the next moment nada? Doesn't sound like a failing IP to me, but what do I know.
Got the battery charger on now.
The fuel did make it to the fender after a slight psst. (Finger actuated shader valve)
I've got clear tubing after the electric fuel pump, before the filter. Solid fuel when on!
Enough for now

One question,
can I get fuel to flow through the top of the IP if the advance on the IP is energized?
Maybe I can get some fuel with additive in there to free the fuel shutoff solenoid.

The psst would indicate air in the filter head. Since you have no bubbles from the electric fuel pump, the air could be entering from the Orifice Bleed Off or the a leak in the fuel head itself. This may be a red herring tho, because the electric fuel pumps are great for purging air anyway.

Yes, you can see if fuel exits the return line at the top of the IP while cranking. The engine must be cranking , because the fuel must pass thru the vane pump in the IP. All this will tell you is that the vane pump is working. Be sure to block of the return line end because it will have fuel in it.

Because of the intermittent nature of the problem, it may be a sticky or malfunctioning Fuel Shut-off Soleniod. It may be just a poor electrical connection to the FSS. You can rig up a jumper wire from the positive terminal of the battery to the FSS. This will bypass the exiting wiring.

I found a small leak I had not seen before on the top of the filter head where the blue wire is.

Swapped out the FSS, now it makes a clear clicking sound and starts so fast I can't believe it.

Something I have learned in the past, listen closely to anything Towcat has to say he seems to always have the info that is needed.
For instance I have used starting fluid in the past with success, but I had no idea that if the FSS is closed (no fuel going into the system) you cannot get the motor to fire with said fluid, no way, not going to happen! Actually slowed the rpms enough to worry me a little!
Gleefully

Calvin knows what these engines and trucks can do on a daily basis. Glad you got it running well again.

 

[leftcoastjeff]

Thanks go to this forum and all the good minded folks.
I really hate to love my truck and love to hate it too ......
Thanks again

No fuel these engines will fire and sustain run on either if done correctly....just saying

I tried to tell them

 

[leftcoastjeff]

Looks like we may have a disagreement.
I was unable to get or sustain fire with the smallest shot or the one second shot.
IIRC I have successfully used starting fluid in the past and it worked provided there was some fuel reaching the cilinders.
Not trying to make waves just looking for more info and less confusion.
Sorting it out,

Well, _I_ am certainly not trying to start an argument.
But before I added the electric lift pump, that was how I
routinely bled the fuel system. Started and kept it running
on ether, until the air was out of the lines.
When I got the truck, the selector valve was sticking, and
the pickup tube in both tanks was doing the 1/4 tank thing.
I didn't know about the pickup tube problems then. so I
ran out of fuel numerous times. I would add fuel to the tank,
pop it off (assuming I had enough battery left) on ether, and
keep it going until it picked up. Takes a delicate touch, and
something to jump the starter relay. Get it started turning,
and THEN add a very small squirt of ether. Too much would
lock it dead. You need to do it directly into the snorkel.
Works for me.

AND - one second is WAY too much. _

 

[leftcoastjeff]

Maybe that's it, I had no snorkel or filter in the way.
IF I said 1 sec. Which I probably did, it was a dramatization.
I was unable to put less of a squirt than I did and it still sounded bad and slowed
The rpms until it cleared out and went back to Normal.
Hmmm,

[fsmyth]

Yeppers. That would do it. Ether (and any other fuel) needs to be mixed with
a bunch of air. Sounds like you just filled up a cylinder or two, and it couldn't
burn. Like I said in a previous post, I had a friend who started his with a
gasoline-soaked rag for years. Haven't tried it, but I don't see why it wouldn't work.
