Rob.......I would sell you my left arm before this truck! As Greg and Nolan have suggested to me, once you put blood, money, time, and sweat into a truck it suddenly makes it worth alot more....so if you want to give me $5k.....i might consider
Jeff and others that are following along:
Just tried to start it cold and it wouldn't fire.
Put 3 ounces of fuel direct into the carb and with a few pumps of the skinny pedal she fired up and ran 8 seconds.
Repeated but gave it a little skinny pedal once running and it died quicker and did the air expelling noise through the top of the carb.
Put about 6 ounces of fuel in and it cranked right up and idled (with no extra skinny pedal) for about 25 seconds.
Fuel lines are pushing fuel and I see no leaks.
I did see some liquid that smelled like gas around the bottom of the carb (not drops just condensation really) where the exhuast comes out of the engine, but I don't think this is a vacuum leak....just exhaust/water vapor.
So is this a timing issue as it will fire with fuel directly in the carb?
I know that it has to do with the cylinders being at just the right position of the piston stroke when ignition of the fuel takes place. does this sound like it's off as wannabecrusin suggested? It is pushing fuel, so I don't think it's the fuel pump, but it could be missing the fire as it's off bc the cam and pistons are? Maybe the BTDC (before top dead center) being off is causing it to crank over with fuel directly in the carb, but not to stay lit?
How do I check for a bad coil?
Maybe I should go to fuel injection and not worry about it??!!!! Jrob seems happy!
Any suggestions on tests, elimination process tiral and error are greatly appreciated as I am getting frustrated that I can hear it run but not get out of the garage.
we can also discuss tomorrow night.....I may even get worked up enough to
in the parking lot if we discuss it.

Did you mess with the timing since it was running last time? Got to be a fuel delivery problem.

this is on a small block, but VERY informative
How to set your timing! - Car Videos on StreetFire
anybody got a timing light? you can do it by vacuum but I have read it's not as accurate

no haven't touched ANYTHING but the new fuel pump and the new tank plumbing....you still thinking fuel delivery?
starting to have nightmares that the cam lobe is jacked up and the pump isnt pushing enough fuel....ill recheck flow in some more spots along the line and im going to get a new fuel filter too.....for the one after my regulator

Did you put all the hoses back where they were originally? You "know" the fuel pump is pumping fuel?
- Thread starter

hoses are all back in original location.
I broke the line after the regulator and before my second fuel filter and got fuel pouring out....problem is I can't keep it running long enough to break the line while it's running......i was planning on getting Andy to help me with that tomorrow before meeting

thinking out loud
I did plug the fuel return line from carb to tank.....that shouldn't affect it though?
I want to try timing if I eliminate the pump bc it is hard starting and I just can't help thinking it's timing/misfiring.......once it cranks it runs strong though at idle
im just feelin in the dark right now.....I need more than 2 minutes to try cranking it while not holding a coughing 9 month old...that should help shed light on it.

Why did you plug the return line?
- Thread starter
- #371
because, like half the other lines on my truck, it was flapping in the wind and hadn't been connected for years.
it came off the carb and ran in circles from the firewall to the fan but didn't go over and down to the return line still on the frame rail so I plugged it after Greg confirmed it was useless'
can you help me by cranking it tomorrow for a few minutes while I check various spots bn the pump and carb for fuel flow?

Check for fuel flow at the carb.
Fuel filter.
Fuel filter.
Load it on a trailer. We can have a wrenching party at the Cherokee.
^^^^This......
Granted, I'm not there looking at it, but it definitely sounds like a fuel delivery issue to me. If I understood what you said, you said it'd run when you manually put fuel in the carb and cranked it, although it would only run for a short period of time? Like Bo-de-an said, check your fuel flow. Try removing the line connected from the fuel pump to the carb (don't know the setup without seeing it) Crank it a few times, and see if you get fuel out of the line. If you do, reattach it to the carb, crank it a few more times then go look in the throttle body of the carb while you're moving the accelerator linkage. You should be able to see the accelerator pump in the carb squirting fuel into it.
I'm wondering if whatever line you plugged might be creating a vacuum situation and not letting the fuel flow (sort of like trying to pull liquid out of an unvented container. At first, you can do it; however, with time, it'll build up enough vacuum where you can no longer draw from it. But, if it's vented, you can draw from it without effort...........) Again, without seeing it, these are just some initial thoughts

Is there gas in the tank?

going to check for flow tonight with Andy's help hopefully and get a new fuel filter
I would love this but I have no trailer.
That is why I brought up the plugged return line...I may unplug it and see if it does anything but I highly doubt it. I will defiintely watch for fuel flow while hitting the accelerator linkage
just over a 1/4 tank.
Thanks for the ideas fellas....Andy and I will report our findings tonight over a beer.
Be sure to buy clear fuel filters so you can see the fuel filling and passing thru the filters.

the one ive replaced i did that at Jeff's suggestion....its kinda opaque...but you can see it.
the other one is after the regulator and was a PO one and it's in a brass casing so that will go clear after hitting the parts store.
