Without reading all of the details already posted, I have a few questions:
Did you pull the tank and clean it out?
New lines and filter?
Is the fuel pump OK?

There are more than a few jeep experts kicking around the local area - I am sure they can be lured out of the woods with the beer enticement. In any case, the Rotters can help with the beer fridge thing!

Good luck.

Not to hijack the thread but is it not time for the Rotters to gather for a ogle-fest chez Gracie's?

These are the Apprentice Motor Mechanic questions I need. I'll report back.

The sender unit on the tank was removed and replaced once upon a time. Some of the little screws are missing.

The lines have been disconnected and exposed to the air. Other than blowing out the spider eggs, and reconnecting the ends, why replace them?

Hmm, fuel pump? Hafta go read the manual to see whether it is in the tank or in the engine compartment.

Check your filter for deposits. That could be a good indicator of contamination. I would recommend replacing the lines if upon inspection the inside of the tubes produce rust - you will have to find a way of pushing a thread thru the line (suggest blast of air), attach a small but reasonably big enough swab to the line and pull her thru. Look for "crap" - which is anything that should not be there. Chances are there may be varnish from evaporated gas or other particulates that inevitably made it into the fuel tank.

Or, you could use the Hammond method - soak in chemical cleaner and then blast the crap out the lines with a high pressure air hose...do not look in the other end of the line when doing so...and don't ask...

In any case, if you are confident in the condition of your lines, I suggest you carry on and inspect the fuel pump.

Often the fuel pumps will dry out after sitting an extended period of time. The bit of crud in there can cause the one way valves to not work. Sometimes merely priming the pump with a bit of fuel poured down the line will cause it to develop suction again, other times you have top open it up and clean it out.

A major problem with the old M38A1s is that the rather course fuel fiilter built into the tank does not screen out the really fine particulate. These can build up in the fuel pump causing it to not pump, or else get into the needle valve and cause the jeep to flood, especially when it is hot and sitting at a stop sign. An inline fuel filter installed in the short flexline right before the pump will cure that problem.

So knowing my limits, I conceded that my mechanical knowledge is limiting my M38Al's advancement back onto the road. My regular car mechanic has some quiet time during school spring break, and agreed to put the Jeep in the corner of the garage for time to time work. He has a short list of things (all mechanical) to work on.

I refilled the tires after a long winter, and with a long-shaft jack lifted it off the jackstands. Then I mounted the A-frame tow bar to the bumper. The family minivan, otherwise known as the prime mover, was backed down the driveway until the remnant snowbanks stopped me. Using the van as an anchor, with chain, tow straps, and an 8-yr old boy on the handwinch, the Jeep was slowly extricated from the Montreal Driveway Shelter. The boy was quite excited to help.

Out in the bright sunshine, several things happened. The 2 batteries held their charge perfectly over the winter. The accumulated old and new parts were sorted out into big plastic tubs. Humidity can accumulate in sealed parts bags left outside. The rust scale and tree leaves were vacuumed out. I replaced the windshield washer pump with one from the OMVA sale in Kanata 18mos ago. I diagnosed that the choke cable is verily uncooperative and permanently seized. Fortunately the fording handle and its cable are the same on the other side of the firewall. But the best thing was meeting a fellow who literally skipped across the front snowbank and introduced himself saying he had a Jeep like this too! And he lives in the neighbourhood!

For the collective wisdom - the fording crankcase vent lever on the fuel pump, is the normal operating location up or down? The damper on the air intake is wired off.

For Alex Blair - standby for "Jeff" to call wanting to buy ordnance parts and shop manuals for the M38A1. $$ $$ $$

For Clive - the sap is running!

After a year in the hands of Joel Bellerose in the wilds of Arnprior, the collection of manuals that was Alex Blair's is now in my posession and I will be happy to talk/e-mail "Jeff" about (Canadian) Jeep manuals.

hi Grant..
No call from the varlet yet..maybe Terry can give us a number or get him to call us for some manuals...You 'da man....U...AL...!!

The M38A1 CDN3 has: new plugs, new coil, new condensor, new rotor, new little rubber washers between the distributor cap and the cover (packed in Oct 1951), new fuel pump, freshly charged batteries. The wires spark. The plugs spark. The carb flows. The fuel lines flow. The gas is fresh. The only weak part is the starter isn't turning fast enough to kick over. I've tried ether spray, choke, stomping the accelerator, and turning it with the feeds back at neutral. But it just won't kick!

Short of starting under compression, what else can I do? Is there some electrical test I can do to see if it is getting 24v vs 12v?
