If there is no fuel to the inlet of the lift pump then something is wrong with the tank,tank screen or hard fuel lines... if there is no low pressure fuel reaching the inlet of the IP then there is something wrong with the lift pump or filters... if there is no high pressure fuel reaching the injectors then there is something wrong with the IP. Pretty easy to eliminate in that order.

If the diesel won't start and the GPs and Starter are doing what they are s'posed to be doing then there's either no fuel or the compression is gone.

If it were me i would treat it as if it had been run dry of fuel and work through priming the fuel up to the injectors before i did any repeated cranking or spraying anything in the intake.

It may still pull air though even with fuel getting there. Sitting may have let all the rubber dry out. Wild goose chase of an air leak. Once again, I recommend towing it to get it running. Check compression after warm. Then look for air leaks.

Peter,

I encourage you to buy it and give it a go. Try and fix it yourself. You've been sorry for such a long time that you sold your 240D after realising that the problems could have been easily fixed.

Things don't get much more simple than a 240D.

This might be a dreadful mistake - this might not be the car for you - but if you don't jump in there with both feet and and try to get something for a cheap price you'll never know.

I'd never tow start a car that has been sat still for a long time - I value my teeth! I'd have to make sure the bloody thing would stop on command - that takes a long time to sort out and to give me confidence which I feel would be better spent getting the effing engine running.

Those are pretty much my thoughts at present. I won't have time to check it out before we leave town for the holidays. But if it's still there when I return in the new year I may well investigate.

Problem is my financial situation. I just don't have money to throw at a major problem. If it were any other car than a 123 there's no way in hell I'd even be considering looking at a non runner. But desperate times etc...

I'm a bit stunned at the amount of traffic this thread has engendered. Gratified too. I appreciate the comments folks have made. This is a great forum.

I would never try to tow start a car with an automatic transmission.
I can't really explain my intuition on this... internal fluid pumps, direction of pressure, torque converter... some have those things , some do not... just against my religion....and then multiply it having sat for a while...

I lived in your area for a year... the one thing you certainly have going for you is the total and complete lack of any rust on anything...

I mean BARE metal can sit out for decades and not get more than a light sheen of oxidation in AZ... it's crazy. paint and interiors suffer massive sunlight degredation, and perfect top of the line a/c in these cars is a pitiful joke in the 135F temps out there... but at least you don't have the massive humidity too...

Is this an auto? Whoops.

Definitely check the brakes first. Lol.

Definitely on flat ground. Or if you really don't give a .... Short rope behind a tractor or something that won't mind the contact. Lol. Don't leave yourself room to hit hard enough to knock out your teeth.

I just wouldn't dump time and money into a fuel system to find out it has bad compression.

In regard to sitting, I put oil in the cylinder and let it sit. Rotate by hand after it drains through. I have a drill pump with a small line that goes down the dipstick (it's for changing the oil in a boat), and I'll Pump the oil through the valve cover.

Or use starting fluid to get it going. Just don't kill yourself to find bad compression.

But yeah my advice comes with the warning that I'm a redneck. I've had tractors that literally don't have brakes, leak fuel on one side, and shoot flames on the other.

If you look up a road on the big island of Hawaii called "waipio," I've had to crawl under a truck halfway up and hook up the transfer case linkages. That was beyond safe, but I trusted my buddy to keep his foot on the brake. The other alternative was backing down, way worse.

As I get older I learn to not get in these situations. Haha.

This is my Plymouth, it's retained this same patina for 15+ years. No rust through at all. A nice protective coat of surface oxidation protects everything underneath here in AZ.

leathermang · #24 12-17-2014, 04:27 PM

Do you know how good that Plymouth would look with a good paint job ?
With those straight clean lines.... I assume it has a 318 two barrel with auto trans ? Or 225 slant six ?

uberwasser · #25 12-17-2014, 04:56 PM

It's a Savoy, base model. If it was a 2-door, or a wagon, it would be getting restored. As a four door, it's just not worth much. And the interior is pretty wrecked. Serviceable, but nasty looking. So a nice paint job would look strange without lots of interior work too. Mechanically, it's been gone through.

It's a slant six. Used to be a 3-on-the-tree. That transmission died, now it has a 3-speed from a Dodge truck with a tall Hurst floor shifter. It's a wanna-be rat rod

I will be inheriting a 1964 Coronet (318 with auto trans). That one is the one to get the restoration inside and out, when the time comes.

The car in question was a manual. Unfortunately it's disappeared from the listings now so it appears it is not to be. Oh well. Too bad this time...

Phillytwotank · #27 12-17-2014, 09:05 PM

Somebody probably fired it up and drove I home with 'em.

leathermang · #28 12-17-2014, 09:14 PM

That is sick....LOL

Lucas · #29 12-17-2014, 11:42 PM

Lol. Been there. Seller saying multiple times it will have to be towed. Handed him the cash, hooked up some cables, sprayed some starting fluid, and drove off throwing a peace sign up. In Cali we say "late's".

It was probably a horrible car OP. You will find a deal.

Junkman · #30 12-17-2014, 11:47 PM

Uber, does the Coronet come with all accessories displayed?
