Great to hear I know that this is my final problem haha I just dont want to believe it. I reached out to  https://seideldieselgroup.com/contact/locations/boca-raton-fl/ and was quoted 1450 for the rebuild they are located in Florida. I am in Chicago would love to find someone local. Did you remove yours on your own if so was it difficult and how was reinstallation?

Thanks !

Removal and installation of the pump is not such a bad job. We can help you through it if you decide to take it off.  If you drove it around for about an hour you are getting closer. Sounds like you may have an ignition problem also if your points are getting burnt. Make sure you have the correct coil with matching ballast resistor or your car will never run right for long. Keep an eye on the fuel pressure, since it does not take much dirt to plug the little screen in the electric fuel pump. Once the fuel pressure drops below 12 psi. all kinds of strange running and starting problems happen.

Also check that the condenser is on the negative side of the coil if not mounted on the distributor.

Sounds like you are isolating problem areas. After sitting all that time, I am amazed that your fuel pump (not the injection pump but the one near the fuel tank at the rear) is working that well. 

If you end up needing a fuel pump rebuild, I heartily suggest Bob Youngman (Baron Youngman on this site) if you have the short pump. He rebuilt mine and it came back almost as a work of art. He uses materials not available when these pumps were new and has rebuilt several hundred of them. He guarantees his rebuilds for three years. Your car would have originally had the "long pump" but its possible a previous owner replaced the long pump with the short pump. As Joe Alexander pointed out, if you don't get at least 12 psi, lots of weird things will happen.

Good luck tracking down your issues. Lots of help on this site.

I know Bob he is a friend of mine. I rebuilt the fuel pump meaning replaced the o rings cleaned the filters and changed the impeller. I am getting 13psi at the furthers point of the car the cold start solenoid. My car has a short pump.

Thank you ☺️

Hey guys my pump finally came back from being fully rebuilt by mechanical fuel injection. I thought I had everything set correctly 20 atdc and the pump gears were alligned prior to installation. the car barely fired up it took about 10 min of cranking and then giving it gas . When it did fire up it kept backfiring like crazy in the intake and the exhaust.  Is my pump timing off or is somthing else wrong  ?

Did you check the timing?
Also if you have points replace them with electronic setup.They are a pain. I could never get them right. I replaced using crane system. My fuelpump was also not free and i took it out and hookend it up to a power drill abd used all sorts of liquids including sea foam etc to stop it locking up. Eventually it loosended up and worked after i put it back but i think you are ahead of the game with a rebuilt pump. Other things to check is your fuelpump. You can get a carter pump if you have any doubts and keep it as a backup. Also add an extra filter from tank to pump. I used a wix filter and its clear so you can see if its any crap in it from the tank. My gas tank was blocked up solid.

Hey thanks for the reply. We had the timing set to 20 atdc and the pump timing was also lined up. Ive gone through everything on the car lol resealed gas tank fuel filters etc. plus wires caps rotors you name it. Im going to check if we had the timing set properly upon reinstall perhaps its off 180 for some odd reason.

Be careful that an ignition problem is not the root of your trouble. Backfiring through the intake can mean a lean running problem. Check the fuel pressure and volume again. You might also want to visit the intake fitting screen on your electric fuel pump to make sure it is clear.

I just went through the same thing with a friend who was starting their car after a restoration.  As a professional Mechanic I would have sworn it was a fuel issue.  It turned out to be ignition related.  The condenser had been moved from the distributor to the coil and it was connected to the positive side of the coil.  The points were burned from a couple minutes running.  I seem to recall you had some issues ordering a Pertronix igniter?  Install it.  Follow the wiring directions. If you don’t have one get one.  Also verify your firing order and rotation of distributor by bumping the starter with the cap off.  I once last days trying to start a Porsche 911 because a distributor diagram I found online had the direction of rotation backwards.

If all that fails I would pull the distributor and give it a good look inside. If the screw for the condenser is any longer than the thickness of the housing it will scramble the insides of the distributor.

Many years ago (1971) I bought a beautiful Austin Healey 3000 for $200 because the owner couldn't get to to run and his wife wanted it out of "her" garage.  We pushed it to the street and I went off with the title to DMV to get plates for it.  When my dad and I came back with the plates, a tow rope and my tool box we tried a few things to get it to run before towing it home.  First, we checked the electric fuel pump (working) and the float bowls (empty floats and fuel level correct).  Then we pulled the plugs to check the gap and for signs of fouling (new, correctly gapped plugs, smelling of gas).  Finally we pulled the cap to check it, the rotor and points (all new).  The points were gapped properly but the insulator washer was installed incorrectly over the the condenser wire end and point spring instead of underneath, grounding the points.  I put it where it belonged, started the Healey up and drove it away.

Hi

I’m having the same problem

Did you find a solution ?

After removing the cylinder head 5 month ago , we installed it back.
Motor refuse to start ?!
Fuel is arriving to the injection pump ( I tested it by removing the screw of the fuel filter ).
Spark are new and do fire.
Distributor is ok ( 123 Infinition ).

When I unscrew one injection line , fuel is coming out when I try starting but with very low pressure ?! and not much.

By leaving the engine 5 month do I have to do something special with the injection pump for restating ?

Thanks

Olivier

It has been a nightmare. I finally gave up and dropped it off at a mechanic and he has done everything I have  I even resent my mechanical fuel injection pump back out to the company that rebuilt it. My mechanic found rusty fuel in the tank which I had reseal professionally so this may have been the root of my problem. He was swapping injectors 3 would work 3 would etc. So now im going to order a new tank and pray that the fuel injection pump was rebuilt properly.

You mentioned that you replaced the injectors. Much has been discussed here that new injectors do not always work as they should. They should be tested for proper spray pattern. If you have your old ones they can often be cleaned. Kent Bergsma explains how to clean mechanical injectors on his YouTube video.

If you have fuel, spark (on time) and compression, it will run. Try a shot of starting fluid. If it tries to start, then the issue is fuel supply. Pull a plug wire, and install a spare spark plug on the loose plug wire end and hold the spark plug against engine ground and crank the engine. If you have spark then check to see if it is one time and also double check the spark plug firing order is correct and that #1 wire is in proper distributor location. Make sure your spark is happening on the compression stroke and not 180 degrees off time. Lastly check the compression to make sure the valves are closing and the cam timing is correct. You might have to install a fresh set of spark plugs often times they become fouled after all the failed attempts to start. For first start up I remove all spark plugs, slightly loosen each fitting at the injectors and then crank the engine until fuel emerges from each injector fitting. Tighten down each injector fitting as fuel emerges. When all six fuel lines are primed and tightened, I then install the spark plugs and start the engine.
