"Dr 914" is here to sell you parts. You are already on this forum, he should just answer up instead of asking you to mail him stuff. Why do you think you need an MPS with carbs? And why would a self proclaimed expert ask you to send him an FI part to troubleshoot your carb problem?

No, no, no.....This is when I had my FI installed. I was trying to narrow down an issue. Sorry I ever brought it up. My MPS has nothing to do with this thread.

I purchased a Dansk distributor from Pelican.

I am now thinking my timing is off. I am getting gas but not firing in sequence. I have no idea how to check timing.

The Dansk from pelican is the quivelent of a 009? Is there a notch on the top edge of the distributor body at what should be cyl #1?

I'm not seeing a notch. That is probably my problem. My plug wires may not be firing in correct order. I wired like my last distributor had them but this one may be different.

I have it wired the same way my FI distributor wires were.

Your FI fuel pump wires were energized/grounded by the FI ECU via the relay plate.

No worky for carbs.

I know. I did the SirAndy info for converting over to carbs with the extra ground wire. My pump runs now when the ignition is turned and cranking. However, it doesn't want to shut off when the key is turned off. I have the pull the plug off the no. 4 pin.

That doesn't make sense.

Per that link and its accompanying photo, you're actually grounding the T4b III circuit, "third" wire, which grounds the fuel pump relay solenoid, closing the circuit for the power side of the fuel pump. The power side of the fuel pump circuit comes from fuse S13, which is energized directly from the battery. That's why the pump comes on.

The fuel pump relay gets actuated by power through the power supply relay (PSR). The PSR is only hot with the key on, through fuse S9.

If your fuel pump is running with the key on, then that implies to me that there's an issue with your PSR circuit or your fuel pump circuit.


For reference, T4b-IV ("fourth" wire, bottom left in that photo) gets power when the ignition switch is in the "Start" position. If you ground that terminal it'll short circuit during cranking.

Unless I'm misunderstanding something?

Note that these are based off of my 1974 electrical diagrams.

With key on and pump running, pull the fuel pump relay. Pump should stop running.

With key on and pump running, pull the power supply relay. Pump should stop running.

Do both tests with key off.

Report results.

#1 - you need this jumper on your relay board (lower left):


(IMG:http://www.914world.com/bbs2/uploads_offsite/i890.photobucket.com-21449-1571847147.1.jpg)

#2. - you need to get a fuel pressure regulator and gauge and set the pressure to 3psi max.

My dual Weber 44's run fine with the above.

I finally had my fill of FI and ripped out the entire fuel injection in 30 minutes. I was finally able to clean my engine out nice Installed dual weber carbs. I'm going to hold on to my fuel injection if I ever change my mind or sell.

Question. I installed a new low pressure fuel pump so my lines are empty. When I turn the key, I can't hear it like my FI fuel pump. What is the best way to prime these when they are new?

Everything is hooked up except for the throttle cable. Should I disconnect the fuel lines to get the air out of lines. I do not know if these are vacuumed or not is why I am asking.

Fuel pump relay pulled, pump goes off.

No bueno. You either have an internally-shorted relay plate or someone has been messing around with your wiring. With the power supply relay removed you should not be getting power to the fuel pump relay solenoid Pin 85 and/or relay plate pin T4b-I, the upper right in that photo above, both on same circuit.

Edit: here's a screen capture of the circuit. You can see when the PSR J16 is removed, there's no way for the fuel pump relay (J17) to get +12V at pin/circuit 85. Without that, grounding T4b-III wil have no effect on the fuel pump circuit (30 to 87; connector TT14-13 goes to fuel pump).

Edit 2: is there anything connected to the T4b-I pin, the upper right one next to the grounding wire you installed?
