Where me with problems

[Momohenri]

Hello everyone, I'm having problems again. After a lot of searching, I finally managed to start my B2's engine, but it's not running smoothly. It vibrates a lot, and the Bdtc is at 10°.
It runs for about 2 minutes then stops when it starts to get warm. The oil warning light stays on, even though the level is good.
Another problem is that there's a loss of current in the circuit. The battery is completely flat overnight. Even a test light doesn't come on. I have to disconnect the ground to prevent it from draining. I've pulled the fuses under the dashboard one by one, but it's not coming from there.
Any ideas?

Well the first thing to start with would be to put an oil pressure gage on it. Verify you have oil pressure.

Then I would track down the parasitic draw that's killing your battery. Google parasitic draw testing... them take your DMM to the vehicle and figure out where the draw is coming from and correct it.

Then ensure your charging system is functioning properly.... to ensure the engine management system is working with proper voltage.

Remember... when setting timing... the SPOUT has to be disconnected when setting base timing.

The gasoline has been in there since about October, could it be worse? The Spout was disconnected for the timing .
I don't understand what you mean by Google parasitic

It's an electrical system test. Read it and understand how to do the test. Then find what's drawing your battery down.

Since October isn't old... not old enough to make much of a difference.

Thanks, I'll look into that tomorrow, it's late here.

Do you have access to a multi-meter?

 

[Momohenri]

I have an Astroai RMS 6000 multimeter like the photo, I read and reread the instructions to choose the function but it remains at zero, or it does not go or I do not understand why it does not find a current leak, I test by disconnecting the negative from the battery and I test between the battery and the negative wire as I saw on several videos.

Well, I found out why the engine was shaking. I don't have enough fuel pressure. I'm at 20-22 psi when I need +- 35 psi. It's starting to get bad. Every time I do something, another problem starts. I have the two-pump system

 

[Momohenri]

ok, I did some tests again, the battery is at 12.4 V but I only have 11.9 V on the pink/blue wire that goes to the pump, would that explain the slightly low pressure at the rail?

 

[Uncle Gump]

Probably not...

Most all of the electrical components are designed to work between 9 and 16 volts.

11.9 volts... that pump should deliver full pressure.

 

[Momohenri]

Thanks, all that's left is the filter and the regulator, I'll look tomorrow for a filter and if it's not that, well it's the regulator

 

[Uncle Gump]

Those do go bad...

Pop the vacuum line off and see if there is fuel in the hose. Sure sign it's bad.

For your parasitc draw, check for any aftermarket stereos that someone was to cheap to buy an adapter plug from the factory stereo harness to the stereo. Also as someone hacked in trailer lights? The one with the house wiring twist wire nuts caps are my favorite. You can always trust those to come loose and causing issues. Between stereos and trailer harnesses, those have been my biggest electrical issues on all kinds of makes and models. Replace any chopped up factory harness with the factory plug. Wire together, solder, and heat shrink and then wrap electrical tape to get back to factory. Also check for any other non factory wiring such as lights and anything else. Stereos and trailer lights are my biggest finds.

Amen, Brother!

The radio is disconnected so that's not it, however I hadn't thought about the trailer wiring, here in Belgium we must have separate orange turn signals, I had pulled wires from the side turn signals on the wings to power the trailer socket, it could be due to a bad connection or a bare wire.
Thanks for the suggestion
