I recently installed a new 3/8” fuel line in the back behind my bbk intake I had to remove the upper intake to do so . Since I was already back there I just went a head and replaced both 3/8” lines, put it back together started it ran for a second then flooded itself out. Had gas coming out the bbk throttle body. I replaced the fuel pressure regulator but problem is still there. Help!

Good afternoon,

I would disconnect the injector wires and turn the key to on and see if they still flood the engine. If it does, then the injectors are bad.

https://www.2carpros.com/articles/how-to-test-a-fuel-injector

If it does not then either the wiring to the ECM has shorted or the ECM itself is bad.

I attached the wiring diagram of the injectors wires to the ECM and the location of the ECM.

The test is done with the engine off and key on.

Turn the key to the on position. Remove the connectors for the injectors and see if they still spray fuel.

Okay, so it starts now but keeps stalling. I’m guessing from all the flooding that occurred.

Good.

Yes, give it a little time to burn off all the excess fuel.

Let me ask you; how do you set your timing if you can’t get it started?

Okay, technically you cannot.

You static time it to get it running but the final needs to be done when it is running.

Get a test light and put the clip on the negative of the battery.

Then put the light on the negative side of the coil.

Make sure the engine is on top dead center compression stroke and the rotor pointing to the number 1 cylinder.then rotate the distributor until the light goes out. That is commanding the cylinder to fire or it is top dead center for timing.

No matter. You need a new battery. It is sulfated and will not take a charge.
