L-Jet issues, Injectors not injecting Options

[echocanyons]

Hello,

I have a 75 1.8 with L-jet, it seemed to be running fine aside from a possible bit of a hard cold start.

I was driving it and suddenly the engine died, I looked in the engine compartment and the negative battery cable had popped off.

It has getting good spark.

The injectors do not pulse at all and can't seem to figure out the root cause of the problem.

I have tested the dual relay and have installed a new resistor pack, thinking that this was the issue, but still no luck.

I do know the fuel pump is working (I did not test the pressure) the AFM seems to be functioning.

The white wire connected on the same side as the condenser on the coil.

Could the battery cable thing have toasted the ECU?

How exactly do the injectors get the signal to fire? They are all batch fire right?

Are the injectors pressure driven in as much as they will not fire if there is not enough pressure or will they drip fuel?

I don't remember but do the injectors "click" when the recieve the electrical signal to fire?

That white wire that hooks up to the (-) terminal on the coil carries the ignition points signal to the FI system and tells it when to open the injectors. All four open at the same time, in fact.

My first thought would be that the white wire is unplugged, but you said it's plugged in. I would check for other wires that are unplugged as well, particularly grounds, the air flow meter, etc. I would also think about what could have gotten knocked loose when the battery became disconnected or what else could have happened at that point--such as, what did you touch when you put everything back together?
