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?

So I dissected the bad ECU to try and pin down the exact point of failure.


There is nothing apparent that I could see, no real signs of water damage or burned circuits.

I really don't have the equipment, know-how to test the whole thing.
