Make sure the coil is getting power when the key is in the start position. I had this issue, turned out it was not one.. but TWO bad ignition switches. I had to swap out for a third.. really dumb.

 

You can check by spinning the dizzy with it in the on position. The plugs should spark.

The fuel pump should shut off when it gets to pressure. 

 

How are you checking for spark?

Whenever I think that I'm out of my mind for putting this much time and money into an old Datsun, all I have to do is look some of your threads to know that I'm not nearly as whack as you are.

You're going to skin a few knuckles, stand up too fast and bump your head, hunt around the floor for the nuts and bolts you dropped, invent a few new cuss words and when you're finished you'll say "That wasn't so hard after all!"

Pulled the wire coming from coil going to Dizzy. Then pulled a Spark plug wire. Fuel pump does go off after 3-4 seconds.

So I got the negative signal now. But now I’m thinking my Injectors are bad. Is there any way to test the injectors?

Best to know what the problem is before throwing parts at it.

Very true will yesterday I figured out some wires to give me the negative to injectors but still not getting fuel in. I’ve checked Fuel pump. I checked my return line to make sure it’s flowing thru. But when I check spark plugs they are Dry. The only code I get from ECU is 34 when is Knock sensor n I was told that won’t make the car not start

I would pull each injector and see if they are spraying in a decent pattern with direct power. If not then replace them, if they do then you could still have a wiring or ECU problem.

There is a resistance spec for the injectors. Ohm them out, that might tell you if they are bad. If you have one good one, swap it to the location of the bad ones. Make sure it still operates in each port...

 

If it works... then the others are bad. Don't waste your money on shit you might not need.

Do you have another ECU that you know works to check with?
