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.

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

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.

Might be the ECU, we chased a spark issue for hours and hours on one of our local guys KA swap and the next day he plugged in another ECU and fired right up, I highly recommend trying another working ECU before you continue to shoot in the dark, might be that simple, once you eliminate the ECU as a cause then it is easier to move on.

 

Also, everything needs to be plugged in or the ECU will get codes and not run correctly.

"Still need to get knock sensor & intake Tube "...

 

.....That "intake tube" is important to the operation of everything. The IACV needs metered air after the MAF for the engine to run correctly. Leaks in the intake will make it run like cr@p. Try some spray carb or MAF cleaner in the IACV also. Knock Sensor is $40 on rockauto.com FYI...
