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?

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?

Wire injector to.12.volts,but like only second or two. Should hear it click and pass fuel or carb cleaner thru it.

Just wemt thru this, had to get new ones. Cleaned the old and failed after 5 mins.

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.

Sounds like it's time for new ones :)

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?

Yea I got 3 new injectors. But still having start up problems. So now I think timing is issue. But I got it to start n idle fine. Sounds ok. Still need to get knock sensor & intake Tube

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...

Why only one inj, troy check that the other three from ECM are hooked up. This was a running motor right ?
