Oh my goodness, I finally found it! It's a clip that has a slight crack in it coming from the back fuel injector! Whew, so now just replace the one fuel injector and we're good! Then figure out that 6 cylinder misfire.

So as obsidian I found the leak coming from one of my fuel injector o rings and I replaced it and now no more leaks! Great so about the p0306 I replaced the coil piece from one from the junk yard now instead of a p0306 I now have a p0300 multiple cylinder misfire instead of my cylinder 6 cheap Amazon spark wires I think. :-)

I would not assume the coil is good since it is used. I suggest getting a new coil and retest.

I attached the procedure for the coil below and a picture.

If that does not repair it, I would check the fuel pressure.

Pressure
48 - 55 psi

Okay, I will try that. I don't think it's my fuel pump, it's priming just fine. But the MSD cool pack I had before gave me a p0306 code so I switched just the one coil pack. Now it's giving me a multiple misfire. I got some after market spark wire from Amazon I am thinking that may be my issue too. So I'm going to replace those wire and go with OEM from AutoZone and we'll see what happens.

I just don't get it! It's so frustrating and I'm so close. I found and fixed the gas leak now I just can't figure out what's throwing on that code. I got new sparks closest to OEM as possible, new wires. What is it?

You need to check the fuel pressure to be sure there is enough fuel supplied to the pump.

You can hear it run but that does not mean it is providing the correct pressure.

Would that throw on the p0300 code? Low fuel pressure?

That is the number one reason for the 300 code. Low fuel pressure.

Interesting and how would I test my fuel pressure and what would the measurements for my vehicle that I would be looking for?

I attached a picture of the test port where you attach the fuel pressure gauge.

The spec is below.

Pressure
48 - 55 psi

Did you use new plugs? Gapping the plugs will have little or no effect on the issue at hand.

What is the fuel pressure?
