So even though I am getting fuel to the top of the injectors nothing is getting into the cylinders? Like I mentioned previously I did crack the hard lines on top of the injectors and get fuel coming out of the top. Does this mean I need to replace the injectors?
Again sorry for this I'm literally learning how all this works as I go along.
How much fuel are we talking, A dribble while cranking?
Here's an easy test. On top of your IP is a wire, unplug it, turn the key to on, and tap the wire to the post. Should be some sparks, and a click from the IP. If you don't have a click the FSS is stuck shut not letting fuel flow. You can either tap it gently with a wooden handle to try to liberate it, or look up how to remove the top and clean it.
Another simple test - there is a schrader valve on the fuel filter you can see if fuel comes out while cranking: either setup a switch/alligator clamp to manually trigger the starter relay, or find a helper, and crank the engine over. while cranking, push the schrader valve in, you should see fuel dribble out reliably. Hear hissing? It isn't primed up, you have air intrusion or fuel leaking back. Neither? The lift pump is clogged/blocked up or you have an issue in the fuel tanks like a broken fuel pickup or similar. Try switching tanks or adding 5 gallons of fuel. My old fuel switch takes a few tries before it willingly goes to the other tank too.
Check the fuel filter, see if it's gunked up. Or just get a new one and fill it with ATF or diesel.
