Engine won't start
I've posted before, i think, im not sure if im doing this right, im new to this forum...but i need help, my original post:
my 98 ram 1500 5.9 wont start, woke up one morning and it just wouldnt start. I hoocked up scanner i had code 300, 301, 306; multi-misfire cyl1 misfire cyl6 misfire, i replaced cap and rotor, spark plugs, wires, and coil still wouldnt start. Towed it to dealership they said it was fuel pump problem, so i brought it back to my house replaced it and still nothing, i have aprox. 50 psi fuel pressure, good spark, compression is about 120 psi average, put no.1 cyl on TDC and rotor was pointing to no.1 wire, so dont think it was timing. checked cam and crank sensor, no broken wires or dirty, would they show up on scanner if malfunctioning? i dont know what else to do, im stompped.....can anyone help?
please if anyone has any ideas please let me know.

I'm guessing you didn't get help with your first post vecause A) you posted it in the new member forum where it didn't belong, and B) you used a similarly vague title as this post (I have since changed it). We prefer members not use titles like yours because they are often ignored and because they have no value in a search.
There are lots of reasons why a vehicle won't start. The first things to look for are whether you have spark and fuel. There are a number of threads that might help you that can be found by doing a search. Good luck.

i have spark and fuel, i had all this before i started changing things, i checked spark plug wires firing order too many times to count to make sure i didnt screw them up, only reason i changed coil is cuz a buddy suggested it, and fuel pump, cuz dealer said that was problem, dont know what is going had no symptoms when i parked it, and then following day, had no start. and thats where my journey began.

tried spraying with starting fluid (pyroil), had no affect, if i turn key to run position and cycle a bit before i crank, it will studder a bit like its gonna fire, then just stop and keep cranking, every once in a while, it will run for like half a second, then just cut out and keeps cranking, had fuel pressure gauge on it while cranking, and pressure stays constant., same with spark (in-line spark tester used) never stops sparking, and injectors are pulsing (tested with noid light) to make sure they were firing, put brand new injectors in today as well, still no result.
