how much fuel pressure does it have? why did you do the fuel pump, filter and relay?

when you say it won't turn over do you mean the engine won't start or do you meay that the starter doesn't crank the engine over? Won't turn over means that the engine is not rotating when you turn the key to the start position. If that is the case you would need to look at the starter, starter relay, battery, neutral safety switch and the ignition switch. If you mean it turns over (rotates by means of the starter) but won't start, you have to verify your fuel pressure is up to spec, you have ignition spark and injector pulse when you are cranking.

We changed the fuel filter cuz we thought it was clogged and it still didnt work so we tried the relay and then we changed the pump with a new one and it still wont stat like to put in drive. It cranks but it wont go. Im not sure how much the pressure was but I can see and how much should the pressure be?

fuel pressure should be 52 to 59 psi.

ok, I am still a little confused. maybe it the terminology. when you turn the key to the start position, is the engine turning over? (starter engaging the engine and cranking the engine making it rotate, turn over) If the engine does turn over does it ever start up? Does is start up and then stall out or does it never start up, just cranks only?Understanding what is actually happening is key into figuring out what is going on

I got it fixed it was the crank sensor. Thank you. It would turn over but never start. the starter was engaging but after some trial and error it was the crank sensor

yep, no crank sensor signal and you get no spark and injector pulse to run. Congrats on getting it fixed
