Ok guys I am new to this site so please for give me if I ask something that has already been posted.
Here is the back story. I picked a 95 f150 with the 5.8l it ran ween I parked it 2 years ago and started the SAS swap. Fast forward the swap is done. I put a new battery in and starter solenoid. I have the bed pulled off and the fuel pump are working. I am getting fuel to the rail. I do have to go pick a fuel pressure gauge to check the pressure. I am also getting spark. The engine turns over but will not fire off and run it has hit a couple of times and tried but that's all.

I did the obd jumper test for the codes and I'm getting a 558 code. I'm not really wanting to pull the intake just yet. But I know I'm missing something simple. I will be checking the inertia switch tomorrow.
Any ideas are welcome and thanks in advance.
