Replaced the fuel pump and it started a few days, then back to intermittent will start wont start. Starter was slow so replaced starter. Started and starts quicker but still intermittent start.

Scan for codes first see if that is causing problem may be a loose connection in ignition system.

I tried to scan it and all I got was red lights with just big plug connected, didnt even have sto hooked up(single plug). I have taking voltage readings at tank (blk/yel 12v and blk gnd). Couldnt get 12v. Put pressure gauge on shrader valve 0 psi. When key on (KOEO) no click felt at fuel pump relay. Put a new one anyways. Put in new ignition switch. I just know what to do next. Still cranks but won't fire. I did the starting fluid test and it started (shortly) as it should.

Check fuses 4 & 22 in underhood fuse box then check pcm power relay in same box. It may not be making good contact. Also check that inertia switch hasn't popped off. Fuel pump wire is drkgrn/yellow to inertia switch then pink/blk after.
