Im recently experiencing a weird issue when starting. On the first turn of the key, it won’t start. But when I let the key go back to ACC and then try to crank, it immediately starts right up. Very repeatable as I literally just did it three times in a row.
Cranking is very strong and the battery is only a year or two old.
Any ideas? Do I possibly have a fuel pump going bad?
The tach jumps when I first turn the key but stays at zero while it’s cranking (I just checked).

I tried turning the key to ACC and letting it sit for a few seconds before cranking. Still had the issue. I then tried turning to ACC then letting the gages all bump and go back to zero. So far that has it starting. I’ve just never had to do that before.
Would I be correct to try changing the fuel filter before changing the fuel pump? As far as I know it’s the original filter (and pump for that matter).
That is…as long as it’s not a later 2003 where they put everything IN the fuel tank…

If Tach doesn’t move during cranking may be a flakey crank sensor or its wiring.
Sounds more like a leaking fuel injector bleeding off fuel pressure, the reason it always starts after the first attempt is because the fuel pressure is normal after the first attempt to start.

Well…I did just have some work done on it. I got the rear main seal replaced and they found a dry rotted PCV hose…so they took the intake manifold off to replace it.
Maybe something happed to one of the fuel injectors then?

Let's get the key position straight first. There are 4 positions in the ignition switch: OFF, ACC, ON, START. If you turn the key to START and you "let the key go" it returns to the ON position.......NOT ACC. If you are turning the key back to ACC this is a manual effort, not automatic. Please cofirm.

Come on man....when you are seeking help always disclose the history.
In any case, if you are going through your key turning routine and it starts EVERY time, then it's unlikely a crank sensor issue. Could it be intermittent?..possible, but not plausible in a repeatable pattern turning the key.
Pull our codes from the DIC.
First step is to check fuel pressure at the rail. Key to ON, pump will run two seconds. Pressure should hold.

Weird starting issue
