Have a 2003 F150 5.4l 4x4 with 240k miles. Just purchased for my son so been restoring it the last few weeks. It had an abs light on so I changed the wheel speeds sensors and that just made the abs act up more. My guess was dirt in the hub. So I removed the abs fuse for the last week or so while waiting on wheel hubs to arrive. Last night I changed the wheel hubs and added the fuse back in. Since then the truck takes a bit longer to crank, like maybe theres not enough fuel pressure or something. Its been good the last week without the fuse. Really not sure what would have caused this. Any ideas would be helpful. Every time I fix something it breaks something else. Guess thats what I get with a 20yo truck. Overall though its pretty nice.

All vacuum lines have been smoke tested and most have been replaced. No engine codes.

You're connecting things that are happening to things that probably don't matter. Looks like just a coincidence. If you want to see if fuel pressure is an issue, turn the key on, wait 5 seconds, then turn it off and do it again, several times. That should bring the pressure up to spec. if you have a slow pump or clogged filter.

Has the weather changed over the last few days? Maybe colder temperatures are causing the slow starting.

And, for reference, "crank" is what the starter does, spinning the crankshaft of engine. "Slow crank" would mean the engine is spinning slowly when you turn the key to Start.

"Fire" or start are the words used when the engine begins to run on its own power, after the starter cranks it. The starter should really be called a cranker.

The more you work on a vehicle the more aware you become of its noises, delays, etc.

The two systems, braking and starting are not dependent. Check your fuel pressure, battery and air filter (usual stuff) go from there...
