2002 f150 starting

so my 2002 f150 5.4l runs great! but soetimes when i start it, it cranks-then pauses- then starts. and idk what it is theres no codes?

also sometimes it will start and it feels like the engine shakes then starts

plugs just changed, oil just changed, and 150,000 miles runs amazing

 

Battery might be a bit weak maybe for the pause, otherwise its a big V8 that takes a lot to crank over. What type oil are you running?



Welcome by the way!

 

Starter or solinoid

 

Sounds like a solenoid since it seems that the starter itself really isn't having a problem....I had to replace the solenoid on my 2000 F150 when I had it.

 

I'd start with the solenoid. It's cheaper than a starter.

 

I think were all on the same page

 

wow thanks for the quick replies! compared to f150forum lol and thanks for the welcoming. i did do a test at school and it said my starters god but my battery is weak (10years old). so im gonna try a solenoid first. is there a how to for changing it?

 

Time for a new battery

Selenoid is an easy swap but I don't believe we have a write up on it. Let me see what I can find from my phone otherwise I will be on my computer later

 

alright now what about the engine shaking when it starts (sometimes) could this be cause the battery is not cranking fast/hard enough so it starts very poorly?
