So it's not a big deal but something I've been wondering about.
I've watched quite a few videos on YouTube, mainly looking for videos on exhaust, but that led me to listen at how quickly most T-Birds start up.
I noticed that my Bird takes longer to crank than pretty much every Bird on there. When the car is warm and has been running lately it's not bad, but when it's sat overnight it takes a few seconds of cranking.
I'll try to get a video of the startup time one of these mornings and you can give me your opinions
So I figured I'd check the fuel pressure. I hooked up the gauge to the rail, and turned the key on (not start) 3 times, pressure built up to 36 psi which is good.
I let it sit and after 5 minutes it was down to 34 psi, after 10 minutes it was down to 31 psi, and after 15 minutes it was down to 30 psi. I forgot to leave the gauge on and check the pressure while running.
Now I'm not a mechanic but that's obviously a bit of pressure drop, is that enough drop to be concerned? I know too much drop can mean I have a leaky injector or other problems.
One thing I did recently was run a can of seafoam through the tank. I was thinking that if it was a case of dirty injectors that should help. The car seemed to start better a few times after I dumped it in the tank but was back to normal by halfway through the tank.
Now, it's not a big deal because the car always starts, but I'm just curious if there's anything else I should check on. I'm thinking I'm either looking at a new fuel pump or new/rebuilt injectors if I really want to pursue the issue.
