I'm "listening" for your results! I just had a tune up a few weeks ago. Now, I'm getting more extended cranks than I ever have. EXACT SAME SCENARIO.
That is actually a tad bit high 58 Psi ± 5 Psi is the standard, but not terrible. And totally possible the gauge is just a bit off.Finally got around to checking fuel pressure. 65psi with key on, stays there at engine start, so fuel pump good.
BUT, pressure drops off quickly after shut down.
Generally the truck starts fine when cold, but has issues when shut off and restarted after 5-10 minutes.
I considered the possibility of a bad fuel regulator, (located within the fuel pump assembly) but it shows none of the symptoms of that, ie; black smoke, fuel out the tailpipe, deceleration issues, not running smoothly or stalling.
However, there is also an anti drainback valve located within the in tank fuel pump assembly, which I believe is the culprit. If the injectors were bleeding fuel into the cylinders that quickly, there would be black smoke upon startup, as well as misfiring due to fouled plugs. New fuel pump assembly is over $200, but if that cures the problem, then that's what I need.
I will update.
Good Morninghi there guys, i have a 2007 nitro r/t,...... in the last couple of months i notice something pretty weird and very annoying. When i first star the nitro in the morning every is normal, it starts normal, all is good for now...., but almost after every ride of more than 30 minutes when i shut it off and start it back on it kept crancking more than usual, and it does it with the remote starter too....,
i have been looking all around for similar problems like this but havent see anything yet....., any help, any info on this pleaseee....!!!!
Thanks to allll!!!
