So, randomly while working on a customers car. i needed to check their fuel pressure, wasnt getting a reading on my gauge despite some visible (but small) pressure so i wanted to double check my gauge and get a control. so i hooked it up to my truck and it was 20 PSI KOEO and KOER. which is waaay below spec.
ive had teh truck for years, practically rebuilt the whole thing but the bottom end. its in good running shape, it doesnt idle bad, doesnt run bad, its not a power house either, lifted, big tires, small gear ratio, i dont expect it to chirp the tires, but i mean its always felt sluggish, but acceptably.
The only odd things that have ever happened, is during the colder months, when i crank it, it will start then stall immediately and the start back up right away on the second crank, everytime without doubt for years. just how she is.
and occasionally, she'll stumble a bit and rpm drop down for no reason every other month.
i can rev it all the way to the limiter in every gear (if i had enough time and space in 4th and 5th hahaha) never bogs down.
i guess the only other things that comes to mind is, but i cant find any info on the spec for it. the engine runs at 13-15 inHg vacuum. which always has, no vacuum leaks, 160 PSI compression in every cylinder. so i never thought twice about it.
Anyways... my point
Im all paranoid now that i saw 20 PSI, and wondering if my truck has been starving for gas for ages, no lean codes. im tempted to just go buy a new fuel pump anyways to see if my engine will come to life (lol doubtful)
or should i just leave it alone, if it aint broke dont fix it?
and any info on the vacuum pressure spec would (or what yours is) be nice too.
cheers mate
