1998ChevySilveradok1500

Ok so my truck which is a 1998 chevy Silverado k1500 4wd, it has randomly been shutting off on me sometimes, I've replaced pretty much everything for spark such as the ignition control module, the distributor, sparkplugs, spark plug leads, and pretty much everything for fuel such as the fuel pump, the fuel filter which the fuel filter is about 2 months old now, the spider injectors, and along with the coolant temperature sensors ( the one for the ecu and the gauge) and cleaned the mass airflow with mass airflow cleaner and it didn't shut off on me for a while(like 2 weeks) but now its started doing it again. Please please if you have any suggestions all are welcomed

do the lights on the dash stay on? what does the voltage gauge read when it shuts off?

the lights still stay on and it reads at about 9 volts when it does it, and its not throwing a check engine light

get your battery + alternator tested. Battery dealers will have a carbon pile tester for that.

i misspoke. My bad it goes to about the half way mark between 14 and 9 so about 11 or 12 and it is like sputtering before it shuts off, its almost like its choking its self on fuel

mountainmanjoe

still too low

after it shuts off, not while running lol. It stays at 14 when running but once it sputters and turns off its like the key is only in the on position like to turn the radio on and all that

Does it re-start and run ok after it quits?

mountainmanjoe

resting battery voltage should be 12.7V
If yours is 11 as you said then something's not right.

It is pretty easy to start after dying and
i just got a brand new battery and is at 12.7 when in the on position now and at 14 when on but once again on when i drove home it turned off on me again while driving
