2001 Chevy Impala 3.4l v6 140,000 miles
Since my gf got this car about a year ago it as been non stop problems between suspension and everything in between so i will list what may be relevant.I will add them if it may help diag it since it can be multiple issues.
Fuel Gauge sweeping - replaced fuel pump assembly not just the level sensor (after market)
Coolant Gauge not reading at all - replaced thermostat and ECT. Flushed coolant (a/c Delco)
The car has been having two issues i cannot seem to find. There has only been one code for an oil level switch which i replaced from what i researched on it and it was only 8$.
The car randomly will have a long crank/no crank. Cold, hot, long distance, short distance trips.
The car will shutter at stop sign/stop lights or any time the car comes to a stop after driving sometimes or it will shut off after starting to pull away from the stop sometimes. Get a battery light put it in nuetral and it sometimes will start right back up no problem. Possibly same problem ?
So far to try and correct this i have found. . .
Broken PCV hose from pcv to intake boot
Oil level switch fault implausibility i think it was (replaced)
Checked battery voltage and alternator output (both good)
Thinking MAF going bad, vacuum leak and/or crank/cam sensor.
Also has an exhaust leak at the resonator which does not seem to be effecting short term or long term fuel trim. Hopefully some one here has encountered this when they brought there car in to get it serviced or has fixed them at the dealer. Please help need ideas on where to go. I have no codes as of last time i checked last week.

oo yes the the chevy v6 curse lol i know these well. i mostly had every v6 form the 2.8 to the 4.3(350 -2 cylinders). there great motors and will less for ever but just have the crazy problems..... ok lets get started.
1 has the car be in a front end accident or has evident it was bottomed out. i ask this because if it's hit hard it may have messed up the reads on the crank not the sensor but the magnetic pickups on the crank itself. and is the bottom of it covered in oil or does it leak oil at all.
Coolant Gauge not reading at all this was a wiring problem check the wires running form the sensor to the firewall. can be a burn wire. or the cluster itself is messed up
I know this may sound dumb but are u using 5w30 or 10w30 because in my 1999 Chevy lumina if i use 5w30 that light will come on and in my
Corsica if i use 10w30 it will come on. idk why it maybe just that sensitive. a other thing to is sludge when i did my oil pan gasket the sludge was so bad i had to use a paint scarper which broke to get it out.
The
Fuel Gauge sweeping is because for some reason or there's no fuel tank splash guard in the these cars or it broke off or a part of it broke off. or can be a bad ground too
a other question does the car stall when u hold the brake . did it ever stall at idle (not after a drive just starting it in the morning)
no tach as in it don't work or there isn't one in the cluster ?
