My car keeps dieing usually when I am going 35 to 40 mph and it's hard to restart sometimes after it does it

Question

2001 chey montecarlo SS

I pulled up 3 codes on the obd2 codes they are po 336 po 327 po332

Answer 1

i have worked on many gm vehicles since I went to school to be a GM certified mechanic. I would gues that you may have a bad ground on you ignition somewhere or the fuel pump. Alot of times when this happens the rattleing of the engine while trying to start will move the ground wire enough to make contact again and start and then after sometime no specific amount could be 2 seconds or hours depends on luck it will move and kill the car or at the very leasst shut down the part of the vehicle it was being used for. Could be on the supply side of the wire also.

After getting on the internet and looking at what these codes are I would look at the crank sensor. the first code os for this the other two are for the knock sensors. A bad crank sensor could cause the other codes to set. Chek your wiring to make sure you do not have a bare wire or corroded terminals. also the wires going toe this sensor should be twisted to prevent radio waves from distorting the signal generated by the sensor.

Even though after researching it the crank sensor or circuit is the problem area my other answer are still very plausible.

Answer 2

pull your codes. buy a code reader, or take it to the autozone or whatever and ask them to do

the only thing i can think of is a fuel problem, where your car is being starved of fuel it needs and won't start after because it doesn't have enough pressure for the injectors to function properly. most modern fuel injection cars need around 40psi

when it won't start try priming the fuel pump. turn the key into the on position and off again a few times. just as far before the part where you turn to actually start the car. this just turns the car on so you can listen to the radio and stuff. it also primes the electronic fuel pump, you'll usually hear a whirring and a click noise from the fuel tank area. do this 3 or 4 times, just to make that pump go on and off a few times and build up your fuel pressure and then see if it starts.

to properly test this you need to put a fuel pressure guage (about 30 bucks) on the fuel rail and turn the key on and see wtha the fuel pressure is, to determine if you have a fuel deliver problem.

Answer 3

Check the electronic brain. I had a Monte Carlo SS and that happened to me. It's not real expensive to replace. It beats going down the road and dying every few feet.

Answer 4

Take it to a mechanic. It may just be a vacuum leak, or something else that is simple to fix, but hard to find.

Answer 5

Do you keep up maintenance? A friend of mine had the same problem, and it turns out he never changed his air filter. Ever.

Answer 6

could be fuel filter,try that first its the cheapest way to go, as for starting hard that sounds like ultinator or starter getting weak, pretty smart for a woman huh, hope it turns out for ya.

Answer 7

Gotta take it to a dealer who can do a diagnostic test.
