I have a 2001 impala ls it wouldnt star one day i bought it to a mechanic they changed the fuel filter and told me im gonna need a fuel pump it started for one day so i got a fuel pump put in it it still wouldnt start da new battery dat was in it is completly dead the car is making sum funny noises in the car and tumping noises thru the speakers...

Change your fuel filter

ck fuel press,poss.vacuum leak at intake manifold

Usually valve body is stuck,flush?did they change trans fluid and filter if not recommended you change filter and a bottle trans x it helped a 2001 impala ls I had transmission was good till the day sold it

well i dont think changing the fuel filter will fix whats wrong but the filter should be under the car under the door hooked to the gas line

This is a complex problem.

Do you have any repair record of the Rodeo LS?

When is the last


ignition module change?

fuel pump change?

fuel filter change?

DO YOU TOP OFF during gas refuel?
DO NOT DO IT

Are you able to get the OBD-II codes off the ECU?

=======

I will check fuel rail pressure first to rule out the fuel pump

add Chervon fuel injector clear and fill gas to above 1/2 tank

locate the ignition module and apply GOOD amount of white lithium grease to help it from over heat.

When the truck stall again check the temperature of gauage......Engine should be below 195F

Let the module cool and see does it ran well again.



Good luck

check your fuel filter. If it is plugged replace it. A plugged fuel filter can cause a fuel pump to have to work too hard & cause it to burn out prematurely

its the camshaft position sensor . Its located (atleast on my 1.6L) to the right of the front HOT plate the conection runs between the engine and the right side fan. easier to work on if you take off the air intake thats by the left front side of the battery. you will be working between the fan and the motor. only one bolt but is tricky so u need a 1/4 inch nuckle with a 1/4 extention. once located and you have the right tools it will only take 30 minutes to replace....dont forget to take off negative battery cable before you start.

Had the same problem awhile back i changed the whole sending unit and also i was told that your computer has something to do with the fuel pump.

My car has a similar problem, if you take it to AutoZone or Advance Auto Parts they will usually scan it for codes at no charge. My problem is a bad Map Sensor. Hope this helps.

make sure to check for and aftermarket ignition module installation in other words make sure the ignition module is factory and not aftermarket,
this is not a fuel problem because fuel problem acts diferent
but coul be your ignition module or your crank sensor
