2 Answers

2000 chevy blazer 4.3 the problem I have is truck runs very bad on first start up. Push the gas pedal on truck barely moves. Then will smooth out after driving for awhile. If I shut it off and restart after 10 minutes or so same thing. Highway driving is tolerable but I can still tell it's not running real smooth. Fuel mileage is still good

We had this issue with our blazer and it was the mass airflow sensor. We changed it and it has since run fine.

I have a 2006 Suzuki Grand Vitara almost ran out of gas.I put gas in and now when I push the gas pedal the car barely moves I barely got home thepedal


running the pump dry is bad. on all EFI cars
the pump is fuel cooled and fuel lubricated
if you run any pump dry, you risk pump damage
but lets hope it not damaged, hope is good.
key on 10 times, hear it run?(the pump) let it run 10 times not started
and pray it works, and this trick primes it and gets all air out of the line
the 3 second run time is called just that auto prime.
then run it.
never run EFI cars dry, its a rule.
the dash chime told you it was low, ignore that at your risk.

My 94 nissan sentra doesn't run smooth over 3000 rpm or if you mash the gas pedal


I have a 2000 Chevy Tahoe that did the same thing. I changed the oil pump, new oil, and head gasket. It now has power and doesn't fall on its face when I step into the throttle hard. Hope this helps.

2000 chevy blazer is hard to start


The Owner's Manual tells you to NEVER 'pump' the gas pedal, but to s l o w l y ease it to about halfway. Remember its electronically fuel injected, Ace. Sometimes on a hot day it gets overloaded and needs more air.
The cold start sequence involves turning on the switch, then allowing the fuel pump to build up proper pressure.

My 2000 chevy blazer is stuck in 4lo any ideas what the problem is


Try starting the vehicle , place the emergency brake on , switch from drive to nuetral. with engine running try to move the 4wd handle. If your handle moves in and out of 4 wheel drive and the selector handle moves into 2wd you need to drive the vehicle to get it out of 4 wheel low otherwise the 4 wheel drive solenoid may be stuck . This is located on the front axle . round with a vacuum line coming off it. Check the vacuum line at the solenoid or it may be the solenoid. Gook luck with your fix

The plug on the fuel pumps are common for being bad and burning up the pumps. But the new pump will come with a new plug.
