If the code is p0410, it is the secondary air pump. It tends to fill with condensation and fail. Replace the pump and check valves coming off the manifold on either side of the engine. The driver's side check valve seems to fail first and allows condensation to run down hose to pump. Hope this helps.

Engine won t shut off


Poor ignition switch .Replace it and check for the blown fuses & your problem will disappear .As ignition controls the current to ECU so if the ignition will still be transmitting the voltage to ecu with the key turned off so how will a engine shutoff? think it's logical.You have been tricked by mechanic as it's not the computer fault at all.

1999 2door blazer installed new fuel pump 60psi when tested won't start dump gas in intake starts and shuts off ??????


Sounds like your injectors aren't opening if it holds that pressure. Get a "noid light" at parts store that fits your injector harness connection (just a few bucks). Just pull connector off injector and plug in noid light. When you crank engine, the light should blink rapidly. Try all of them, or at least one on each bank (side).
If light doesn't blink, then check your injector electrical circuit. Power to them is fed through your ignition switch, and the ecm grounds that particular injector at proper time to make injector work.

SOMTIMES POUNDING UNDER CENTER OF GAS TANK WHILE CRANKING WILL GET IT STARTED AGAIN BUT THIS WILL ONLY WORK ONCE OR TWICE GET IT TO A GARAGE OR SHOP TO GET IT CHANGE IF THIS STARTS IT UP

I would like to reset or disconnect my check engine line on 1999 chevy blazer. The vehicle runs fine and I don't want to pay for it. How can I do this ?


The check engine light is there to tell you that someting is wrong.
Yes the car "seems" to run fine, yet is most likely using more gas, and if you ignore this to long can cause a lot of harm and a lot of $$$.
Have it fixed at some point soon.
And you can't disconnect it.
