We have a 2001 Jimmy GMC. Is there a way to see if the air pump is bad? Keep getting 410 code. It won't pass emissions?

Code 410 for a GM product is a problem with the secondary air injection system.
There is a pump that puts air into the exhaust to lower emissions.
You may have to get a shop manual to find the diagnostic steps to find the problem.

I will suggest if you ever drive it to California, unless you comply with their rules it won't be legal. However if you're a legal resident in another state, abide by their rules u should be ok. Again this is not legal advice, it's a suggestion.

i have a 1994 gmc jimmy 4.3l cpi. i could not pass the emission test.hard to start, spuddered, and smell of gas was strong. long story short, i replaced my spider injectors, good to go. $278 brand new from auto zone.

Code 410 is not a Trans. code it is a secondary air injection system problem that is why you have a high idle , it is probably the valve , but it could also be the pump which is located behind the bumper .....

PO 301 is no 1 cylinder misfire, PO 410 is secondary air injection system, & PO 442 is Medium leak detected in EVAP system.

P1416 - Secondary Air Injection (AIR) system Bank 2
1416 means that you are running lean while the smog pump is on.
It could also be likely the vacswitch on the smog pump is the causes.

give autozone the codes and they will give yoy a print out a list of what will cause it or get a repare manual it will save you money in the long run, bobg22

I don't think you have anything wrong, I just don't think you have completed the correct drive cycle yet. Some vehicles must be driven in a very specific way before all the monitors will set. Here is the drive cycle that Gm Recommends:

1. Cold Start. In order to be classified as a cold start the engine coolant temperature must be below 122°F (50°C) and within 11°F (6°C) of the ambient air temperature at startup.
   Do not leave the key in prior to the cold start or the heated oxygen sensor diagnostic may not run.
   
2. Idle. The engine must be run for two and a half minutes with the air conditioner on and rear defroster on. The more electrical load you can apply the better. This will test the O2 heater, Passive Air, Purge "No Flow", Misfire, and - if closed loop is achieved- Fuel Trim.
   
3. Accelerate. Turn off the air conditioner and all the other loads and apply half throttle until 55mph (88km/hr) is reached. During this time the Misfire, Fuel Trim, and Purge Flow diagnostics will be performed.
   
4. Hold Steady Speed. Hold a steady speed of 55mph (88km/hr) for 3 minutes. During this time the O2 response, air Intrusive, EGR, Purge, Misfire, and Fuel Trim diagnostics will be performed.
   
5. Decelerate. Let off the accelerator pedal. Do not shift, touch the brake or clutch. It is important to let the vehicle coast along gradually slowing down to 20 mph (32km/hr). During this time the EGR, Purge and Fuel Trim diagnostics will be performed.
   
6. Accelerate. Accelerate at 3/4 throttle until 55-60mph (88-96 km/hr). This will perform the same diagnostics as in step 3.
   
7. Hold Steady Speed. Hold a steady speed of 55mph (88km/hr) for five minutes. During this time, in addition to the diagnostics performed in step 4, the catalyst monitor diagnostics will be performed. If the catalyst is marginal or the battery has been disconnected, it may take 5 complete driving cycles to determine the state of the catalyst.
   
8. Decelerate. This will perform the same diagnostics as in step 5. Again, don't press the clutch or brakes or shift gears.

air pump on the lower passenger front under shield and mounted to frame is bad they get water in them and lock up need new one

What does that mean? The P0410 code refers to the emissions system. The AIR pump puts air to the exhaust to lower emissions. It takes in outside air and pumps it through two one-way check valves into each bank of the exhaust.
About 90% of the time that this code is set, the one-way check valves have worn out or failed and allow water (which occurs naturally in the exhaust) back into the pump. In any cold climate, especially in climates with higher humidity, this water may be more excessive. The water partially fills the AIR pump, it can then freeze. When the PCM commands the pump on, if the pump is frozen it cannot turn, thus overloading the circuit and "popping" the fuse.
Symptoms Possibly symptoms include:

• MIL illumination obviously
• Hesitation on acceleration
• Noise from a bad/stuck AIR pump

Causes A code P0410 may mean that one or more of the following has happened:

• Water may have collected in the AIR pump or the vent solenoid and frozen or corroded the pump
• Blown AIR pump fuse due to freezing up

Possible Solutions Note: There is a technical service bulletin (TSB) regarding this code for a number of GM models. The TSB calls for the replacement of the AIR pump and the installation of a new secondary injection hose. The TSB can be found on this ACDelco site.
Additionally, if you simply replace the AIR pump the problem may return again (and again). If you replace the pump, also clean out the hoses and replace the one-way check valve. If this is on a GM model that the TSB applies to, follow those instructions in the link above. In a few cases, people have put a small hole in the rubber cover on the pump which allows any water to drain out.
Also, please note that this may be covered under the emissions warranty on the vehicle. If your vehicle is out of bumper-to-bumper warranty, check if the emissions warranty is still valid!

• Replace the AIR pump AND one-way check valve
• Test and clean the AIR pump AND test and replace the one-way air check valve
• Replace the AIR pump inlet hose
• Replace the AIR pump fuse (found under the hood)
