I have seen the airtex become a very reliable pump over the last 10 years i would have little concern using it

Check the fuse under the dash. Did you replace the inline fuel filter? If not, you could loosen the line going into the filter then turn the key to the on position. The pump should run for about 2 seconds then the relay should kick off. Turn off the key for approx. 5 seconds then cycle key back on and the pump should cycle again. If you get a 2 second burst of fuel each time then the pump is cycling. Install a new fuel filter and check the grounded wire by the tank. Hope this helps. :)

yes you have to drop the tank. you will also need a fuel line tool to unhook the fuel lines. before you drop the tank see if tou can reach and wiggle the electrical connection on the top of the tank. these pumps have a pigtail issue. please rate

SOURCE: 2000 Chevy blazer this is the 2nd brand new fuel pump

Spark......EQUIPMENT NEEDED: 1) fuel pressure Gage....Advanced Auto = $45..... 2) needle nose pliers ( fuse pull )..
There is a fuel pressure access valve located on the fuel injector rail. The access port or "shraider" valve has a black or gray screw on cap. Remove the cap and you will see the valve. CAUTION: The fuel rail is under pressure....before installing the pressure gauge, relieve pressure by starting the engine and removing the fuel pump fuse from the under hood fuse box......
Once the engine quits, turn the key to the off position and safely install the pressure gauge. Put a rag around or under the access valve to catch any drizzling fuel. I always prefer to do this when the engine is cool.
Install the pressure gauge, start the engine, check for leaks and read pressure output at idle, record pressure reading.
Also, it should be checked under load but you will need another person to help.
Once you have shut the vehicle off watch the pressure gauge, it should remain steady and not leak down.
Let me know what the readings are.
Regards,

How do you check fuel pressure regulator


If the pressure holds steady than the regulator is likely not the issue. It is very common for the fuel pumps to be the source of this issue. Many times you can start the engines with a shot of carb spray and the engine will continue to run after until you shut it off.

Get a quality fuel pump. Either a delphi or an A/C Delco. These pumps are worth the extra money as they are more reliable than most of the other aftermarket brands. One in particular to stay away from is a brand called Airtex.

2001 jimmy fuel sending unit


if you take the time to drop the fuel tank you might as well replace the fuel pump module. this will come with a new fuel pump and level sending unit. DO NOT USE AN AIRTEX brand. they will leave you with more problems! Get an a/c delco or delphi pump. make sure to replace the fuel filter at the same time.

Is there a fuel relay that could be going bad


The problem is caused by a defective fuel level sending unit inside the gas tank, it is very common and caused by the chemicals in the new cleaner burning motor vehicle fuels eating up the insulator on the sending unit. To replace the sending unit requires the fuel tank be removed, the sending unit is part of the fuel pump module and all are replaced as one unit.

Can I purchase just the fuel pump for a 2003 Chevy Astro van?


No but if you order one from www.rockauto.com you can save yourself about $100.00 cheaper than your local autoparts.I would only get either the Airtex brand,Delphi,Spectra Premium or AC Delco brands any other brand and you're taking a chance of it not working.

Will not stay running but can run as long as you spray the intake with carb cleaner


This year of Chevy truck had problems with burnt fuel pump connectors caused by defective fuel pumps drawing excessive current as they aged. What needs to be done here is to drop the fuel tank out and replace the fuel pump module inside the tank and replace the fuel pump harness connector at the tank connection, both parts are sold at a very good price by a company called "Airtex" as well as many other brands, I have found Airtex to be the best quality of the aftermarket fuel pumps, the factory part is over $350.00

Replaced fuel pump 4 times in 2001 chevy blazer the shop keeps saying the pumps are bad what could cause this


are they buying south of the border pumps from autozone or places like that or are they quality ones like NAPA?
Another reason might be are they installing a new screen sock on the new pump or keep using the original one?
and the last would be if you are running on almost empty all the tome,the gas is what lubes the internal bushings
