Count the number of times your light blinks, they are codes which indicate problems.

I replaced fuel pump in 1996 tahoe it wont get gas to start


Are you missing anything else, besides gas? Engine cranking, did you check for spark at the plugs and fuel injector pulse? Any applicable trouble codes? Did you check voltage and ground to fuel pump motor, before replacing anything?

Its a 1999 chevy tahoe. Changed fuel pump twice.


Could be the pressure regulator on the fuel rail. Pull the vacuum line off the regulator and check it for fuel contamination. There should not be gas in the line. If there is fuel in that line the regulator is bad and needs replaced.

Chevy tahoe 1999 now it starts but runs for a few seconds then i wait it starts and run for a few seconds again


Seem's like your fuel pump isn't able to keep the good fuel pressure.

Might be a good idea to check your fuel rail pressure. I assume that it drops before your engine dies!!!

If fuel pressure is ok in your rail, try cleaning the fuel rail and injectors. Sometimes dirt can go from a trashed fuel filter an clog yor rail or the injectors.

Chevy tahoe not getting gas to rail


Try a new fuel filter first. From there have someone check the fuel pressure regulator and then the pump. If you are in need of a new pump, take my word for it and spend the money to get one from a Dealer, and not from your favorite parts store. Most parts store parts are made in China and they are JUNK. At least get a OE pump.

My 97 tahoe the rpm's start going funny engine startes running like its missing popping and ******* and die's it has new fuel pump ,sending unit ,rotor,cap.cam censor ,fuel relay everytime i c


I'm assuming you replaced the fuel filter when you did the pump.
You'll have to try to figure out if you are loosing fuel to the injectors or spark to the plugs to proceed.
Its possible something is failing inside the distributor among other things.
I'm also assuming you have checked the computer for trouble codes.

98 tahoe has new starter, new fuel pump, new alternator, and does not start the battery is also new. what should i do next?


Check if there is spark to each cylinder. If not, check crank shaft position sensor if no spark at all. If spark in some cylinders but not all, then check coil packs.

If spark is good, check that you have sufficient fuel pressure. You can use a fuel pressure tester or place a rag over the fuel pressure test port on the fuel rail, press in on the valve and see if there is pressure in the fuel rail. A tester would be more accurate.

Is there a huel reset on 2001 chevy tahoe


Sorry there is no fuel pump reset on the Tahoe. If you have no fuel pressure, check the fuses and relay,and wire harness to the fuel pump from the inside frame rail on the drivers side. If you can hear the fuel pump working, check the fuel pressure at the shredder valve and there should be 60 to 66 PSI, if you don't you can try checking for 12 volt at the fuel pump wire harness at the frame rail. Good luck and keep me posted, be glad to help.
