SOURCE: 1998 Chevy tahoe Hard to start when cold

Hello, yes the check valve is in the fuel pump assembly. The check valve is leaking and the pump will burn out soon. Unfortunately the aftermarket fuel pumps can be very unreliable. A good portion of problems we see on this site are from people who replace the pump sometimes twice and it still doesn't work.

replace your MAP sensor(manifold absolute pressure) the map sensor is the computer for your fuel pressure regulator telling how much pressure. Unless your tahoe runs like **** going up hill than it inevitably your fuel pump

the very 1st thing u do is have the trouble code checked that turned on the light, there are well over 200 possible reasons for a check engine light, a fuel filter is not one of them.

SOURCE: 2001 grand prix starts and then dies right away

Check the fuel pump inline resistor located on the right side front fender between the frame and the windshield washer fluid canister. When this resistor goes bad those are the symptoms.

Got 2002 grand prix driving just died i replaced fuel filter fuel pump cleaned all sencers still wont sty running what can i do

Did you check to see if it has spark at the plug wires ? Possible crankshaft position sensor ! Are the fuel injectors being commanded on by the PCM ? Did you check for fuel pressure with a fuel pressure gauge ? Just because you hear fuel pump running does not mean fuel is getting to the injectors ! Did you have the engine sensors data checked with a scan tool ? Mass air flow sensor !

I have a 2004 grand am. the motor turns over but wont start. I changed the fuel pump, the ignition is good, fuses are all good but it will not start

first check the fuel filter. check before and after the filter if you get fuel before it then check after it, no fuel before go back to the pump. if you get fuel after then go to the fuel rail on the motor. open the line before the pressure regulator, if you get fuel then check after the regulator, if none after then the regulator is bad, if the regulator is vacuum assisted check your vacuum.

1998 Pontiac Grand Prix GTP Starts and turns off approx 5-10 seconds after starting.

I would replace the TPS sensor. If you have fuel pressure enough to start the car, then you probably have pressure always. Before turning the key to start, turn to ON. You should hear the fuel pump pressurizing the lines. Turn the car back off. Go under the hood and remove the cap to the Schrader Valve. Use a rag to catch any fuel when you depress the valve stem. If fuel comes out into your rag, you should have pressure. Try this a second time to be sure. I had this issue with my car shutting down. TPS sensor replacement fixed it. could be vacuum lines, or another sensor fault. The TPS is a common issue. You may also want to clean your Mass Air Flow sensor with the proper solvent and technique.

1989 grand prix starts and will idle but dies when i step on the accelator

Try a new gas filter and have the fuel pressure checked. Scan the engine computer for trouble codes. Check your air filter and replace if dirty or old. How old are your spark plugs, need new ones?
Maybe it just needs a tune up.

Check the fuel pressure regulator. Pull off the vac line to it and see if any gas is leaking out of the vacuum fitting. If you see any fuel replace the regulator.
