1996 Tahoe not running properly. Have installed fuel pump, plugs, wires, distributor, rotary button, etc. It has a dead miss and is flooding. We have tried everything we can think of. It just spits and sputters and will not run correctly.

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?

What is making my 1999 blazer missing and i put spurk pugs and wire,distributor cap ,crack sensor why is it still missing


a faulty ignition module could be the problem. some vehicles have one for the whole system while others have multiples. you can test individual cylinders by first removing the fuel pump relay, then one at a time remove the spark plugs and ground it to the engine block while a helper hits the key. you should clearly be able to see a spark jump across the spark plug. you can also purchase a diagnostic tool which you hold over the wire while a helper turns the key and it reads the current in an inductive manner. if all cylinders are receiving spark then your timing may be out, in some newer (96 and up) vehicles fine tuning of the timing is achieved via ecm in conjunction with the ignition module and cam/crank sensors. in older and a few 96 and up vehicles timing is done solely by the clock position of the distributor. a timing gun can be used to establish correct timing (refer to owners manual/repair manual for proper advancement or retard of ignition timing)



in the event that you have a properly working and timed ignition its most likely you have a burnt valve or dead cylinder, a compression gauge is the best way of diagnosing these issues.



lastly vortec fuel injection systems are finicky about fuel pressure, incorrect fuel pressure will cause the vehicle to run rough,stall ect...most run right around 60psi you can test your system by hooking a test gauge up to your service port.

1999 tahoe intermittent missfire at idle


You could have a plug wire periodically leaking voltage to ground if the wiring is not properly installed, or a problem with your distributor/rotor, but could also be caused by many other sensors (such as a faulty crankshaft sensor) or problems with your fuel system (filter, regulator, etc.).
I would check these plug wires carefully for contact with the engine and good connections at the distributor/plugs, and also add a good quality fuel system cleaner (gas tank additive) before going on with troubleshooting.

I have a 1996 gmc yukon 4x4 have flood problems I have put in new fuel pump has good fuel pressure changed coolant sensors changed throttle body changed computer plugs wires distributor cap and button coil...


Possibly a busted fuel pressure regulator diaphragm. The regulator is mounted to the end of the fuel rail.
With the engine idling, pull the vacuum line off the regulator port. If gas comes out of the port, replace the regulator.

1996 Gmc sonoma


there could be several possibilities, first did you change the fuel filter? most often times a partially plugged fuel filter will cause the sputtering. plugged fuel filters generally lead to the failure of the fuel pump. if you have a fuel injected vehicle the injector themselves can fail, this happens often especially if regular maintenance doesn't happen. i always use an injector cleaner additive when i fill up each time. a common symptom of sputtering is a plugged catalayic converter. the engine needs to breath to run right. also check the airfilter this is important for the engine to breath as well as proper fuel air mixture. if the engine senses a loss of power due to low fuel air mixture it will try to pump more fuel then it should therefore it's basically flooding itself. try these basic fixes first. if this doesn't solve the problem then post back with more detail and i will try a different approach.. please rate this thanks.
