when you first try getting fuel going. you may have to turn the key on and off a few times to build up pressure. if you can hear the pump working it will change when it builds up pressure. if its not then I would say you have a line leaking. check all your connections before you have a fire

1997 blazer has spark, new cam sensor, fuel filter..will crack over, but will not start. I tried starter fluid in the intake, and still does not start. any ideas?


Fuel pressure regulator probabaly flooding it when you turn the key forward it primes but the regulator just dumps to much fuel into the cylinders flooding the plugs pull a plug out after you try starting it if it dont start and see if there full of gas

THE INJECTORS WILL NOT SPRAY I PUT IN A NEW FUEL PUMP IT CRANKS AND FOR FIVE MINUTES AND WILL NOT WORK ANY MORE AND NEW GAS FILTER, NEW CRANK SENOR CAM SENOR


Did you also replace the fuel filter If so it may be the fuel regulator thats inside the plum on top fof the intake manifold i see you did do the filter I would suppect the regulator before the injectors you have done most of the hard and expensive stuff already If one injector was giveing you aproblem ok but not all of them at once also make sure the pump is putting out before you start anything else sometimes its a wireing issue with the pump

87 s 10 well not run it is not getting gas to the injected


Make sure fuel pump is cylcing,you sould hear pump when you turn key on. Check fuel filter and relay for fuel pump. If still won't start try banging tank hard 4 or 5 times with key on and see if you hear pump cycle.If that works fuel pump needs replacement. Also try pouring some gas in intake to see if it fires up.

CAR WONT START


If the car fired after pouring gas into the engine, then you should check your fuel pump, listen when you turn on the key, if you hear the fuel pump start and stop, then check your fuel pressure, all fuel injected vehicles have fuel pressure regulators, if your fuel pump isnt pushing enough pressure to the regulator the car will not start, and if it does start it wont operate properly, and may even leave you stranded.. If your fuel pressure is low, check the fuel filter, dirty filters restrict pressure, and are ALOT cheeper to replace than a fuel pump!

99 blazer, cranks but no start, pour gas in intake and it starts


well if its a 1999, it wont have a carb, it has fuel injection.take your fuel filter off and clean it or put a new on one, that should fix the problem. check your hoses too.

1999 chevy silverado 5.7L 2wd truck would not start, could not hear the fuel pump, lifted truck bed and cked pump, i have power to pump, it appears that the fuel pump relay is working like it should, power...


did you check the fuel pressure? there is a sharder valve on the fuel rail to do this. i know you have to have a certain amount of pressure in order for it to run.i think on fuel injection its around 60 to 70 psi.and on throtle body is around 30 to50.psi. i also know if you run your truck low on fuel alot it will burn up the pump gas is what keeps pump cool. also you said you found a pluged filter witch over time will burn up the pump. hope this helps.
