If the punp is bad it won't run at all. Check the throttle body injectors to see if fuel is coming out of both injectors. Sounds like one of the injectors is not working. If one is not working you can check to see if it is the injector or wiring by switching injector wires and see if the problem changed from one injector to the other.

Why when i poor gas in carb it runs and then a few mins later dies


Test the fuel pressure, if it's low or non existant, you have a bad fuel pump, fuel pump regulator, or clogged fuel filter. That car has a throttle body, not a carburetor. All fuel injected cars have throttle bodies

General advice:After warming up track the problem:sparkplugs (even new can have the ceramic parts broken/cracked /wiring (after warming up the isolation get's soft,can loose spark power)/ignition coil(s) (gets hot,stop runnig),running reach,fuel pump/fuel pump relay.Best guess:fuel pump mallfunction (low pressure) related,fuel filter cloged/water in the fuel/fuel line cloged/chipped. Cheers,hope u figure it out,let the people know.

1987 chevy with Throttle Body... You literally have to put it to the floor to get it to start, then it'll run nice for a while thinking it'll run take it for a drive and it will shortly die on


Check all fuel lines for leaks, make sure it doesn't have bad gas in it. Listen for fuel pump when key is turned on. Change fuel filter. See if that's helps.

Sounds like the fuel pump is going bad(or in this case,has gone bad). I suggest that you change the fuel pump and use a fuel cleaner in your gas tank as dirty gas may have caused the problem to begin with.

It ran out of gas and now wont start. I put gas directly into throttle body, and it starts/runs, but wont remain started when gas runs out.


Sounds like fuel pump. Your fuel pump relies on fuel to act as coolant. Running it low often makes pump run hot and shortens it's life. Sounds like running out of fuel did just that. Way to test, pull fuel line off in engine compartment and have someone turn key to "ON" (NOT START!!!) position, you should fuel spraying out of line) If not, fuel pump is bad.

88 firebird doesn't get fuel, I replaced the fuel pump and did a test run and it works, I also replace the fuel pump relay, and Im still not getting fuel.


I would check the fuel pressure regulator, fuel filter, there might be a centrifugal cut-off switch. No output from the crankshaft position sensor would probly cause that. When you turn the key on you should be able to hear the pump run for a couple seconds. If not, could be a short circuit, loose connection, that sorta thing.

Fuel filter cloged up and stopped running. changed filter and now running rough truck has 210070 milles always ran great untill filter cloged any tips


Most of the time,when the fuel filter stops up,it puts a strain on the fuel pump,and the fuel pump gets weak from trying to run,and most likely in your case this has happened.You will have to replace the pump,to fix the problem,but have the fuel pressure test done just to make sure,if this was helpful,please rate,and thank you.

Ran out of gas. vehicle started, ran, drove home,


the fuel pump runs for 5 seconds when you turn key to ON. It runs all the time whie cranking and after engine starts.

Spray some starting fluid into throttle body & see if it starts then. If yes, pump may be bad. Can you hear pump run in fuel tank?
