Have a1998 astro van that wont start until I spray starting fluid in the throttle body, then starts up and runs fine until about two hours later I go to start it back up and it wont start again.PLEASE HELP...


The first thing you need to check is fuel pressure. This type of fuel system requires a minimum fuel pressure of 56 psi to start. Anything less, even as little as 1psi. And it will not start. It starts and runs when you add the starting fluid because the poppets (the mechanical injectors located at each cylinders intake runner) require less fuel pressure to operate when the intake is under vacuum.

This is a classic symptom of low fuel pressure. A new fuel pump is the typical fix for this problem. Don't skimp on quality if you do need a new fuel pump. They are not all the same.

1993 astro van wont start when van has been sitting for awhile. spray intake clean into throttle body and van starts and runs.


depends how long its been sitting if starts with easy start then its a fuel pump problem like the fuel has gone bad or the pump has gummed itself up ,so take it out and check that the pump still works as i suspect that its gummed up and good clean will cure it for you

1999 chevy tahoe wont start and if it does it dyes rite away


That sounds like a fuel pump problem and you can test that by pulling a vacuum line off from the intake manifold and spray a lot of carburetor spray or brake cleaner in a spray can into the intake manifold through the open vacuum line port (it has to say "extremely flammable" on the can to work and the non-flammable will not work for this test) and then replace the vacuum line and see if the engine will start and run for a few seconds on the spray.

If the engine does start and run then the problem will most likely be the fuel pump, however a faulty ignition module inside of the distributor could keep the fuel pump from running or the fuel injectors from firing and if there is good fuel pressure in the fuel rail, (there should be a schrader valve in the fuel rail for testing) and there is spark out to the spark plugs but the engine still will not start, then the ignition module inside of the distributor would be the likely suspect of the problem.

If the engine does not start then you will need to determine why there is no spark to the spark plugs, and most likely the problem will be the ignition coil or the ignition module inside of the distributor, or there could also be a problem with the ECM (Engine Control Module).

2005 no start astro van how to check if fuel pump is bad.


Open the hood ,remove the air box for the engine but leave the mass air flow sensor on.Get some carb cleaner and spray it in the air intake tube while someone tries to start the van and if it fires and runs on the cleaner it is defanetly a fuel issue and most likely the fuel pump.If you have a fuel pressure gague you can remove the engine cover inside the van and connect to the fuel pressure port to see what u have for fuel pressure which should be between 55-65 psi to run.

Chevy astro van turns over but wont start when


Check to see if the fuel pump is kicking in,
when you turn the key on without starting the van you should hear it kick on for about 2 seconds,

It could be...
A clogged fuel filter...
Blown fuse for the pump..or bad pump relay..
No gas
Bad fuel pump

underneth the intake manold is were your fuel injector poppet nozzles are, more than likely the fuel line hose that goes thru the back of the intake is split and leaking fuel underneth the intake manifold if you check the fuel pressure you will find that the fuel pressure will drop down to 0 psi as soon as the fuel pump shuts off and it should hold pressure
