    I know it's an old thread, but I have some great info to add. Took a lot of digging to find the link I've embedded. Have 5 psi and it runs ... kinda. From what I've read, 15 psi is bare minimum and everyone seems to want around 25+. here is a link for a totally awesome TBI troubleshooting guide.http://chevythunder.com/

    (The only way I found the pump problem was to leave the pressure gauge hooked up while driving and keep an eye on it. Occasionally drops to 5 psi but usually about 12 or so).

10 lbs not near enough need to replace pump strainer and fuel filter

Posted on Dec 23, 2008

Could be a clogged fuel filter. How long since you changed it?
It is located bolted to the frame on the drivers side. They only cost $7.00 so I would try this.

MY 1987 CHEVY MONTE CARLO LS ENGINE RACES WHEN START IT UP.IT WON'T STOP TILL, MAYBE 7 0R 8 MINUTES


Two places to start. First clean the throttle body/carb. Brake clean and a tooth brush. Clean inside as best and deep as you can, clean the back of the throttle plate and were it seats the most. It will take a few seconds, start the car up and spray the cleaner in the throttle as you rev it up. Then after that, I would replace the engine coolant sensor.

I have a 99 chevy 2500 van with 5.7 engine.I put new fuel pump,new fuel filter,new fuel pressure regulator,new plugs and wires,new crank shaft sensor,cleaned injectors and throttle body.When I first start...


you forgot the coolant temp sensor, this regulates how much fuel it needs according to temp outside, it can be read with a scan tool, it costs approx 20.00 and make sure they sell you the right one,you don't want the temp sender....You want coolant temp sensor ! In layman terms it's like a choke...more fuel when cold and less fuel when warm.

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

NO FUEL


You might check the fuel pressure regulator to make sure it is allowing fuel to reach the two throttle body injectors and not just stopping at the external ports on the TB.

Sticky throttle on 200 Chevy Astro


There was a recall on the throttle body blade on the 4.3 a few years back for the throttle body to stick in the close position. Yours being 9 years old makes me think that there not going to do anything for it but give you the solution to the sticky throttle blade.
The solution was to change the blade. You can try cleaning the throttle body blade by spraying throttle body cleaner in to the barrel of the throttle body. If you look down, you'll see the carbon build up and it may just need and good cleaning. 
If that does not work, you can buy a new Throttle body blade which is only held on by two screws on the throttle blade shaft.

Start with cleaning the blade and throttle body with throttle body cleaner. Just follow the instruction and you'll be fine. 
Keep me posted and good luck.

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
