SOURCE: My 1995 chevy astro 4.3l will not start. It turns

It sounds like the fusible link,or links have burned into.They are located on the starter itself.They look like a wire,and are bolted on with the positive cable on the starter.To check them,just pull on them ,and they will pull apart like taffy.These are easy to replace,be sure to disconnect the neative cable first.You can purchase these fusible links at a auto parts store.NAPA carys them,i know.They are not expensive either.Do not use regular common everyday wire.You will burn the van down to the ground if there is a short.When you install these,and connect the battery back up look at the fusible link,or links to see that they are not burning back up.Besides a short,these fusible links go out do to hard starts(holding the key to start at low battery voltage.After you replace these links,check or have the battery checked,and the alternator,to see if it is charging enough.If I can help,let me know,this should be the only reason for this to have happened.

SOURCE: how do you change a fuel pump on 2003 chevy astro

on the engine compartment on the fuel rail there is a pressure port that is usually covered by colored plastic cover open it then turn the ignition switch listen for the sound of your fuel pump turning on momentarilly. if you cannot hear it while ignition is on insert small screw driver on the port to open the valve make sure you wrap rugs to control the flow of fuel if there is any. the fuel should around 40-50 psi so expect heavy fuel coming out at port if your pump is working. to change it you have to drop your fuel tank and replace your pump. this is usually left for professional due to fire hazard. any spark due to static electricity can set your fuel to flame up.

How can you check if fuel pump is bad on a 2002 chevy astro


Check your TPS Sensor. My 1995 Chevy Astro Van did the same thing and I thought it was the fuel pump but I was wrong.

1995 chevy astro no spark from coil changed coil and ecm


You may want to try looking at your ignition switch. The ignition switch controls all of the power for the rest of your vehicle, and if the ignition switch is bad it will cause problems like you are having. I hope this helps.

Have no power to the fuel pump on 1995 chevy astro van.4.3


ther isd a fuel pump fuseand fuel pump relay. also and I am not sure where it is located, but all vehicles with electric fuel pumps have a switch that is suposed to cut off the fuel pump if the vehicle get into an accident. this switch on many cars is located on the pasanger side inside car in the kick panel or around the heater box. not sure of location on the astro van. these switches sometimes pop off for no reason or hitting some rough roads etc. Gm also has several service bulitens out for defective harnesses and the problem might be the connector to the fuel pump. some ideas. good luck

I Have a 1995 Chevy Astro with 4.3 engine, that chakes and rattle


the fuel pressure should be 60-66psi so i would start by changing the fuel pressure regulater to get pressure were it should be. to much pressure will bleed past the injector and cause the car to run as you described
