I have a chevy astro van 1995 motor 4.3 L. The vehicle can not starr. I changed the pump and the gasoline filter and does not start yet. It starts when I spray gasoline directly to the injectors.

Hello! I need to determine if the fuel pump relay is pulling...Do you have a voltmeter? If so set it to read +12 volts ...If you do not have or lack experience with a multimeter, let me know...Locate the Power train Control Module (PCM)...It is above the passenger foot well...see attached diagram...

Connect + meter probe to a safety pin inserted into the rear of PCM connector F pin #6...A Dark Green/White wire...With key on you must read +12 volts...If yes, Fuel Pump Relay is defective...If no...PCM is lacking the proper inputs from one of two sensors...The Manifold Absolute Pressure (MAP) sensor or the Throttle Positioning Sensor (TPS)...Send a comment...Guru...Saailer

I have a 1995 chevy astro van it turns but it won't. Start unlesa you use starting fluid what could it be?


Since it will run on starting fluid, I would guess you have improper fuel supply. Install test gauge to see what fuel pressure you have. Could be bad pump, relay, fuel filter, regulator valve.

1993 Chevy Astro Mini Van not starting


if your mini van has a 4.3 litre engine v6, when you turn the key on you should be able to hear the electric fuel pump start. the fuel pump is inside the gas tank,if you hear the pump you might want to change the fuel filter. The thing about computerized engines and a throttlebody is that you need a fully charged battery to start work with.
