Question about 2000 Chevrolet Astro

1 Answer

Fuel pump will not kick on, I replaced it with a brand new one and still nothing. I checked the fuel pump relay and Ignition control module and both were good. I ran power straight to the harness on the fuel pump side and it turned on. I'm clueless as to what it might be next. =(

My 93 cougar like sputters when running. no power, and idles real hard. what could this be?


I'm guessing fuel pump is going. Check for 40 PSI pressure with fuel pressure gauge. Check in engine comaprtment.
Section 10-01: Fuel Tank, Filters, Lines and Electric Fuel Pump 1995 Thunderbird, Cougar Workshop Manual
DESCRIPTION AND OPERATION Fuel Pump, Electric The electric fuel pump:
  • Is part of the fuel pump module.
  • Is located in an internal reservoir in the polyethylene fuel tank (9002) .
  • Is mounted with its inlet at the bottom of the reservoir.
  • Is designed to increase satisfactory pump operation during extreme vehicle maneuvers and steep climbs with low fuel levels.
  • The high-pressure fuel pump module on the 3.8L SFI and 4.6L-2V engines can supply 60 liters (15.9 gal) of fuel per hour at a working pressure of 269.0 kPa (39 psi).
  • The fuel pump module on the 3.8L SC SFI engine can supply 125 liters (29.0 gal) at the same rate and pressure.
  • The fuel pump module has an internal check valve to maintain pressure in the system after the engine is shut down.
  • The fuel pump module also has an internal release valve to provide protection from too much pressure if fuel flow becomes clogged in the fuel filter (9155) , the fuel line is damaged, or other factors.
  • Overpressure is limited to 850 kPa (123 psi) and reduced fuel flow will result if the pressure relief valve is activated.
  • The fuel pump module is protected at its inlet by a nylon fuel filter element (9365) which filters contaminants which could plug or damage fuel pump components.
  • The fuel filter element simultaneously allows passage of small quantities of water which may accumulate within the tank reservoir.
  • The electrical system has a fuel pump control relay in the powertrain control module (PCM) (12A650) which provides power to the fuel pump module through an inertia fuel shutoff switch (IFS switch) (9341) that is normally closed.
  • The electrical system provides power to the fuel pump module through two relays:
    • Fuel pump power relay.
    • PCM power relay.
The current path depends on operating conditions.
  • When the ignition switch (11572) is OFF, contacts of both relays are open.
  • When the ignition switch is first turned to RUN, the PCM power relay energizes and closes its contacts.
  • Power is sent to the fuel pump relay and a timing device in the powertrain control module .
  • The fuel pump module runs through the contacts of the fuel pump relay.
  • If ignition switch is not turned to START, the timing device in the powertrain control module will open ground Circuit 57 after about a second.
  • Opening the ground circuit deenergizes the fuel pump relay, which opens its contacts and de-energizes the fuel pump.
  • The circuitry provides pre-pressurization of the fuel system.
  • When the ignition switch is turned to START, the powertrain control module operates the fuel pump relay to provide fuel while cranking.
  • After the engine starts and the ignition switch is ON, power to the fuel pump module is again supplied through the fuel pump relay. The powertrain control module senses engine speed and shuts the fuel pump module OFF by opening the ground circuit to the fuel pump relay when the engine stops or is below 120 rpm.

Replace egr valve still wont start


PROBLEM COULD BE FAULTY FUEL PUMP OR IGNITION MODULE.CHECK FUEL PRESSURE SHOULD BE 41 - 47 PSI. IF NO FUEL PRESSURE TO LOW REPLACE FUEL FILTER.STILL LOW FUEL PUMP FAULTY.IF FUEL PUMP DONT RUN CHECK FUSE AND RELAY.IF FUSE RELAY GOOD PUMP BAD.IF FUEL SYSTEM OKAY USE A SPARK TESTER TO CHECK FOR SPARK AT SPARK PLUGS IF NOT CHECK IGNITION MODULE FUSE IF OKAY IGNITION MODULE COULD BE BAD.USE A CODE SCANNER TO CHECK FOR FAULT CODE IN PCM AND IGNITION MODULE.THIS SAVE YOU FROM SPENDING TOO MUCH MONEY.

Won't run. Replaced Fuel Pressure Regulator; Engine Computer Module (QDM40; sprayed carb cleanet into EGR; replaced Ignition Control Module. Car runs on Quick Start Fluid only.


If it runs on start fluid and nothing else its obviously a fuel concern fuel pump ,fuel pump relay ,check fuel pressure at the regulator that you replaced.

I have a 91 s-10 that wont run...fuel pump runs and I am getting fuel to the carb all brand new plugs and wires and ignition coil and module and new cap and rotor? fires up and dies out?


The fuel pump relay is at fault. The engine will start running off the oil pressure sensor for the 3rd wire connected to the sensor feeds power to the fuel pump which makes your truck start right up. When the engine achomplish the standard oil pressure as needed the sensor shuts power off by the PCM default system and turns on the fuel pump relay to continue working the fuel pump. replace the relay and you will be driving around again

The fuel pump relay is burried under the dash. The new one will help you find the old one. It is bigger than e regular relay.
It is on the drivers side Ithink.
If you don't hear the pump when you turn the key it will never start. All of those relays fail because these cars outlast them.
