05 Chevy cobalt have no power to fuse block for fuel pump


You have no voltage at 15 amp fuel pump fuse in the under hood fuse/relay center ? There is a fuel pump relay also in same under hood fuse box. The fuel pump fuse gets power from the fuel pump relay. The ( PCM ) engine computer controls that relay, gives power or ground electronically to turn the relay on giving power to the fuel pump through the fuel pump fuse. You could have a bad relay or an anti-theft system problem . What engine does you vehicle have 2.0 L or 2.2 L the 2.0 L engine gets power differently to fuel pump .

How many fuel pumps and relays are on a '90 volvo 740 GL


  • You have two fuel pumps. A main fuel pump and an in tank fuel pump and one fuel injection/pump relay that turns the fuel on for the both of them at the same time and each fuel pump has a dedicated fuse.
  • So your vehicle has 1- relay, 2 pumps, 2 fuel pump fuses [1 for each pump ]
  • The relay and both fuses are located under the drivers side of the dash in a little fuse/relay panel.

  • Hope this helps and thank you for using FixYa

Car will turn over but won't start. Through the


No noise from fuel pump when you turn over the car .First thing get voltage at fuel pump relay checked, is there 12 volt to the relay.If no, then problem is again the relay.--------- To reconfirm the problem, try other test, that is remove the relay and by pass the relay terminals with a jumper wire .Then with 12 volt external battery give power to fuel pump connector and see, if the fuel pump starts, then its clear that fuel pump relay is faulty.----------- Also other problem can be fuel pump inertia switch.If the inertia switch is faulty then also fuel pump will not start.-------- The fuel pump relay on a 1995 Ford Explorer is in the power distribution
box, in the engine compartment, driver's side near the firewall.----------
The fuel pump inertia switch is in the right front passenger area
it is below the dash but above the carpet in the right hand corner.--------
Its a push button type inertia switch.
--------
Fuel Pump Activation
When ignition switch is turned to START position, PCM operates fuel pump relay to provide fuel for starting engine. PCM senses engine speed and shuts off fuel pump by opening ground circuit to fuel pump relay when engine stops or engine speed drops to less than 120 RPM. When ignition switch is in ON position, EEC power relay is energized (contacts closed). Power is provided to fuel pump relay and timer in PCM. Fuel pump receives power through fuel pump relay contacts.
Inertia Fuel Shutoff (IFS) Switch
All models use an electrical interrupt switch in fuel system. During a collision or vehicle rollover, electrical contacts within inertia switch open, shutting off fuel supply to electric fuel pump. Fuel supply is interrupted even when engine is running.
A reset button is located on switch assembly. If electrical circuit trips, vehicle will not restart until switch is reset. Fuel system should be inspected before resetting switch.
IFS switch is located under instrument panel, near right side of transmission hump.
----------- If the fuel pump relay, the inertia switch and fuel pump all checked ok, and fuel pump is working with direct 12 volt source to fuel pump.Then problem relates to computer.The computer (power control module, PCM) is faulty and has to be replaced.--------- This will help.Thanks.Helpmech.

Both fuel pump relays run hot. I have replaced both of them. The truck started and ran for about 30 minutes then quit. I replaced the relays and it ran for a few minutes and quit again.


You could have a bad fuel pump relay switch. The fuel pumpmag-glass_10x10.gif relay switch gets the fuel pump running in the vehicle during the start cycle. The terms fuel pump relay and fuel pump relay switch are used interchangeably. The fuel pump relay begins its job when the automobile operator turns to the ignition on, but before the motor is actually running. At that point, the fuel pump relay in some cars sends a signal to the ignition switch, which in turn sends a signal to the fuel pump to turn on. Others fuel pump relays have actual circuitry inside of them that receive the ignition signal and directly signal the fuel pump to engage.

Have a great day!
