Sounds like you have some a leak some where in the system to where it is letting out the pressure you need to keep the car running i would check fuel pressure regulator and the fuel rails for any kind of damage to them

Fuel pressure specs for gmc sonoma 4.3


2001-2004 gmc sonoma 4.3 [X, W Eng.] fuel system specs: 60-66 psi when you turn the ignition key (fuel pump) on without starting the engine. If fuel pressure drops back down quickly after fuel pump stops working (works for only 5 sec.) then you have a bad fuel pump or leaking injector spider.

2001 chevy blazer turns over but wont run. new fuel pump,new fuel filter,door switch ok,have gas and pressure at manifold, have spark,runs for a second with the help of starting fluid


Try to do the crank relearn:
Ensure that your battery is fully charged before attempting the relearn procedure. Do not leave any battery charger or jumper cables attached to the battery. Close the hood completely. Some applications require that the doors remain closed during the procedure.
96-99 S10
1. Rotate the key to the start position to attempt to start the vehicle (the vehicle will not start).
Allow the key to return to the all position (same as if the vehicle would have started). The theft system light will flash (or stay lit) on the dash for approximately 10 minutes.
2. When the theft system telltale stops flashing (or turns oft) turn the key to the off position for 5 seconds and then attempt tostart the vehicle. The vehicle should start on this cycle.
3. Once the vehicle is running, the password relearn is complete.

1. Rotate the key to the start position to attempt to start the vehicle (the vehicle will not start). Allow the key to return to the on position. (same as if the vehicle would have started)
2. The theft system light will flash (or stay lit) on the dash for approximately 10 minutes.
3. When the theft system telltale stops flashing (or turns off) turn the key to the off position for 5 seconds and then attempt to start the vehicle.
4. Repeat steps 1 through 3 two more times for a total of 3 cycles/30 minutes.
5. On the next cycle of turning the ignition key from off to crank the vehicle should start
6. Once the vehicle is running, the password is learned and this completes the cycle.
7. Clear any DTC's with a scan tool if necessary. DTC history will be cleared after 100 ignition cycles.

Im working on a 95 s10 blazer.It has the 4.3 engine.It will only start if it is sprayed with starting fluid.the fuel pump,fuel filter,and pressure regulator have all been replaced.Seems like the system...


It sounds like the fuel pump is not working. Perhaps the install was not completed correctly. Things to check, fuel pump relay, wiring, voltage to the pump.
The priming happens as soon as you put the key in and turn it to "acc" (you may hear a humming sound). Then once you turn it to "start" the injectors and spark plugs start firing.
Another possibility is that the fuel filter was installed backwards.

Waths the fuel preasure on 99 gmc sierra


  • When the ignition switch is ON and the fuel pump is running, the fuel pressure indicated by the fuel pressure gauge should read 379-427 kPa (55-62 psi) . The spring pressure inside the fuel pressure regulator controls the fuel pressure.
  • A fuel system that drops more than 34 kPa (5 psi) in 10 minutes has a leak
