If you are buying after-market fuel pumps this could be the problem. I replaced the fuel pump in my 96-350 with an after-market and it only lasted a year. The pumps from the dealer are more expensive but worth it. I just installed my 4th fuel pump, an after market for $150. The first 3 were original from the dealer, a $475touch plus labour. This seem to be a common problem with others I have talked to. My last pump was installed 15 months ago at the GM dealer, 3 months past my 1 year warranty. We always kept the fuel tank at least 1/4 fuel so the pump was immersed and wouldn't heat up but that didn't seem to help. Good luck. 4 4
to reset an injector , is a specialist job if injector is faulty, it needs replacing
can i change 1 fuel injector on 4.3 6 cylinder silverado 2003.
it has throttle boddy
The 1996 Chevrolet Silverado no longer came with throttle body fuel injection. It probably has the central sequential fuel injection system (CSFI) where each cylinder has its own fuel injector.
No it is not a fuel pump problem. It either has a grounded are open circurt. Check wiring to injector. May just be a bad INJECTOR.
Are you sure you are changing injector #7? Should be the injector closest to the firewall on the drivers side. If you are changing the correct injector, and the code remains, the problem is with the wiring from the injector to the pcm (computer) or the computer itself. You can check for correct battery voltage at the injector with a volt/ohm meter (how does the connector look at the injector?). This year of Durango/Dakota had trouble with computers too, although I have not heard of specific injector trouble being caused by the computer. Most likely a wiring problem. It may even be the TPS
If it's running like it's supposed to, there's no need to replace it. I have an 87 Silverado, and it's never had the injectors replaced.
check plugs, wires, or coil packs. on cylinder #5. But if your changing plugs or wires do them all at one not just #5. ------------------------- Dont forget to check the Fuel Injector also. You can test the injector by swapping the # 5 injector with the injector from any other cylinder. If the miss changes cylinder then the injector is bad.
IF and ONLY if you add a turbo or supercharger, you'll end up better aspiration (air intake) and at that point you may need larger injectors, but just changing the injector size will cause problems for the onboard computer as it tries to balance exhaust emissions.
Yes, It is a mechanical fuel injection system with an injector pump to pump fuel to the injectors.
Remove the upper half of the intake plenum. Dealer sells all needs seals as a kit and updated designed spider injector set.
You may have a bad injector/s leaking diesel past your pistons and mixing with your crank case oil...... pull the dipstick and "sniff" it.... you will smell the diesel.
IT just may need a tune-up, plugs and an air filter. But it could use an injector cleaning or replacement. You could try fuel injector cleaner. More serious problems could exist, however you could have the catalytic converter replaced. Have it checked out.Good Luck!
You can remove the injector, on your C 12 Caterpillar diesel engine, by removing the injector rail. Remove the retaining nut and the injector will come out.
Found what? If the injector is leaking, no O Ring will fix that. Replace the injector.
If it is just one injector, it is a bad injector or a problem in the wiring harness or connector for that injector. If it is all of the injectors, it could be a fuse, the entire injector harness, a broken loose or unplugged connector on the injector harness, or the fuel pump or fuel pressure regulator.
Depends on the engine, V6/8. In a v6 it is located in the intake manifold attached the the side of the Fuel Injector box. In a v8 it is located outside the manifold.
Try changing or checking the oil pressure switch next to distributor if it goes bad the engine will not fire or start. Motor (ECM) has to see at least 3 psi of oil pressure to start. And will also shut down if less than 3 psi.
The 1993 Ford F2 50 pickup truck injector solenoid is attached to the injector fuel pump. The injector solenoid should be labeled as such.
MIght be the injector itself.
P0200 Injector Circuit Malfunction Check the connections to each injector first. Then check voltage to each injector.
A saturated fuel injector is also known as a High Impedance (or High z) fuel injector. The high z injector has a larger ohm draw through the coil (12v-15v) vs. a peak-hold (Low Impedance, Low z) injector, which is 2v-4v. Another difference is the how the injector uses the voltage to open the injector. A high z injector uses the full voltage to open and hold open the injector, therefore it voltage saturated. A low z injector (peak-hold) has a peak of high voltage to open then injector then uses a lower voltage to keep the injector open for the remainder of it's cycle. What this means to you, the low z injectors typically needs a resistor in line to add the necessary resistance to properly drive the system, otherwise the injectors could overheat to fatigue. A high z injector does not need a resistor.
The same as regular fuels, Some parts normally need changing, (fuel rail materials, injector sizes, PCM/ECU programming,etc.)
Replace the bad injector.
