1 Answer

Fuel injector First I want to say thank you, so far all the info you have given he have been very helpful. I have one more question, my husband is somewhat a little knowledgable about cars and he is trying to get to the fuel injector and he says he kinda understands where you are saying the fuel injectors are located but to be sure he is doing the right thing he wants to know is there anyway maybe you can send me a diaphram for what he needs to be taking off and where it is located or can you give me a website to find it.

Im not entirely sure where to find a giagram on the internet. the best suggestion i can think to give you would be to buy a haynes manual from an auto parts store. the manual will give you step by step instructions on how to locate and remove them. and the manual only costs about $15 or so.
if this isnt an option, then ,let me know and i will do some digging to see what i can find

1987 GMC R 1500 4.3 won't start I have tried 2 switch wires...after installing the relay I noticed I had spark while hooking up the battery...I don't know what else to check...need help Thanks! Bobby

Engine cranking do you have spark at the spark plugs? Do you have fuel injector pulse? Any applicable trouble codes?
As far as the fuel pump, check ecm B fuse. Sometimes that fuse is located under the hood on firewall, close to fuel pump relay, not only check the fuse, use a test lite and check voltage on fuse circuit.
My wiring info for your model year isn't very good.

I have an 06 Chevy Cobalt SS on my Snap-On scanner it says fuel pump disabled it has something to do with the security system I guess is there any info you can give me on this thanks any pants

If my info is correct, part of your security system is starter motor disable, so, if it cranks good, I would think it is not your security system.
What about intermittent rpm signal, comes from crank sensor? If you lose rpm signal, you also lose spark and fuel injector pulse as well as fuel pump.
As far as the initial fuel prime, doesn't need an rpm signal.
Any applicable trouble codes?

My husband scan our 2006 Cadillac SRX and the code reads fuel pressure regulator. Can you tell me if where this parts located. I appreciate your answer. Thanks

What DTC ? P0000 what , What engine 3.6 or 4.6 L Need more info if you would like help .
The fuel pressure regulator attaches to the fuel return pipe on the fuel sender assembly. The fuel pressure regulator is a diaphragm-operated relief valve. A software bias compensates the injector on-time because the fuel pressure regulator is not referenced to manifold vacuum. The injector pulse width varies with the signal from the mass air flow (MAF)/intake air temperature (IAT) sensor.
With the engine running at idle, the system fuel pressure at the pressure test connection should be between 380-410 kPa (55-60 psi). With the system pressurized and the pump OFF the pressure should stabilize and hold. If the pressure regulator supplies a fuel pressure which is too low or too high, a driveability condition will result.

What are the advantages of using an injector car compared to carburettors? Is the injector better than carburettor?

Injectors are better!
Fuel injected engine is..........
  • More fuel efficient
  • Don't need to mix air & fuel manually.
  • Works in any altitude.
  • Faster distribution of air/fuel to the combustion.
  • Maintenance free( multiple fuel filters ).
Now a days all cars are electronically controlled fuel injectors, 50 years ago they use mechanical ijnectors.
Info on carb uses are other way around of the injectors.
More info will be in this site

Hope FixYa helped you out!

My 2000 intrepid will no start. My husband has recently replaced with a new alternator. The car ran fort the 2 days.After i shut it off it then never started back. My husband then replaced the fuel pump...

Check injectors for operation of solenoids. Put long screwdriver on injector and hold ear to screwdriver while someone cranks engine. If injector clicks once every 2 revolutions, injectors are working. If working, check fuel pressure at rail. If low, replace fuel pressure regulator (get back to me for instructions).

If injectors not clicking, the powertrain control module is not sending signals to the injectors. This could be caused by the camshaft position sensor or the PCM itself.

If you have more questions, please let us know.

I have a 93 volvo 850, it starts fine, but going down the road it chugs and tries to stall, I have to keep my foot on gas and brake to keep it from stalling at stops..My Husband replaced the fuel filter...

It definitely sound like a fuel starvation problem. Your hubby is on the right course by changing out the fuel filter. If the injectors are not getting enough fuel pressure from the fuel pump it could cause the condition you discribed. A new pump is fairly pricey but you could get one at a junk yard for far less.

1999 chevy blazer wont start


if your losing fuel pressure after the pump runs the drain back valve in the pump has failed.

and i doubt that you are seeing enough fuel pressure to run a vortec engine.

low fuel pressure equals a non running vortec
