May have a faulty air/fuel ratio sensor or o2 sensor, throttle body may need adjusting or have a stretched spring or there may be grime restricting air flow so it's flooding it.

Injectors not firing on GM 3.8 engine on buick lesabre 2004


Are you missing anything else? Engine cranking, do you have spark at the plugs? Also, use a gage and check proper fuel pressure, engine cranking. Any applicable trouble codes? If your missing spark--fuel pressure and fuel injector pulse, I'd have to check for rpm signal, usually, comes from crank sensor.
Key on, did you check for voltage on pink wire at fuel injector, use a test light to check for voltage. The computer grounds the fuel injector if rpm signal is present.
I don't know what testing you have done?

No can't be PATS . PATS on your vehicle disables the starter . Pull a spark plug wire an check for spark , do fuel pressure testing etc...

My 1993 Dodge Dakota 3.9l v6 4x4 magnum wont fire it will crank over but no fire? The fuel pump relay, crank shaft sensor , spark plugs and wires were replaced. I don’t know a lot about this no fireing...


check the compresion in all cylinders 100 psi (compression good) check the spark -check the fuel pressure.30 psi at gauge with switch on.(if no keep pressure with switch off injectors or fuel pressure regulator are bad
check the signal to the injectors (get little injectors tester at autoparts) if no signal check the ground to the injectors black wire
or the other wire (computer)= good signal to injectors and good fuel pressure and good spark (defective injectors)

Cranks over. But wont start.


Pull the injectors and have them tested for electronic continuity and spray pattern as the needle may be rusted up or the coils in the injectors corroded away for the long period of no use. Regardless of what engine you have if you have spark at the correct time --compression --fuel then you must have go in the engine . Continuing to run will depend on the make and design as the other variables come into play.

IF NO FUEL PRESSURE AND FUEL PUMP RUNS REPLACE PUMP .. CK VOLTAGE TO FUEL PUMP WHILE CRANKING . CK USING PUMP GROUND WIRE AT THE PUMP CONNECTOR THIS WILL PROVE GROUND ALSO. USE TEST LIGHT TO VERIFY

My 1986 Toyota 4x4 won't fire up


you will need to drain the fuel in the tank and replace the fuel filter and plugs after a couple years the fuel will go bad and it will plug the filter and foul the plugs if you do those 3 things and in that order it should start it is important even though you have good fuel pressure that you replace the filter to prevent damage too your injectors

Continues cranking. Wont turn over. what s my next step?


You mean it cranks but wont start (cranking and turning over are the same thing) When cranking, rap on the fuel tank, if it then runs, the pump is bad and will need to be replaced.

I have fire and fule I just replaced the spark plugs and redid the timeing and it still wont start what ellse can I do?


are the injectors opening? fuel pressure doesn't mean the injectors are delivering any fuel to the cylinders, does the system have any trouble codes? if u are not sure if the injectors are getting a signal buy a NOID tester from NAPA or a tool dealer like Snap-On, it is very easy to use, plug it onto the fuel injector connector and crank the engine, if the injectors are getting a signal the light will flash, it is kinda hard to see so do it in the evening, if the injectors are not working then check to see if the computer has power, if the computer checks ok then u may have an issue with the engine wiring harness, very common on this car. also make sure the timing belt is ok.
