Haha. . .injectors don't open for starters (it's like a fan constantly blowing mist through) your lines could be clogged, but highly unlikely cuz that wouldn't prevent it from starting...what makes you think fuel pump is fine(because you hear an electric purr signaling actuator is on and working properly? did you test the line, pressure, compression and then actually di a timing/amount thinking not? you need to power the pump...then see what your actual amount is vs spec...then being eletrical...trouble shoot ignition and throttle body...that should cover all your basics...then you'll have a better diagnostic and can make a more conclusive fix?! (I cant stress enough how important it is to check the actual output of your fuel pump! )good luck...!!!

-Use noid light, disconnect connector from injector (1 at a time)
-Ask some one to help you crank and
Check power at the wire connector . If there is power there then possibly fuel pressure is low.
-If no power at all then most possibly cause is the Crank and cam sensor. It doesn't produce any signal. (It's bad)

Good Luck

SOURCE: Golf 2 gti k-jetronic problem

First check the filters... There is a high pressure filter near the fuel distributor and a strainer in the tank... Connect a fuel pressure gauge at the fuel distributor... there are 2 test ports for this. One is "system" pressure the other is "control" pressure... you want the "system" port...if no (or very low) pressure then I would suspect the fuel distributor itself... If pressure is good and still no spray from the injectors then either the fuel is very dirty and has clogged the injectors (not very likely except in extreme cases of neglect) or the injectors aren't getting a signal (or an intermittent signal, more likely) from the injection control unit. If none of this helps you will need to get the Bentley manual and follow the troubleshooting steps...;-)

SOURCE: 1995 jetta 2.0 fuel pump

ok could be a few things.

Have you changed the inline fuel filter? these usually have paper filter elements and after a while can be clogged with moisture which blocks fuel flow. The fuel pump will still have good pressure but the fuel rail will lack the flow required and you may burn out an injector as its running too lean. Secondly, the MAF sensor, could be dirty, clean it with electrical cleaner.

I think its more likeylt the fuel filter blocked. Try and bypass it if possible, reset the ECU and try agiain

Fuel pump pumps when cranking but does not prime, also the injectors are not opening.

There should be a valve on your injector fuel rail. looks lie a valve stem in a tire. , depress the valve and see if fuel sprays out. you may want to get a fuel pressure gauge to check and see what kind of pressure you getting if any at all. ,

Flooding 95 mustang with a 3.8

Well if it is flooding, either something is shorting out the injectors and causing them to be wide open, or one injector is stuck open, or you have a pressure regulator leaking liquid fuel into the intake.
Are all of the spark plugs wet ?
Can you start the engine if you disable the injectors ?

1990 montero no start. No power to open injectors, good fuel pump

Check the injector pulses with an osciliscope. If you arent getting a pulse check the ecu. I have cooked 2 of them. One killed my ignition but had good fuel. the second time it wouldnt open the injectors but had good spark. A quick check is to take the ecu out and take the cover off. then look for burnt electrical components.
