check the ASD relay. it supplies power to the injectors. if you're getting power to them then the PCM supplies ground for the injector pulse. I believe it uses the camshaft position sensor signal to determine pulse, so test that sensor.

alright you're going to want to test the yellow wire at the cam sensor with the key on. it should have around 8 volts. then test the blue wire with the red stripe while cranking with the DC setting on the multimeter. it should alternate from 0-5 volts. you should probably check your crank sensor as well. the yellow wire will be the 8 volt power wire again and the blue with white stripe wire will be the alternating 5 volt reference. the third wire on both sensors will be ground. verify that it's getting ground as well.

Crank signal is also required for injector pulse. You also want to make sure your getting a good crank signal that is in phase (timing) with the Cam sensor.

If you or one of your friends have access to a Diagnostic scanner perhaps at school, it will give you details on both cam and crank signal.

he said the injectors are firing when the throttle plate is opened. do you think he might possibly have a MAP sensor issue?

no the 2.4 has a different MAP sensor with a different style connector.

I dont think map is the problem but testign it couldnt hurt. Look in the chiltons for a testing procedure. I dont recall if there is one or not. At Atmospheric or 0 PSI the Map wire to the ECU should show in the range of 4.4-4.6v.

So your saying with the throttle plates closed the injecotrs wont fire but when you crack the plates open the injectors begin firing? I cant even begin to explain that. I would Test the TPS. I wonder if you have a short where the TPS sits when the plates are closed.

agreed... that doesn't make much sense to me either. MAP and TPS are the only things i can think of that might possibly cause that. even then it still seems strange that it would only fire the injectors with the throttle plate open. it could just be a coincidence though and still be a pulse signal problem.

Are you basing that off anything or just throwing that out there?

if he has spark I dunno that it's a sync issue... what's your fuel pressure? How exactly do you know there's no fuel coming from the injectors?

but if you push the throttle a bit it spits fuel?

Then I say like the the others, check your TPS voltage at closed position. It may be bad (~5V reading on signal), making the ECM go into flood-clear mode. It normally only does that when the throttle is like 75% or something.

yeah I'd say test the TPS sensor. the 5v signal wire should be the green wire with a yellow stripe. also measure the resistance at the TPS side connector between terminals 1 and 3. should be between 3.5-6.5 kohms. then measure resistance on terminals 2 and 3 again on the sensor side while slowly opening the throttle position. make sure the value changes smoothly in proportion with the opening angle.

wide number of things. fuel pressure is where you should probably start. fuel pressure should be 45-50 psi if memory serves me correctly. need to verify good fuel pressure before you go any further. we could guess a lot about what could cause that.

there is, i believe, but you shouldn't have to adjust it if it's the stock throttle body. you may have a vacuum leak. verify that all vacuum hoses are connected and you have no open ports in the back of the manifold. your intake gaskets may be leaking.
