Started the car last week, it idled for a few seconds... and then it just died. Tried to start it, but nothing...

I discovered today that it flods the engine, alot... I have gas coming out my exhaust when i crank it. And when i pull my plugs to air the engine, it squirts fuel all over the place...

So my injectors must be running at max... Why?

I ´ve tried 3 different ecu´s...

Can it be the map sensor?

What more has something to do with the injectors?

Xeros

your injectors might be stuck open?

Master-Yoda

Forgot to say, i´ve also tried different injectors...

you may have a problem with the ECT , MAP, TPS or the wiring between these sensors. You may also have a problem with your spark circuit (coil,plug wires, etc.). A scan tool is your best bet to determine quickly where your problem lies. If you don't have access to a scan tool, check for power and ground on each circuit with the key in "on" position. If you find one that does not have power or ground, check for resistance with the key "off". If you have power and ground the component is the likely culprit. I would recommend getting the wiring diagram for your car so you know which wires you are testing and what voltage you will be looking for. Don't use a cheap DVOM or test light as you will likely fry the PCM.

ECT?

I know TPS is fine also, checked it with the Apexi pfc...

Couldnt you get a set of noid lights at harbor freight, and check for pulse or constant signal. Also make sure the injector setting has not changed on your pfc. You have probly checked that. Good luck.

I also though about the noid lights... Probably try that...

But since i´ve tried 3 different ems, it cant be the injector settings...

This might be a stupid question but do you have spark? Your ignition coils might be pooched or your wires; or the plugs are so fouled that they don't work anymore.

Yes i have excellent spark...

And i tried several different plugs...

But it has to do something with the injectors. Yesterday when i tried to start the car, maybe tried to crank it a few times... Then i discovered i had gas almost under the entire car!!! Because it came out the flang around the midpipe... So i´m glad it didnt start that time...

The injectors has to be at max... Gonna trie a noid light today... Anyone has any tips on how that should look? Slow flashing, fast?

idk just a wild guess, check the diffusers on the primary injector bungs. Sometimes those can break or aren't installed and can cause some major flooding

Short of injectors being wide open i cant imagine that much fuel from 2 injectors. Check the secondaries to maybe there is a signal crossed to them, there alot bigger. Diffusers dont have any thing to do with flow.

How about leaking lower injector body o-rings?

Master-Yoda

I´ve tried disconnecting the secondarie injectors...

Master-Yoda

There new...

Speed of light

You might want to check your engine harness for injector wire shorts (esp to ground), I don't remember for sure, but I think this could cause continuous operation of an injector under certain circumstances.

Master-Yoda

This is strange...

i borrowed injectors from a friend, replaced mine in the fuelrail. And when i try to crank the car, theres no fuel at all from injectors??? (I´m running fuel rail on the side, just to check the injectors).

I´ve checked the signal to the injectors with a noid light, and there is a signal.

Can these injectors be broken also?

Busted7

If they have been setting they can stop up and not flow. Try friends injectors with 12 volt signial and listen for clicking. Dont hold power on continous just tap and listen if they click they may be stopped up.
