My 1995 GST does not turn on please help

[david mendoza]

GOOD DAY FRIENDS
I have a problem because in the plugs of the injectors I have positeva current in both
change tablet coils
resistorpack
I do not have any bad cable since it can be
my dsm is an eclipse gst 1995

Check your ecu.

 

[chrysler kid]

Have you had the amperage of the battery tested

 

[david mendoza]

Check your ecu.

already change the ecu of barios friends

 

[david mendoza]

Have you had the amperage of the battery tested

yes is good

 

[Spideydsm99]

Have you tested the Mfi relay?

People on this forum are crazy with this ecu stuff. Its simple, fuel, spark, and compression. Use a spark tester to verify the coils are firing, use an alternate fuel source like brake clean, propane, or something to spray into the throttle while cranking to see if its fuel, and check compression to see if its good. If not check timing. Then you will be looking at crank sensor and other inputs etc. to see if its a command that's inhibiting the system. Its not even logical to jump to the ecu first. That's a final test if all other systems check out.

@Turbo 2g did you not read his post?
Btw your forgetting air. Lmao

 

[Spideydsm99]

Because from what I’m understanding is his injectors plugs has continued positive current on both wires.

Forgetting air? What? A bag around the air filter? There would be no compression if there was no air. Compression includes air for future reference. The things I mentioned are what you start with if you have a no start syndrome. Im only the lead tech for my shop But ya.. start with ecu problems

I for one can't even fully understand the original post. Put a noid light in and see if the injector control is flashing. I don't know if he really knows how to check the system. I'm just saying what I would start with. In my experience, people trip themselves out on things that arent even there because they skip the basics.

 

[Spideydsm99]

It’s a joke dude, Calm down a bit. But if he’s getting a constant signal to the injectors of course it isn’t gonna run. So he’s checked the injector resistor module, well what’s next in that line up??? Mfi relay, can angle sensor and the ecu.

 

[Spideydsm99]

If you can’t understand the post then why even post?

David, what are you testing for power with? If you are using a test light, you will not see pulse because it happens too fast. It will appear as if the light stays on. You would need a noid light, a lab scope, or a fast enough DVOM to catch the pulse.

What I am confused about Spidey, is what the real issue is. I believe there is power at most times on both terminals because they are physically connected by the connector. One side is grounded for a millisecond by the ECU when cranking/running. So how is it that he is seeing this millisecond grounding not happening? I don't think its being tested right personally. But if the OP can show how he's really seeing constant power at the injectors, then I'll believe there is some sort of issue with the computer side of things.

Furthermore, he already stated be changed the ecu and the resistor pack, and I doubt all 4 injectors failed. Even if the injectors aren't firing, I'd be wiling to bet its due do something else entirely. Like CAS for example. I just don't relive that is the real issue yet. People test this sort of thing wrong all the time and get tunnel vision on what they think is wrong.

 

[Spideydsm99]

I just suggest the cas.....

 

[david mendoza]

good friends change wiring because one of the plugs was holding short
and the mpi did not work well thank you very much everyone

Glad you got it started! Be careful with what you spray into the throttle body as a fuel source if you ever need to consider it. Can cause a load of problems if used improperly.
