1G 90 eagle Talon problems

[Robtsi]

1990 eagle Talon awd turbocharged with 5spd transmission. Won't get fuel through injectors AT ALL. has spark and compression. Thinking electrical issue. Any help or troubleshooting tips greatly appreactiated

Check the fuel pump relay and pump http://www.dsmtuners.com/threads/how-to-diagnose-a-no-start.217951/

Are injectors even getting signal to fire? No need to test fuel pump if this isnt happening.

I have fuel getting to my fuel rail and it is under pressure so I would assume my Fuel pump is OK.
I did take off the connectors that plug into the injectors and did a ohm test. it read about 2 ohms. still stuck though considering the injectors appear to be perfectly clean. I am confused to say the least !

Check all fuses first then do a voltage test at injector connectors and then just back track the wires.

?...original 450 bluetops...?

Had to replace all of mine due to age.

did you clean the old injectors yet?
try using a AA battery to try and energize the injectors do they click when voltage is applied?
if not remove them, clean the injectors and try again, if you do manage to get them to click and the car will still not start with them bolted on then the ecu is not firing the injectors, or it could also be the resistor pack you should check it as well :see image below for the testing procedure.

I will try today. I will run through all of my electrical aswell and test it all with my multimeter.

Hmm idk about those injectors there 5ohms stock but when mine went they were 76 ohms and were stuck closed but id highly doubt all your injectors went.at once so check the resister pack and look for a.bad ecu and you could try and use conitnuity to check weather the injectors are stuck closed or not but.I do no turbo injectors are 5ohms stock ,did anything.happen before.you had.issues like anything

And btw a (aa )battery wont.do anything.injectors are 12volts not a whimpy 1.5 like a AA battery

Actually using 12 volt car battery is not safe on a fuel injector you could blow it out [unless you have a series resistor], it's too high a current as opposed to 1 AA battery, all they need is 1 AA battery to open and close, I know this works because I personally have made my own injector cleaner, and I did a bit of researching on the subject, I have cleaned my own supply of 450cc injectors on my 1g dsm using only 1 AA you could use 2 AA batteries if you had higher cc injectors, I would not recommend going much higher on stock 450cc injectors, but in reality current is what powers injectors not volts so keep that in mind.

^ true, doesn't take much current to knock out a injector.

The crank sensor fires the injectors and ignition on a 90. Do you have spark?

Having similar problem. Was driving on highway today cruising around 45 mph in snow storm 4th gear. Suddenly car loses power and I pulled off the road. Fuel pressure reading 32 at idle vacuum hose on. This is where I have been running it. New O2 sensor and also a wb sensor on downpipe after bend. Plugs new 500 miles on them. Wires new. I know I have some small vacuum leak at boost gauge filter. I taped it up and that stopped leak. I'm only driving in cruise conditions, staying out of boost. Car starts up no problem, but stumbles when I try to gas it.
