I owne a 1993 saturn. it has been parked for 5 years. I got an ex co worker to look at it . H first said he could get it going in a few days. it has now been over 4 weeks. & it is still not running. First he put on a new fuel pump. that did not work. Then he cleanes the gas tank & checked the fuellines . then he said the fuel injections woere not kicking in. I sugested maybe a carbaritor kit.. He came back & sait it needed a new computer. The car was working fine when I parked it . Can you tell me if all this sound' right & maybe what it could be. Thank you gene

new fuel pump-- clean out the fuel tank & lines
Hello and thank you for your post. I am a master certified GM tech, with 15 years Saturn experience,and can help you to resolve your issue.
have you checked for spark and fuel pressure and fuel injector pulse?
We need to see which you have and which you do not have so I can give you some idea as to what is causing this

the friend working on my car said ( he was checking the the fuel injectors & they were not firing. I ask if he checked the carbriator? he said the fuel injectors were in the carbarator & they were not firing.I did not know to ask about the spark & fuel pressure.but he said he tryed to by pass the fuel pump streight to the ignition & that it would not work . I didn't ask why. but he sait that it would need a new computer. He is trying that now(tonight) could that be the right thing to do?
I cant say. The fuel injector is fired via the computer but usually when it will not fire, it is due to either a blown fuse or crank sensor.
Let me know how he makes out with the car.
If it still will not run, I need to know if the injector is electrically firing. I realize there is no fuel coming out of it but is it being turned on and off. He needs to use an LED test light or a noid light to determine this.
Then tell me if there is fuel pressure or spark.
We'll go from there
I called my friend . he said the injector is not electrically firing & it is not turning on & off .but he is getting both fuel pressure and spark. & has not replaced the computer yet . he has checked the fuse & there are no blown fuse.He has not checked the crank sensor yet but will do that tomorrow after work. thank you so much & I will get back to you then. even I am learning about my car. I will except , but not yet just incase we need more .info ok?
the crank sensor is good if there is spark.
The injector uses the same signal as the coils to fire.
if the car has spark, it should run on starter fluid sprayed into the throttle body.
have him try that to be sure that is whet is missing. (injector pulse)
key in run, the injector should have 12V on one wire and when cranking the ground should flash on and off
if not and the inj fuse is OK, the fuse needs to be checked for 12V present or not.
Maybe the fuse isn't getting power?
If it is and it isn't getting to the injector, then it is an open circuit between the injector and the fuse box under hood
