1994 Saturn SL1 no Pulse to injector

The speed sensor has nothing to do with injector pulse's. How did you check for injector pulse's?Did you use a noid light or some other way?Let me know so we can figure this out.

The ecm control's the ground to the injector that's how it pulse's the injector. So do you have spark?If the injector ground side isn't pulse's it's going to be the wire's or the ecm. So what happens when you try to flash the code's out?You said it won't even give a code 12 which it should they all have that code. So what's the whole story?Did you just have a crank no start one day?Or did something happen to cause it to not start?

If you have no injector pulse I would check fuel pressure also. But if all your missing is injector pulse then your left with the wiring and the computer if you try a computer I would find a good used one.

Yes the light blue wire goes straight to the ecm and that is a pulsing ground while cranking.I would take a ohm's meter and go from the terminal to the injector to the terminal of the ecm it should be 2 ohm's or less.I also emailed you the diagram.

If you look a little closer it show's both the four injector and single injector that's why it show's 5 injector's one of those injector's is labeled TBI which is throttle body injection which yours is. If you donate under the user name you used to ask the question with I will get the money i'm suppose to get when you donate no worries there.

Nothing in life is for sure lol. But if you rule out the wire and terminal tightness then all your left with is the computer. If your getting 2 ohm's from terminal to terminal then there is no point in removing the wire from the connector. Now your left with terminal tightness and the computer.

First of all thank you so much for your donation. Your welcome glad to hear you got it figured out.I hope you got a used computer the new one's can be expensive.
