no signal at fuel injectors.

I have a 91 olds cutlass supreme with a 3.1L, and there is no signal to the fuel injectors. The fuse is good, and I suspect the fusible link is bad, but I don't know where to look for it. Does anyone know where it is located?

From what I understand there is no fusible link in the injector harness.

 

You need to check your crank sensor. If the crank sensor is bad (been there just recently) then your injectors will not get any pulse from the ECM. Pull the plug and test the resistance accross the pins. You should get about 50k Ohms. Anything more and it is fried. If the crank sensor is good, then start looking into you ignition module. First by checking to see if you have spark, as mentioned above.

 

Again the only fusible links as far as I know are in the starter wiring.

 

To recap:

 

1. Check for spark

2. Check crank sensor

3. Replace sensor if faulty, more than 50k Ohms.

 

Cheers and good luck.
