Re: 92 rs injectors not firing

Do you have spark?

No injector spray, no spark may mean defective distributor parts or defective wire harness between distributor and ECM, or a defective ECM. I'd be looking at distributor parts, first.

Spark but no injector spray may mean defective wire harness between injectors and ECM; popped fuse, or no fuel pressure.

Re: 92 rs injectors not firing

Re: 92 rs injectors not firing

If you did that then you know its got spark and is fuel related. I usually test that with starter fluid spray.

Check the injector fuse?

Check the car for codes and see if its throwing the dreaded code 54 fuel pump.

Check the fuel pump relay.

Lastly is there fuel in the tank? The gauges on these cars can get really off. Mine shows 1/4 tank when empty these days.
