I have an 89 Chevy S10 2.5L 5 speed (manual). It did NOT have an ECM in it when I bought it. I put one in it from another s10 but I can’t get fuel to come through the injector. Could this be caused by the ECM not coming from the correct matching truck? Mechanic's Assistant: Have you noticed an increase in fuel consumption? And how does the S10 start—same as usual? It won’t start it cranks but won’t run Mechanic's Assistant: What year is your S10? 1989 Mechanic's Assistant: Are you fixing your S10 yourself? What have you tried so far? Replaced fuel pump, fuel filter, fuel injector, [spark plugs](/topics-spark-plug-chevy/) and wires, control module in the distributor Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? Replaced the pick-up coil also

Did the pcm you installed come out of a truck with a 2.5?
Automotive Expert
It is possible that the eprom is incorrect, but the truck should still start. Do you have a digital volt meter and a test light that does not have an led bulb in it so we can do some testing?

No I don't have a volt meter and test lightThe fuel will make it all the way to the throttle body but won't come out the injector

I will walk you through the testing step by step if you can get these tools to work with.

Where you able to get a test light? The used computer will not be the problem. With a test light and digital volt meter I can help you find the problem.

If the jerking reaction is something related to pressing the brake pedal, this may suggest a faulty brake caliper. If your vehicle pulls to one side when you apply the brakes it typically means that you have a braking imbalance...
