The left side injector is not receiving pulses. I swapped injector wiring between the two and the left side injector functions. The left injector wiring is not shorted to ground or each other. I replaced the ECM and the problem persists.
SOURCE: 89 s10 2.5 has fuel and fire injector has power but no pulse
injector pulse is just controlled by the ecm or computer as some would say,u said u replaced wires? did u have a fire or melt wires? ecm is known to go bad on these,had a few of these trucks back in the day.

Check the fuel pressure at the shredder valve, you should have 13 to 13.5psi, anything other then that will give you problems in the GM TBI. If the pressure is bad, then you may have to replace the fuel pressure regulator at the bottom of the TB.
Good luck and keep me posted.

Perhaps the security key is not working with your car, but I am surprised that it would start at all with that working against your trying to start and run the car.

I have expereienced this issue several times on the 2.2 ecotech usually ends up being the ignition module itself. I keep an extra module handy just for testing purposes.
Condition/Concern:
Some customers may comment on a severe engine misfire and a SES Light. Upon inspection, DTCs P0300 - P0304 may be found due to misfires on cylinders 1 and 4 or cylinders 2 and 3.
Recommendation/Instructions:
If this concern is encountered, inspect circuits 406 (IC Control for 2/3 Coil) and 423 (IC Control for 1/4 Coil) for an intermittent short to ground or poor connection on either end. Depending on the model, these circuits may short on the AC lines near the AC compressor, on the transmission mount, or on the transmission lines where they enter the transmission. If there is no problem found with these circuits, inspect the ignition control module ground to ensure that it is clean and tight.
If there is no problem found after performing the suggestions above and the SI diagnostics lead to ignition module replacement, replace the ignition module as directed but also replace all of the spark plugs and clean the ignition module ground to possibly prevent future ignition module damage.
Measure the resistance of the ground circuit of the ICM from the harness connector of the ICM to a good ground. This should be 3 ohms.If it is not replace the module.

There are a few possible causes of the blocked fuel injector in your car: mechanical failure; electrical problems; damage caused by overheating; and the most common reason, blockage caused by grime. The best way to avoid injector problems is to take your car in for regular maintenance and use the occasional fuel additive specifically designed to keep fuel systems clean
