HelloCustomer
You need a scan tool to look at the data.Make sure the ECM is still showing a cranking rpm when the injector quits.Make sure the TPS is not going wide open into clear flood mode.The data going into the ECM must be good for it to function.Test to see if you have 5 volts & a ground at the manifold absolute sensor & the throttle position sensor.
