SOURCE: no injector pulse
absence of ground pulse means there is some kind of shorting circuit in your control circuit.
which can make the ground pulse to get shorted there itself preventing it to reach the circuit properly.

sounds very much like the coolant temp sensor
, this tells the pcm that the engine is cold, sometimes they fail and tell the pcm the car is at -40 degrees, the pcm then tries to compensate by keeping the injectors open for too long flooding the engine. the part is inexpensive, and normally easy to replace. It can be checked with a scan tool, or a volt/ohms tester,

Injector pulse comes from Cam sensor, If you have a BAd CAMSHAFT sensor you will not get injector pulse, replace sensor and that should solve your problem. Good Luck and thanks for using FIX YA
