Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
key ON engine OFF the fuel pressure is 55 to 60 ?
can you unplug any fuel injector you can get too and with the key ON does one of the terminals in the injector connector show 12 volts ?
if so then connect a test light clip to a good 12 volts at the battery then when cranking it over touching the test light tip to the OTHER terminal when cranking it over does your test light bulb blink ?
if this will run on fuel being added and it has the fuel pressure i said the issue is the computer not telling the injectors to fire by the passlock theft key system or a bad computer or missing power to the injectors or the rare outside chance the fuel is contaminated with water
if it has spark then that is what your up against
can you try this and see if it will run ?
IMPORTANT: The vehicle learns the Passlock(TM) Sensor Data Code and/or password ***** the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.
ok then we are back to we need to see if we have power at one terminal and a blinking ground at the other terminal the odds are there is no blinking ground and this would usually mean a bad computer or the passlock sensor is not working correctly and even the relearn will not work because the sensor can not read the key to be able to perform the relearn
tests need to be done to be sure on what exaclty the problem is
we need to test like i said needs to be tested and a scan tool to view live computer data and see if the computer is in theft lock stopping the injector pulse due to the pass lock system
