2003 Chevy Tahoe LT 5.3 liter Vortec NON Start
Hello everyone
I have a 2003 Tahoe 5.3 Vortec engine that will not start.
Let me give everyone a little history that let up to this point. The Trucks problems started the 3rd gear solenoid acting up and not shifting gears correctly, the truck had the steering box replaced a few a months after that. After the steering box was replaced I got a Airbag sensor Check message. Took it to the dealer to check it they had the track a half a day and was only able to coming up with was it was "Maybe" the Steer-wheel sensor. I took back my truck and continued to drive it that way up to a few weeks ago when the Gauge Clusher, Driver side control panel went out (but the rear control panels work, Alarm, Wireless Entry(Key Flob), Power Locks, Radio, A/C, Seat Heaters. But the Power Seats work (No Presets driver settings), Power Paddles, Speedo & Tach worked fine for awhile.
Now I can not start the truck at all after driven it for almost 1 month after the other things went out. I drove the truck all morning the day of it not starting until late that evening when I went to start it and nothing. The starter will try to start but shut off after a few seconds of trying to start the truck. I check the Battery connecting and they were fine. It has Gas and the Battery is only 1 month Old. I have since replaced the PCM and that fixed the other problems and the truck turn over but no start.
