Hello. New here, but I've been on some other forums for years. I just bought a 2008 3/4 ton 4X4 Suburban from Canadian gov't surplus. Was formerly an RCMP unit. Got a good deal on it, as it's non-runner.
Put the key in the ignition (got 2 keys and fobs), turn it one notch, gauges and dash warning lights illuminate. All lamps, as far as I know. Wait 10 seconds or so, and all lamps except the "engine icon" go out. So far, that's normal, right? All lamps come on for bulb-check function, then all go out. Engine lamp remains on because engine has not started.
Turn key another notch to crank position, and zero. No crank, no click, no lights. Nothing.
What I know so far: vehicle had a remote start (after market) on it, removed before I got it. Also had all the usual cop gear, mostly removed. (they left part of the alternate headlight flasher, which I removed).
Batteries (2) are fully charged. Starter will crank engine fine if jumped at the solenoid, or if I take the cover off the starter relay and close it manually. I squirted some gasoline into the intake manifold via a vacuum port, and with the ignition switch on, closed the starter relay by hand and the engine started, and ran very briefly. So the ignition system works, at least while cranking. I can't be certain it works when starter is disengaged.
Fuel pump does not run with ignition turned on, but will run if fuel pump relay is jumpered, and pressurizes fuel rail OK. Cranking engine with fuel pump relay jumpered will not start it. Conclusion: injectors are not firing.
Been doing lots of reading; thought it might be the anti-theft device. Security light comes on during bulb check, then goes out. Supposedly, if anti-theft system has triggered, the security light should flash. Tried the ten and thirty minute "security re-learn procedures", no joy.
I'm away at work for 2 weeks, and the dead 'burb is at home, but I will archive any responses, and try them when I go home.
I like my 'burbs; also have '96 with 6.5 Diesel, '97 with 350 Vortec, and an '88 with 6.2 Diesel. All 3/4 ton 4X4.
