2008 Trailblazer Dies And Wont Start

Unread post by Slim » Wed Dec 26, 2012 3:13 pm

I have a 2008 trailblazer with about 88000 miles. It died on me while driving. Almost like it was out of gas. I tried to crank it and it started but quit again after a few seconds. Now when I turn the key I get the dash lights but it won't turn over or even make a sound. It wont shift out of park when the key is in the run position and the steering wheel won't lock when the key is removed.

A code P0601 is for the read only memory (ROM) of the vehicle's computer. This is telling you that there is a problem with the internal workings. There is basically no fix for this other than to replace the computer (PCM). After replacement, it would need to be programmed, so your best bet is to take it a GM dealership so it can be done properly.

ok, 04 t&c no start, no crank. Click only.

Shouldn't be too bad. I always say that and then get buried in weird stuff...

power from the ignition switch to pin# 86 on the starter relay. Grounds through the starter relay control in the integrated power control module pin# 85 on the relay.

relay clicks and them power from fuse# 9 (40A) to pin # 30 on the starter relay connects to pin# 87 and goes out to the starter solenoid on a yellow and gray wire.

Verify that the wire to the starter solenoid is powering up with battery voltage when the key is in the start position. If you have battery voltage and you can hear and maybe feel the solenoid clicking then go to the second part of the starting system.

The big battery cable that goes from the battery to the starter. Make sure you have good clean connections at both ends of that cable. The power to spin the starter comes from this cable.

if those two circuits are both good then you should be drawing a lot of current through the battery cable to the starter. If you turn the headlights on and crank the engine (put the key to the start position) it should dim the headlights. If it doesn't then you are not drawing a lot of power from the battery. If the headlights do dim a lot then you are drawing a lot of current. If the engine is not rotating then see if you can rotate the engine by hand.

Key off and trans in park. Key out of the ignition. (to make sure you don't have it so the engine can start if you get the engine to rotate. Use a socket and a breaker bar or long ratchet and see if you can rotate the engine by hand. If the engine won't turn then you have to remove the spark plugs and try to rotate it by hand again. Looking for a frozen engine of an engine in a hydrostatic lock condition. Rare bet it can happen.

but more likely an electrical problem with too much resistance in a circuit somewhere. you just have to find out what circuit and where...

03 trailblazer 4.2l rpms fluctuate between 1500 and 2000

Unread post by mstr1073 » Mon Nov 26, 2018 1:12 pm

While driving at hwy speed ( 50-65 mph) with a constant throttle the rpms begin to jump from 1500 - 2000 if i am above 2000 rpm it runs fine. i had a code for crank shaft position sensor that the guy erased and it did not come back but problem remained I have since replaced the sensor and still have the issue. does anyone have an explanation or fix?

you should drive your truck with a scanner on it while it is acting up. Look at the trans section. It could be the transmission is locking and unlocking the torque converter or it could be shifting in and out of overdrive.
