2007 chevy colorado will not start

My 07 Colorado started giving me problems. I parked it and 10 mts later it would not start. The engine cranks with full strength but it wont start. 20 mts later I came back and it started like nothing. This was happening only once a week but it started doing it more often it usually only did it when the engine was hot. Today the engine was cool and it did not start.

    I park and it's any ones guess if it'll start when I try it again. But after about 30 mins it starts like nothings wrong. then I may not see the problem for days before it happens again.

    I have the same issue with a 2004 Colorado. It sounds like it will start (turns over fine), but nothing happens. This only happens occassionally and always when hot. Let it sit for 15 minutes and it starts right up.

    its not the fuel pump, or the battery, or the fuel pump relay i believe it is electrical demons the starter, or the ignition by the way the starter is near impossible to get too

    I have a 2006 with an I5 that has been doing it off and on for the last year and a half. I received 2 sets of keys with fobs for it when I bought it. I have used one set for the last 7.5 years, I recently switched to the other key (Dec 2013) so far no problems, starts every time and I notice the newer key goes on tighter and is not a loose. Try your other key and see of this cures the issue.

    Had the same issue with my 2006. I received 2 sets of keys and fobs when I bought it new and have been using the same 1 set for 8 years, recently (December 2013) I switched to the other key, starts up every time, even noticed the key fits tighter. Try the other key set and see if this cures it.

I have the same problem on my 2007 colorado pickup, 4 cylinder, 2.9 liter engine, with about 52,000 miles on it. It happend once when I let my truck sit for a week and recently when the engine was cold. In both cases I removed the air cleaner and shot some ether/start fluid into the air inlet. The engine started instantly in both cases. I also thought that maybe I had a vapor lock problem, with my locking gas cap, so I removed the cap and fiddled with it to see if something was sticking. I also thought maybe in the winter, my low test fuel was not vaporizing correctly in the engine, so I switched to super/premium hytest fuel I did this recently when the engine would not start, just for a possible cause/cure. I also put some fuel injector cleaner in the tank, because I thought maybe
something was causing incorrect fuel atomization with the injectors. Next I want to put some lubricant in the fuel tank (like Z MAX or Marvelous Mystery Oil) to see if maybe something is sticking in the fuel pump. In any case when my truck cranks and won't start, I remove the air cleaner and shoot in some starter fluid in the engine and I know my engine will start. It works every time.


P.S. I run the Bosch 4 prong Platinum spark plugs. They have about 50,000 miles on them and I want to put in a new set. I also run the 50.00 dollar K&N lifetime air filter. I'm actually on my second one because I didn't want to clean the first one. I run pure synthecitc oil at 8.00 dollars per quart and drive about 15,000 mile before the oil turns from clear color to black. I run a very expensive oil filter which cost about 14.00 dollars. I want to put in a new battery for the heck of it and I want to put in new HP coils just to see if the cars runs better with High Performance Coils. I might even try some expensive spark plug wires, just to make it easier for my engine to start or maybe give a little bigger spark to the plugs. I just feel fuel injection is not the best system when you start the engine. I feel the gas has to be very volatile to start the engine. Ether or starting fluid ignite very easily.

Could possibly be a fuel pump issue as well.

2007 chevy colorado has problem starting


If the security light is on, the problem is with the Vehicle AntiTheft system. The key with the chip is not being read in the ignition cylinder. Therefore the computer doesn't allow it to be restarted for 10 minutes.

What is the Security Passload Sensor on a 2007 Chevrolet Colorado?


I have an 07 colorado and had this very same problem. Ocassionally i would hop in the truck and stick my key in...it would turn over but not crank. I read numerous threads that is was my crankshaft position sensor....like you i would wait ten minute and it would crank right up. After i replaced the sensor, 2 weeks later it did it again. Read more threads...got a brand new key and took off all of my keys to reduce weight on the ignition cylinder. 2 weeks later it did it again. Finally I figured out that all of those threads were wrong. My passlock light was flashing during those 10 minutes of waiting for one reason!!! My positive battery cable had corrosion on it. Even a little corrosion on your terminal will trick the passlock sensor into thinking the truck is being hacked and will not crank. Take it from me, clean the **** out of your terminal wire the proper wire brush and neutralizer, then coat the terminal and cable connection with a pile of either bearing grease or diode (red) grease to help prevent future corrosion. 4 months later i still havent had the problem come back, and I had it happen over 6 times in two months. Try it and see.

2007 Chevrolet Colorado will not start, wait 10 minutes and will start.


Someone will need to figure out if you are lacking spark to the plugs or fuel to the injectors when it won't start.

2006 chevy colorado has power wont crank


Do you have a security light flashing in the dash when you try to start it, does the starter spin the engine for but not start it up? Have you tried spraying fuel into the intake during cranking? Do you have spark? Any fault codes? All this can be the problem and other things as well, have them all eliminated as the cause.

Out of the blue my chevy colorado won't start if i disconnect the battery then hook it reconnect after a couple minutes it will start


does the unit crank after it fails? I would check all of my battery connections you may have a loose ground either at the battery or at the engine. You may also have a bad starter relay located un the fuse panel under the hood

2006 chevy colorado passlock comes on and stays on, truck won't start for 10+ min. Can I disable this feature?


No, it can not be disabled.
The theft system is indicating a short term theft issue.
Have you added any "after market" remote start systems or alarms?
If NO.
Insert the key in the ignition, turn the key to run position ( do not start ) and leave it in that position for 10 minutes. Cycle the key to LOCK position, count to 10, then turn the key back to run position and leave on for 10 more minutes. After the 10 minutes is up, repeat the procedure (1) more time and the security system will relearn the PASS code.
Give it a try and let me know.
Regards,
