I would say the fuel pump is a good place to start. sounds like its not building up good fuel pressure.

to test the fuel pump/filter, have the truck off, then turn the key to acc/lights come on, but not the engine, some models you will hear a low gurgle sound, for a few seconds, turn the key off, then repeat the process again, then off, then start it, to see if the system is just needing more pressure to be primed...

Seems to work if you sit and wait. But its a bummer as who wants to wait when you want to get going.

I Have a 2004 Hummer H2 that will not crank at times. I will drive it then put it in park sit with it running for a short period of time. Shut it down for under 5 minutes then jump in try to start it and NOTHING. Lights and all electronics come on but it will not turn over. I hear a slight scratch like sound when turning the key all the way to crank. It's not the Battery, Not the Neutral Safety switch, Not the Starter or the Starter Solenoid. But After sitting for a little while it suddenly starts. We are about to replace the key ignition itself. It like maybe something is getting hot then cooling off or something. ANY IDEAS??

Did anyone find the real reason the H3 will not start and in ten minutes starts right up...If it's a factory problem it should be a recall...

I had the same problem and they think the problem is a temperature sensor that was sending faulty readings to the computer. It was thinking that the engine was too cold and sending fuel to the motor causing it to flood.

It was easygoing in your engine compartment open the fuse box look At your fuse box panel diagram and find number 66 fuel pump relay switch it for now with another one with the same part number on it, your hummer should fire up with a crank no start issue.bad relay.

I've had the same problem for 4 1/2 years on a 2006 H3! If you wait exactly 10 minutes, it starts just fine. Had fuel pump and sensor changed. Twice! Because they thought first one was faulty since I still had the problem. Then they thought it could be the ignition and/or the passlock. Apparently, the passlock is what thinks your car is being stolen and shuts it down for 10 minutes. However, they are each $600 and no guarantee that either is the problem and the car is out of warranty. Haven't done either. Has anyone with the 10 minute thing actually found a solution???

I have the same exact problem. I have a 2006 H3 with 65,000 miles on it and same thing happens. I go to start it up and it turns over but doesn't start. I wait exactly 10 mins and it starts right up. I don't think it's the fuel pump, I think it has something to do with the security system. The car thinks it's being stolen.

The ten minute wait period is defiantly security problem. When the vehicle will not start check the security symbol on your dash and if it is flashing then that is the problem. I have a 06 H3 and replaced the ignition switch and was better for awhile but started doing it again today. Another thing to try is take dielectric grease and put on all of the connections for the security and it might work.

I have a 2008, H3 Alpha, and for the past two years I have had a similar problem. 1. Drive Hummer, shut off, get out. 2. Return some time later, attempt to start..no crank, yet all dash lights illuminate and the accessories work. 3. Thinking it was a slightly discharged battery, the first few times I tried to jump start...with no success. 4. Like magic after 10 minutes it fired right up, as if there is no problem. I bought a new battery, had it in the shop three times...no diagnosis because I can't replicate the problem. One constant is that it only happens in cold weather. Any advice...

I have heard of one repair is to run wiring directly from the ignition switch to the Body control module for the security wring to eliminate the extra connections.The problem is cause by high resistance in cold weather.

It's a pass lock issue and it's costly, I ended up trading mine in!

I agree. It is the GM Pass-Lock system part of the ignition switch. I had the exact same issue and tried cheap online bypass to the pass lock system. The only true fix for the problem is a GM dealership maintenance department Replace Ignition Switch. Problem went away going on 2 years ago and still good to go. This should be a recall and we should all ban together for a class action suit against GM, for once again instalcentsling the faulty units in 2003-2008 H3 Hummer ... . My total replacement cost (in Hawaii) $450.00 and they have to re-flash your ECM-Electronic Control Unit (engine computer) to learn the new ignition.Just my 2 cents...

Mine did same thing was the battery would set off alarm and had to wait 10 min before start. If not check ignition switch may need replacement.

The problem, you are entering and starting the vehicle in a manner that makes the passlock think the vehicle is being stolen. Solution, lock the vehicle, make sure all doors are closed, unlock the vehicle from the driver side with the ignition key... the vehicle will start normally.

I had the same problem with my 2007 H3. It happened once, then about 6 months later, then about a week later, and then every couple of days. It took me a little while to figure out the problem, but with searching online I figured out it was the ignition switch. The pass lock system thinks the car is being stolen. I started noticing that on the dashboard there is a symbol with a car and a lock and that would flash red as well as a small light by the radio controls when the car would not start. After about 10 minutes the car starts with no issue. I had the ignition replaced and then re-programed for about $350 with a mechanic and have not had a problem since. When I was researching about replacing the ignition I thought that it might be a good idea to go through a dealership but they would not replace anything without diagnosing the problem themselves. Well, that was an issue because first of all I knew what the problem was and second of all it is such an intermittent problem. Anyways, hope this post helps others that are having the same problem.

Hi All, Thank you for adding your views here, this has been invaluable in getting me to a fix and solution. I have FINALLY solved this problem with help from a module i bought online. If anyone from South Africa is looking for this solution, please contact me as i have done this successfully, and can confidently offer my services. +2780.099.3361 Anyone technically minded out there , the NEWROCKIES solution solved my problem first time round. ** Just a side note, i also had a problem with the fuel relay, but only come to notice that it wasnt the relay itself, it was one of the pins that the relay plugs in to the was/ is faulty. i just made a quick plan with that, NOTE : this was separate to the Passkey situation of ten minutes a time ( if the little security light is flashing, then the passkey is your problem - If this is does not flash, and your car just swings over, then its your fuel relay etc.... Kind Regards, Kirwin
