07 H3 engine will crank but won't start up

[Burnoffski]

Hello all,

Went out to start the H3 this morning to head in to work and she will turn over but won't fire up.

Haven't had any trouble or issues at all up until this. I am thinking maybe fuel pump but I need some help and guidance on what things I need to check out and possibly where it's located so I am not just guessing and throwing money at the problem with no results. Any and all help is much appreciated!

Pump is in the tank. Lay down with your feet under the truck...and kick the bottom of the tank (very hard). Believe or not...I've used this trick several times to get home. It somehow jolts the pump into working...like a defibrillator.
You'll still have to fix it but this can save you a tow bill.
Of course...it could be something else entirely.

Thanks for the reply and suggestion. I am at work now but I will definitely kick the shiz out of the tank this afternoon when I get home.

I have been reading a lot of posts about H3 not starting and I am also wondering if it might be the passlock so I will also be looking to see is the dash light is flashing for that too.

Anybody else that has any suggestions for me to look at/check out let me know.

When you turn the key on listen for the pump to hum, or find the shredder valve for the fuel line remove the cap and push the small pin in the middle with safety glasses on push the pin to see if you have fuel pressure.

Thanks for another check point I will check this out too! Will this shredder valve be on the fuel rail were the fuel injectors are?

Pass lock very common. I get it from time to time. Just wait 10 mons until it isn't blinking on your dash before dumping cash in it

Well first thing I checked was the passlock light on dash and sure enough it wouldn't fire up just turn the motor over and when I stopped trying the passlock light was flashing and the CEL too (which has never been on before).

Do you leave the key turned to on or ACC while you wait the 10 min or not? I waited the 10 min still just turns over no fire?!?!?

Any thing else I can do other than wait 10 min?

My 07 has done this in the past as well. Pass lock. Check your battery terminals especially ground. 10-15 minutes with key removed.

Waiting isn't changing anything. I checked them earlier everything seemed in order but I'll check them again.

Woke up decided to give the H3 a try and I fired right up which is good but now the question is when/where will this happen again?!?!

I'm going to go with Passlock too. The way to confirm is two things: 1) security light on the dash flashes and 2) after 10 minutes you are (probably) successful in starting your H3. I
