Hello I have 2007 hummer h3
The car will crank for long time then it would start we took it to the shop and they said the fuel pump not giving pressure so we replaced the pump now good pressure but now the car is not getting any spark! The shop said it did that after they scanned it. The car have that pass lock disabled and tuned from super module. We looked everywhere and we don’t k know why it still didn’t have spark and doesn’t want to start! The car have after marker remote state and security system since we got the car and had no problem! Please help me we been without a car for days !!!

 

they need to check the voltages at the coil packs. the harness to them might have a break in it. also need to check the crank and camshaft sensors and the harness also going to them.

 

I told them that and they said they checked all that already! it happened all the sudden first it was crank for long time before starting and now like crank but no start the coils are like new and everything came back normal

 

You got misdiagnosed/charged for a new fuel pump and now it won't start? Simply ask for your money back and find a new mechanic!
Where are you located?

 

no the pump was putting low pressure anyway and it was acting up so it needed to be replaced anyway. But even after it’s replaced now the car all the sudden not giving spark. They think it’s the aftermarket remote starter security system . I am in Jacksonville Florida

 

the wiring to the coils and the crank and cam sensors are known to get damaged on the GM I5 motor

 

they checked that already everything is good

 

have they checked the grounds going to the PCM?

 

No, the fuel pump was still good, yet you allowed your mechanic to throw a part at it, and now your H3 is nothing more than a lawn ornament.
Take a look back at ALL of your previous posts, hopefully you can learn something, and find a new mechanic.

 

yes they said they checked that and it’s good
