Hey Everyone,

I Just Put In A New Stereo System In My 7's, And Now The Car Won't Start. I Checked All The Fuses. All Good,
I Checked For Spark, It Is There.
I Check For Fuel At The Fuel Pump, By Disconnecting The Fuel Line. There Is Fuel.
I Check The Main Reley, It Works.

What Else Can I Check.

And How Do You Check For Fuel At The Injector? Do U Have To Take Off The Intake And Tb, Please Help

 

does the starter crank?

 

i guess i should have tell you guys that. well. the engine cranks. just no signs of firing. a little puff of smoke or just foggy looking smoke is around the tip of the exhaust, after i try to start it. the two plugs that i can get to looks dry. i clean them up with wire brush.


please help.


i am going to reset the ecu. and see if that changes anything. or should i pull a code on it first??

 

when you hooked up the the new tunes how where and how did you hook up the wires to pull current form the car ( you might be pulling to much current form the battery at start up) this could cause the coil not to have enough electricity to fire the air fuel mix.

oh what other mods do you have done to the car?

 

^^ easy way to check this, disconnect your sounds from the battery and see if it starts. You may need a stronger battery if you're running a costco one

 

o.k. i am going jump the battery with another car. to see if that will start it.
the amp is hook up at the battery, but it is not on when i try to start the car.
the radio is hook up using the stock wiring of the bose system.
i am thinking maybe the battery is a little too low to start it. because the car been sitting there for 3 weeks, and i did use the battery to test the stereo system, and not run the engine to charge up the battery.
i will try it tonight and keep you guys posted.
thank you for the input.
and keep the idea coming, cause the sound system does no good if it stay in the garage.

peace out

 

Pop start it .... kidding...good luck
