What is wrong with the car , when it turns off On the road and won't turn back on , when I try to start the car.

Asked by Feb 23, 2016 at 08:03 AM about the 2006 Pontiac Grand Prix Base

Question type: Maintenance & Repair

3 months ago, I was driving down the road and my
car turns completely off . and when I try to start the
car, it cranks Over but won't start, so I got a
mechanic that told me it was the crankshaft
sensor,and  then the coal pack had them replaced
and its not, now I got a new mechanic and it won't
even crank to start. The new mechanic hooked up
the Diagnostic machine to try to figure out . what's
wrong with it  and it's not reading any codes, at all
where do u think I should do to try and figure out
why the car won't start? The second mechanic told
me it could be a lot different things, it could be the
starter, fuel pump, A  realay,  electric problem,  fuel
pressureb Regulator, ect. Many possible things. I'm   
not sure what to do?  or where to start for that
matter? All I know that I need my car fixed  so, I
can have transportation to work.

I'd start with the coil pick up in the distributor, Electrical problems are a bitch, hard to find. An engine needs three things to start first is air, I assume that's not the problem. Then fuel -check if gas is getting to the throttle body. If not then it is fuel system-filter pump, etc. Next and sounds more likely is spark. Check if you are getting any spark at plugs, then trace it back. You can start throwing electrical parts on , which could get expensive if you guess wrong a lot. You need to find a mechanic that is good with the electrical stuff.

I think the first thing you need to do is find a mechanic who know how to diagnose this car. It could be a lot of things. You need someone who can narrow a little before spending a fortune throwing parts at it an hoping for a miracle.
