Won't start help please..
 

I have an 02 4.0 Laredo I've changed the CPA timing chain and cam sensor but its still not starting I've done tdc 3 times and it keeps firing through the throttle body do I need to reprogram the CPU? Or what please help..

Flames from the throttle body mean either the ignition timing is off or the firing order is screwed up.

So I've turned it 180 degrees I've turned it every which way on the cam sensor but still nothing I've put it top dead center and same thing happens.

Top dead center compression stroke ?

When u did the chain u double check your timing cause if thats even a tooth off youll never get it right

Yes I used a ruler and even a second opinion but its doing the same thing..

Could the map sensor cause this?
