Istalled new crank shaft now it won't start. Exhaust coming through the carbuerator and muffler.
Pull it apart again and reset the timing as you are out 180 degrees . Place the piston on top DC with the valves in the valve rock position . ( exhaust nearly closed with inlet just starting to open) This will align the timing marks between the crank gear and the cam gear.
Testimonial: "I timed it this way still will not start i am not doing something right"
the other things that will do what you describe is that the spark from the flywheel magneto is out .( Key missing from shaft) valve clearance is out , valve bent , bad valve seat. . Check the position of the flywheel when on TDC firing as the magnet part should be around the coil bridge laminations

Sounds like you may have gotten some debris in your exhaust pipe or something was clogging your muffler. Maybe the innerds of you Catalytic Coverter went and got stuck or the innerds of your muffler gave out. That would be the only few things I could think of to cause something like that.

Sorry..... 1 notch off is just not good enough. It has to be exact , then if it doesn't run start looking at other posibilities.
Remember that the camshaft turns twice eash time the crank turns once. The distributor rotor works off a gear on the cam.
Your rotor could be off a bit , or it could look exactly perfect the way it was when tou took it out , and still be 180 degrees off.
You have to get your engine to "top dead center" and make sure everything is the way it should be.
A timing chain ( or belt ) can cause permanent and fatal damage to the valve train and pistons in motors that are "interference engines" Find out weather yours is. In a non-interference engine , the clearance between the valves and the pistons is large enough to alow them to move out of time without crashing into each other. An interference engine is not so forgiving.
The fact that your engine cranks makes me hopefull that it is a non interference engine , and that damage has not been done.
Try to find a haynes manual for you vehicle , it will walk you through the steps for most repairs.
SOURCE: i put in a new cam shaft sensor and the engine
yes...replacing the cam sensor is just like a distributor
however, additionally, you need to reset the timing via a scan tool
SOURCE: 2000 ford explorer ohv 4.0I replaced head gasket.
Do a compresion check, if Ok then timing chain is ok, try some throtle body cleaner trough a vac. hose while cranking if stars, fuel pump is out, another way if you have no codes the most poss. cuase is your fuel pump, check press is gauge handy
