New Engine won't start

I just dropped a new preassembled long block in my 2006 Wrangler...when I went to finally try to start it, it cranked and cranked and cranked and cranked...and never hit. I yanked the dizzy, turned in a hundred and eighty degrees, and now it cranks and tries to hit every second or so four times...then cranks for about three seconds and does the same thing where it tries to fire up four times...any ideas? I know on a TJ the timing is completely computer controlled....so how can it be out of time?

But there's only two ways the distributor goes in since it's got a tab on the bottom of it instead of it being round...right?

Right ... but make sure that piston 1 is at TDC. Also, does that engine have a stock cam or aftermarket one?

Okay, and it's an aftermarket cam.

Follow this exactly and you will be fine ... clicky clicky

EDIT: You most likely will have to cut off the tabs from the dizzy to align it correctly. Thats what I had to do on my stroker with aftermarket cam.

Mine doesn't have a rotor though...I can't tell where it's pointing. It's a metal wheel it looks like.

2006 doesn't have a distributor - that's the cam sensor.
DON'T CUT OFF THE TABS! Otherwise you'll need a whole new assembly. Tabs are put there for a reason! The phase relationship to the crank shaft sensor is very important.

Get the manual - there's an important procedure to follow when setting the cam sensor.

An internet search may find the procedure.

I didn't even realize that your's is distributor less (I believe 2003+). I just assumed that it has distributor since you said distributer in your first post. Anyways ... this is what I found ... it is called a toothpick method. Try this ...

INSTALLATION-OIL PUMP DRIVE AND SENSOR


Clean oil pump drive mounting hole area of engine block.
Install new oil pump drive-to-engine block gasket.
CMP Pulse Ring Alignment





Temporarily install a toothpick or similar tool through access hole at side of oil pump drive housing. Align toothpick into mating hole on pulse ring.
Install oil pump drive into engine while aligning into slot on oil pump. Rotate oil pump drive back to its original position and install hold-down clamp and bolt, Finger tighten bolt. Do not do a final tightening of bolt at this time.
If engine crankshaft or camshaft has been rotated, such as during engine tear-down, CMP sensor relationship must be reestablished.
Remove ignition coil rail assembly. Refer to Ignition Coil Removal/installation.
Remove cylinder number 1 spark plug.
Hold a finger over the open spark plug hole. Rotate engine at vibration dampener bolt until compression (pressure) is felt.
Align Timing Marks





Slowly continue to rotate engine. Do this until timing index mark on vibration damper pulley aligns with top dead center (TDC) mark (0 degree) on timing degree scale. Always rotate engine in direction of normal rotation. Do not rotate engine backward to align timing marks.
Install oil pump drive into engine while aligning into slot on oil pump. If pump drive will not drop down flush to engine block, the oil pump slot is not aligned. Remove oil pump drive and align slot in oil pump to shaft at bottom of drive. Install into engine. Rotate oil pump drive back to its original position and install hold-down clamp and bolt. Finger tighten bolt. Do not do a final tightening of bolt at this time.
Remove toothpick from housing.
Install sensor to oil pump drive. After installation, the CMP sensor should face rear of engine 0° .
Install 2 sensor mounting bolts and tighten to 2 Nm (15 in. lbs.) torque.
Connect electrical connector to CMP sensor.

That should do it - it's actually simpler than getting a distributor in correctly. It's just a little intimidating the first time.

That little sensor does quite a bit - it not only gets the spark occurring at the right time, but it also gets the injectors to fire at the right moment - and it turns the oil pump!
