just rebuilt 96 4.0....no start....

[gungeek]

....I know the Haynes books are essentially staeming piles of excrement, but that was the only source I had when doing the rebuild for torque, oil clearances, and Timing.
I set the gears dot up dot down like the book said to, now no start after install.
To be specific, crank gear dot is up, cam gear dot is down, used a staight edge and square to assure alignment.
The sensor that goes wher a distributor should rightfully be, had to be rotated and pushed down/picked up endlessly to reinstall on the cam spline and oil pump drive rod.
I kind of assumed that rotating the gizmo was ok since it probably only times spark in a loop with the thing on the front at the balancer determining #1.
While cranking now it wheezes and acts like any engine with a real distributor, installed wrong.

SO what did I screw up???
Thanks for any help.

The camshaft sensor is very particular about where it needs to be. So much so they make a special tool for it. Did you use that?

 

[gungeek]

I did not use a tool

I guess it is more than likely way the hell off then. What to do now....
Thanks

Set the engine to compression stroke TDC on cylinder 1

At this point the flag on the rotating shaft of the cam sensor synch drive should be just entering the sensor gap, located in the cap. Think of it as a rotor. This eyeball method will be close enough to get the truck running, if it is indeed the problem. However, you must align it properly with the special tool.

Loosen the synch drive lock down tab and rotate the unit until the "tool" slips into place, then tighten the lock down tab. Re install the sensor cap and you should be good to go.

Thanks for the help guys

Looks like looking for a tool is the next step, At least I don't have to tear out all the front junk and remove the cover.

have you checked fuel pressure? Just curious
getting at the cam sensor on a OHV 4.0L = PITA! I put a 97 engine into a 95 and I had to swap sensors after I put the engine in because I am retarded, ended up removing the upper intake again....

Fuel pressure seems fine

I may very well have to remove the plenum...but that's OK, This time I was the retard....My brothers truck, busted down in MD for oil pressure problems, thought I could just flip the engine and replace pump and bearings......WRONG.
The pickup had a pint of black snot and boogers on it, so I pulled a valve cover and BINGO, the upper engine was choked with carbon chunks, cooked over time into wet anthracite coal.
I asked my Brother when he yanked out the sensor..."did you mark that thing, location to block, location of gear?" Nope. Lesson learned...watch, don't help.
New heads to replace the cracked ones and everything else cooked and cleaned, now together and in and...here we be.
Bottom line...ran fine, so just play find the tooth and rod game...then it should start and my brother can go back to NC.
Love my brother, but 2 weeks waiting on parts is tooooo damn long for him to be a troll under my stairs. NC needs him back.

CHeck the cam sensor drive gear real well, as it drives the oil pump

 

[gungeek]

Did that before...

...it was randomly plunked into place. The Oil pressure problem was due to accumulation of carbon renderings filtering down from the top of the engine and clogging the screen.
The cracks in 5 of 6 combustion chambers allowed flame to be exhausted into the valley where it cooked the oil....nice heads ford, Thanks.
