New engine won’t start

[Bt Doctur]

I was off a little bit, use the red line when installed

 

[Dmaxx85]

Yes that’s the problem I’m having where the red line is above I cannot get it to go in there on the cam gear. It’s to either side and will not go.
Mill try again though

If the rotor is a tad more CCW, can you just turn the base to the rotor?

 

[Dmaxx85]

Yes the base then will line up but the cap will not go on because it’s hitting one thing or another and yes the rotor goes all the way in there and is fully seated onto the oil pump driveshaft.

basically It won’t even drop on the cam gear In the position I need it to for everything to like up

 

[Dmaxx85]

Do you guys really think after the hours I’ve spent trying to get this thing to drop in where I need it and hitting the teeth either way of where I need it that I am just missing the tooth? Plan and simple?

Now could I ever drop it in close to where it has to be then rotate the engine around (or rotor) to the spot where the base will line up and the cap will fit???? Just to get the rotor to line up with the 8 on the base?
Or would I then be a tooth off?????

I think your off just a little from TDC. There is a service bulletin in which an LED is connected to the crank shaft position sensor to make sure its fully on TDC. Been looking for it for some time (I even remember making pics to post here) and helped Fun Times to get it listed, but cannot find it. Will continue to look

THat would be very nice to have.
Like I said earlier in this post it seems like once the #1 intake valve closes it seems like it’s a long way back around on the harmonic balancer to line the the timing marks up to zero.

i watched a YouTube video and once the intake closed 0 was around 11 o’clock and he had to just bring it over to 1 o’clock where the timing mark is

once my intake valve closes my 0 is around 5 o’clock
and then obviously have to bring back around to 1 o’clock

Took a bit to find but I believe i just found it....It starts here on post # 46 but you posted it fully on post # 48.

Many thanks FT

and now I know why I couldn't find it, its under emission controls :facepalm:

the flat of the base must go as shown, against the intake, the screw position I posted with the red arrow just to the right of the bracket, thats where it must go.to install the screws (post 58) and have the cap just fit in its position, set the base there and adjust the rotor to fit within a few degrees of the small number 8 . If necessary move the oil pump drive to match the bottom of the dist drive gear.

 

[Fun Times]

See if maybe the photos and/or links below help give you an visual of the typical placement these distributors like to be placed in to connect up properly.

Notice the CAM sensor rests in the 8 o'clock position while the flat part near the number 8 is just almost to the 12 o'clock position of the very near center of the intake manifold all while think of looking from the rear of the boat/engine looking forward.

Also zoom in real close in the following link to see how all the screw component positions, cap cut outs, etc. are placed off of the intake manifold, etc....,

If I wasn’t a TDC that wouldn’t stop the distributor from dropping on the cam gear I need it on?

Agree, that should only be caused by the oil pump drive is not in alignment between dizzy and slot.

 

[Dmaxx85]

Well I believe I got the distributor lined up and everything back together. Unfortunately I wasn’t able to try it . I have a blown fuse or something somewhere because I lost all power except to the trim. I didn’t have anymore time tonight. But one thing at a time I guess . Any ideas what fuse? Off the starter somewhere

I’ll get the testlight out tomorrow

thanks for the help

 

[alldodge]

Look for the 20amp ignition fuse, its on the red/purple wire feeding the key

 

[Dmaxx85]

No power to the ignition fuse. Power to the starter and not the circuit breaker on top of the motor no power to the alternator.

Shouldn’t I have power at the alternator?
say I shorted something out working on the distributor which is very close to the power feeding the circuit breaker.

What a deal this has been. It’s been 7 weeks since I cooked the old motor

 

[alldodge]

Think you blew the 90 amp fuse
Looks like the pic and is attached to the starter post. The fuse is designed to protect the ALT but most times the Red/Purple is also atted to it which feeds the 50 amp breaker and everything else. If the fuse is blown, suggest attaching only the Orange ALT wire to it and attach everything else to the starter post (they have their own fuse/breaker)

 

[Dmaxx85]

It’s def the 90 amp fuse on the starter. Not a good feeling!

Well l wanted to try it so I bypassed the fuse like you said and it’s still wouldn’t run. I would say it almost started then it was popping. Sure seems like I’m 180 off still

Im sure I was at TDC I’ve done it almost 20 times and finally felt like I truly had the rotor and gears lined up but no luck yet.

May have to call in some help

 

[Dmaxx85]

Why wouldn’t I be able to turn the crank over with the breaker bar anymore? The bolt for the harmonic balancer just wants to tighten. All the plugs are back out and the belt is off.

Turns over by the starter

 

[alldodge]

You shouldn't turn the motor over with the crank bolt, it could snap off, then there is real problems. Also this should be a left hand motor so bolt would be loosening

If the motor will not turn over by hand with the plugs out, but will with the starter, I would remove the drive. The drive might be causing the issue
