Another rebuild wont start
Hello, everyone.
I'm really having a hard time getting my rebuilt motor timed, I have a haynes and i still cant get it going.
I've check everything twice and its just wont start, the most i get is a sputter or back fire.
Any suggestions?

I found a thread one time that explained how to set your timing... It said;
"Just set the timing manually, I had a timing issue, set it with a light and it was still way off ( Definitely my fault) but I found it you set it this way it is much easier and accurate.
There is a little yellow mark on the Eshaft pulley closest to the front cover. Line this mark up with the little pin on the front cover above the pulleys.
Take out the CAS and line up the marks on the gear and housing.
In order to keep the marks lined up when you re install the CAS take off the top cover (two screws) and hold the gear with your fingers so it doesnt move around when you install it.
Bam, timing is set"

Did you try the deflooding procedure?

Heating the plugs just evapoates any fuel off of them.
If the engine was built with used irons and housings, compression will be very low initially. If you are sure everything else is OK, then a push start with another vehicle always works.

You said, it pops or backfires when your trying to start it. Mine did that too. I checked as much as I could with the timing and I think that timing on a rotor engine is too easy compared to piston engines... It's so easy, you worry that it can't be that simple. Even if your timing was off, it would still run, just kind of rough. I think that you should check fuel systems and vacuum lines. My fuel pump turned out to be not working at all. Now that I replaced the fuel pump, it'll start but it won't stay running. I think I have to check on the fuel injectors... You might be on my same path...

i thought the injection shop was jerking me around when i sent in a box of 16 injectors and only 4 were working and one was semi working, the others were all dead. i verified this with my injection test stand i built because i figured they were full of crap as they all ohm tested fine. all the ones he said were bad were in fact jammed up with old dried out fuel from sitting around on the shelf for months/years.
i have been seeing alot of injectors failing during rebuilds recently. if they have sat open to the atmosphere for any decent amount of time they will dry out and become stuck closed.

^ Couldn't agree more! The last 4 times I've helped someone with a rebuild, at least one injector on every engine has been bad. These injectors are are old, and have been baked, sat and abused for a lot of years.

they were still sercivable, i put them in a cleaning solution and cycled them for a few hours and they came back to life so i wouldn't pitch them. but in those cases you need to find a shop that actually cleans them and not simply test and do a quick flush on them as our local shop did for mine.
witchhunter, RC engineering and cruzinperformance all clean the injectors and give before and after results. soon i should also be doing injector servicing in house.
not that this is definitely the issue but something to keep in mind.

Damn, I just seen this and was about to chime in till I read the final post. Pull/push starting is usually the method. Glad to hear you got it started though.

Just about to give up hope. I guess the starter just doesn't turn the motor fast enough or its sat for so long. I had to repair my OMP lines and make a gasket for my EGR block off cause its was idling rough. Time will tell though.
