She just doen't want to start
#1
NO GO she just doesn't want to start. The spec are
0.self-rebuilt engine. new mid housing due to old housing
inter water seal grove break off and fell into coolent passages. Which let water into rotot housing. other then that
everything one to spec.
1.compression of rotor1 -90psi rotor 2 -93 psi
2.fuel preassure from fuel filter 55psi
3.new plugs
4. checked the resistance on wires good
5.same thing with coils good shape
6.engine gets a spark,
used a timing light on both rotors to check
7. timing is on tdc
eccentric drive key lined up with marker on front cover and
anlge sensor lined up with mark.
8.angle sensor resistance checks good
9. fuel injectors resistance checks good.
10. new battery
When I try to start it up and adjust the angle crank sensor
it get a hint of combution with some smoke out the back, but it just wont catch. I heard some combustion
then is ussually gets flooded with fuel and then i have to stop
take the plugs out turn the engine over have a nice clound of unburned fuel loom around for a second. Then I let her drie and put some oil in her and try it at a different timing setting. but i never really get any where. With some advances i get a better hit but nothing to get her going. And they are usully no where near TDC. Thnaks for any advise you could give and thanks for the advise before.

I read that it could be air flow meter. I have a 90 miata also I could try and switching them out to see what happens.
next steps I’m thinking are
1. air flow switch if the are compatible.
2. Using a stethoscope to make sure the injectors are running well.
Even though I really can only get to the two of them.

I know there's a lot of thing that can keep it from starting but if everything was working before you tear down the engine, why should it has faulty parts now? I think the whole problem started when trying to start with timing problem, now it's fixed. Because of that, there's too much stuff in there (oil and gas) and nothing could fire that stuff (more over, timing is only roughly set). The fastest way I see to flush that stuff out, is to drag the car on the driveway.
The car wants to start but not strong enough to clear that stuff out. It's my opinion anyway.

SHE'S ALIVE SHE'S ALIVE sorta............
It worked pushing her with another car then poping the clutch worked. But as soon as I let off the gas she dies off. what should i do next. Is it an ideal control problem becuase when i got the car before i rebuilt the engine i noticed that she idealed around 1900 rpms. Also i'm getting lots of black smoke when she is running for about ten seconds. But ten seconds is about as long as I got her to still run.
