Well, I had some time yesterday to play with the car. The problem is..it'll crank for about 2-3 seconds..then start run for like a second, then flood out and wont restart(because its flooded)...I have a strong feeling that it is my timing, and rigth as I started to work on that...I had to leave for a night out with the other rx7 guys. A buddy of mine called from TX and I was talkin to him about it, and he said when he installed the CAS on his '91 SP motor from atkins, the timing was not right and was actually backwards..he called Dave at Atkins and he said that they must have installed the gear wrong? WTF...so I hope mine is not the same way, or I'll never figure out my timing! Also, I noticed the gasket wasn't seated tight with my ACV blockoff plate, so I feared air was leaking and that cuased hard starting as well..I took the gasket off and applied some RTF to it...seems to be holding up good now. What else could be causing hard starting?? TPS..CAS? All my vacuum lines are capped on the TB and I have no rats nest, etc...cant figure this **** out...

You have the MAS plugged in? Sounds like that or a bad vaccuum leak, I mean let's face it with rotary if it starts for 2 seconds then quits, no matter what the reason it's flooded.

Yea, the MAF is plugged in...I think the reason it floods so quick is because the timing is off...like, it sprays the fuel, ignites too late...then on the next cycle burns off what was left over, **** its probably firing the rear rotor when the front rotor should be firing and vice versa! It's annoying,lol...for all I know, the ******* engine is running on the leading plugs "wastespark" lol...

pressure sensor is hooked up?

Would that keep it from staying running??? damn..lol, but yea..that's hooked up too.

yes, you would have to hold that gas if that wasn't plugged in..

Good to know. It is plugged in though...maybe it's not getting enough of a reading...i have it T'd w/ my boost gauge and BOV since I have the ACV removed...maybe I should relocate the BOV to another vacuum source....

Where is the pressure sensor located? My rx-7 tries to start and it sounds like it almost startes, but then it just keeps cranking? Also, how do you time these things? I've seen the white mark on the pulley, but there are two of them. https://www.nopistons.com/forums/pub...1047683358.gif

dose your car gurggle? or dose it just try to start but wont? did you try doing a compression test on her

Compression is good, everything else is going good...starting new thread to explain, lol https://www.nopistons.com/forums/pub...#>/biggrin.png
