My name Is Pete I recently purchased a 1991 rx7. Upon purchasing the car I knew that the dreaded 3800 hesitation had been doing its dirty work but after driving it home I discovered that one of the oil injection lines was broken off close to the OMP. I replaced the line and while I was in there I cleaned off the grounds I could find. Then after I put it all back together I noticed that the OMP was not pumping at all so I ordered an OMP block off plate along with the injector plugs. I installed it today when I finished I looked at the gas needle and decided that since it was a hair above the E line it had atleast a gallon of gasoline in it. I added 8 oz of valvoline 2 cycle oil and 5gallons of fresh gasoline. then came the moment of truth I attempted to start the car and smelled gasoline I found that there was a busted O ring on the top of one of my injectors so I replaced that note that during this time the car would start go up to 3000 rpms and die every time. after I replaced the O ring I tried to start it again I couldnt get anything out of it so I checked to make sure everything was hooked up. I found that I had left the throttle body unplugged so I plugged that back in and tried again. This time I had to pump the gas peddle as fast as I could and after 30 seconds or so it would crank and go up to about 600 rpms and die one thing I noticed at this point was the smoke Im not exactly sure if you would consider it alot of smoke but there was a small cloud of white with a slightly blue tint to it everytime I could get it to crank that little bit. I checked for anything being unconnected again and again I could not find anything and now I cant get it to crank at all. I thought it might have to much premix so I added so more fuel to lean it out but nothing Im lost

you probably still have a vacuum leak or afm unplugged.

Removing the omp on a s5 will put it into limp mode, but that doesn't really sound like your issue. Check for vacuum leaks real good, put some good gas in it, make sure everything is hooked up and plugged in.

Make sure those oil injector plugs are sealed good, and all your injector o-rings are in good shape too.

Thanks everybody I tried to keep it short I`ll quadrupple check everything I do have one other question though the vaccum lines that go to the oil injectors I assumed the right thing to do was to block them off, was I right?

Also the car was already in limp mode I figured after blocking the OMP off as long as it was still plugged in it would run the same way atleast, was I wrong?

I just thought about this too, under the intake manifold there was a plug in the shape of a circle it was black it looked like an electrical plug of some sort. I do not remember unplugging it and I could not find anywhere for it to plug in any ideas as to what this is?

Air flow meter?

If your OMP is dead, it's still going to be in limp mode.
