1990 Convertible will not start after warm-up!
I purchased my 1990 Rx-7 about five years ago. After owning the car for about a year, I lost all compression and required a re-build. The car sat for about two years until last month when I had the engine re-built by a rotory specialist. After spending all my cash on the re-build, I thought I could once again drive my favorite car. The engine ran smooth for about a week. I have babied (not going over 5,000RPM) this thing in fear of another blown engine. When I was leaving work the other night, the starter died. I was only getting a 'click' noise. I had to hit the starter with a hammer to get it to fire up and get me home. I replaced the starter and cranked the engine up. No problems, it started right up. I warmed the car up and drove it around the block a few times and parked it. I waited about five minutes and decided to test drive it again. The car was still warm and at normal operating temp. I cranked the car and it wouldn't start. I tried it again for about ten seconds, still nothing. I gave up for the night and tried it again in the morning. The car still would not start. I tried to start it again, but this time I held the gas pedal to the floor. This got the car started right away. I also have done the de-flooding procedures about a hundred time now and it doesnt help. So heres the breakdown:
1.) new starter, battery cables and terminals. Un-flooded several times. (just in case.) New NGK plugs and wires and new oil. Radiator flushed as well.
2.) car will only start when cold. Will not start after warmed up.
3.) Car will only start when cold and accelerator pedal is held down to the floor.
4.) After it is started, the car runs great. Great acceleration and smooth idle.
5.) If I turn the car off when it is warmed up and try to start it within an hour, the car will not start.
6.) Car is getting fuel and spark as well.
I really am stumped on this one and it sucks because I just paid 3,000 to get my dream car back and ive only gotten to drive it for a week! Any help would be awesome! Thanks in advance!

I'll give it a shot. Anything at this moment is better than nothing. Where would the adjustment be located if you don't mind me asking? Thanks for the tip.

mine does this because my thermowax is off from just old age. I got it closer to spec and it starts pretty good most of the time when warm, which it didn't used to. I'd check that as well.

okay, so I tried the TPS and THermowax trick, but no luck. Now, the car will not start at all...cold or hot. I began to breakdown the basics in search of an answer. I pulled the fuel filter and turned the key. No gas at all. The fuel pump is not working. Does the pump activate when the key is in the "on" position? Im not hearing noise either. Please, if anyone could help. Im running out of money and ideas. Thanks again.

I slightly (barely) touched the TPS. No results. Now, I have changed the fuel filter, which was filthy with brown and orange rust type stuff. I took out my fuel pump and connected it to the battery. The fuel pump works. I re-installed the pump and tried it again. Now there is no power to the start up. The amps on the meter read '13.' It seems like the battery is dead and cranks really slow now. I had the battery on a charger in-between fiddling with it, so it should not be dead. I tried 3 other batteries and still no power. Im really lost now and im about to sell this car for cheap. I paid 5,000 for the car five years ago and have spent over 5,000 in reapirs. Maybe it's a lemon, but im sick of repairing this car and it has never been on the road longer than a week due to it breaking down. This will be the third re-build if thats the issue. The car is bone-stock becasue I never have any money to upgrade the performance becasue it's always breaking down. I take care of the car: tune ups every 3,00 miles. I carry oil in the trunk( for adding between changes) and so on... Iv'e only redlined the thing once in my time owning it. This is a love/hate relationship, but I can't afford to keep this thing on the road. I preach to my friends about how reliable rotaries are and I feel like im lying to myself over and over again. Sorry RX-7, but maybe when I make 100,000 a year, I'll buy another one.

1.) recent rebuild. ~12,000 miles on it. (this was the second rebuild in 2 years.
2.) new starter installed.
3.) new battery
4.) new fuel filter
5.) NGK tune-up
6.) oil change/filter changed
7.) new terminals/cables for battery
8.) coolant flushed and re-filled
9.) fuel pump tested ok
10) now, car lacks power on start up. Seems like battery is dead, but tested 3 others and it does the same thing.
11.) checked all wires and grounds...they are fine.
does anyone have an idea?
the car ran fine until last week when the starter crapped out and was replaced. After the starter was replaced everything went downhill(no hot start, no power on start-up now, no fuel.)
i hate my luck! any help would be awesome! thanks everyone.
ps-ive checked all the fourums on here and it seems like the compression is gone fo no reason.

I have this same problem. 88tii. In the morning it will start fine after its been sitting all night but after it gets warm when you shut it off it hard to get it started. You have to hold the pedal to the floor in order for it to start and it starts rough. The car also hesitates all the way threw the RPM range. It also misses a little at idle and it idles at 1000,1100, 800 sometimes its just all over. Tommarow im trying to figure this thing out i wonder whats wrong with it.
I got the car today its a all orignal 88 T2 orignal owner never seen winter and hardly rain. Its black mint! dude im working on it for paid $800. what a STEAL!

okay, so I've been tinkerig with my rx7 for a month now trying to get this car to start. Yesterday, I went to crank the car over and it started without problem. Its been running fine since with no signs of problems. I have no idea how it fixed itself, but im glad its running now. I wish I knew what I did so if it breaks down again, I could fix it. I guess... problem solved with no evident cure. thanks to everyone who tried to help. I appreciate your suggestions. thanks again guys.

okay, so my rx-7 has been running great and I recently had my brake system maintnenced by Tire kingdom. I was driving home and went to stop at a light when my brake pedal went all the way to the floor. without hesitation, I pulled the e-brake. I let the car idle and noticed that a thick white smoke pouring from the exhaust. This was not the normal rotary smoke, but a five-alarm fire type. Worried I blew my engine or something, I rushed to Tire Kingdom, using the emergency brake. Smoke continued to pur from the pipes and halted all traffic on the way. So heres what happened: My master cylinder exploded for some reason and the brake booster vaccum sucked all my brake fluid into the intake, thus creating a bastard fuel mixture of mass disgust. Not to mention all the brake fluid on the exhaust manifold getting sucked into the intake. So, If this happens to you, now you have somewhat of an idea of whats happening.
