Sounds like no compression

I have a (actually 2) 1988 RX-7's with 13B engines. They are both doing the same thing. First one car, now the other. It was running fine when my son decided to change the power steering belt. He did, but didn't tighten the belt enough and when he started it, the belt smoked and he turned the engine off after maybe 30 seconds of running. The car has not ran since!!!!! I pulled the plugs and disconnected the relay above the gas pedal and coils like a mechanic told me to do and spun the engine until nothing came out (only a little came out of one plug hole anyway). I put the plugs back in and connected the plug wires and spun the engine with the starter. It spins, and sounds, like a engine the has no compression. I then connected the relay and still the same thing. I cannot see any loose wires or hoses or anything else that would prevent the car from running. And I really can't figure out why it sounds like there is no compression. CAN ANYONE PLEASE HELP ME???? I would really appreciate any help that I can get from anyone who has had this happen to them or knows what's wrong. Thanks.

Push start the car. Get it going like 4000rpm in first gear with the key in the "ON" position. It will start sooner or later.

It's flooded. Search for "flooding". Push starting is recommended only as a last resort option.

Yeah, but I would rather push start then use ATF

Thanks to all 3 of you for your great advice. I went to the "flooding" posts and found that you have to push the pedal to the floor while cranking with the plugs out, etc. I didn't do that. I will try that, and if that fails, I guess I will try pushing it ( it is at an auto hobby shop on an air force base - Im retired - I'm not sure if they will let me push it.) I had an old 300ZX that had to be pushed or pulled to start if it sat more that a couple of days, but you had to push it about a mile or 2 to get it running. Anyway, thanks again. I'll try what you have told me and let you know what happens.

Don't use ATF. Use regular 10W-30.

go to

http://2ndgenrx7.freeservers.com/techmaster.html

under 'unflooding'

Look at "complex unflooding procedure"

Use regular oil as Aaron suggests (it's thicker than ATF)

Thanks for all of your help. I am on my way to the base now to try what you have suggested. I will let you know the results when I get back home. Thanks again.

Well, I tried everything (except oil in the trailing plug holes - try that tomorrow I guess) to no avail. I unpluged the fuel pump, took out the fuse, removed the plugs and wires and cranked the engine about 6 times for about 15 seconds each time. Put brand new NGK plugs back in and cranked the engine to burn off any fuel that may be remaining. That's when the starter quit working. At least I think it's the starter. When I go to start on the ingnition switch, everything goes dead. I disconnect the positive battery cable and everything is fine again until I go to start. Same thing. At the same time, the last time I cranked the engine, it sounded the same as before. The car has 267,500 miles on it, but it always ran fine up to the point that my son replaced the belt and it started flooding. (the plugs - the new ones - were wet when I took them back out.) ANY SUGGESTIONS....I'M ABOUT TO GIVE UP.

DONT GIVE UP!!!

The reason you turn the key and the lighs go out is because your BATTERY CABLES ARE LOOSE!!!

You are going to have to either do the complex unflooding procedure, or push start.

hit me on AIM or Yahoo instant messenger, or MSM. I will walk you through it.

Just push start it. You will have it running in under 4 blocks I bet.

Alright....take the battery cables off and put them back on. Now next to the battery on the drivers side coming off of the positive cable I believe...there is a small black wiring harness. Check that out to make sure its not getting pulled or its loose. That tends to happen and can cause exactly what I believe you are saying. Let me know if thats it.

I want to sincerely thank everyone that responded to help me. I pushed the car (less that 4 blocks, lol - DrOx you were SO right) and got it to run. It is now running perfectly again. I still have the battery/starter problem, but I am pretty sure that the starter is bad. (I always tighten the battery cables, it's not that -- and they are clean). I will work on that when I get back the end of next week. My son can at least now drive the car by bump starting it whenever he shuts it off. He will only drive it to college and back home until I get back, so he should be o.k. Thanks again for all of your help. I am very happy.
