It all began when i was coming home one night and the car just lost power and kept loosing it till it finally died in my driveway. The car will crank but not start. I got it from a guy who blew the origianl and had this one put in with a T4 turbo and bigger injectors. The car has nitrous kit hooked up but he said he never used it and i never did either. I had the altenator tested and its ok. I also replaced the battery, sparkplugs, and fuses. Oil has been changed and ratiator flushes and new coolant put in. I believe it may be flooded or the coilpacks have gone bad. Please someone help.

I think the first thing you should think about doing is a compression test on the engine. Hopefully you know how to do a compression test on a rotary engine. The best way is with a compression tester built for rotary engine's....but there is ways to use a normal compression tester.

Good Luck

Suggested Repair

Perform a compression test on the rotary engine, preferably with a tester designed for rotary engines.

Conversation Summary

A 1988 Mazda RX-7 with a replacement engine, T4 turbo, and larger injectors lost power and died, then cranked but would not start. The owner had already checked the alternator and replaced the battery, spark plugs, and fuses, and suspected flooding or bad coil packs. The expert recommended starting with a rotary-engine compression test.
