Ok. I am starting to get frustrated with my car. I have a 88 CRX HF with the stock d15 engine. It has about 150,000 miles on it. A few months ago I started having problems with it not starting sometimes. The fuel pump was not turning on so I had the fuel pump replaced, didn't help. I went to check the ecu and it isn't turning on when the fuel pump isn't turning on. Here lately that problem has been getting better and oddly enough, if it doesn't turn on, I can usually bang the steering wheel and it will turn on. I have changed ignition wires and the ecu and neither one helped the situation. Here lately I have been having another problem. After the engine is warm, the engine has been sputtering in low rpm's. It will only do it after I have ran the engine for awhile, and then let the engine sit for awhile (around 15-20 minutes). It has even been so bad that it has prevented me from starting my engine and keep it running. It will also only do it in low rpm's. Once I get it above 2k, the engine runs fine. Since this started, I tried new fuel injectors which didn't help. I have checked the ecu several times and it never shows any error codes. Does anybody have any ideas as to what may be wrong?????

 

Have you checked the main relay? I don't know if the hf's are like my si or not, but i took out my main relay, and resoldered all of the solder points. You can search here, and find out how it's done. It does'nt cost a nickle to fix, if you have a soldering gun.
