I recently replaced the fuel injectors in my 89 rx-7 and am having trouble getting it started. It will crank like it is going to turn over but it doesn't. After 20 minutes of cranking it may come on rev to about 3500 to 4000 rpms then back to 0 and turns off. I am not sure what my problem may be. I had read somewhere that it may be my fuel pressure but I am clueless.

 

did you repalce the gaskets/O rings when you replaced the injectors???

why did you replace them??? Bigger injectors will just cause flooding or other poor driveability unless you have sufficent engine mods to accomidate them.

 

I replaced the o-rings when I replaced the injectors but not the gaskets. I though that the injectors that I replaced the old ones with are the oem ones. So I don't think that it is getting to much fuel but I am not sure. Are there any modifications that I could do that would maybe help ge rid of this problem.
