Hey Guys,

Has anyone ever seen the injectors staying open after the car is shut-off. I am having a TERRIBLE time tuning the hot start on my new motor. Once I start cranking, it will NOT start until I hit flood clear mode. I have had the cranking PW as low as 0.5 ms and up to 3ms. Always the same behavior. I am using a cold cranking PW of about 9 and it fires and runs nearly instantly. I just don't know what else to look for. It is a SBC with port injection and 42 lb/hr injectors.

Can anyone offer me some advice? I am getting quite frustrated.

Hmmm, I will look into the part about the injectors and MS being on the same relay. I thought thats how I set it up but may be mistaken.

Thanks a lot Lance. Its great to get a direct answer quickly. I will post once I check it out.

Just to let ya know, you nailed the wiring Lance. Due to engine problems, I can't try to start it now, but hopefully it is cleared up.

Thanks,
Caleb
