Hello,

About 2 weeks ago, I replaced my spider injector unit as I had been getting multiple misfire and cylinder 4 misfire codes. The new unit worked great for about a week, then it began to act up. It takes quite a few cranks to finally start during the day, but if it has been sitting overnight it starts just fine. (I haven't had any engine misfire codes since its been replaced).

I have been led to believe that this is a common problem with a leaking spider or pressure regulator. Before I tear it apart (again) to find out whats leaking (and if the replacement spider was bad), I was wondering if there was anything else that I could have screwed up while replacing the spider, or anything else that might be causing my issue.

Thanks ahead of time for any advice on this issue.

 

Also, forgot to add, the replacement fuel injector spider is a "Central SFI Conversion to MFI" unit.
