Re: F22 to H23 swap wont Start

check compression on each cylinder .. check timing, set at TDC - cam and crank
check to see if you have good spark

Re: F22 to H23 swap wont Start

compression, spark, fuel --- you need all three working properly in order to start your motor, nothing more nothing less. .. if it doesn't start, then check all three

Re: F22 to H23 swap wont Start

^ the only thing that comes to mind are Ground connections .. check to see if your ground contacts are good, the more important ones are near the thermostat cover and tranny ground

Re: F22 to H23 swap wont Start

the most common ground wire that everyone forgets during engine swaps (including myself) is on the thermostat housing. check to make sure thats on.

She's cranking, she just won't hold on to a complete start. We've replaced everything I can think of.

Re: F22 to H23 swap wont Start

I have the same problem. You might have to revert back to checking your timing again. Even if its one tooth off it could be enough to make it not run.

Re: F22 to H23 swap wont Start

We finally figured her out. We had another one of our boys come look and he noticed that our distributor was not in the correct order (go figure right???). Now I just gotta get my JDM H22 Vtec Head slapped on the New H23a1 Block. Any1 have advice on how to properly convert it..
