i got a ls vtec in my teg good compression on head and block and my #1,4 cylinder do not run. i have checked EVERYTHING that has to do with sparks and fuel. both spark plugs are not wet i switched injectors and thats not the problem. please tell me whats left. valve adj?

 

Ecu??

Could have had a short and now its toast.

 

I agree. Its time to check the wiring.

 

check wiring where??? in the engine bay? i just did this swap so im not sure how it could fry the ecu. i have heard from a couple local people that the valves need to be adjusted and that they could be too tight. Now that seems logical other than the fact my car was just running fine on friday with my b20 vtec with this head...

 

Why are the plugs not wet? Do you know if the injectors are firing? How is a valve adjustment going to alleviate injectors that are not firing? Check for pulses at the injector with a multimeter while the engine is running. You may need a valve adjustment, but from what you have said, I do not think that is the root of the problem.

 

see if all the injector plugs are plugged in tight

That is really strange that they are not injecting fuel. Does the fuel rail leak gasoline when you remove 1 and 4? I'm considering the possiblity that there is debris in the fuel rail blocking those injectors. (Yes, this is a long shot.)

 

my car was running fine before swap and when i did the swap i didnt take injectors or fuel rail off. i checked the filters anyway and still nothing..it is very frustrating

 

come on H-T
