have you checked to see if you are getting any PCM error codes? Not every error lights up the CEL, some are just stored until checked.


Have you checked your coil?

Have you checked the continuity and resistence on the plug wires?

Have you put a spark checker on the wire end to make sure it is getting juice to the plug?

Have you checked the plugs to make sure they are OK?

Did you put a noid light on the injectors to see if they are firing?

Have you checked the compression for the cylinders and/or done a leak down check?

 

I have done all that except for a noid light i used a test light but somebody said that dont work and i havent checked compression
