we changed the fuel pressure regulator, and it still won't start
If we put gas or carburator cleaner in the carburator it will start, the pump seems to be working too, it also has good pressure in the fuel lines, what could it be????
fuel injectors?

 

[sm=welcomesign.gif]to the Forum. Sounds like it could be a bad fuel pump. Have you done a pressure test? Guessing at the figures won't do any good. If you have questions about how to test it, use the 'search' function. I have outlined the procedure several times. Let us know what you find.
