I have a 90 4.3L with throttle body injection that doesn't start once in a while after sitting over night. once it does start in the morning it starts all day. It turns over but doesn't get gas. The coil is good , the module is good , the fuel pump is good. doesn anyone have any suggestions?

 

Check for fuel and spark and post your findings as to which one you are not getting.

 

There is no fuel squirting out of the injectors
