1995 5.8l. Starts sometimes.. mostly in the cool mornings or cool evenings... sometimes cranks but won't start.. mechanic buddy said something is causing injectors to NOT get power hence they don't deliver fuel. Lil help please.

 

Have you checked the fuel pressure and/or electrical connection at the fuel pump to make sure that it's getting proper voltage? Could be a damaged wire somewhere. There is currently a thread on it in the main forum.
