96 fleetwood been perfect until today, started it but wont run, continued to start it but only sputters after long start. No check engine light on or key fault light on either? Could that be a tell sign of something bad if dont start? What are things i should check first? Before i assume opti or fuel pump? Im thinking first check fuel pressure, spark at the plug and coil right? How do i check for spark at the coil and plug? And how could i check if the icm working? Any help and tips would be much appreciated.trying to do as much as i can by myself in the driveway.
