Re: '96-2001 hard start

I haven't heard of doing anything to the fill pipe, to remedy any problems before. I would like more info about this.

SCPI- Sequential Central Port Injection
AKA:
CSFI- Central Sequential Fuel Injection
CSEFI- Central Sequential Electronic Fuel Injection
SCFI- Sequential Central Fuel Injection
CSPI- Central Sequential Port Injection

SCPI is the type of injection system you have (96+) it has six centrally located injectors with lines going to each cylinder. The fuel is introduced in to the cylinder through a poppet valve in a sequential order, these valves can become clogged and cause performance problems.

Don't confuse this system with the 95- CPI (Central Port Injection) which is a "batch fire" system. It has a single centrally located injector that sends fuel to all cylinders at the same time, through six individual lines and poppet valves.
