Some of them use a mechanical version of the VP44...I believe it was the VE44...and it is suseptable to the same things the VP44 are...the only difference is that the mechanical lift pump tends not to fail like the electric versions do.
And the 12 valve mechanicals are 1989 through 1998.5 . And as stated by these guys, no chips...everything is mechanical...no computer control on the engine.
