I have a 1999 Mitsubishi fuso fe that is having ip problems. It has a zexel tics pump on a 3.9L Mitsubishi. It's very hard to find any info on these pumps and from what I've found out it cost more to have them worked on than what my truck is worth. I'm pretty good at repairs but being it's all electronic I'm at my end. Wondering if anyone has knowledge of this system? Or even if I can change it out of a older mechanical IP? Thanks.
