Engine Performance problem
1989 Chevy S-10 4 cyl Two Wheel Drive Manual 280, 00 miles
My '89 chevy S10 is having trouble starting in the morning, and after sitting for a extended period of time. I have replaced the Fuel Pump and Fuel Filter. I was advised by a friend that the problem was more than likely the Fuel Pressure Regulator Diaphragm. I have bought a new one but am not sure where it is located on my truck.
