1999 gmc sonoma highrider zr2
I have my dad's 99 GMC Sonoma high rider ZR2. It has a rebuilt motor put in rebuilt transmission, rebuilt transfer case, rebuilt front and rear gears. New electronics, new sensors new PCM and I'm trying to figure out why it turns off after an hour of driving. Everything was done in stages when the broke. Motor first then fuel pump and filters, transmission an t case. Sensors and pcm done. About to get a new radiator an distributor and flush engine og radiator an distributor. Did refresh distributor with new rotor and cap. When the truck dies it sputters than goes dead but starts right up 20 seconds later I do smell gas. Been chasing this problem for 2 years now replacing parts with new ones. Any ideas?
