Engine Performance problem
1999 GMC Sierra V8 Two Wheel Drive Automatic 17000 miles
i have a 99 sierra with a new engine it has about 17,000 miles on it I swaped the engine myself due to a blown head gasket, before the new engine my truck would turn over than start after like 10 seconds so I changed the fuel pump solved the problem for about a month than it did the same thing when I got the new engine it stoped having the problem than 2 months later it started turning over for a while than start. What is causing this?
