Question about 1998 GMC Sierra
I have a 98 GMC C1500, 5.0L, 4L60E. It turns over fine, but won't start. Fuel pressure is 60 while the fuel system is pressing up, then drops to 56 psi when the pump shuts off. It also has good spark. I scanned the computer, and have a P1870 DTC using an autoXray EZ-Read 2000. I can't find that code in any of the repair manuals I have. Any help would be greatly appreciated.
P1870 is a transmission code. This code indicates a slippage in the trans between 1st and 2nd gear shift. This code would likely have nothing to do with your hard/no start issue.
