LONG CRANK & COOLANT PRESSURE
05 131,000 miles, had coolant puking problems. Did oil cooler, egr cooler delete, standpipes, stc kit. This helped with coolant issue but still building 13psi after running about 30 min. with no load, over 16psi with load, so I am getting ready for arp studs and head gaskets. Now had a long crank issue first time took about 2 min. off and on cranking to start, then fine for 3 weeks, did it again, then good a couple days then yesterday, no start tried for 10 min. to batteries died, had to be towed. When I got home, charged the batteries, truck fired up. Could this be fuel pump issue? pump sounds a little speratic when ignition on. Last but not least exhaust smell in cab and noticed soot only around exhaust manifolds to block. Will gaskets typically solve this problem? and will an exhaust leak like this cause significant power loss? this site has been a life saver and thanks for all the help!!
