erratic EOP then no start
Starts up and runs fine, after running at highway speeds, slowdown at off ramp dies(wont idle or restart) ICP shows about 380 PSI. crank on it forever then will restart and run fine.....In the shop shows no EOP on manual gauge when cranking until it starts(even when it does fire up normally). Hot idle has about 10-11 EOP. At around 2000 RPM EOP goes wildly between 38 - 45 PSI.(icp is normal) if I let it run for a 2-3 min in that range, shut it off and then try to restart= no start and icp around 380. Also, if I run it for 2-3 min at 2000 and then let it idle ( it will idle fine) then perform KOER test it will always fail because of low ICP. Last week replaced the low pres pump(and changed the oil) which all the problems went away. now its back with the the same problem. Also has new HPOP/IPR/oil cooler...... What is up with this thing???
