Well been away awhile trying to make some moola in this horrible season I'm having. Now my truck died. Heres what happened. Leaving walmart in parking lot driving slow of course. Suddenly just stops running. Died so smooth I didn't realize it immediately. Dead on side of lot. Still cranks over but does not start. I have stock oil gauge and a mechanical one. Notice when cranking I have no oil pressure. Check oil, full. Change CPS just in case. Tow home. Have infinity dash daq so try to run codes. It keeps saying can't communicate turn on key, which it is on. Try several times will not link. Try to load new program. Cannot connect still. Get my lap top and plug in AE. Finds usb port but cannot connect. So can't get codes if any, no connection for some reason. Notice that when trying key on and off my glow plug light no longer goes out, just stays on. At home now battery charger on, start cranking to get some oil pressure. Dash gauge reads normal after a few seconds, mechanical gauge reads nothing then creeps up to about 10psi max. So appear to have oil pressure problem. Pull plug on top of hpop put rubber hose on and crank. Oil flows out but not blast out. THen notice mechanical fuel pressure gauge on the prv under the hood reads 0 as well. Turn key on, climb under, fuel pump not working. Unplug, check with tester, no power in wires or plug near pump. Hot wire pump, pump works and pressure gauge goes to normal 65psi. So pump works. Still no start. So I'm stumped. First off, I seem to have lost low pressure oil, but have some pressure. But one gauge says ok, other not ok. Fuel pump works but is not getting power. AE, and infinite ( which is AE) Both cannot connect to the computer. Dash daq reads no gauges except pyros which are independent on there own. So I'm thinking I may have a dead computer?? I did check as many fuses as I thought were related to it, found no dead fuses. No communication makes me think dead computer, and also because fuel pump isn't getting power either. And also cause of the odd gauge activity like the glow plug light staying on, and the dash gauge working but not the mechanical. The mechanical never used to read until the motor started unless you cranked a real long time. So I suspect I have pressure. Although when it did read it read low. I'm out of ideas. Any suggestions?
