Just began having starting trouble...

Check the ignition switch in the start position and see if you still have 12 volts.

Clutch packs. time for overhaul

It is if, it is locking out your overdrive. Check to see if it shifts into all the gears your transmission has... ie. 5 speed = 4 shifts.

GOT SAME PROBLEM CHEVY DAURMAX DEISEL HD 2500 CHANGE FUEL FILTER AND OIL &OIL FILTER . WHEN YOU COME TO A STOP SIGN OR RED LIGHT IT HAPPENS .I PUT IT IN NEUTRAL AND PUMP ON GAS SO RPM'S STAY AT 1800 RPM'S

check your timing chain its probably broken. diesels have no spark plugs and uses compression ignition and uses a lot of battery charge to turn it over. thats why it sounded like it was dead. if the chain brakes the upper and lower cam and crank shafts aren't in time together so you get no compression ignition. sorry for your troubles and hope i helped

Have you checked the computer for trouble codes yet ?

fuel injection pump is failin or has issues--getta haynes manual for pro car maintenance

if i remember right its under the hood on the left side. should be a big black box mounted on the firewall. let me know if thats it.

The O/2 senser will not make it qit but the fuel pump and the ingition module will. does it start right back up? Fuel pumps heat up and quit sometimes opened the relay and it cools and or is cycled as you try to restart and it reclosesand you drive on. an amp test on the pump draw or even a scope test of the pump may isolate it as the bad boy. Pumps build up pressure and heat if the fuel filter is partly clogged. Change the filter as preventale maintanance and try to blow though the old one if it blows though hard it may be too late for the pump and you may have to change it too as the stuff that went thohg the pump that stopped up the filter. You only can heat the pump so much before its bad if you find it is change the relay also and check the ground wire where it connectes to the frame. The hanger unit that the pump is in fails too and it has to be changed on most models as you can't buy the pump any other way because it fails as often as the pump or is damaged as the pump fails. The ingtion ciol can fail, but not likly to start right back up you gota wait. The ECM cando it too but is not a common problem. Their may be engine control codes in the computer to help you determine the problem

The reason is they are pressed in and you have to press them out with a tool and some have a C clip that has to be removed you can go to schucks or autozone to rent the tool to press out and it has to be pressed back in.
