Question about Chevrolet Cars & Trucks
By plugging it in I assume you mean the block heater for the engine.
I would plug it in for an hour or two before starting. also give the glow plugs plenty of time to heat up before starting. If you don,t have a garage to put it in try to find a place out of the wind and with direct sun in the day this may help some. laying an old blanket or quilt or even a tarp over the hood and front end could help some. after sitting for a prolonged period of time in cold weather hook a charger up to the battery before starting to top off the battery's charge. Hope this helps.

Have the cold start valve replaced, it enriches the fuel mix during cold start and check the glow plugs and see if any are bad, to test remove the wires and put test meter to ohms and one by one test each glow plug with one probe to ground and one on the tip of the glow plug see it it goes close to zero if it does not move then that glow plug is bad, replace all that you find bad.

Fuel Cut Solenoid: Testing and Inspection
An inoperative shutdown solenoid can cause a no-start condition. Disconnect solenoid harness connector and with ignition switch in the "ON"
position momentarily touch solenoid harness connector to solenoid connector. If a "click" sound is heard, the solenoid circuit is operating
properly. If "click" is not heard, the system should be diagnosed as follows:
1. With test lamp connected to ground and the ignition switch in the "ON" position, backprobe the shutdown harness connector. If the test lamp
does not light check for open circuit form the ignition switch to the solenoid.
2. If the test lamp lights, check the ground circuit between solenoid stud and injection pump cover to see if connectors are clean and tight. If the
connections are not clean and tight repair and retest.
3. If the ground circuit is "OK", remove the injection pump cover. Connect a jumper wire between solenoid ground connector and ground. With
the ignition switch in the "ON" position, momentarily touch shutdown solenoid harness connector to shutdown solenoid terminal. If solenoid
operates, check for internal injection pump problem.
4. If the solenoid will not operate, replace the shutdown solenoid.

REMOVE OR DISCONNECT:
1. Remove pump cover.
2. Terminal contact nuts.
INSTALL OR CONNECT:
1. Solenoid in the pump cover.
- On the shutdown solenoid, make sure that the linkage is free.
- On the cold advance solenoid, make sure that the plunger is centered so that it will contact the check ball in the fitting.
2. Insulating washers on the terminal studs.
3. Terminal nuts and tighten to 1 Nm (9 in lbs).
4. Pump cover.
5. Inspect solenoid operation prior to installing the pump cover. Use a 12 volt DC power source.

There is a oil drain return from the turbo charger to the sump. If the sump oil level covers the outlet into the sump, oil will build excess pressure tin the turbo causing the sealing rings to leak oil in to the intake manifold. This would cause smokey exhaust and loss of oil. Try this. Drain the sump completely, refill with the exact quantity of oil to Mazda spec. Dip the oil and if the new oil level is lower than the full mark on the dipstick, you have found the cause of the problem. Mark this new level with a scriber or file and fill only to this new level. Hope this is the solution.
