Question about Mazda Cars & Trucks

1 Answer

Hard to start only in cold weather - Mazda B400 Pickup. It starts fine in warm weather. Last year all summer it started fine. But when winter came it became hard to start. Same thing this year. I found that if I turn the Key to on for a few minutes before starting it will start. If it doesen't, I turn the key on again and wait a few minutes and usually it will start the second time. But if I keep cranking it, with out turning the key to on, it will not start.

CHECK THE COLD START ENRICHMENT VALVE AND OR THE IDLE CONTROL VALVE. I AM ASSUMING THAT YOUR VEHICLE IS FUEL INJECTED. ONE OF THOSE HAVE GONE BAD.

SOURCE: B 2500 diesel pickup hard start from cold

Hey mate,

I have a Mazda B2200 from 1985, which has the same R2 diesel motor, and I had this same problem, which was exacerbated by the cold of winter....even here in a mild Melbourne.

Each time you turn the ignition on, the QSS (Quick Start System) powers up the glow plugs for about three seconds. This recycles again about three times, then.....nothing. The QSS reckons that you ought to have the bugger running by now!

In my desperation, I located the cable to the four glow plugs, and ran a second wire from the battery (+) via a push-button switch which I installed on the dash. This is my glow-plug BOOST circuit.

Now, when I want to start from c-c-c-cold, I push the button (with the ignition on) for about ten or fifteen seconds, which gives the glow plugs a goodly time to heat up the combustion chamber, and when I hit the starter, she usually fires up with a rattle, and a cloud of grey exhaust smoke.

BINGO!

(Of course, once the motor has warmed up, there is no need to use this BOOST circuit, for the combustion chambers are already hot enough to detonate the injected fuel.)

Have a go at it, as I know that it works!

John.

1992 toyota tacoma pick up will not start when it is colder outside. Usually when the temp is closer to 0 degree's. When it warms up outside there is no problem.....


Do you have a good battery? Cold weather is hard on batteries. Also you may need to change to a winter grade of oil. Oil thickens in the cold a makes starting difficult as well. Let me know. Thanks.

Should I use 10w30 or 10w40 oil


If you live in cold climate I would recommend 10w30 for winter use, it's a bit thinner and will start better. However if the truck is used hard, such as for towing loads I would use the 10w40. If you live in a warm climate I would use 10w40 all the time.
