1999 Mazda B400 Picup hard to start in Cold weather

Its hard to start only in cold werather. But if I turn the ignition switch to on for a few seconds before starting, it will start. If it doesn't the first time, I can do the same thing -turn the ignition switch to on again for a few seconds and usually it will start. But if I just try starting without leaving the ignition switch to on - it will not start. This has happened the last two winters - Only when the temperature gets to about 30 deg and lower.

SOURCE: 93 Grand Cherokee 4.0 trouble starting in cold weather

Welcome to the forum. Your question has to many variables. Cold weather out here in Cen Cal this time of year is mid 40s. Is the problem when the vehicle is cold as in ovrernight but starts ok when it is warm? Does it crank OK but seem like it's not getting fuel? If you hold the throttle slightly open, does it start OK?

SOURCE: 1999 F250 SD 7.3L cold starting problem

Yes, my 2003 did the same with about 75k miles on it, stranded me on days it stayed under 40F unless I plugged in the block heater the night before, then it started like a champ. Dealer replaced the relay and a control unit under ESP warranty. There's no way to fix this one without throwing parts at it.

SOURCE: 2000 SL-1 fast idle problem during cold weather only

You need to check and/or replace the thermostat and/or the temp. sensor. Take a meat thermometer and stick it in the overflow tank. The temp gauge on the dash should register above the 1/4 mark after at least 15 minutes of driving. If so, the meat thermometer should read above 180 degrees. If the meat thermometer reads 180 but the gauge isn't above 1/4, then you need to replace the sensor. If the meat thermometer doesn't read 180 or higher, then you need to replace the thermostat. The thermostat in these cars, though it doesn't fail on its own, has an unnecessary rubber gasket that fails, and allows coolant to leak past even when shut, causing the engine to not warm up thoroughly. IF the engine doesn't warm up, the idle won't come down--speaking from personal experience. I had to replace both items on my car. Now it idles fine, and after a bit of driving the gauge registers between 1/4 and 1/2, but always above 1/4. DO NOT tamper with idle adjustments unless you have exhausted all other possibilities. They are factory set, critical, and almost never need readjusting. Good luck.

SOURCE: 1999 Chevy S10 cranks but wont start

A very common problem on the 99 S10 is a leaky fuel pressure regulator in the intake plenum.What happens is when the truck sits for a few hours or more the regulator leaks all of the fuel in the fuel injection system into the intake air plenum. This does 2 things, 1 it has no fuel pressure when starting and 2 it floods the air intake with raw fuel. Sometimes if you turn the key on wait 3 seconds then turn key off then turn key back on and just turn key to crank starter for a split second and wait 3 seconds.do this 3 times to repressurize fuel system then crank to start(you will hear fuel pump buzz each time you do this.also you may have leaky fuel injectors. Try to crank engine with the gas pedel to the floor. This will tell the computer to stop spraying fuel trhough the injectors and it will start. Joe ASE Master Tech

2002 envoy, have to turn ignition key on and off 3 or 4 times before it will engage starter


The remote and key are two different things. When turning the key, you are searching for a good contact in the ignition switch. Cold weather just makes it worse to get a contact. Replace the ignition switch. The remote start. If it is after market. Take it out. Repair the wires. Soon it will die and won't let you start your vehicle. Then you will pay someone like me, that works at a shop, to tear it out and charge you $200 to do it. I just did one. A two minute fix, because I know. and a $200 bill. I got paid $1.5 to do it.

Hi, I have a Nissan Altima 95. Had a starter problem. I live in colder climate region of Alberta, canada. I purchased a used starter from a parts seller in Texas. I replaced the starter in July of 2009....


Yes continious cranking of an engine puts a big strain on a starter in any weather, but almost certainly in cold, it takes a lot of amps to turn an engine, It maybe the fuel is starting to freeze?, Maybe it's an electrical issue such as points, plugs timing, distributor cap, rotor arm inside the cap, maybe it's just settings

Truck refuses to start during cold weather


Hi!
I presume via your very brief description the vehicle is Diesel? if so have your Glow/heater plugs tested if good? timer relay for them.
When you turn on the ignition does the yellow/amber glow plug light up for a few seconds? if so try turning the ignition on wait for it to go out turn off then back on straight away wait again turn off then back on straight away when it goes out for the 3rd time try starting you may have a couple of plugs still warming so a boost may get you going.
Good luck!

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.
