This smoke is a sign that the coolant is leaking into the cylinders, that means head gasketfailed or head or block is cracked.

    Its fuel not coolant

    Diesel engine then, check the compression could still be a liner that is bad.

SOURCE: '95 Honda Civic EX will not start after cleaning fuel injectors

I would talk to who cleaned the injectors, I don't know if it something they did or not. It could be a stuck open injector. The exhaust would have a raw fuel odor if it was. What it sounds like is a blown headgasket, which can just happen. The exhaust would have a sweet smell to it. Usually starts as a small leak (between cyl. 2 & 3), the engine burns the coolant while driving which you don't see. Then the coolant level gradually drops to a point where the car overheats, which warps the head, causing a large leak. Now you see the coolant burning (white smoke).
Good luck Honda Al

SOURCE: 97 grand prix gtp starts then immediatly dies

If you have a GTP these engines use a hi output fuel pump. they use a fuel pump resistor located under the battery tray (look up from under the car) This resistor lowers the voltage to the fuel fump when not in boost mode. because of its locatoin it is prone to corrosion. if you bypass the wires and the engine starts and stays running replace the resistor

Are you sure you have correct timing? its definetly a fule problem, if timing is good then turn your key to the on position and try to listin for the fule pump to prime. While the key is in on position go to fuel rail, there is a valve on fule rail called sharader valve. Get a small screw driver and press valve in to check if car has fule pressure. if pressure is present then it is incorrect timing or possible bad cam sensor.

SOURCE: 1997 Dodge Intrepid cranks over won't fire

I have this same NO START problem...
Began with tach giving readings not exceding 1200 rpm with strange 4000 + spikes.. Cruse control would not turn on or off at times and indicator light would only work sometimes..Had several episodes of excessive cranking to get it to start.. Stalling out while driving and even at freeway speeds.. Pulling the negative cable for 10 min. allowed it to start although with lots of cranking and put it in limp mode which required another computer reset to get out of.. Had thrown error codes related to cam and crank sensors which were replaced along with coil and manifold temp sensors.. Had the 9 volt power to sensors when key was on but the check engine light does not stay on with all the other idiot lights..
I wish people who respond would read the post first..
Original post states,
Cranks,No spark,No fuel pump run, changed some sensors ect...
If it cranks it ain't the neutral safety switch, starter or battery!! WAKE UP!!
Seems the computer is not turning on the coil, injectors or fuel pump for a reason.. Find that reason and you will find the solution to the problem.. Seeing as that the computers logic states are a dealer secrete the poster as I have changed many parts in blind hope that it will fix the problem.. Relays, sensors and ecu computer.. Did a visual check of all harness potential wear spots like where it crosses over the power rack..
Could it be in the wiring harness inside the dash??
Could it be a bad ground??
Can an alternator that has failed cause the computer not to start??
Can a bad oil pressure sensor cause the computer not to start??
Can signal loss from the TCU or BCU to the ECU cause this??
Is there an undocumented kill if the ECU thinks it was in an accident??
I can ground the relay line from the ECU and the fuel pump runs and pressures up and the other relays turn on as well..
This crank but no start problem seems to be common with a lot of 1994-2001 Dodge and Chrysler owners.. All these systems have become interlaced with undocumented safety features that baffle the DIYer..If you have seen this and have fixed it PLEASE RESPOND!!!!

My Toyota Hiace bus 5L engine is hard start. it crank when starting when Push Start it start. lect ctns okay new glob plug installed but yet cannot start. pls identify andadvise the problem?

I believe you earlier posted a question about a smoky engine.

Burning oil produces a very distinctive blue-grey smoke often accompanied by a sort of burned eggs smell in advanced cases.

White smoke is either steam from an internal coolant leak or can be unburned fuel in some cases.

Dark grey - black smoke is invariably partly burned fuel. Engines produce black smoke when either there is a small excess of fuel entering the cylinders or the fuel is being delivered in a form that makes it impossible to burn completely - Poor injector spray patterns, for instance.

Lots of people reckon bad injectors have no effect on starting but in my experience they have a lot of effect. Push starting produces a higher piston speed that tends to overcome problems like bad injectors or low compression from worn valves, pistons, rings, bores, etc.

I suggest you remove the injectors for testing/overhaul and ensure the battery and starter are in absolutely top condition for a good cranking speed, also ensure the new glow plugs are receiving current and the relay is working OK.

Cranks over but will not fire

Really need more info...However there are many components that could cause the problem..I would start with check all fuses/relays.If all show to be operable mainly fuel pump relay I would carefully and safely (with safety glasses) remove fuel line from front of fuel filter (directed toward front of vehicle)stand back and have an assistant crank engine over for 5 seconds while you observe filter to verify that fuel is coming out of filter meaning fuel pump is working correctly..USE EXTREME SAFTEY..NO SMOKING..,FUEL WILL NOT BE BUT AROUND 50psi IN WHICH CASE NOT THAT HIGH OF RATE..If all seems proper re-assemble to spec and check crank sensor,cam sensor..etc...Send more info and I can better serve you..

After starting car it sputters and white smoke from exhast. I drive the car for 5 min, sputtering the whole time, and turn it off - will not start until it is cranked and gas pressed for couple min. Then...

White smoke is usually from water and water will make the car splutter. Did you get water in your tank at some time. If you have water in your fuel, you will have to drain the tank and refill with good fuel. The engine will run fine once it is hot but if a lot of water goes into a hot cylinder it can cause a lot of damage.

Replaced cyl head assy, now engine won't start

Fuel pump won't run unless it starts, it is designed to run for two seconds then shut off, if it were to run and you had a damaged line you would cause a fire. The cam shaft sensor gives you spark and injector firing but the crank sensor has to work two, check to see if you pinched off the wires on the crank sensor, also does it have a coil pack? If it does leave me a post.

1999 Firebird cranking problem

well first the white smoke indicateds water in fuel system. if you have a strong fuel smell that would indicated that your getting way too much fuel. there are several reasons for this. it could be that the fuel pressure regulater is malfunctiong. the throttle position sensor is bad. it could also be a timing issue.
