There are 2 possible root causes:1- Your cold start valve is bad. 2- Your cold start valve is good but it can't open since the coolant temperature is bad not reporting low temperature to the ECM so it didn't give an electric voltage to the valve to open during the start. Hop this can help.

When i turn the key the engine cranks over but does not start, if i continue to crank it for a minute or two then it will eventually start and drive just fine. any ideas?


This sounds like a fuel system priming issue. When you first turn the key to the ON position (not cranking yet), you should hear a three-to-five second buzzing noise. This is the fuel pump running to pressurize the fuel system for cranking. This is controlled by the PCM and is relay activated. Once the vehicle starts and oil pressure rises, then the fuel pump is activated by the PCM via a different relay. If you can't start at first, what is probably happening is that the prime is not occurring and you have to crank it until the PCM sees oil pressure and then fires off the fuel pump. It could be PCM wiring or a bad fuel pump prime relay.

1999 blazer only starts when primed and then wont start after sitting


Black smoke is usually extra fuel, but you say you are priming it to start so that could be why.
Have you checked fuel pump pressure before and after cranking ?

Silverado won't start without starting fluid


Check your fuel pressure it should be 60-66 psi with the key on and engine off.Sound like you might have a weak fuel pump.

Yes this sounds like a problem with the check valve in the fuel pump. it is letting the fuel drain back out of lines so system has to prime itself before fuel reaches engine. try and cycle key a couple times when it acts up this will cycle pump if it cranks rt up after you do this it is the pump.

Hello. If you remove the fuel filters and fill them with fuel, then hold the accelerator pedal to the floor while cranking the engine it should start. If that does not work, spray a little starting fluid (ether) into the air intake while cranking, just use the ether sparingly. This should get you going again, good luck.

Is the pressure in the fuel system not holding? Fuel pump may be failing or the filter may be bad. Sounds like you're pumping the fuel system back up to pressure before the truck will start. Like when a fuel-injected car runs outta gas and you have to prime the system before it'll start again.

04 f250 6l diesel cranks but will not start when cold.


it seems that because it sit's for a while that perhaps it's losing it's prime. if ythis happens generally you will have to reprime the fuel system. in a diesel system you also have glow plugs to help ignite the fuel. check to make sure your glow plugs work, but i would start with whether you have proper prime in the fuel system.. please rate this
