Glow plugs might be on when starter is not engaged. wont cold start. have new g plugs no fuel leaks


That is a self priming system on the 6.0 diesel. It has an electric fuel pump check to see if you have fuel getting to the filter up on top of the engine. If you crank the engine and immediately loosen the upper filter housing or crank the engine over with the cap loose it should spray fuel. If you have fuel spray up on top than you most likely have a computer or injector problem. I did have a 6.0 once that would not start because of a shorted out fuel injector. Also check your engine oil level the injectors in that engine are operated by oil pressure. No oil no start.

DO NOT USE STARTING FLUID of any kind on that engine or any engine with glow plugs. Severe engine damage can and will result from use of starting fluids in diesels with glow plugs or heating grids.

The only exception is if you disable the glow plugs or heating grid before using a starting fluid and even then you need to be certain that you know what you are doing

Nissan terrano 1996 td27 charging issue. Not chargeing.. warning light fuctioning on start up yet not when batt runs down.alternator seems ok.Battery is fine.How to check ic regulator? maybe


Did you hear the one about the Terrano with a charging problem?
Just fix it by replacing the thermostat!
Seriously - check your temperature gauge does it take ages for the needle to barely get off cold? (and is the heater useless?)
The needle should get to just below half way in 2 or 3 minutes.
If the thermostat is stuck open, then the engine does not get up to temperature.
The glow plug control senses the engine temperature is cold, so the glow plugs stay on for an extended period of time (sometimes 10 to 15 minutes) - short trips particularly in winter, with more headlight driving - the alternator can't keep up with the current being drawn off and from time to time you will end up with a flat battery!
A thermostat is cheap, and easy to replace (three bolts and about a half litre of coolant - I pumped the coolant from the top of the radiator, and didn't spill a drop when the thermostat housing was removed).
Sure enough, as the engine temperature reached about 50C, the glow plugs turned off.

The glow plugs on my 99powerstroke have to be cycled several times on a cold morning. I get a M.I.L and codes 1396/1397.I have put in new glow plugs and a new relay ? ? the relay is closing when key is...


the glow plg system is monitor when the glow plugs are commanded on for more than 35 seconds and when the battery voltage is between 11.5 ans 14 volts. dtc 1395 or 1396 will set on the bank that is reading less than 32 amps or the the bank that is at least 8 1/2 amps lower than the other bank. Loose fitting pins in the circuit connectors causing high resistance or high resistance glow plugs on the circuit could be the cause. A shorted circuit or low-resistance glow plug(s) on the oppisite bank could be the cause. Each bank needs to draw more than 32 amps but not more than 8 1/2 amps apart. Obviuosly your glow plugs are not the problem since you replaced them all. Therefore, in my past experiences I have found the gaskets and/or the injector harness (under the valve covers) to be the culprits. A simple test you can conduct with an amp meter will help determine if you have a glow plug system that is under performing. First let the vehicle sit for at least an eight hour period. Pop the hood and find the Black/Orange wire going from the solenoid to the glow plug relay. place your amp probe around this wire and turn the key to the on position (do not start the engine). You should have an amperage draw at around 200 amp and it will start to drop as the glow plugs warm up. Now if your initial reading is not close to 200 amps, then you have under performing glow plugs. At this point you will have to ohm out each valve cover gasket and each individual injector harness to determine which one is open. At that point replace the defective culprit and clear your Dtc's then recheck.

Hope this helps,

Ron.

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
