What to do when your diesel engine wont start?

Put your head close to the fuel tank and have an assistant turn the key on without cranking the engine. You should hear the fuel pump in the tank come on. Tap the top of the fuel tank lightly with a piece of wood or rubber mallet and see if the pump unsticks. This will sometimes be enough to get the truck running until you drive to a garage.

Why does my Ford F250 diesel not start?

They could not be functioning. The diesel engine doesn’t have spark plugs like most trucks, instead, it used glow plugs, which are designed to heat up and assist in starting the diesel engine. Although the glow plugs aren’t always essential for starting, they assist the process especially when the ambient temperature is very low.

How to troubleshoot a 6.2 L diesel engine?

Diesel engines have very high compression ratios and require a large amount of electrical energy to crank. Check the glow plugs. Most 6.2 L diesels came with one relay but early models had two. Test the glow plugs by unplugging the electrical connection from a glow plug. Hook up an ohmmeter to the glow plug terminal and ground the other end.

What kind of fuel system does a 6.5 L diesel have?

The fuel system on this engine includes the fuel tank, mechanical fuel pump, fuel filters, fuel line heater, injectors and fuel lines. The electrical system is less critical to this engine than on later 6.5 L diesels because the injection system is purely mechanical.

What should the crank speed be on a diesel engine?

I might move on to the compression and proper glow plug operation, but without the proper cranking speed, the engine compression is a moot point. Most diesel engines need a minimum cranking speed of 150 rpm. If the starting system is not capable of turning the engine fast enough, do some testing and find out why.

Why is my Chev 6.5 Turbo Diesel not starting?

Can a compression test be done on a no start diesel?

Proper compression is also a much needed part of the “no start” problem analysis. There is a time and a place for a mechanical compression test, but that test is way down at the bottom of my diagnostic test list. On the late model diesel engine, accessing a point to get the compression can be a time consuming task and there are easier ways.

Why does a 6.2 L diesel engine not start?

The electrical system is less critical to this engine than on later 6.5 L diesels because the injection system is purely mechanical. A troubleshoot of this engine should walk through the essential components one at a time.

Why does my car engine not want to start?

If the engine still doesn’t seem like it wants to start, probably fuel is getting into the cylinders and your problems lies somewhere else. However, if the engine runs momentarily and dies, then the problem is that fuel is not getting to the cylinders. Check for a clogged fuel filter, or a bad fuel pressure regulator.

Why is my Duramax diesel engine not working?

The trucks computer keeps track of how much fuel needs to be added or subtracted from each individual cylinder to make the engine run smoothly, and this value is called the balance rate. If one cylinder is contributing too much or not as much as the rest, the cause is usually a bad injector and the cure is a replacement.

Where is the injection pump on a 6.5L diesel?

There is a large round 15-way connector near the back of the intake manifold which joins the injection harness (which contains all the wires to the injection pump) to the main engine harness. Open this connector and ensure that the terminals are in good condition and not corroded as is common in northern trucks.

Re-attempt to start the truck. Turn the ignition on and note if the service engine soon (or check engine) light comes on. If it does, this is a good sign that the computer is receiving power and is functional. If it does not, then you must proceed to check power and ground at the computer. This is beyond the scope of this article.

What happens when the glow plugs fail on a diesel engine?

Hard starting. Unlike gasoline engines, which use a spark to ignite the fuel mixture, diesel engines rely solely on cylinder pressures to ignite the diesel fuel mixture. If the glow plugs fail, the engine will have to overcome additional pressure in order to ignite the mixture, which may result in hard starting.

What should I do if my glow plugs are bad?
