Engine/Transmission (1998.5 - 2002) No start problem

[TCampa]

I recently tried to jump start another truck when my truck died and now it cranks but won't start. I checked all the fuses and all in good condition please help.

Your question really should be in one of the truck specific forums where you'll be more likely to get a response. What year truck do you have and I'll move it to the proper forum?

 

[TCampa]

the truck is a 2001 3500.

Do you have a check engine light lit up on your dash?

 

[TCampa]

No check engine light, and both batteries have been disconnected since truck stopped running so no way to check codes.

First thing I would do is check to see you are getting fuel on the low pressure and high pressure sides of the injection pump. Do you have a fuel pressure gauge on your truck? If so, is it showing pressure and how much? If not you should have a schraeder valve at the injection pump on the fuel line that runs from the fuel filter to the injection pump. Take the core out of that valve (same as a tire core tool) and turn your ignition on until you "bump" the starter (just let it crank for 1/2 a second) and leave the ignition on - fuel should be spewing out that valve. If it isn't then your lift pump is dead. If it is turn the ignition off and put the valve core back in. Now loosen one of the injector lines at the head and have someone crank the truck while you are watching at the head. Don't be near that line when you are cranking because it's VERY high pressure. See if your getting fuel there. Get back to us with this info.

Yes, There is fuel both top and bottom. Thanks please continue to advice.

If your getting fuel at the injectors then the injection pump is working. You might try cracking several of the injector (3) lines one at a time until you are sure your seeing fuel from them. Then try cranking for a bit and see if it starts. That would mean that the high pressure side of the pump lost prime. Outside of that it would mean your injection pump is injecting fuel at the wrong time. If the circuit board was fried you wouldn't be getting fuel at the injectors at all.

I just had a friend that had this same problem - his truck ran for 10 seconds and stopped. His ended up being a leaky o-ring at his fuel pressure gauge which was letting in air. He replaced the gauge and it fired right up. So you might check for air leaks on any fuel lines you've added, look for cracked fuel lines or leaking fuel anywhere. One other thing you might check is the module on top of the fuel tank. Mine was metal where the lines connected and corroded away a couple years ago (98 so about the same time frame since new as yours is now) and I had to replace it.

Unless someone else comes up with something I think your about at the end of home troubleshooting.

Thanks for the info but this engine was working fine up until we tried jumping(Boosting) another truck with dead batteries. The engine died during that time. Would there be a possibility that the alternator or the PCM has been affected by the sharp current draw? Please advise.
