Had the dash of my 98 B2500 out to change the heater core. Got it back together and all the electrics work (turns over, lights, blower motor...) but it's not firing. Went back in and checked all the electrical connections but found nothing wrong.

Anybody have any ideas? Any help will be greatly appreciated.

Thanks

Craig

 

Not sure if your truck has it, but check the passenger side firewall to see if you have a fuel pump inertia switch. If you do, press the button to reset. See if the truck will start then.

 

Bingo, fuel pump inertia switch. I never knew such a thing existed. Thanks very much.
