SOURCE: 2000 escalade wont start, changed

crank sensors on GM's are usually pretty easy to replace and not expensive-and are usually the reason for a no spark problem.

SOURCE: I have a cadallic escadale. It will turn over but wont start.

The fuel pressure should be 60 to 65psi in your system with the engine not running and fuel line primed, (ignition key's to the run position). Once engine is running the fuel pressure should drop by 5psi, change the fuel filter and recheck the fuel pressure at the shredder valve. it's known for the fuel pump to fail when the gas tank runs low or out of gas, the pump will end up burning it self out since the gas is what keeps the electric fuel pump cooled. The other thing to is putting gas through the top of the throttle body to start the engine on the SEFI is a NO NO, well a BIG NO NO. it's been know for the gas in the intake to catch fire and burn up the poppet valve in the injection system causing the replacement of the fuel injection system. Keep me posted and good luck, be gald to help you get your truck running again for the july 4th. OH and it was not mentioned but did the fuel filter get replaced???

I REMEMBER WORKING ON THE EARLY 80S MODEL CARS.I WOULD SCAN IT.IF YOU GET CODE 55 YOUR PCM FAULTY.IF YOU GET CODE 12 NO DISTRIBUTOR REFERENCE PULSES TO ECM OR PCM. POSSIBLE CAUSE OPEN IGNITION COIL OR BAD PICK UP COIL OR IGNITION MODULE.
