Do not replace the lock!
replace the ignition switch
the switch activates the starter then springs back keeping the engine running but, disconnecting the starter
repair the horn short circuit after this

if it is getting fuel then there is no problem with pump relay or switch, check for spark. if no spark it is ether the crank sensor or the coil pack.

Drove our 2002 F550 Diesel...shut it off and it would not restart. The dash lights do not come on and the motor cranks fine.... just won't start. Robbie


If the dash lights don't come on then the ignition key switch is no powering the electronics and the diesel pump cutoff solenoid - there is no way for the engine to start.
You need to replace the ignition switch

For that the steering column will have to be dismantled - it's a quite complicated job and if you have never done something like that before you should leave it to a repair shop. Anyone will do, no need for a dealer's shop.

The fuel pump pressure shoud be 55-61 psi . Check for spark by removing a ignition wire at a spark plug and put a spark plug in wire and hold to engine ground and crank engine , if no spark then remove coil wire at cap and repeat.If still no spark then coil , module,,crank sensor or pickup may be the problem.
Check fuel pump pressure first and if available check for codes for possible crank sensor.

I have a 98 bravada, it will start and run for about 3 seconds then die


Check for correct fuel pressure. Connect pressure guage to schrader valve on fuel rail. Turn key to ON position without starting engine. Fuel pressure should be between 55 and 61 PSI. If it is too low, replace fuel pump in tank and fuel filter.

98 astro van starts and dies immediately. Spark OK, fuel 55 psi


does it rev up when it does start?pull out the mass air flow sensor(big nut with electrical plug in the middle,)spray the inside part(looks like an arrow head with a spring behind it)with carb cleaner and try it again,be very careful because they break really easy...does it sound normal when it starts then dies right away?then its posible the injectors arent spraying correctly due to dirty injectors or bad fuel regulator getting either/or too much fuel or not enough

underneth the intake manold is were your fuel injector poppet nozzles are, more than likely the fuel line hose that goes thru the back of the intake is split and leaking fuel underneth the intake manifold if you check the fuel pressure you will find that the fuel pressure will drop down to 0 psi as soon as the fuel pump shuts off and it should hold pressure
