Testimonial: "thanks .the old pompe is good but a firt my mecanic instal the new ,and the truck start on the lift.but when we put down the truck it go off."
If the truck started when on the rack and suddenly does not after lowering it; check the connector where the new pump was plugged in. It may have come loose as the vehicle was lowered. Make sure the connector clicks or locks together when assembling it.

It could be a clogged fuel filter or a bad fuel pump. Also try replacing the spark plugs and spark plug wires and having the timing checked. Good luck.

The only thing left in this system is the fuel pressure regulator. You need to check pressure before the regulator and after the regulator if there is the problem then you need to replace it. I hope this helps. Don't forget to rate my answer.

If the pump is in the gas tank,which most new vehicles are, you'll have
to drop the gas tank, to remove the pump and sender. Make sure you
do this with as little fuel in it as possible,seeing that fuel is like 8-10 lbs.
per gallon. Good luck.
