Last week her trooper just died,wouldn't startt.We changed the fuel pump it ran for a week again it won't start.
Did you check the fuel pressure before all of this fuel pump replacement? If the fuel filter is old enough to be clogged up, it should have been changed long before replacing a fuel pump unit. Your fuel filter should be changed every 30,000 miles. However, it would have to be TOTALLY clogged up to keep the engine from starting. It would have been causing all kinds of drivability problems LONG before that could happen.
Then, has anybody bothered to check for spark when the engine will not start? Has anyone scanned the onboard computer? (which happens to be in full control of both the fuel system and the ignition system)
You just might be trying to repair the wrong system...
There is no way anyone online can accurately tell you why it will not run without checking the vehicle first....although many uneducated DIYers might GUESS for you...which seems to be just as good as you are already doing....
PROPER DIAGNOSIS REQUIRED!
