Question about 1999 Ford Crown Victoria
When I start the car, it turns over fine, but lately it has not been starting up very easily. Sometimes it will start right up, but other times it takes up to 8 tries. It seems like the problem is become more frequent in the last few days. What do ya think?

SOURCE: wont stay running after starting
That sounds like your Idle Air Control valve has gone out.
You can get one at any parts store, and swap it out in a few minutes.
If that doesn't fix the problem, look at your Mass Air Flow meter, that could be out too.

Sounds like you're on the right track. A bad TPS and ISC motor sensor
will cause the problems you're experiencing. Your ECM relies on the
readings it gets from the TPS to be sure there is enough air getting to
the engine. If the ECM gets a bad reading and thinks not enough air is
getting to the engine, it will cut the fuel supply, hence causing your
engine to die. Your ISC relies on the reading from the TPS as well.
It detects from the ECM if the throttle plate is closed or not. If
it thinks the throttle plate is fully closed, it will start allowing
air to enter the engine and bypass the throttle plate. If your ECM
starts seeing some unmeasured air coming from ISC and detects the
throttle plate is open (which it may not be due to a bad TPS reading),
the ECM will again cut the fuel supply to avoid the risk of detonation.
So, replace your TPS first and see if that cures your problem. Also, check the resistence readings of your ISC to be sure that is within spec. If your problem still occurs, check your Intake Air Temperature (IAT) sensor in your air filter housing. Be sure your spark plugs, plug wires, and distributor are all in good shape as well. Replace your fuel filter if you haven't done so in the past 2-3 years.

You can not tighten the belt, it is held on by the Belt tensioner...it's located a little to the left side of the waterpump...now it maybe getting weak, or your belt may need to be replaced...Sometimes they look good, with no cracks, but they get worn and streched out over time..or it may look shiny..either one of those will cause it too squeak..

Check the fuel pump reset switch again, if it is popped back out then replace that little switch in the trunk, any ford one will do. it works off a magnet and a bearing to close the circuit for the fuel pump. easy fix.
