[QUOTE="Richard L, post: 1029244, member: 52972"] I agree with most of the other suggestions. Be sure you check the PVC elbow connector...a commons source of vacuum leaks. I would also be sure that the IAC and throttle body are squeaky clean. If you are not getting fuel pressure, check the fuel pump fuse, and check that the fuel safety cutoff switch has not been trigger to shut off fuel. Early model Sport Tracs were notorious for having fuel pump leaks in the tank and loosing pressure....however the only way to tell if it is the fuel pump leaking pressure or not even pumping is to check the voltage at the fuel pump when the ignition is on. The fuel pump should run for about 10-15 seconds as soon as the key is turned on to build up pressure. If you are getting voltage but the pump is not running or not building enough pressure, then you probably have a bad fuel pump. ...Rich [/QUOTE]
