No-Start / Hard-Start Problem 700 1989

posted by  someone claiming to be stavros on  Tue Sep 10 03:43 CST 2002 [RELATED]

LH 2.2 or 2.4? If you run fault codes, then you've got 2.4

Try the items mentioned in the FAQ as common no-start issues on Bosch 2.4:

-rpm sensor
-radio suppression relay
-solder cracks in fuel injection relay

As for the FPR vacuum line, the FPR meters relative fuel pressure, not absolute. The pressure is metered according to the difference between fuel pump pressure and manifold absolute pressure; the vacuum line supplies the MAP signal. An internal spring controls the difference.
