What is the PCM????

[SHO SPD]

I am just curious what the PCM is? And would The MAP manifold absolute pressure sensor or the EGR valve cause a sho to not fire-start.

PCM = Power Control Module.

I would think a map sensor may cause a no start. But I know very little about the V6 SHO's.

Good Luck

i would try the DIS.... when you are under the hood.... at the left of the intakemanifold... there is this gray thing with plugs on both sides... think it actually says like FORD DIS or something... that might be bad.... GL dude!

PCM -- basically the computer.

The acronym PCM is commonly used to refer to the engine computer, or Electronic Engine Control Module. However this is not quite a correct reference. The acronym is for Powertrain Control Module and from about 1990 until about 1992 Ford used it to refer to the Module as PCM only if it controlled both engine and transaxel. Beginning in 1993 , PCM means all engine control modules.

Very briefly, and simply, the PCM maintains a fuel air ratio of 14.1 to 1 using the information supplied by the various sensors. While it does much more than that, the bottom line is to provide fuel economy and minimize pollution. rangerj

There is no MAP sensor on the SHO. There is, however, a BARO sensor.

I doubt that an EGR issue would cause a no-start. It would be a rarity in any case.

What kind of trouble are you having? Have you tried to pull codes?
