To the original poster: it would be nice to have a title that is a little more descriptive. It will give you a lot of more focused answers quicker. That being said there are lots of 3.2 no-start threads here. Do a search and you will be surprised. They mostly fall into one of two categories. 1) "I had the same and it was that...." and 2) a more systematic approach:

The 3.2 engine is controlled by a DME. The two items that are notorious to fail are the DME relay (aka fuel pump relay) and the sensors that tell the DME the flywheel speed and position. Either can fail intermittently and either will cripple the car. The systematic approach is to check for power to the DME (ICV on top of engine vibrates with ignition ON. If not an alarm system or a bad ignition switch could be the issue. Next, the DME relay can temporarily be replaced by a jumper. Some suggest to carry a spare. If either makes the car run you found your issue. Next, it's down to some more diagnostics. The engine needs fuel and spark to run. There are three cases:

1. No fuel
2. No spark
3. No fuel AND no spark

Case 1
Spray starter fluid into the intake. If that makes it catch it's missing fuel (fuel pump, fuel filter, fuel pressure, or worst-case the DME or one of the injectors). It also tells you the FW sensors are good.

Case 2
Checking for spark is done easiest with a timing light or a spare spark plug. If spark is absent now it's either case 2 or case 3. To find out which you need a NOID light (eBay is your friend) or an LED test light and check for fuel signals on the injectors. If you confirm fuel signals are present but only spark is missing this points towards the ignition coil, the distributor or the DME itself. This is a classic failure mode of the DME.

Case 3
If spark and fuel are missing this points towards one of the FW sensors. If one of them is bad both fuel and spark pulses will be missing. The sensors can be ohmed out for a quick check but even if they check out O.K. that way they can still be the culprit. Lot's of cases here. If the sensors are good it could be the DME (sometimes the decoder for the flywheel sensors fails).

The other sensors would cause poor running but not be responsible for a complete non-start. So table that for the time being.
