replaced ignition coil pack, PCM and spark plugs. No signal comes from the computer to fire plugs 2 and 3, but 1 and 4 are firing nicely. The van WILL NOT start, but -- at times -- it tries.

Why does 98 regal shut off when turn signal light is activated?
This is due to a bad PCM which needs to be replaced. This is a common problem in these cars. I believe its due the PCM being located in the steering wheel column and just over the years wearing out and breaking due to it vulnerability. Unfortunately a new PCM for a Regal will run you $400 plus. But it's a safety matter and should get fixed. What's happening is a faulty control switch in the PCM that believes you are shutting the ignition off when you are making a turn.
99 jeep grand Cherokee - will a faulty PCM cause the cooling fan and cruise control and horn to stop working?
