Is my computer to my car dead or could it possibly be a wiring problem?

Question

My 2000 Mercury Mystique GS 4 Cyl won't start. The battery turns on and it cranks like it's going to start but doesn't. When I connected the obd2 machine it said unable to establish a connection. but before I did have a check engine light but now the light doesn't even come on when I put the key in

Answer 1

Unfortunately, there are several things that could cause a no-start problem. From a national database of repairs, here is the list of the most common causes:

• Fuel Pump, Fuel Filter
• Fuel Pump
• Battery
• Timing Belt Kit, Valve Cover gasket
• Engine Timing Belt

The same goes for not the connection problem:

• PCM Fuse
• Faulty PCM
• Poor PCM connection
