I have a 2002 Caravan with 3.3l that won't start. It's getting plenty of fuel. I get the codes P0351, P0352, P0353 coil codes. I have replaced the coil pack. I can fire each coil using a scanner. The voltage going to the coil is fine while cranking but the PCM is not firing the coils. Does anyone know what could be wrong? Do these have any common problems that might cause this? Ground connections?

 

Probably the PCM is bad then, the only other thing that the PCM relys upon is the cam and crank sensors to fire the coils. But in that case there wouldn't be DTCs for the coils. No other soultion unless you have a weak power (corroded wire or something) from the ASD relay to the ignition coil.

 

my van does all of above but no dtc

im having the same problem i get no spark, new sensors ,new pcm ,new coil pack and still nothing....

 

wanted to know if you ever fix the problem and if you did it what was it

 

This is an old post. You really need to start another new post, With year and engine size. But I would start looking at the rear cylinder head for the injector wire harness. They are known to melt the wires.
