Hello, I need honest advice for my van listed above.

It was running fine and I started it one day and the check engine light was on and it was kind of putting

I originally got these codes from AutoZone: P0300 and p2302 , which o the the to repair check engine light began flash and continue to put .

We have replaced:

Spark plugs and wires
Coil pack
Cam and crank sensor

After replacing these there is no spark coming from only 1 location on the coil back and car is still having same issues. can anyone suggest what could be wrong? a mechanic told me that it could be an electrical issue. has anyone else experienced this?

Hello my name is Dave.
First thing we need to know is how it was determined that there was no spark to the one cylinder. f you are sure there is no spark at the coil pack then it has to be a faulty coil pack due to the fact that you van has what is often referred to as either a batch fire or waste fire system, what this means is that two cylinders fire together therefore if you don't have spark coming out of one the ports of the coil pack then it has to be faulty. And if you don't have spark at the plug but you do at the coil the wire is faulty, what I would recommend is to switch the wire of the non firing cylinder with another one and see if you get spark at the plug of the previously non-firing plug, if you don't have the coil pack warrantied if you do have the wires warrantied. Please keep us up to date on your progress and thank you for using 2CarPros!
