92 Dodge Caravan - Voltage from coil but no spark
My wifes van quit running today. It has been acting up. Won't start for a minute then will. Today it quit at a stop sign and would not start again for anything. I put gas in the cylinders. Poured gas in the throttle body. Nothing. I then checked for spark at the spark plugs. Nothing. Tried grounding to everything. Even ran a pair of jumper cables from the battery negative terminal to the spark plug nothing. I bought a new coil, new rotor button and new spark plugs, nothing. I then got brave, touched the side of the van and the coil. Little rotating shocks. Grabbed a bolt on the side of the van and got a pretty good shock, better ground, made me let go. Then I tried the same thing from the distributor to the spark plug little shocks, big shock. Still no spark at the spark plug though. Any suggestions. Is there some reason voltage wouldn't be high enough?

More information. I tried getting the engine fault code. Turning the key off and on 3 times. No fault codes. However, the car then started when i tried it. When it starts it starts perfectly. Then it started again next time. Then it didn't start again for several times. Sometimes turning the key on and off several times will cause the car to start. Then maybe one or two times after that. Any ideas.

Follow UP.
I traced it down to a relay on the drivers side of the car. Apparently it wasn't seating good, or it is starting to go bad. Pulling up on the wiring harness at the relay allows it to start every time.

I realized I forgot the year and the type of vehicle. I had previously edited the title. It looks like it only placed the new title in small type in the top right corner of the post. It is a 2.5 liter engine, 4 cylinder. I never added that. The fault was a relay on the driver side beside the battery. I'm just posting this in case it helps anyone else now. Thanks for the reply though.
