My 93 dodge has always started but one weekend I went to start it and it just cranked that’s it. I changed out the distributor pickup, the rotor and cap. That wasn’t the problem. I checked the ignition coil which was good but I found out the wire going to it is only getting 5 volts. I have no idea what could be the problem and wondered if anyone had any advice. It has the 5.2L 318 EFI.

 

What's battery voltage?

 

Any codes? Do you hear the fuel pump prime? Are you getting spark?

 

The battery voltage is at 12.6 and the fuel pump does prime. I do get a very very weak spark not enough to start the truck though. The engine flashes so many codes because of the old owner but I’ve had it running properly for over a year now.

 

Reset the PCM, clear all the codes. Start fresh...... See if anything interesting pops up.

 

Cap and rotor need changed occasionally anyway. Id be looking at plugs and wires next. Also could be the crank sensor.

 

I’ve changed cap rotor and pickup coil but I was wondering where the cam position sensor is located

 

That's the pickup coil. Same part, just, multiple names.
