Default 2001 dodge 1500 5.2

Ok so I’ve went trough and changed my distributor cap, rotor button, pickup, coil, crank shaft sensor, and I am still getting a crank no start on my truck. I am not sure what else to check or change this is starting to get really expensive. I am getting spark from coil. I took wire off distributor cap and checked for spark. I am getting spark there. But it seems I lose it through my plug wires when cranking I put a multimeter on end of spark plug wire and the most I’ve gotten is a reading of 2 volts? Any suggestions would really help

Our trucks don't like parts store sensors. That may be your problem. Have you checked fuel pressure?

Do you have a scanner that you can plug into the OBD2 port? If so, any pending or stored codes?

You cant test that amount of voltage with a multi meter, It's in the thousands of volts and could fry you meter. You might want to explain when this issue started.

I went through the same thing with my 2001 5.2 at 182,000 miles. Finally replaced the PCM and problems solved. You can pick up "spark" but if it isn't at the right intensity at the right time it is a no go.
After that frustrating experience I ordered a second pcm from Flashmasters, and plugged it in to verify all good. I regularly set out on very long trips and have had no problems since but carry the extra good PCM, crank sensor, coil, etc....and a basic tool box!

I carry a spare PCM myself just in case. I also had an issue with my aftermarket Borg Warner crank sensor failing prematurely and leaving me stranded on the side of the road. Luckily, when my truck died on the road, I had my scanner and it provided a pending code about the crank sensor failing. I replaced the crank sensor with a MOPAR crank sensor I was able to obtain online via a dealer (much, much cheaper than going to a local dealer) and it solved my issue. If you don't have a OBD2 scanner, you can grab one at Walmart for $20. If you have a code in the PCM, it can help to narrow down your issue.

As one stated above have you made sure fuel pump is kicking on? Or have you tested at pressure at the rail

Default No start.

What position does Your rotor stop at after cranking? I also have schematics of wiring diagrams for charging supplies and starting diagrams. Also procedures to follow through step by step ask away. Has it started ? Firing order is a good place to start. Some times when replacing your belt you can advance or shorten the timing causing delays or shutter effects.

the belt has nothing to do with timing….your distributor rotor placement and where your crank pulley is is the timing part. If you remove the distributor you must have engine at TDC, the pickup plate has a line that the rotor should line to when at TDC. Verify at TDC that the line and rotor are synced
