Common Rail Pressure Tester Simulator
My 2003 Ram had hard start that became no start. No truck for the 3rd week while await for the injectors rebuilt. It took about two weeks to troubleshoot and agonizing over which route to take for a set of injectors. 6 injectors are high dollars regardless of whatever route. Reading on this forum and various searches came about the same conclusion. Injectors time!🙄 That is I have checked and retorqued all related bolts and nuts! My purpose of this thread is to help those newbies even experience people of what I have found out. This valuable information is of my own as I found nothing on this forum as such. Once you read the rest you will agree it is indeed.
1. I had two bolts that were loosen on 2 injectors. No where I read or saw on Utube and this forum of check or retorque to 89 inlb all injectors bolts. Loosen injectors well you can figure out what that does to the pressure!?
2. Can't find anything to check rail pressure at reasonable price on. I do not want the mechanic gauge. I do not want to deal with open the fuel line with high pressure connection. I don't like the ridiculous charge of high pressure fitting. But there is a solution and a very good and affordable solution for the diy.
The common rail has a sensor that feeds the ecm voltage signal that corresponds to actual rail pressure. Why don't we use that instead of the stupid mechanical gauge and hook up and the danger of exposing to high pressure leak?
Well people that is exactly what this is about. Rigorous search online I found it. It is called CR508 tester, simulator. Take your pick Amazon, Ali, eBay all have it. Very affordable under $40 I paid.
Now are you ready for the cool part. It can read rail pressure live. It can simulate rail pressure any amount you set it at. Metric in MPa so conversion to psi is needed.
Simulation is a terrific idea as you can set it to 5000psi. If the truck fires right up then you immediately isolate to low rail pressure then the rest is isolation for bad injectors or retorque nuts and bolts and overall general inspection for leak. It takes 5 min to hook up all is electrical NO mechanical line gauge of any kind. Now that is what I want!
I bought the tester after I got frustrated with not knowing the rail pressure and paid for a friend mechanic to hook up his $2500 Snap on just so I can get the rail pressure. By the way his $2500 Snap on can't simulate and my $40 tester can😮hah! Now I did everything else already and it wouldn't start as I tried to avoid replace the expensive injectors. No luck!
Troubleshoot the hard start no start of any common rails not just Cummins has became easier and affordable with this tool. It can do Bosh, Delphi, Denso common rails.
No this is not a commercial. This is a real diy case that found the valuable tool that would be very valuable for troubleshooting common rail issue and now I pass on freely for those that suffer from the hard start no start.
Frankly I am not impressed with Cummins reliability as claimed and their design.
1. Injectors worry at 150k miles of leaking or going bad
2. Why the hell do the feed tube and injector hole metal match connection that prone to leaking because all diesel engine vibrates like hell?
3. No code, no warning light of abnormal rail pressure instead it has a warning of burn out light bulb. Uh what good is the truck if I can't drive it because I can't start it because it has a leak somewhere due to bad design and no warning of any kind for me to know of abnormal rail pressure. Call that stupid as it is!!!
I don't have any freaking codes of abnormal rail pressure on either my plain Jane OBD scanner and so was the $2500 Snap on tool from a friend. Unbelievable!!!!!!!!!!
There now you have it. Please don't compare this with the fancy dandy pro. tool. This is for the diy practical someone likes me. I don't fix cars trucks for a living just my own truck when it breaks down.
Honestly I have no doubt even the pro. can use the tool too.
Benefit from my pain, time and effort of this information I share with you. Hell had I read this same information this would have saved me ton of time, search and read. I just go buy the tool with the money I paid someone to scan for rail pressure.
