After reading the "Help" section rules I know my issue qualifies

Ok, My truck is a 2003 CR SO Manual.

I had injector issues so I had them pulled by a very reputable shop and sent off to the best in the business injector fella.

Injectors were fixed and went thru in a timely manner. Injectors went back into the truck this afternoon and it just will not fire.. checked all the connections, new copper washers, all new injector internals.

Getting 15psi to the CP3, cracked lines to bleed off air, #1 kind of foams. Multiple lines were cracked open.

Everything seems to be installed correctly, any ideas?

My truck HAS TO GET ME five hundred miles tomorrow back to college.(big paper due Wed. AM. )

HELP

Max not sure what to tell you. Did you torque all the tubes properly and make sure every thing clicked when installing? if so, and your not getting any fuel to the injectors then maybe your CP3 died but that doesn't sound right. Are you sure you have your 3 connectors for the harness plugged in correctly? Are you sure you have the 2 connectors turned the right way on the MAP and RPS?

 

Mike did the install. everything torqued properly. when we crack the lines and crank it fuel does come out at a descent rate. the three connectors cant get plugged in backwards or in the wrong spot. not enough wire to do so. it is throwing no codes.

MAP and RPS are plugged in correctly.

Is it trying to fire at all with your lines cracked? I just replaced my VP on Sat. It took about 7 -10 min. of cracking lines, cranking, tightening lines, and cracking again before it fired up. However, I know you've got the CR, not sure if that type of problem/solution applies to you. I started to wonder if something else was wrong with my truck before I got it running.

 

no fire at all, not even a sputter or a buck or anything. I bet it had about three-four minutes of actually cranking time last night.

I am with all this.

 

your engine will NOT fire with the lines cracked

Tighten them up, and whirl it over, once it builds enough rail pressure it should fire.

This isn't you're grand daddy's diesel engine. HPCR systems require a LOT of pressure at the rail, in order to allow them to fire. your only plus here, is you haven't allowed it to build the pressure needed, to do the damage it can do when one of those lines is cracked. Literally, the fuel spray can cut things in half.

It takes some cranking to get them started, but like I say, leave the lines tight. When you crack them, you also induce air into the rail, and it takes even more time to bleed it out.

 

Surely Mike will get it figured out! Let us know what happens.

 

yes, we do understand this. we were just trying to eliminate variables. I do understand the dangers of the PSI made by the CP3.

..

Maybe the connector tubes did not seat properly, Mike is about to start the whole process over again.

 

Sounds like worn connector tubes was a big culprit...

going to pick up the truck now..

 

Did he put new connector tubes in it?

 

for useless information. I have experienced bad connector tubes, with small imperfections in the tips, where they seat to the injector.

Very carefully, I have been able to buff the ends of the tubes with a fine scotchbrite pad, to remove the imperfections. It takes time, although not a lot, and you can generally re use the bad tubes.

This will work in a pinch.

 

no.

That is what Mike did. My injectors came in and out four times about three weeks ago and this put a lot of wear on the tubes... so they all got cleaned up and the truck is running. and I am about to drive home with it ( 480 miles)


the truck could not have come together any later, I am getting loaded up and will leave about 2 AM, to make it to NM for class at 9 AM... what a mess.

RUN FORREST, RUN!!!!!!!

Glad to hear you got it running.

 

Wow Max! What a mess. I hope you made it back to school ok with no sleep. Glad to hear you got the truck running again though.

Max was blessed with both a "lightning-fast" turnaround for Flux tips/rebuilt bodies and an extra day of vacation to boot...

usually no reason to R&R connector tubes and increase the risk of fuel system contamination, especially when the customer is enroute to pick up the truck during an expedited after-hours installation.

However, next day I realized the tubes could be jacked up from multiple injector swaps in NM last month... sure enough upon inspection, so we refinished the ends - problem solved.

Hopefully the Smarty SW I loaded with 125mph speed limiter was enough for Max to show up in class on time!
