The sequence of flashes represents the system diagnostic message. Count the first sequence ofpatagonia shoes3 flashes in order to determine the first digit of the flash code. After a two second pause, the second sequence of flashes will identify the second digit of the flash code.
Cat Man,the engine serial number is XXXXX check engine light came on,as far as the fuel primer it has pressure when you unscrew the primer rod and push the rod down it is very difficult to push down,as far as hearing the pressure relief pop i havent heard that,i have changed the fuel filters in the past and have had to use the primer and it took several pumps to get it pressurised but still never heard a pressure releif pop,in this case it seems to already have pressure,is possible could you call me to speed up this process,this is a flatbed tow truck and my only source of income and i could stand to lose hundreds of dollars a day,thanks ,Dave XXX XXX XXXX
Sorry. JA does not allow any other contact other than on here. Sorry.
Since you have pressure on the hand primer, I assume that the engine has enough pressure to crank. You may not here a popping on an 8YL engine.
There are only a few other things that can cause the engine not to crank and run.
First is power to the ECM. A good way to tell is the ECM is getting power is the check engine light. When you turn the key to the on position, the check engine light should come on then go off. If it does not come on, the ECM is not getting power. I would check the fuses.
Second is the engine speed timing signal. This signal comes from the 2 sensors that are located on the drivers side of the engine, behind the front cover.
Third I would be concerned with what is called the Injection Actuation Pressure Control valve. Or IAPCV. It is located on the HEUI pump and is a known problem on these engines. When these fail, it can keep the engine from starting and running. If the IAPCV has failed, the ECM normally has flash code 39 logged.
Cat Man,I did reply to you about the link you sent me not being able to load on my computer and you never replied,however I did call a Cat Dealer here in Ohio and they faxed me a photo copy that showed where the sensors were located,also you never explained to me where the IAPCV valve and HEUI pump was located,I also had a local diesel mechanic come out with a diagnostic machine but he claims that the VIN numnew patagonia houdiniber isnt coming up properly in his machine,his machine was saying that my truck is a 2005 so he was of no help either,he also said that my truck should have two diagnostic ports,one rectangular and one round but he could not locatepatagonia better sweater icelandic hoodie the round onepatagonia shoes2,so I am kind of at my wits end here and losing my patience so I went ahead and ordered the two Engine Speed Timing Sensors at 123.00 a pop and will install them sometime Monday and if that takes care of the problem you will be paid for your time,I have used this site once before for a problem I was having with my 99 Ford Explorer that suddenly cut out,but before I found this sight I had it put on a diagnostic and it said that 6 sensors were bad,so thinking that sounded pretty crazy to me that 6 sensors suddenly went at the same time I used this site and asked a few mechanics what could be the cause,gave them the code that the diagnostic was giving but none of the answers seemed satisfactory to me due to the discount patagoniafact that the sensors they were referring to were in the transmission andmens patagonia alpine guide jacket black vw24 this was a no start problem,then one mechanic simply said check fuse number 13 under the hood so I did and that was the problem,a simple fuse when all these other mechanics wanted mepatagonia shoes1 to replace sensors that arent cheap
no i havent had any luck with diagnostics,the cruise control doesnt work so i am not able to check the ecm that way,the engine light does come on when you turn the key to the on position and stays lits for a couple seconds then goes out,i had a deisel mechanic come out with a diagnostic machine but he said he could not make any sense of it because his machine was saying my truck is a 2005,he also said that my truck should have two diagnostic ports,one round and one rectangular but mine only has the rectangular,i did replace the starter last year and the first one they gave me going off the year was the wrong one,thestarter that worked was a 1999,so im going to call the dealer with my vin and try to find out whapatagonia discount code brandyts going on there,also i was told that if i unplug the IAP sensor and the truck starts ( but will patagonia discount code for enterpriseonly rev to 1700 rpm) that the IAP sensor is bad,do you have any idea where that sensor is or what it looks like?
Cat Man,first i want to thank you for your patience and time,i cannot seem to find anyone out here with the correct diagnostic machine for my truck,i have been on the phone with cat of ohio and they told me it could be the fuel pressure regulator valve or the IAPCV like you said but that sensor is 190.00,the regulator valve is 90.00,are these two things the most likely cpatagonia employee benefits onlineulprits left,seeing as i cannot find anyone with the correct diagnostic equipment i may just buy the sensor and or the regulator valve,any suggestions?
You will need a 5000 psi gauge. You hook it to the metal output line of the pump that connects to the head. Once it is installed, you crank the patagonia everlong review laptopsengine. Of course the engine will not start. But you must have 4000 psi steady (no fluctuation) while cranking. If the gauge fluctuates or does not make 4000 psi, either the valve is bad or the pump. If it fails the test, I would replace the Injection Actuation Pressure control valve first then retest.
Please be careful. This high pressure oil can be very dangerous.
ok this is dave,the one that has the 7.2 cat 3126b,i have had several diagnostics tests done and still will not start,i replaced both timing sensors,the iap sepatagonia fly fishing new yorknsor that goes on top of the cylinder head and have replaced the solenoid on the heui pump,had the pump tested and it rated at 4200 psi,this was done by a cat mechanic with the correct software,he claims that i am ot getting any voltage or high pressure to my injectors,so now he is saying that i may havea crack in my head which is leading to the loss of pressure,im not buying it due to the auto shutdown my truck has and the fact that the motor was running fine and was not running hot,in fact it has never run hot enough to shut it down,any suggestions,also do you know what the voltage should be at the injectors,dave
I have never seen a cracked head cause low injection actuation pressure. However I have seen a leaking injector cause this. If you have 4200 on the pump that is good.
I would (and have) recommend your site to others I was quite satisfied with the quality of the information received, the professional with whom I interacted, and the quick response time. Thanks, and be sure that I ll be back whenever I need a question answered in a hurry.

used your service this weekend with Trecers help. thank you ,thank you, thank you. replaced an A/C fan motor. Local Auto Zone had part. $15.00 trapatagonia shoes0cer fee and $40.00 for parts, I saved several hundreds of dollers at a shop. i will
9 dollars, 2 hours of my time, and I drove away. Your diagnosis was right on the mark. Thank you so much.
