Crank no start no gauges?

When you have a crank no-start, chances are it is either a fuel or ignition-related issue. Try this. See if the engine will start if you use starting fluid. If it does and then stalls, we know it is fuel-related. If there is no change, then we need to focus on ignition issues and check for spark at the plugs.

Here is a link that explains how to check for ignition spark:

Try that and let me know the results. Also, let me know what codes you are getting.

Take care,

Joe

There is no fuel or spark in thought i pit that in last message also when the gauges stop working a scan tool will tell me the "PCM does not exist" but like I posted before I have gotten it to start a couple times for 30 minutes or so then nothing for months I'm at a loss on where to go from here I'm thinking of trying to reprogram the PCM and see if that changes anything.

The c codes are always different but I did get one person code let me see if I can locate it again.

I'll have to find it in the morning as I am headed to bed I will let you know.

I would makes sure the battery is in good shape. Also do you have any code number you can share with me?

Please respond

Battery is fully charged or on charger when attempting to start no gauges either way

I can do a gauge sweep as well like I may of mentioned before

p1687


c codes are as follows after gauge sweep
33-11
25-44
27-08
41-44
61-00
aa-01
ac-02
00-00



also as stated b4 they have pretty much always been different here is second and third run

23-09
25-52
27-05
41-52
61-00
aa-01
ac-05
as-05
ae-05
00-00


23-10
25-53
27-06
41-53
6100
aa-00
ac-06
ad-06
ae-06
00-00

not sure if the c codes help or not but there they are

P1687 No Cluster Bus Message, so you are correct, the cluster is bad, I would get a used unit from ebay and plug it in to see if the problem goes away. The CAN BUS goes through the cluster and if it i dead and communication will stop.

i have several of these trucks tried different cluster no change

Okay, lets check the power and grounds for the cluster. Here is a guide to help and the wiring daigrams that show which wires are power and which ones are ground.

https://www.2carpros.com/articles/how-to-check-wiring

Do your testing with the cluster disconnected and the ignition switch on. Check out the images (below). Let us know how it goes

Cluster wires all have power where they are supposed to

Does it matter that it had a aftermarket security system half installed half Uninstalled when I first got the truck so I went ahead and finished removing it and put it back to factory wiring

Yes, that matters, thanks for letting me know, I would remove the aftermarket alarm and return the wiring back to factory. Clear the codes and let me know.

I already did that but b4 I even tried to start it the very first time because I was told there was a crank no start issue with it to start with. That was my step one b4 I messed with ne thing. Would I need the pcm reprogrammed after removing it? Or am I just missing something some where

Before we get to that, can I ask if the engine sounds okay while cranking? Please go over this video which can head us in the right direction.

Please upload an image or short videos in your response

Engine runs great when it starts and runs but most of the time it dont start im jusf gonna take it to a friend of mine and have him figure it out im tired of screwing with it

Okay, did you try the used cluster?

Yes I did i tried a different computer as well with the other computer I have fuel and spark but still wont run and still no fuel or amp gauges but I has fuel and spark so should run u would think ne ways

Yep, if it has fuel and spark with compression it should run, does it make a difference wen you use staring fluid?

Haven't tried starting fluid cuz u dont have ne

So I swapped put the computers and now I have fuel and spark but still doesnt run if I spray starting fluid into intake it will fire but still no gauges and still not running

When you turn the key on without cranking the engine over can you hear the fuel pump running inside the gas tank? Please go over this video again

https://www.youtube.com/watch?v=lXLJbuAZ4CE&t

This will lead us to the problem.

Yes it kicks on also ive jumped the relay over to stay running still wont stay running

It sounds like you have bad gas or the fuel pump is weak, here is a video to help you check the fuel pressure.

https://www.youtube.com/watch?v=kgEixCsqcYM

FUEL SYSTEM PRESSURE 339 kPa +/- 34 kPa (49.2 psi +/- 2 psi)

You can rent the gauge at the auto parts store for free. Please let us know what happens.

Gas is good pulled a fuel pump out of a running truck still nothing getting thru the injectors into the cylinders fuel rail has tons of pressure constant can dump gas down the intake and it will runn for a second or two then die something is wrong with injectors they aren't firing or something

Yep, okay, lets unplug the MAP/MAF sensor and try it again, if the computer does not see the vacuum or air flow it will disable the fuel injectors from firing, here is a guide to help confirm the injector pulse failure,

Let me know how it goes.

Anything on this?
