What's this all about? (Vid)
Been trying to figure out WTH my rig is doing this.
New ignition switch, relays/no change. It has a rough start intermittently too. I was thinking maybe CPS/CKS? Fuel pump ballast resistor? My apologies for the side angle. |
Will it start in neutral ?You getting juice to starter ? NSS ?

I would change the pcm, my wife had one before we met and sometimes the pump would not go and they changed the pcm with one from the juck yard and it started great till that old pcm went out then they just bought a new one and it went till it was rear ended and totaled

Key on key off method check codes . Even if lights not on .

Roger that. Super busy tomorrow, going to the yard wednesday. Ill let you know what happens with the replacement unit. thanks for the input!

Code 12 means power to the ECM has been interrupted in the last 50 ignition cycles or something similar to that. Did you unhook the battery? If not you may have an intermittent wiring problem.
55 means nothing, it's the end of sequence code. |
Pretty big jump to go right to PCM for an intermittent rough idle on starting. Just sayin'.
No diagnostics performed. Parts thrown at it. No known history of tune up parts, inspection of vacuum lines/connections or electrical connections in the engine bay. |

Maybe check/clean the ASD relay? I might do the battery terminals as well just on GP.
