Great content 💯 Thank you. keep it up brotha 💪
I know this was awhile ago, but did you have any codes come up when this "no start" happened?
No codes were triggered.
What was it the pink and black wire?
White and black wire = 12v reference
ok. I have crank no start. I changed out the fuel pump because I didn't hear it coming on, still no start. I can hear the relay but no prime. do you have any solutions?
You need to check power and ground at the connector of the fuel pump to see if it's getting those two sources.
@@EliTheOBDTech Thanks
I got a top coil wasnt firing. P0300, flashing cel. Swapped coils still no spark on top.. changed out with 3 different modules bc with the new ones the middle coil wasnt firing. Car started ran for a few seconds then rpm started surging and dropping then stalled out and Put back on original module and again top not firing. Replaced crankshaft sensor and harmonic balancer. Car wont start at all.
Possible problems:
*Bad PCM/ECM
*Shorted injectors causing the computer to shutdown the coils
*Jumped Timing chain
Forgot to mention, electrical problems: bad ground or power to the ignition module or wiring problem.
@@EliTheOBDTech thanx for some direction. Next place i was going to test was between the pcm and icm so after u saying that i guess im on the right track. Thanx man.
@@EliTheOBDTech would i be able to rule out shorted injectors and timing chain due to when icm module is changed the no spark event goes from top coil to middle? Not contesting just curious.
@@confidential8738 In that case, yes. Hope you track down your problem, very interesting.
