    My 2012 Honda accord was diagnosed with the u1055 code ECM and the lights are popping up for the TCS, ABS and handbrake light. What do I check and have to fix, to get those light to go away? Can I drive, without issues?

    I believe my ecu/ecm is failing on my 18’ camaro throwing all those codes and giving a list of faulty sensors. Is it better to replace ecu first rather than going down the list and fixing all the list of codes? Ive replaced a couple of the codes like spark plugs, 2 ignition coils, and has fixed the misfires. now giving oil pressure fault sensor. And still idling rough

    For some reason the check engine light does not come on at all on my car, I have a ‘77 porsche 924 and it does not come on despite my car misfiring constantly. Cant even accelerate/ step on the gas without it misfiring and the car wants to cut off and is sputtering. Any ideas on what it could be?

    what would cause a fuel pump to shut off, i have a 2006 ford f150 4.6 it starts fine runs for like 2 minutes then idles down and stalls. the on board system tells me to check gauges, everything seems ok. then i try to star it from that point and it just cranks, no start, but if i turn the ign key to off and it will repeat the run and stall, i took the plug off the fuel pump driver module .and jumped the 2 outer wires and it starts and stays running. can not figure what is going on any suggestions!

    I recently messed up my truck (2003 Silverado 1500) I connected my light bars positive wire to get power and connected it to my f/pmp relay and while I was doing it my truck shut off and ever since no crank , no start then I moved around the fuses and it starts but the dash doesn’t work and it says low power , when I go to turn off the truck it doesn’t turn off the engine keeps running for a minute then turns off . Any suggestions?

    @@8020Media turns out the reason the truck didn’t want to crank and start was because I put to much pressure in the fuel lines and needed to bleed it out got it back from the dealership running but still electrical problems I checked under the hood and a ground was disconnected from the battery.

    My car engine runs just fine but in the last few years when I’ve gone out to start up it like misfires and the engine light is flashing becomes undrivable. I go inside wait 10 minutes and start it up and it runs just fine. It’s done like three or four times in the last few years.

    Check your spark plug wires/boots for any damage if so replace them, also check your spark plugs for any noticeable damage an if there is replace them. If that doesn't work an ya have one on you use a scanner tool to try and see if any codes shows up.
