Crank No Start - Honda PGM-FI Main Relay

This is video on crank no start issues on a Honda. A crank no start can be caused by many things including a bad PGM-FI (Programmed Fuel Injection) Main Relay. If the main relay goes bad, it can cut off the fuel injectors and the fuel pump. The exact vehicle in this video is a 2000 Honda Civic LX Sedan. Enjoy!

I spent 2 years getting an associates degree at an auto trade school. Spent 8 weeks in electrical theory and operations class. I have never heard a wiring diagram explained so simply. Thank you. The industry needs more teachers like you.

[wyattoneable]

Once you understand how the relay works the diagnostic procedure becomes much easier. Your a Honda expert!

Glad this video is still up. Been having the crank/no-start issue on my '04 Pilot for a while. Intermittent but happening more frequently. Finally decided to take it in to the dealer. A month-long wait to get in. Searched and found this video. Thought, what the heck, why not try it out. Got the part, installed it, haven't had it happen again. Cancelled the dealer visit the day before. Probably saved me 400 bucks.

Excellent video sir. The diagrams and short precise explanation make this one of the best how to videos on any platform out there. Thank you for sharing!

Been struggling with my 98 crv for ages until I saw this. Thank God for the internet

Thank you for putting the part number in the description! Mine just went on the fritz out of nowhere! I could not find PGM-FI main relay anywhere because they have them listed as fuel pump relays because that's pretty much what they are but I wanted to make %100 sure I got the right part since I had to order online and got it for $24.99 off of RockAuto, which is a Godsend because I start work next week and needed it fast and cheap!

I've just watched the video and it helped me start my client's CRV.

Thanks for this. Honda shut down on me twice. 2nd time in the middle of an 1800 mile trip from Idaho to Alabama. Managed to get it restarted and to a napa. Bought the part..and boom. Rolling again.

YOU’RE THE MAN. TAPPED ON MINE AND IT STARTED RIGHT UP!! 2001 Accord +300k still kicking

[abbstraact]

Thanks for the info!!!
Just had a crank no start symptom on my 99' civic lx after a cold 5 degree night. I took this main relay out, set it inside to see if letting it warm up would do anything. Plugged it back up after it warmed up a bit and she fired right up! time to get a new relay.

[GilTMann-lyfd]

Very well done video. Refreshing to see one done correctly and succinctly.

[joshsmith]

Really good video, COMPLETE information and you made it clear and understandable. Thanks a bunch

[quicksilverlives]

This was explained so well. My 99 civic occasionally won't start, but cranks over well. Then it might be weeks before it happens again. I was thinking that maybe the igniter was bad.

[Longtrailside]

This has the same engine setup as a 97 Honda civic. Great info for me, put this into file for later if needed. Thanks for the great info.

[markstroud]

Very well done. Informative with no frills. Thank you. And please do not forget MAUI.

[comfybubble]

Had that exact same problem where my 93 Del Sol wouldn't start when hot outside. That solved my issue thank you!

[juiceybananas]

Bravo my good man. I do believe you just solved my issue on my 98 Honda CRV. Took off from work and drove a block or so and Blaahhh, no power and 5-10 MPH. Misfire and just suddenly ran horrible. Found the insulation on distributor gone where wires come out of distributor and replaced distributor, cap and rotor and still no run.Spark to cylinders and fuel to filter but didnt check fuel injectors. Great video dude.
