why would a 2000 Honda Accord crank but not start sometimes?

Just as Js08016 says, or possibly even a clogged filter sock on the end of the fuel pump, but if you are going to change the pump, get a new filter for it as well. The job is easy enough to do your self through the back seat or the trunk, which could save you a lot of $$. I own this same car and found it to be quite temper mental, especially with the voltage and the fuel & certain parts of the emissions system. There is a service bulletin about an EGV valve and air passage service & repair that involves buying a kit, that has a new EGR valve and a steel sleeve. You remove the EGR valve, upper & lower intake manifolds. Then the air passage needs to be drilled out with a 10MM bit and then tap the new sleeve into the hole. This was developed because the air passages were found to be too small on these engines and the carbon builds up bad and causes a lot of problems with starting and running, and these problems do not always trip the Engine Maint. lights.

If anyone else is having this problem, I changed the pgm-fi main relay a few days ago. My car hasn’t had a problem starting since. If my car starts acting up again with the same problem, I’ll be sure to come here and update, but I’m pretty sure the problem has been solved.

Great tip! Here are some links about that problem https://www.youtube.com/watch?v=QVxOQTSPyGY https://www.google.com/search?q=pgm- fi+main+relay&tbm=isch&tbo=u&source=univ&sa=X&ved=0ahUK Ewjhu5L20OrJAhXDWCYKHSH- DEoQsAQIJg&biw=1024&bih=719#imgrc=_ http://honda-tech.com/honda-civic-del-sol-1992-2000-1/pgm-fi- relay-bad-2544200/

Steve, did you ever have more issues after replacing the relay? I've had the same issue for the last 6 months. No real cause except it tends to do it more often when I try to start the car in the middle of the day. Its lime its not getting a signal to send fuel to the engine

Where is the fuel throttle body on the car?

Where is the fuel throttle on the honda 2000 ex accord

I have this same problem. My 2000 Honda Accord V6 ex only has 84 thousand original miles. I bought this car from relatives in DE. The car is immaculate and has been taken very good care of. I was looking at the maintenance paperwork and saw that this problem had occurred around the 30 thousand mile mark, but was never diagnosed. I have cleaned the EGR valve, run several bottles of Sea Foam through the system. This seems to only happen when there is a huge swing in temps. Today is Febuary 9th and it was in the lower 40s yesterday, this am it was 29. By afternoon it was almost 60 and sure enough it started. I would drive the car smooth as can be. Stop for about 15 min or so come back out start the car, it would crank, but would not run. It is like it is starved of fuel. If I hold the gas down enough to keep it running it will finally keep running. It has given me an engine light in the past with all 6 cylinders misfireing. Today it done the same thing. This is the second time in about 2 weeks it has acted up before that it was over a year.

Update - 02/2018 - My car hasn't had this problem again since I changed the pgm-fi main relay.

I had that same problem and found the the coil fuse had burn marks on it ! Even Honda didnt know what was the problem ! It's a 15 amp fuse on the driver side fuse box ! I replaced it and have had no more problems with it !

I have a 2000 Honda Accord V6 I just bought about 2 months ago. It has 160k but the owner keep it in immaculate condition but it is 18 years old. Anyway about 2 days ago my maintenance light started flashing when I start up the car then goes off which I thought ok it’s probably time for an oil change. Then today I drove home from work and stopped at the store when I came back out I started the car but it died. So I tried a couple more times did the same thing. My first thought was fuel pump but now after reading all these things I am not sure. The other thing that I have seen in the last couple of days is the green key light has been on for a few seconds too. I guess I just need to go get it diagnosed

What is the main reaspn a honda.accofff would miss fire on all 6 cyclinders

tj...did you find out what your problem was...my car is doing the same thing

My car is a 2000 honda accord v6. i drove it out from Indiana to utah with no problems, then when trying to pull out of my uncles house the car died. now i can crank it, but nothing starts. so far ive checked the spark-plugs, checked the air sock,checked the valves and replaced the Main Relay. so far nothing has worked and my car has not been able to start. also when you turn the key, several red lights on the dash board will not go away including the brake light, battery light, and all of the open door lights, in the past that has always been a sign of a bad alternator connection, but it seems pretty clear that the alternator is working fine. it has 280 thousand miles on it, does anyone have any suggestions for what else to check?
