Car won't Start

[SXM-Accord]

Ok I went through most of the trouble shooting guide, and for what I can figure out everything should be ok.

Sometimes my car wont start, it will click and try and turn over as long as I have the key turned but it wont turn over. If I try for 10 mins or so it will eventually start. What might be the problem? I have changed the sparkplugs and that helped for like a day.

How about the main relay?

[SXM-Accord]

Well the engine bay is immaculate in this car, every wire and harness is in perfect condition and there is no build up anywhere.

What normally is the problem so I can narrow down where to look? Just the starter?

edit: also did a compression test and got 150 150 150 150

I had this same exact problem recently... it was the distributor

[N9netwoAccord]

check the main relay... its that time of the year when the weathers getting warmer... this happened to my car.

when you turn the key on (not to start it, but just to the on postion) listen for the fuel pump priming, if you don't hear it, you know thats your problem.

[SXM-Accord]

yeah when i turn it on but not crank it, i can not hear the fuel pump turning on, so I'm assuming it was going out for a while and has finally crapped out. Is it under the back seat or in the trunk on these cars?

MR is underneath the dash driver side toward the fuse box.

im talking about where is the fuel pump

[NAiL05]

Why do you want to change the fuel pump? The main relay controls the fuel pump. You will benefit changing that since its cheaper and easier to get to.

yeah makes sense since the car starts every now and then, after about an hour it started, so we hurried it up to a local shop and had them check the main relay and the fuel pump.

Its not the fuel pump... its either the distributor or main relay. I went to an electrical shop and that is how I found out. The guy took out the main relay and it was fine. My car had the same exact problem. When it was cold it would have very ver hard starts where i'd have to stay on the key for like 2 minutes straight. Once it was warm it was fine.

Does your car throw the check engine light? Mine did, thats how we found out for sure. It showed 2 codes. Once the car was restarted teh light went away. and it was fine. You can go ahead and waste your time and money on the fuel pump but thats not your problem, I thought it was as well.

[SXM-Accord]

Yeah I know it's not the fuel pump now. I could get the fuel pump to turn on just by turning the key on and off a few times then it would start no problem.

it is your main relay.. what is happening is the jelly or silicon inside the main relay is getting cold and hot which also makes it expand and all that junk.. in turn not getting the full voltage and contact for your electrical system. I know this will sound funny but it might help.. it did a couple of times for me till the damn thing finally just gave out. ... take the main relay out and stick it in the freezer overnight. but if you that far you might just want to replace it .. i was short on funds at the time. It don't take but about 10-20 min to replace.. and when you do..don't bother bolting it back up just in case this happens again.. you can tuck it away behind the dash better. Hope this helps..

Supposedly you can resolder the relays inside to the main board and it will work like new, but it's only like $60-70 for a new one.

[NAiL05]

Yea ONLY 60-70. Resolder ther points inside it and it will be almost the same as new.
