Ok ...My girlfired has a 1990 crx (stock, auto) the car has about 176.xxx miles on it. The car has problems trying to start. I mean its funny one day it will start run great. Then in a couple of hours lets say 4-5 hours the car wont start for sh*t. Then ill wait about another half hour and it will start and run like always.....Iam really loseing my mind...i even brang it to my mechanic and he siad i dont know whats wroung...the car started all the time for him... then when i got home took a shower and went out side to start it . it didnt wanna. The batterys new the alternator is good as well. Bottom line the car runs great, just have problems starting . Any opinions are welcome ty

i would say check for some corrosion on the starter terminals....my dads truck is the same way ,thats my best guess./....good luck

 

Typical problems for that old of Honda with that many miles is usually a distributor problem namely the igniter (its in the distributor). If it doesn't make any noises when trying to start it then it will either be a start/distributor/electrical issue.

 

When i turn the key it trys to start but doesnt...the battery is new and the terminals are clean. Its very wierd it wont start but then in a half hour it would start and run perfect. Sorry if i keep repeating my self iam just very stressed out. Cause nobody knows what it is. The cap and rotor are new and so is the distributer

 

did you try cleaning all the grounds...happened to me and sanded the grounds and mounting places and starts all the time

 

most old honda like 88-91 civics or crx have proble with ther mainrelay cuz of the soder goin bad, so check dat, its rite behide da fuse box under da steerin wheel, i have da same proble.

 

^^^^ My car had a problem with the main relay also, would do the same exact thing you are talking about.

 

"main relay"
How to replace: http://www.tegger.com/hondafaq/mainrelay.html

 

maybe its your ignition switch (not likely), starter, or yea your main relay.

 

trys to start and doesn't is very vague

1. Does it, crank smoothly, but not ignite?
2. Or does it start cranking slow, or sometimes just stop cranking entirely. And then the next time, turn over smooth and start.

Answers:
If 1. you'll need to check for engine codes, then spark, then fuel. and tell us more in detail.
If 2. Your starter is dying, its common for them to stick at random. It will get worse and become "every time" LOL

And I guarantee it's not the main relay.
