My car acts VERY weird, sometimes it starts right up, other times it does not. I replaced the starter with a junkyard one, and the same thing happens.

I tested the voltage from the starter wire and i get 11.45 volts unplugged from starter.
When I plug the wire into starter and turn key to starter position I only get 5 volts(when it won't start) However if car has been running a while and I shut it off, it always starts up, I did a voltage test when it started and got 9 volt reading.

Anyone have any idea whats up ?

 

Did you try cleaning your battery terminals? I had this same type of problem and that cleared it up immediately.

 

Battery could be going

 

Battery is giving 12+volts I just had it charged fully, slow charge, terminals have no corrosion. Oh and by the way jumping the wire straight to the battery starts car up 100% of the time.

 

So is it the signal wire or the main wire coming from the battery
if its the main wire, just replace it. it is probably coroded

 

Aye replace the wire, mine had the same prob.. i just replaced it with a bigger and better wire and fixed all my starting probs...

 

Didn't test main wires voltage that might be it

 

No, sorry. the power wire. The ground would be a good idea too.
i think the power wire comes from the fuse panel under the hood. i can't remember. just follow it from the starter back to where it gets its main power. Replace that wire.

 

I have one wire coming from the ignition to a small quick disconnect like connection on starter, gets 12v cranked until hooked up, then i have another larger ring style terminal one going from the positive battery to a stud on starter. <didnt test this one. And now that I think of it i don't even remember a ground wire.

 

Battery ground is what i was talking about, sorry. you edited your post before i could reply. Test the main power and let us know what that does. If i keep giving you ideas, i'm afaid I might confuse both of us. lol

 

Just some minor confusion, ideas help greatly though thanks, now the debate im having, go out at 1am and run volt test on the main wire or not.

 

Never good to play with electrical in the dark. i learned my lesson on that the hard way

 

Haha I had voltmeter and flashlight about to go, came and checked post, i'll just go to sleep

 

good idea. let me know how you make out. I'll be on later tommorow to see what happened

 

Ok, main wire coming from battery gets full 12 volts, when cranked it still gets full voltage.
So heres the breakdown,
1. Signal wire cranked unconnected 11.45 volt
2. Signal wire connected/cranked 5.4 volts
3. Main wire 12 volts consistently.
If I jump a wire from positive battery terminal to the small signal wire on starter it starts everytime.

 

Might have something to do with the ignition switch.
Without being there to see it I won't be able to help you anymore.
See what some others think, they might have had a similar experience

 

Come on crx gurus, give me something to work with.

 

Bumpy, help me out

 

I had the <U> exact </U> same problem on my G/f's CRX and it was the ignition switch.

After like 3 months of trobleshooting a friend told me he had the same problem and it was the ignition switch... so I "Bought" one from the junkyard. installed it in like 3 mins and POOF the problem was completely eliminated ever since (7 mons.)


When i opened the old switch up to examine it it was black and burnt looking...

Hope that helps.. it's worth a shot..

 

Check your body grounds. I had the same problem with my daily driver. Make sure you're engines grounded to your battery and to a part on the chassis. The way I corrected this problem was make a 3-way wire. Make sure everythings brought down to bare metal before connecting them too.

 

Fixed my problem myself, I wired in a relay so that the low voltage ignition signal could still send full power to the solenoid.

what size relay did you wire up? can you take a picture and post it up? i have a friend who is having the same problem w/ her crx, we replaced the igniton a while back and seemed to do fine for a while, but it seems like it started up again...

 

You will need a relay:
http://www.radioshack.com/prod...earch
or you can get a relay + socket for cheaper on ebay(socket makes cleaner install)
http://cgi.ebay.com/12-Volt-30...wItem
you will also need:
1.Wire, i used 12 gauge should be able to use smaller wire
2. Connectors: 4 female disconnects, the larger size from radioshack, only need 1 of these if you have a socket. 2 spade connectors, 1 to fit the battery post or a direct power sorce, the other will need to be big enough to fit a clean ground.
3. Tools, a wire crimper/stripper/cutter

Here is what I did.
1. Ran the signal wire to post 85 on the relay
2. Measured/cut wire to run a line from post 86 on relay to a clean ground on chasis.
3. Measured/cut wire to run a line from post 87 on relay to the starter connection, where signal wire originally was.
4. Measured/cut wire to run a line from the battery terminal to post 30 on the relay. Use a fuse here if youw anna be safe, I didn't .
Very easy job, I did it with no relay knowledge just researched and found out how myself.
