I got a 93 rx7. It will start 1st time with no problem. After shutting it down and starting it again- it wont crank the motor. I hear all relays clicking. I feel like something prevents starters from getting power to crank the motor. And this is all happening by having this vehicle sitting in garage. Vehicle has not been on road, yet, for over a year. Any usefull info would be great tnx.

Does it start again if you leave it for a while?

zheka

I misted one thing also. even if i disconect the betery for couple minutes and start it agein- still wont start. But if i leave it disconected for couple hours and start it. then i will cnank from the first time.

Also it will help or not. Its automatic, and i just install downpite and mufler on it, cat still in it. also intake box is replased with aftermarket filters.

weird. well GL!

tnx

check your starter-cut relay. more than likely its probably sticking open. driver side kick panel, the only relay in there, it has a blue connector

zheka

Checked the starter-cut relay, I heard it clicking, still wont start. Also replace from another Rx7, still wont start.

RotorDream

is it cranking at all?,

zheka

Will Not Crank At All!! Unless I Have Being Sitting For Over 1 Hour With Bettery Disconected

If you feel you can put it back together...take the starter out, take it appart, clean it, put it back together. See what happens.

Alternately, since you seem to have a buddy w/FD close by, swap starters.

Before you go do all that, turn on your headlights and crank it(easier at night), verify the lights dim...youre checking for the starter's current draw. dim lights power going to it, no dimming then check wiring/starter.

any ideas??????

zheka

read my first concern think the starter is the problem? if it was the starter, would it not start even at first time?

2FAST7S

yeah, thats y i mention it...for whatever reason it may have something to do with getting hot. that would explain the wait time and restart when somewhat cold. If thats the case, maybe tomorrow it will not start at all, hot or cold!

Up to you, do the headlight test its easy, simple and what can you loose?

RotorDream

it could start the first time, and there could be a aproblem with the solinoid on the starter, (such as it sticking open till the circuits broken). if you have access to a lift or a sat of pretty sturdy jackstands, a way you can check if its the starter or not is to start it with the key aa normal, with the key, shut it off, wait like 2 minutes or so and then jumper a +12V to the small clip on the started solinoid, make sure to use a higher gauge wire (around 6-8g). if it tries to crank its not the starter, and you need to trace your starting system, not hard if you have a multimeter, just 3-4 components. just my .02

Sounds like maybe a problem with the field coils inside the starter motor. I'd say quit the headachs and start by replacing the starter. Its easy to change and relatively inexpensive. Buy a cheap 10 dollar multi-meter from your local store and check your battery voltage, too. First drain the surface charge by turning on and off your head lights. Then connect the multimeter and make sure its above 12.4 Volts minimum(fully charged battery should be above 12.6Volts). other wise, replace/recharge your battery also. If that still won't start, check to see if the battery voltage drops when you attempt to crank. If it doesn't you've got an electrical problem.

k tnx for advice guys. I do understand the starter problems... You see i just got my first FD ever. and i even haven't drove it yet. So i though there is something like PSM prevents it from cranking for some reason. Besides there is only 40k miles on the starter. But il check the starter current draw tomorrow. Let you know on what i find.
BTW is automatic and manual starters different from each other?

zheka

ok i check my starter on the car, found that the starter it self works fine with out the problem. Now that i know my starter is working fine all the time. I found that my problem is in the third small wire going from the starter solenoid. If I bypass that wire to ground then starter would work all the time. but is dos not work from the key on the second try, unless it would sit for a wile (1 hour).

have any one had similar starting problems before? is so what was the fix? any ideas on what might be wrong with my?

tried changin battery? or jump start?
i had similar problem where all i hear is a click when i turn the key and it wouldnt crank at all, turns out the positive battery terminal loop were loose and my battery died, got new battery, and problem solved

zheka

when you hear the click, usually is the solenoid will engage, but not enough voltage to actually crank the motor. But I'm at the point where BLACK SMALL WIRE FROM SOLENOID IN NOT DOING IT JOB. for what ever reason it 100% works first time and nothing from second try.


And yes I though it was battery from the beginning, charged battery, try to jump start it. nothing.
like I was saying what ever from the ignition key to the starter small black wire is where my problem.
just no clue what part is bad.

RotorDream

there are only 2 parts after the ignition switch the starter cut relay and the clutch switch, check the voltage at each of those points and youll find where the problem is

when you say small black wire are you talking about gauge or length? the small black wire im thinking of should be +12v when the ignition is in the start position, you shouldnt be grounding any wire on the starter, all "wires" to and from the starter are +12v

zheka

From previous reply that I have seeing in here about possibility of bad starter solenoid. I have replaced my starter by installing new one in. try to start and only had it able to crank once. then I try using testlight in that black/red wire going to the solenoid (with disconnected connector) I have the power when i try to start it . then when i connect it back I have no power.

RotorDream! you mentioned before to check the "starter cut relay" . I replaced that relay, and i replaces the ignition switch. Also It automatic so it does not have clutch switch. And just in case some one thinks it battery, I jump-start it.

Any one have any idea what else it could be I'm sick of trying to find the problem.

how did you check the starter, because the more i read this the more it sounds like a bad starter...

zheka

I just install a new starter in it

What's that starter switch Pettit sells?

SO I try to do diagnostics again today. Now i'm using volt meter. First by checking battery 12.5, (which is ok) attempt to start it, start fine, shut it of. then try again start fine again. on third try solenoid wont engage. check voltage at small gauge wire going to the solenoid only shoving 4-5 volt.
Sounds like i got high resistance in the starting system? or one of the components went bad.
