alright swaped a TII into my 87. been jumpin it the whole time cause i was killing the battery and stuff during testing but the battery is fully charged with 650 CCA, new starter but only starts if i jump it with a power source like a car or jump box. http://qik.com/video/32006682

Try another battery.

Maybe the ignition switch is bad? It sounds like when you first start cranking it, the signal to starter is intermittent, like your backing off the key. Plus you have to hit the key a couple times. Mines like that too, but it starts fine.

And, like 10thaniv said, try another battery. At least have it tested. Batteries can appear to be fine by checking them with a voltmeter, but can still be bad. You cant be certain until you have it load tested.

Yea ive taken the battery to shops and tested it and thats where i charged it was from an autopart store. but yea i was thinkin starter trigger wire i cut that off as far back as i could and made a new one cause it was really stale and old.

thats not the battery. sounds like intermittent signal to the starter solenoid. try disconnecting the ignition connector and jumper it to turn the starter and see if problem is still there. could also be a bad clutch cut-out switch

let me know if you need any help, i could drop by and check it out. has it ever run since the swap?

When you not using another battey to jump it.............does the engine turn over using the battery installed in the car? or not. That is not clear from your post.

He included a vid in the first post which shows his attempt to start the car using its own juice. If the Exorcist scared you I would not recommend viewing this video. You have been warned!

Mavman117

lol satch. His video reminds me of my brothers rx7 but his you just have to turn the key a couple times to get it to turn over. After that it starts right up lol.

Ozurdin

lol yea, it does run pretty well, but yea its just cant do it on its own, ive gotten it to struggle on like once on its own. but if i jump it, it starts fine so ima try a battery tomorrow out of my moms car its about the same and then yea i'll start messin with wires but im terrible at that **** so its last step haha.

And GXL just hook up a hot wire to the tab on the starter and start it then?

Near the Main relay is a blue plug. This blue plug might be by itself or plugged into another relay next to the Main relay appropriately named the Starter Cut relay. In this blue plug lies a Black/White wire. This B/W wire runs down to the starter solenoid. Applying voltage to this B/W wire should cause the starter to turn over in an attempt to start the car. This will help to narrow down the problem somewhat especially if the voltage source used to run to the B/W wire is the battery in the car.

[Sounds like either a bum batt or the starter attach bolts are not fully tightened. Probably the batt.

Ozurdin

Yea guys, put my moms battery in there it has 100 more cranking amps than mine but it started perfectly, its wierd mine tests fine tho with voltage and cca idk. but thanks a lot guys!

Ozurdin

alright i bought a new battery today put it in and started fine, drove it around the neighborhood for like 20 min and then went to go fill it up at the gas station and it does the same **** again.

Check your ground and positive cables. Sounds like it could be a cable problem.

Ozurdin

yea thats what im checkin now, i tightened em down really tight and it started up but then on second try it wouldn't do it, something is loose.

Ozurdin

ok the all the connections seem fine but i think its just not getting enough power, cause i can get it to struggle on if i just play with the gas and it'll crank and usually it'll knock the tac out but i went and tightend that and hopefully it should do fine, when i stuggle it on i can turn it back off and turn it on real quick and it'll start a little better and tach will come on. but the power issue, could that be the ignition switch and how do i check that?

HAILERS2

The sound of your starter on that video sounded not good. See what I wrote in my first response to this thread. It sounded like one or both starter attach bolts were loose.......or barring that the brushes inside the alt are worn down to a nub. Remember these are just guesses. No warrenty.

Ozurdin

i did not test the alt but its chargin my battery which is new and the starter is brand new and yea i took it off today and put it back on tight as i can go. but it should be electical, i got a perfect start today i think the ignition switch is goin bad. its givin the starter a poor signal.

Ozurdin

oh and i got my friend to put the volt meter on the trigger switch and i turned the key to crank and im gettin like 11 volts and thats seems weak.

its most likely one of four things (in order of probability imo):
1. Ignition switch - test at ignition switch connector by shorting BRN wire to BLK wire
2. Starter cut relay - test by bypassing the relay, short the two thicker wires in the connector
3. Clutch interlock switch - test by shorting connector
4. Starter - test by connecting battery 12V to the solenoid tab

Ozurdin

oh ok messin around with ignition switch pressin on wires and stuff the car is startin right up first try, about 4 times now ima try it again in the morn but lately the tach's been bouncing a little it working but it wobbles and jumps a little bit.
