[IMG]rx7[IMG]rx7club[/IMG] club[/IMG] Pleez help! I was trying to test my tps and I had a ****up. I grounded the positive pin(greeen connector )and burned the ground wire some. Then I tried to restart and nothing just a click if I was lucky. I started to look at fuses and I dont know if the tester is bad or if something else needs to be done. I called a junkyard last week and asked if they had any tps sensors and some little interior stuff, the guy said yeah. so I go today and guess what not a rx motr in a car'"/! I am new to rotarys and need info thanx

Not good.

If you mean the three socket check connector for the TPS checkout, well the only hot wire is the black/white wire. It feeds thru the Main Relay and originates at the EGI Comp Fuse in the engine bay fuse box. It also feeds each solenoid on the engine (the EGI Comp. fuse).

The starter does not turn over either????? Just a click??? Or???????????????????????????

Lack of a TPS won't keep a car from starting.

The TPS check connector has three wires. One is black/white, another blue/yellow and the last blue/red. Only the black/white is *hot*.

What kind of *Tester*?

when you say "checked fuses" do you mean ALL the fuses...or just the ones by the dead pedal in the car?

its POSSIBLE that you may have blown the main fuse...however if you are getting a CLICK from the solenoid - then a blown main fuse isn't the case...

How long were you working on the car...is it possible the battery just went low during your messing around?

Brand new battery,alternator. I am using digital multimetr/volts ohm res. The starter is not turning and I was using the 3socket test plug. I did just check the fuses by the dead pedal.

HAILERS

Again, the only hot wire at that connector is the black/white wired one and it gets fed by the EGI COMP fuse in the engine bay.

Determine where the CLICK is coming from. Reach under the car and pull the small wire off the starter solenoid. Now go to START. No click???? Then the starter solenoid MIGHT be bad or it could just be bad connections at the battery terminal. To see if that is the problem, turn the headlights on and go to START. If the lights stay bright then it's not a battery terminal.

If it clicks with the small wire off the starter alternator, then put that wire back on.

With the key to ON, do you get the idiot lights to come on??? They are fed off the ignition switch. No lights might mean there is no power to the ignition switch. It's the BLACK wire at the ignition connector(s) located about a foot from the ignition switch itself.

HAILERS

By the way, do you NOW have 12v on the black/white wire of the Green check connector?

robrxray

Thank you hailers. I didn't have time to keep working and it's cool here in fla. tonight, will be using your suggestions tommorow. Let you know. I do look in forum and faq. But sometimes it's easier to ask here. Also I tried posting pix (avatar) but did not work, that can wait though. I was already to start some projects for car then this +=*& happens

robrxray

tps today, 12v@b/w greenplug wirepin, idiot lights on, headlights on, maybe later get under to pull small wire on solenoid. What about push start? or How do I check egicomp fuse? or should I try to jump starter w/ wire? are there any fusible links on fc3s? Thanx for any info

HAILERS

The EGI COMP feeds the black/white wire on the tps check connector, so you KNOW it's good.

I llike the idea of jumpering the starter from under the car. The old bit where the car is out of gear and you jumper the small blade on the solenoid to the large terminal and the starter turns over. It proves the battery cables are good at least.

IF you have a non theft protected car, you can look under/near the Trail coil assy and you'll see a large BLUE jumper connector. The BLUE half will have a single jumper wire in it.

Anyway, pull the blue half of the connector off and lay it to the side. Now get a long piece of wire with both ends bare, that will reach from the positive post of the battery to the connector you just took the Blue jumper off. Touch the bare end of the wire to the BLACK/WHITE wire in the connector. The starter WILL tuirn over and you don't have to get under the car. If the key is ON the engine might start.

No real fusible links in the car. Just regular fuses.

If you jumper the fuel pump check connector near the right strut tower (yellow, two socket connector that floats around not tied to anything), and you put the key to ON, do you hear the fuel flow thru the fuel rails or hear the fuel pump running? You should.

You could push start it, but I'd be uncomfortable unless I KNEW the spark portion of the starting system worked.

That's the way it works on a series four anyway.

Hail Texas, Hailers thanx again for the info. I am so sick today, I could only manage a1/2 hour on car dx. So the jumping connectors from top is awesome. I will kickass tommorow on this damn cold and electrical problem. All fuel and electrical worked prior to tps error, but that fp connector is good fyi. Let me know if you sell parts. I know a guy about 25-30 miles from here has a goldmine but is pricey.

robrxray

Hailers and everybody else, I did the blue connector jumpwire and nothing but a click. The click sounds like it's coming from under dash? I know the starter relay is undr hood near the connector I just jumped, I could hear the fuel rails filling, try bumping solenoid w/screwdriver?

HAILERS

try bumping solenoid w/screwdriver

YES. I still think you heard the starter solenoid. The black/white wire should have been on the end of the plug and of a fairly large gauge.

Jumpered 12v from the battery positive post to the black/white wire in the plug, with the blue jumper disconnected and set to the side? Yes.

robrxray

Hail yeah, blue connector to side, b/w wire to + battery just light click, thanx for following up. Tommorow, 1st jump solenoid w/screwdrivr, if nothing then what? pull starter to floor test/ solenoid check? what about starter relay/s?

HAILERS

There are NO relays to the starter, UNLESS someone has a Theft protection from the factory. Then there is a relay in place of that Blue jumper plug. The path for the 12v is from the engine fuse box.......to the igniton switch........to the clutch interlock switch........to the Blue jumper and then to the starter solenoid. Jumpering b/t the small blade of the solenoid and the 12v large wire will make the starter turn over. It'll happen when you do it.

When you turn the key to Start and have the headlights on, do the headlights stay bright or go blank when you go to start? They'll dim a bit but not go blank. Should anyway.

Hailers, jacked car couldn't jump w/screwdriver(tightspaces)w/o sparks. Did the old chevy trick and smack the starter/solenoid cases. Then I checked out each fuse on kick panel and found voltage at all. Turned key and 321 ignition, we have fired up. Scared the neighbor kids with the RPM's. Should we archive this problem/repair? Next is back to TPS adjust/replace. I would really like some feedback on putting on exhaust system(stock is on now) also air intake, and struts are the 3 mods I would like to do first. I bought car from original owner, who had great maintenance for car. Oh yeah I'm definitely testing starter/replace. I will probaly do some body stuff and interior. I think close to stock/sleeper is the way on this FC3S
