So i finally swapped everything in n go to start car, it cranks. kinda sounds like it out of gas but jus put 3 gallons in it.all of sudden it stops cranking. so i take starter out n hooked few wires to a battery n stater n it spins fine. pt it back in still nothing. All my fuses are good wat else good it be? wring to starter? im getting a new starter tomo...

it might be your ignition switch.

Your car hates your grammar, and is punishing you.

That being said, It could be the ignition system. Either the switch, or the factory alarm system causing problems.

And don't just going buying parts till you know what's wrong with the Rx. Especially if you bench tested the starter and it was fine.

Make sure your starter is grounded... I mean make sure that big ground is going through the top bolt of the starter....
Make sure your battery terminals are tightened all the way.
Make sure that your fuel lines on the driver's side of the car are tightened all the way.
If its not any of those I've got more ideas.

You want to make sure that the starter solenoid wire is sending a voltage signal to the solenoid when the key is turned to start and clutch depressed. On an S5 the starter solenoid gets its voltage from the Clutch Interlock Switch located on the clutch. This switch has two wires, Black/Green wire and a Black/Red wire. B/G has voltage w/key to start, and B/R would have voltage w/key to start "and" clutch depressed. Check this out and see what you get.

If the Black/Green wire at the Interlock Switch does not have voltage w/key to start then the problem "might" lie at the Starter Cut Relay. With key to start the Black/Blue wire at this relay should have voltage on it. If it does then make sure that one of the two Black/Green wires at this relay has voltage w/key to on (one B/G will and the other won't). If one of the B/G wire has voltage w/key to on "and" the Black/Blue wire has voltage w/key to start then check to see if the Light Green/Yellow wire at the relay has a ground on it when the key is to on. If it doesn't then that is the problem. At this relay you could jumper the Black/Blue wire to the Black/Green wire, which does not have voltage on it w/key to on, and this will effectively bypass the Starter Cut Relay. Doing so should cause the B/G wire at the Interlock Switch to have voltage on it w/key to start.

Try this diagnosis before splurging on a new starter as it might not have a thing to do with the starter not turning over especially if the starter turns over when wired to the battery.

ok well i took old starter to get tested,was a bad one. So i bought a new one still wont start. found out im getting no spark. how would i test the igniter coils?

How sure are you that its spark related and not flooded? If its flooded real bad then it will act like its not getting spark but it still is. Rx7 will not deflood themselves after time of sitting like a piston engine will.

Make sure the EGI fuse in the engine bay is good.

Make sure the ENGINE fuse in the interior is good.

Just a FYI: When your cranking the engine with the starter and it does not start........stare at the tach needle and see if it makes small movements when your cranking the engine over. IF the tach needle makes those small movements, that means there IS spark. Can't have one without the other generally speaking.

If I were you I'd buy a can of Starter Fluid from the local auto store. IF you see small movements of the tach needle, then spray for one to two seconds into the snorkle of the air filter assy and then try to start again. IF it now starts, most likely the gas lines AT the engine left side are crossed up. Uncross them and now start the engine.

had buddy crank it n i hooked a spark light to the plugs wasnt getting anything. ima go try it right now see what happens

nopistons2o9

if it was flooded how would i no? n how to fix it?

Car won't start with the EGI fuse or ENGINE fuse blown.

Car won't start with fuel lines crossed up.

EGI fuse feeds the ECU via the Main Relay and also feeds the coil assys and injectors.

ENGINE fuse CONTROLS the Main Relay that feeds what I just wrote above.

Crossed fuel lines cause a no fuel situation. Use stater fluid to prove that or remove the return line on the left of the engine and HOLD the key to START. Fuel should POUR out the hardline on the engine. IF it does not.........fuel lines crossed. Whenever the key is HELD to START the fuel pump should run continuously ...so the just mentioned will happen.

Tach needle movement proves lack of spark all by itself. No timing light needed. No pulling of sparkplug wires required. Just stare at the tach needle. IF it moves.........you have spark and just don't know it.

Flooded series five are unflooded by holding the pedal to the floor while cranking the engine. See owners handbook for series five.

Also check the Black/Yellow wire at the leading coil for battery voltage w/key to on as it powers up the coil. No power no spark!

nopistons2o9

figured out getting no gasoline. opened cover from the fuel pump n took lines off turned key and nothin. Cant even hear the pump turning on. i trying putting starting fluid in intake jus popped few times really loud. so gonna try n figure out more tomo. i am getting spark in leading coil and in the trailing coil im not only in t1 but not t2. first gotta figure out gas problem. gonna try the fuel relays tomo make sure all those work. any other ideas?

Pump will not work w/o key to start unles the fuel check connector is jumpered so jumper this check connector and turn key to on and see if the fuel pump engages or not or did you do this already?

nopistons2o9

havent checked that yet where is the fuel check connector located? and wat do i jump it to?

Should be located near the passenger fender as part of the emissions harness which runs by that area and features two wires, one being Black and the other Brown. Jumper the two wires to themselves (Black to Brown).

nopistons2o9

alright have to try it tomo. will post results

nopistons2o9

alright so was reading up on it. i sprayed starter fluid in and nothin jus loud *** pops. so i jumped the fuel check connector. then turned key on n went by fuel pump n i heard a whinning noise coming from it. but it kept sounding. i replaced the fuel filter, mine was clogged still nothing. so im thinking im not gettin any pressure in my fuel system. gotta get a gauge n see. im pretty sure there are no leaks anywhere. could it jus be my fuel pump?
