Non Starter...what could be the problem? :-s

hmmm, i so if this does fix it, where would i go from there? im just about to go and try that trick in a min

antrosser · January 15, 2008, 02:22:13 PM

just tried it and sure enough, there was fuel

so what has that eliminated? obviously the fuel pump works...relays? fuses look to be ok? its obviously getting power? im confused where to go now. what would happen if i just permanentle shorted out the FP and GND on the diagnostic box?

Quote from: antrossernoticed that when i took the EGI out the first time (with a screw driver) i had broken the casing and had metal inside touching

So have you bent the copper contacts inside the relay so they are constantly open circuit?

antrosser · January 15, 2008, 03:45:42 PM

looking at it further i only bent the stopper part. when the electro magnet comes on, it should have still pulled the piece of metal to close the circuit. i did bend the stopper bit of metal back out again so it should be working freely (without being a constant circuit)

Mmm, sounds a bit dodgy tbh mate. Relays are fragile things, and dont like being bent with a big rusty screwdriver lol. At least the wiring is ok. You could try a stock ecu. If that fails, it\'s gotta be a relay, fuse or alarm

antrosser · January 15, 2008, 03:51:34 PM

yea ok, ill try changing the ECU and see if that does anything. Ill be sooo ****ed off if my apexi ECU has gone up the duff :-s

Perminantly shorting the FP/GND is not a good idea, i don\'t know if this is running the fuel pump at the full voltage or at the lower via the resistor (if this was the case you would run lean!) You could try and remove the fuelpump relay and see if that was even used in this test by trying again, only takes 20 seconds.

Also do you have the Rx7 workshop manual it details exactly how the fuelpump works

Rough outline would be Circuit open relay > Fuelpump relay > Fuel pump resistor(not always in play) > Fuelpump. (

Also when your trying to start it, keep the accelerator pedal to the floor. This will help it stop flooding, worked fine for me

antrosser · January 15, 2008, 03:55:28 PM

cool. tried starting the car with the fuel pump bridged but still didnt start :-s maybe it did mess up the ECU?

antrosser · January 15, 2008, 04:00:39 PM

unfortunately no dont have the manuals :-( any place i can get them?

RobbieRX-7 · January 15, 2008, 04:24:27 PM

Get them while you can. http://foxed.ca/foxed/index.php?page=rx7manual

antrosser · January 15, 2008, 04:35:52 PM

well ive found the problem! put the stock ECU back in and started up first time!! Goodbye Apexi

im going to write them an email and complain!! no RX7 for a while then!!

RobbieRX-7 · January 15, 2008, 04:39:04 PM

Bummer. Did you ever get it mapped? Might be worth doing a eeprom reset and trying it again

antrosser · January 15, 2008, 04:47:28 PM

how do you do and eeprom reset? i got it partially mapped yea. needed to take it back after i did 1000miles on the rebuild. its done over that now so needed to go back....good job i didnt if all that is wasted!!

RobbieRX-7 · January 15, 2008, 04:51:05 PM

Im not 100% sure how you reset it. I cant give step by step details, but it\'s very easy to do. Just have a mess with the menu\'s. It should say "reset all init data" or something along those lines. You can only do this with the comander though.
