Need help i dont know what's wrong with my car. everything was fine until yesterday i was at the bank and the car wont start. i was stuck there for maybe 2hrs and then i try it one last time before i call AAA and when i cranked it it started right up and now today i am having the same problem it wont start. i just change the fuel pump out today with the FD one and still no start. can anyone help me out. the car is bone stock.

i did the reset for the ecu and it fired right up. Now i tryed doing the same thing and it's not firing up so i dont know what's up with the car and i am getting pissed.

 

Are you sure your car is not flooding? S4 or s5? N/a or TII? Sounds like it is flooding.....

 

it's a s4 t2.

 

Yeah sound's like it's flooding. Next time it happens pull your EGI fuse and crank for 10-15 seconds with the throttle held at WOT to blow the excess fuel out of the combustion chambers, repeat this about 3 times. It should start afterwards. Worth a try.

 

i have a fuel pump switch.

 

then turn it off when you are running around and get to where you want to go.then click it back on when you decide to go.
look up flooded engine and deflooding methods.
what Mods do you have?Are they stock injectors?
Sounds like you need to get your injectors cleaned.

 

yes i do turn it off. and it's stock injectors.

 

When it won't start, you turn the switch OFF and keep cranking the engine over til it starts. Then you flip the switch back to on.

If you end your driving, just turning the switch to off won't do the job. If you put a fuel pressure gauge on the lines and put the fuel switch to Off to kill the engine, you'll still end up with fuel pressure in the rails. Been there done that.

What you should do is rev the engine to about three grand and switch the cut switch to Off. As you flip the switch to off, floor the pedal. That will completly depressurize the fuel rails. Then turn the ignition to OFF.

Then the next time you start the engine, have the cut switch to OFF and only flip it to ON once the engine is actually being turned by the starter.

Just an opinion. Lots of 'em out there. Probably leaking injector(s) or very low compression.

 

yes i know what to do when i turn it off rev and kill the switch. this car is FU****** pissing me off. and it's not flooding.

 

can anyone local 91770 come and help me out cause right now i am stumped. and dont know what else to do. thinking about getting rid of the car at this point.

 

You need to check for fuel on the plugs. If they're wet and you have spark, it IS flooding. If they're completely dry, you're not getting fuel. Like I said in your other thread about this, jump the yellow test connector on the passenger-side shock tower, and give it a crank. If the problem was the fuel pump wasn't running, jumping the connector will solve it.

 

ok i tryed jumping the yellow connector and gave it a crank and still nothing. i checked the for spark yesterday and it was good so i dont know. i would test for spark again but i cant do it by myself and i dont have a volt meter on me. i just need someone to come by and see if theres anything missing that i didnt do.

 

Pull a spark plug and confirm that they're getting soaked with gas. It's probably got an injector stuck open, so it has no chance of starting.

 

i just pulled the plugs and they where dry. then i put them back and jumped the yellow plug and still no start. i am trying everything and nothing works. i am so fu** tired of tryin to make this **** run. i might sell it when it gets running again. too much problems and i dont really know crap about rx7s

 

If they're dry after you had just tried cranking it, you're not getting fuel at all. Jump the connector again and turn the key to 'ON'. You should be able to hear the pump running, and there should be the sound of fuel being pumped through the lines. Listen carefully in the engine bay & trunk. This will confirm that the fuel pump is or is not running, then you can go from there. If it's not running, you should measure voltage on the fuel pump plug. If is is running, you should test injector voltage at the ECU.

 

admin kill this thread. been fixed

 

So what was it?

 

i think its low compression too.

 

it was lose wires by the ecu.

 

Ground Wire?

 

no it's some of the plugs by the ecu that wasn't tight.
