[scotty nm35]

When my Just stopped working I took it back to the shop and asked for a refund.

Fuel pump perhaps?

[mad082]

or afm. or about 15 other possible things

[ZacZerbst]

take the fuel inlet hose off the engine. turn the car on and see if fuel comes out. also how sure are you there is fuel in the car. i work for racv and you would be supprised by the amount of times we have gone out to a car that the customer thought the fuel pump had died and.the swear they only.just put fuel in it only to get it back to the shop, pull out the pump and find an empty tank. next thing would be to check you afm. im sure someone on here could provide you with the voltages at the plug or if you know some with the same car see if you can borrow it

[Benny123r33]

sorry for the lack of info

soooooo got some tools and done some basic tests..

fuel ok

fuel pressure ok

injector pulse ok

spark ok

even got the injectors flowed and tested just to make sure the wernt blocked

checked to see if the cat had failed and was blocking

problem is still occuring which leads me to belive its an electical problem

any ideas??

if it was the maf it would still run with a lilimt of 2500rpm becoz its in safty mode??

[Benny123r33]

Cas? Tps?

um if it were on of the two how could i test them??

wouldnt the check engine light usually come on for something like that??

Unplug the afm and start the car. Doubt it's the problem though.

[Benny123r33]

will hit back asap cheers guys..

[Benny123r33]

problem solved failed piggy back need a new tune any suggestions??

[Hadouken]

Get a stand alone ecu.

None of this piggy back bs

bingo.

So, the usual advice. Do some research on who are the tuners in your area (you dont want to drive 2hrs + just to drop a car off for tuning of if any troubleshooting is required afterwards) and then work out who is the best and what is their prefferred platform. Of course cost is an issue but you usually get what you pay for and a bad tune = the need for a new motor = prob not worth skimping $200 for the cheaper tuner... In a similar vein, avoid Mine's tuned ECU's. not going into why here.

General consensus is that PowerFC or Z32+nistune is the way to go. Take into account whether having an aftermarket computer puts you in easy defect territory too (if so- nistune)

Hi All,

I'm a noob so I'm not sure if I'm on the right thread or not, but here goes..

Last night I did the mod where you ground out the boost solenoid on an R33GTSt.

Well I read the entire thread on that before attempting it, & then did it as specified.

When I went to test it on my way to work this morning it would not rev over 2500rpm, just kept coughing until i dropped the revs below 2500.

I freaked out (i only just got the car), & put it back to standard, but it still wont rev over 2500rpm..

Have I broken something? Can I fix this?

So far I have reset the ECU as specified (disconnect batt & pump brakes)

I hot wired the solenoid to see if it works (it does)

& I tried running the car with the solenoid grounded & ungrounded.

Still only 2500 rpm..

Please HELP!!!
