1997 WRX no go

[spuddling aka IMPRZF]

Hi all, a mate of mine owns a 97 WRX hatch that decided on Xmas day to give up the ghost, which means it also bit into my celebration drinks as I had to go tow him home, any way the car developed a surge when it came on boost, was fine when just cruising but as soon as he got on the gas to overtake etc etc it would cough and splutter like it was out of gas. My mate thought that maybe his fuel gauge wasn't reading right so he stopped at the fuel shop and filled up (with 95) payed for it then went to hop in his car to leave and it wouldn't start. It wound over like it wanted to start but wouldn't fire. When I arrived I checked the CEL and it came up with code 31 which I think is the TPS sensor. Does this sound right? Car was mechanically fine and he had never experienced this problem before and was only doing it for around 10 mins before he stopped to fill it up, also car had just had full service so was deemed to be in good nick, he also rang the shop which had carried out the service and the mechanic seems to think that the TPS wouldn't be the cause of the stoppage, any ideas are greatly appreciated

yep was gonna say Fuel Pump, try that out get walbro intake

Yeah was thinking along the same lines, any way of checking for sure?? Did take the fuel line off before and after the fuel filter and was just trickling out fuel. If that is the case with the fuel pump would that make it throw a CEL 31 or is that a different fault all together??

yeah get that looked at also

Hes blowen his air flow meter.

My old legacy did the same. Popped it and then the lights would all come up and it would turn over like it wanted to start but wouldnt.

Does it have a pod filter?

yeah my car did the same thing, it was the fuel pump, then my coupe did the same thing turned out to be the air filter it was dirty.. could be a number of thing

Yep has a pod filter, will get him to clean his AFM and air filter with some cleaner and see if that helps, fuel pump still winds up when ignition is turned on.

I dont think it needs a clean. I would say you need a new one. Unplug it and try starting it.

I'd check not only the fuel pump,but the entire fuel system,lines,filters,relays,pump-the lot.

When a car throws a fault code for a certain sensor-like the TPS-It pays again to not only check that sensor,but the wiring to and from that sensor,plugs etc.

Same deal with the AFM/Intake.
