To anyone who can help with a feedback on what happened to my car. I was driving my car today and all of a sudenn it shut off......My friend and i had to push it to my house. Anyhow the only thing i can think of was i ran out of gas. But i checked gas gauge it's at half point. So i don't think it's the gas. I think it may be the fuel pump i added 6months ago do you think it went bad? if so how can you tell? Well in the pass everytime i started my car it would crank 2seconds then start. This has been going for quite some times. I first thought it might be the starter but the car shut off while i was driving in fifth gear. Any advices ? the reason why i think i may be the fuel pump ( Walbro 255lp) because the car just comletly shut off during driving. Or the starter. it's not the battery i had my friend jump start it also but didn't work all the electricity is on and seems fine. any feed back would help thank you

 

exact same thing happened to my friends modded wrx, it could be the fuel pump.....

 

did you guys replace the fuel pump? i still have the stock one should i put that one back on ?

 

any one else with the problem in the past?

 

dunno what other mods you have done, if you have an mbc/ebc, turn the boost down and put the stock fuel pump back in and see what happens

 

i don't have mbc.... all i have is a walbro fuel pump, tbe, and and intake also tuned with Ecutek in the past running well for about 6months now just today it shut off completley

 

i cant think of any other creative solutions to the problem, and since you may be running higher than normal boost iwouldnt suggest starting the car with the stock fuel pump in, in case the worst should happen. so maybe try this: pull the fuel pump, hook it up to a power source (away from anything flammable) and see if it whirrs. if you cant hear or feel anything, welp pretty sure its dead. maybe someone else local can lend you their walbro for a few hours to see what the problem is...

 

thank you

 

check battery terminals! Loose terminal could have done it.

 

if its not the fuel pump...what kind of exhaust do you have? i had problems blowing fuses with my HKS hi power where the o2 sensor mounts

 

Fuel pumps usually don't just die - there's a lead time with symptoms of whining and longer cranking (building pressure).
You need to take the car to be diagnosed - this could be many things and judging by the post, I don't know if you're the right person to run through an end:end DX.
I like to go with Achum's Razor and assume something simple like something popped off, disconnected or modification failure.
A dead battery won't do it - your car is on alt while driving.
You need to determine whether it's hydraulic/mechanical or electrical then take the nececassary steps - fortunately, the way you describe it, it doesn't sound mechanical!

 

I had the same issue with mine. Also another local member just had an issue with a bad wire connected to the alternator.

I'd check all wiring and fuses - especially where you have aftermarket stuff, that's been the most common resolution of similar problems around here... good luck bro!

 

I would say a loose ground. Thats my .02

 

Well, if you have had cranking problems for a while now, the fuel pump is probably the best place to start. Have you heard much noise difference in the pump since the cranking problem?

 

you should be able to hear the fuel pump priming when you turn the ignition. if its hard to hear have someone sit in the back seat or take the back seat out
