So my car started acting up about a month ago at a traffic light, wanting to die and no matter how much i hit the gas peddle it wouldnt go over 3k-4k rpm but little by little i managed to get it home where it finally died. so i turn the key and it cranks but nothing so i got the scanner and got the codes P0171/P0174.....so ive been spending about a month on here reading up on the causes and problems and heres what ive done so far :
checked all fuses in fuse box and all are good
replaced fuel filter
replaced fuel pump (i can hear it turn on and off)
replaced spark plugs
replaced air filter
cleaned the MAF sensor
checked all the boots for tears and are all good
checked the nipple on the fuel rail today and a lot of fuel came out
so i went to jump the car (since its been stopped for about a month) and left the cables on the battery for about 5 minutes and turn the key and NOTHING....fuel pump turns on, engine cranks and turns over, but doesnt start
Can anyone help me??? i dunno what else to do but take it to the mechanic maybe i missed something??
Could it be a bad battery??? i noticed that after i remove the jumper cables, the car doesnt turn over and theres a clicking noise when i turn the key but all the lights and flicker with the clicking noise for like 5 minutes and then dies???
UPDATE fuel lines were crossed when i changed my fuel filter :banghead: car running smoother then ever....thanks for the help guys, surprised no one thought of this tho lol :clap:
I was having the same problems minus the starting, but I found it was a bad DISA valve. Its really easy to replace unfortunately, the part is quite expensive ($100used -$300ish new). I was lucky to find a cool guy on this forum who was selling one for pretty cheap.
My DISA valve crapped out at 102k so its possible that this could be it.
Before turning key on, push throttle pedal to the floor and hold it there, then turn the key and try to crank engine for up to 20 seconds at a time.
Have been seeing many flooded cars in the cold weather lately.
If your try to start car with pedal to the floor and nothing, try the opposite, get a can of Starting Fluid, good 2 second shot into MAF opening once air filter has been removed.
Also if the engine sounds like it is spinning too fast, then you may have to pull plugs, put about a tablespoon of oil in each cylinder, turn engine over a few times, put plugs back and and see what happens.
thanks, i will try this after i replace the battery......also your links were actually the first things i read when i started having this problem, thanks
UPDATE : went to check on the car today and hook it back up with jumper cables, then i realized that i never checked the fuses under the hood so i checked them and they were all good....so 15 minutes go by and i turn the key....all lights come on, fuel pump turns on and i turn the key....engine turns over and doesnt start.
so i decide to check the fuel nipple again and this time no fuel came out of it. so i turn the key to position 2, fuel pump turn on and i give it another go and same thing. i check the nipple again and no fuel......so it has the be the fuel pump relay right???
i have a half of tank of gas, so im not leaking fuel anywhere
Before you go and assume it is the fuel pump relay, check your power at the fuel pump. If you don't have proper 12v, then check your power for the fuel pump working back thru fuses, to relay and then ebox fuse. If you do have power, then you need to go forward and check your fuel pump, and then fuel filter.
Fuel pump and fuel filter are both new....I'm going to jack up the car this weekend and switch the fuel filter lines. Seems like that's a mistake some people make, hopefully that's the case with me
