When was the last time you changed the spark plugs?
plugs, fuel and air. check for spark. have you reset the ecu??? or looked for engine codes???ChargedTaco said:Okay guys...I need your help.
My 2001 w/50k has a had time starting....
It cranks and starts for half a second and dies...
Every noow and then it starts up completely but I say that's 1 in 30 tries or so.
Anyone experience this problem? any clues?
TIA.
the plugs were changed at 25k....tbrown said:When was the last time you changed the spark plugs?
The spark is there...grumpy said:plugs, fuel and air. check for spark. have you reset the ecu??? or looked for engine codes???
for that 1/2 second of running are you giving it gas??? what happens??
The filter is probably it. Did you put it on backwards or pich the fuel line or anything? Sounds like it's not getting any fuel.ChargedTaco said:The spark is there...
I have disconnected the battery to reset the ecu.
Do you know if any engine codes would be present even if it doesn't throw a check engine light?
What happens is that when I crank it, it sounds like it is started, then when I release the key...it dies.
Oh BTW...I started happening after I changed the fuel filter.(coincedence?)
The filter is on correctly....When it does start, it runs good....getting it started is the hard part.SteveO said:The filter is probably it. Did you put it on backwards or pich the fuel line or anything? Sounds like it's not getting any fuel.
I don't think there is one of those bleed relief things.KRYPTO(dale) said:well..it ran right before the filter change? is there a bleed relief to let air out of the fuel lines on tacos?
ive seen tacos have similar probs when the air intake tube aint on like it should.![]()
Engine wise....headers and an exhaust, stock paper filter.akshunj said:What other mods do you have?
I had starting problems on my '01, but it would start after the second try. It turned out the MAF and the idle control valve were dirty. The oil from the TRD filter coated the MAF and gummed up the idle control valve. After cleaning both parts with electronic parts cleaner for the MAF sensor and intake cleaner for the idle control valve, the truck started perfectly every time. And it ran better, got better gas milage, and idled smoother.ChargedTaco said:Okay guys...I need your help.

I checked the fuel pressure...released the pressure at the rail, cranked it and checked to see if the pressure built up again...looked good.akshunj said:Well you could check the fuel pressure by either using a gauge or pull one of the fuel rails, disconnect spark and have someone crank it while you see if the injectors are spraying. (into a catch pan)
Do you get a strong odor of fuel vapors when it won't start?
I'm gonna check on that. Thanks.SP Jon M3 said:I had starting problems on my '01, but it would start after the second try. It turned out the MAF and the idle control valve were dirty.

Yeah.. small, greenish (hard to tell, I'm color blind) plastic gismo just below the throttle body. Has two phillips screws holding it in.ChargedTaco said:I'm gonna check on that. Thanks.
The idle control valve....that's the part under screwed under the throttle body right?
Interesting.SteveO said:The filter is probably it. Did you put it on backwards or pich the fuel line or anything? Sounds like it's not getting any fuel.
