Have you ever removed the TPS from the throttle body?

i tested the top two which from the diagram was IDL and E2 so i thought, no i havent taken the TPS off the throttle body

Checked your intake tube or the AFM? I don't think the tps is the problem because it will run without the tps(not very good) but not the afm.
I just went through the same sort of thing. However it turned out to be a bad clogged fuel filter.
Could be water in your gas too check the code 12 post.

If you're looking at the TPS while installed on the throttle body, and the connector comes in from the left:


*thanks 4Crawler for the image.

abecedarian

the code 11 specifically relates to the IDL terminal (says so in the code definition) on the TPS and you didn't test it?

scharp

well i thought i did test it i guess i tested the wrong terminals

scharp

well i tested the top two terminals not the bottom two, so i tested to wrong two terminals

abecedarian

you said that already.

and....?

scharp

well i havent tested it yet on the right ones, ima do it first thing in the morning, and i will let you know. and yea i didnt mean to post that twice

abecedarian

Good luck.

If I'm not here to help, I'm sure one of the other YotaTech members will.

scharp

ok thanks for helping me this far. i really appreciate it

my buddy is helpin me troubleshoot the truck and he keeps finding fuel pump. like the fuel pump is not producing enough pressure to start the engine

abecedarian

put a pressure gauge on the fuel line before the regulator and post the pressure.

scharp

will do.

scharp

its got good pressure. but i couldnt put a gauge on it cuz i couldnt find the right adapter to check it

Sounds similar to a problem I was having. I had fuel pressure and spark but it wouldn't even fire. I could get it to start on starting fluid just by spraying some in the intake but that was it. first thing I checked was the injectors. They weren't opening. Test for voltage to ground at the wiring harnes plug with the key on. Should get close to 12 volts. If nothing start working towards the injector resistor or ignition. (injectors are grounded in ecu when told to fire) . If you get 12 volts then crank it with a noid light in and see if it flashes. thats my 2 cents. Hope it helps

scharp

i tried some starting fluid and it still wouldnt start

annoyingrob

Was this motor running before? If so, what did you mess with.

scharp

yea, i havent messed with anything

scharp

i put a noid light on it and its good on the flash. im thinkin injectors. has anyone had injectors take a with 90000 miles?
