97 starts then dies
« on: December 16, 2008, 11:47:40 AM »
 
 hey there,

 i have a 97 sidekick that for the last month was driving fine, but when placed in park would idle for a minute or so then die. i picked up a obd2 reader to see if it was throwing any codes. i keep getting "ERROR", but if i scroll down from there it gives me 5 non-specific codes: P0110, P0100, P0115, P0120 and P1600 in that order. so based on that, i checked out some of these components according to the Haynes manual using an ohmmeter and the sensors seem to be within range and working.
 i also took my egr off to have a look as i have read on here in the past people having similar trouble and it being the egr. it is not clogged and the tube from the egr to intake is fine too.
 i also took the gas cap off and listened for the fuel pump. heard it whirring. and i also started it up and when it died the fuel pump was still running before stopping.
 ok i thought, maybe the fuel filter, so i cracked open the OUT (exit) side of the fuel filter and fuel drained out. i turned the ignition to the ON position and fuel pee'd out.
 checked air filter for clogging (1 yr. old) and mas air.= fine
so the last thing i tried was to unplug the O2 sensor and it seemed to run a lot longer before cutting out.
 oh, and when i get it started, if i throw it into gear real fast i can keep it going with a bit of pedal. but if it is in park or N it won't stay running even with a bit of pedal.

 it's like -6*C outside and about -20*C with the windchill. i'm sick as a dog now from working on this outside in the cold.
 ANY help or suggestions would greatly be appreciated!! ;D

 oh, and it's a 1.6 L 16v with 3 speed auto, 2 door, 4x4 built and drivin in Canada!

If the fuel "pee'd" out of the out side of the fuel filter, I'd say your filter is clogged or your pump is weak. You should have quite a lot of pressure and flow. Somewhere around 30psi is average. I'd say break the line (completely disconnect) at the inlet to the filter and see if you get a "gush" of fuel. If so, filter is clogged. If not... maybe time to get into the tank.

You should also check that the EGR gallery from the intake through to the exhaust is clear. However all of the codes that are being reported are for sensors on the 5V sensor supply. You should check that for bad or dirty connections. Also use a voltmeter to verify that it is at 5V.

 so, when i say "pee'd" out, i wasn't sure if there is a swear sensitive progam on this site. so what i meant to say was "PISSed out", also meaning "gushed out".  It was not a trinkle or a twinkle or even a tinkle  :laugh:  (i have a 1.5 yr. old, i know the lingo ;) )

 and for the egr, if i disconnect the hose that goes from the egr to the modulater there is exhaust blowing out, telling me that the passage is not clogged.

 i'll have to check to see if there is 5v at the appropriate terminals. we got dumped on last nite with snow and i'm still sick as a dog, so i'm hoping it will warm up a bit so i can get out there to check.

 thanks guys and if anyone else has some suggestions feel free to leave them and i will check them too :)

 So it finally warmed up enough to brave the elements and get back at it.
 I decided that i would change the fuel filter as it wouldn't hurt and probably should be done anyways. I also changed the spark plugs while checking out the ignition.
  STILL DOING THE SAME THING!! (but when it did run, it ran better!)

 So the next step, check all vacuum lines, intake plastic for cracks or leaks. NOTHING

 On to the wiring. As i'm going to check for proper voltage at all the critical components, especially the ones that threw a code, i thought that i would do a quick check on all the wires that are touching the body to make sure they weren't rubbing and creating a short. long story short, I wiggle the wires under the main fuse box in the engine bay and the one that controls the Fuel Inj. the black and red one was completely corroded at the connector, it had broken off, but was still touching letting it start up, but not enough to keep it going.
 Soldered on a new connector and took'er for a rip around the block. Feels like i've got more power now too.

 hope this helps someone else out there who seems to have the same problem. thanks guys
