Well today I went to leave work and I noticed that my tracker started a little harder than normal....I thought that was rather odd. So I went to leave and she just bogged and sputtered a little bit. I limped her home and talked to Zig for a minute. He said he had the same problem and it was plug wires, So I went and got some new wires. That didn't fix it, pulled the distributor, dry as a bone. Pulled the air cleaner, dusty but by no means clogged. This leads me to believe its a fuel problem. Cause it will idle fine and rev ok with no load on the motor but once you try to drive its a no go. I just did the fuel filter not that long ago. So I dont think that is a problem. Which leads me to believe that it is the fuel pump or the fuel pressure regulator. Any other ideas thoughts or opinions are greatly appreciated. GOod thing its nice for some of this week so I can take the bike to work. Hopefully she will be back in action before the week is out.  :-/

It could still have a crack in it. It doesn't take much moisture to cause a problem, but I think you'd have a problem at idle too if it were the cap.
How do the plugs look?
Is there any chance you crimped or bent a fuel line during your body lift?
-
fuel injectors?
a freind of mine had a problem liek this on his ranger, he just got the cleaning stuff that you need and he cleanded his injecctors and the problem went away
-
THe problem seems just too sudden for it to be something like that, cause I just drove about 350 miles yesterday and it never skipped a beat. and i drove to work this morning fine, but the ride home was a different story.
-
hhmmmm, i dunno then, sory i cant be more help

I have the same problem with a 95 16 valve 4 door. Ends up that it is the throttle position sensor. I unplugged it, and it runs better, not as much power or mileage, but it has taken care of the driveability problem. Try unplugging the TPS and see how it drives. If that isn't the problem, maybe it's the computer.
Hope that helps.

Tried it, all it did was trip the CEL....no luck there, thanks though.

hhmmmm all i gotta say is yer truck is lookin good

Did you get bad fuel that day maybe? Could someone have put something in the tank? :-/
How's the exhaust coming out of the tailpipe? Could it be a clogged converter?
The distributor isn't loose and hasn't turned to change the timing, has it?
If you have the single injector in the throttle body, you could pull the air filter plenum off and see if there's a nice conical spray, like there should be, coming out of the injector.

THought it might be fuel, So i went to the gas station and filled up. Doubt somebody put anything in my gas tank but its possible. Also Its a 16 Valve, already checked the injectors. Nothing there. Going to do a filter tonight, cat isn't plugged cause I gutted it. Gonna price out a new regulator and pump today and see how much that stuff is going to run.... :-/ :'(

She don't look that good if ya can't drive her! ;)

This may be a long shot but when you get through all the simple quick and easy fixes check your crank to cam timing.The reason being my youngest sons zuk started acting funny all of a sudden a while back,it started with a hickup(not really a backfire just a little pop) after that it ran like crap. Anyway after hours of doing all the easy stuff we decided it was more serious.What had happened was in its previous owners life the bottem pulley had worked loose and widened the key way slot causing it to be miss timed with the cam pulley.They retimed it but didnt fix the problem Like I said a long shot but when all fails. Good luck M.Z.

hey there i had the same problem awhile back. you can drive sometimes fine but then it will bog out right then be fine again , then bog out. i did every thing plug, wire, filter, checked the cat. so i finally toke it in to a shop, and got my car back in an hour The problem i had was the timming. before you go get all new pumps and stuff do your timming. hope it gets better pierre

try to see if a 8 Valve and 16V fuel pumps are the same. if so george has a bunch of pumps.

When you say "nothing there" you mean problems, not fuel, correct?
How about the O2 sensor(s)?
-
I thought it might be the o2 sensor, I"m going to unplug that and see what it does.
-
Nothing with the o2 unplugged. Didn't trip the CEL either so who knows.

K cool. Priced out a new pump 105 bucks and new pressure regulator is 160....this sucks.
-
The symptoms you have are classic low
fuel pressure, check the filter, and the
fuel PSI, both at idle and trying to drive,
see what happens, My vote is for the
Regulator, fuel PSI should be around
36-43, 36 is correct for TBI systems, I'm
not sure if the MPI system is higher or same.
A quick regulator test is to pinch shut the
return line and see if it runs better, might
not need to pinch all the way as it might
cause it to stall instead of idle.

I was just wondering how one might go about measuring the fuel psi, is there a gauge or something?

I just pulled the tank out and pulled the pump doesn't seem like its bad, the bottom of the tank is clean as a whistle and so is the pump. GOing to goto the junk yard get a pump and a regulator see if that solves anything. Thanks for all the help guys.
-
Getting the fuel PSI is kind of a pain,
you got to tap into the pressure side and
put a guage on it, any guage that reads
to about 50-100 PSI should work but getting
it hooked up is the trick, you might be able to
get a fitting that will fit the threads between the
steel line from the tank and the flex line that
goes to the TBI then you could run a line to a
guage and see what you got.
If I remember right the rail on a 16V has a
PSI port that should be easier to hook up to

WEll i got a pump coming tomorrow, see if that does anything then if its still acting up i'm going to put in a new pressure regulator. Then if that doesn't fix it i'm taking it to a garage cause i have to have my car.
-
DUDE !!!! Your blowing dough before
you know what the problem is, did you
try the pinched line to test the Reg ??
don't just throw $$ at a problem and
hope it's going away, figure it out and
fix it properly :(
Wild
-
Free pump, so im' not throwing money at it. I'm gonna put that in, Then i'm going to do the pinch test. THe pump doesn't look bad I just thought I would try it while the tank is out. Its probably something stupid that I just don't have the know how to figure out. :-/
-
Not sure why, but the computer being bad seems very likely.
Just trying to help.

Thanks Wild! More things to try and hopefully not break 8)

Put the new pump in, runs much better, is almost driveable on the street. But it still has absolutely no low end power until its up above 3 grand then it comes on ok.... The pedal feels weird, it pulls harder if you push it lightly then if you floor it. So that part is confusing me, I think i'm going to break down and take it to a shop. :-/

What if it does nothing when you pinch the line???

Regulator is OK, max PSI is about 60
on the stock pump, there is an internal
pressure blow off valve, it blows off at
60-65 PSI, mine blew off at 63 PSI
did you check the cam timing yet, BTW
I did a little checking on a 16V motor, the
valves did not hit the piston as I turned the
cam over with the piston at TDC, so the 16V
motor should be able to survive a broken
cam timing belt, you might have a timing belt
slip, I had that happen on an Audi I used to
have, it kept "loosing" timing advance (ignition)
so I moved the Dizzy, and it happened again,
so I moved it again, all the time thinking the
computer was going bad, Doh .....
Finaly the belt lost too many teeth and spun
the belt on the crank cogs and she quit in a hurry,
so I replaced the belt, and all was right again.
Check your Ignition Timing, if it's off, you might
want to look into the Cam Timing Belt as the
problem
Good Luck

So I should check my timing. Ok I will do that thanks for all the help I hope i get going again this is really a bummer.
