Someone i am begging you to help me!!!

Sounds Like a fuel problem. Check and clean all the components including the MAF. The vehicle will do a lot of crazy stuff when the computer is receiving faulty information. The one thing that a lot of people forget in the fuel loop is the MAF. The only reason I say to check it is I have had to replace one in a car several times and it behaves different every time. Try unplugging it and see what happens, if it runs or does something different it is a good indicator it is faulty. You can buy a new one for about 130.00 or test it yourself try this post.

I hope this helps and good luck.

We sprayed fuel into the intake though and it still didnt start up...could it still be a fuel problem even when we sprayed fuel directly into the intake?

for sanity i'd just run a compression test but it really sounds like a sensor gave out, as others suggested check Cam position sensor, Crank position Sensor are needed to start along with a few others.

when my CPS went out on the heep, it would start, run for a few then just die 10 minutes later. It couldn't restart right away but if let i sit I could restart and it would be fine for a while. I was able to get the code and knew it was the CPS sensor. One day it decided to die right next to the dealer; one over priced part later all was fine.

It ALWAYS started at first crank and drove great except when accelerating uphills, even low grade hills...it would jerk/shake a little.

jjust for the record that's not fine. It was breaking down un der load

In the upper right of page is a SEARCH feature. Use that in this forum for your sensor research to find out what you need.

I've been wanting to ask why my truck does this sometimes. I never get the shake or shudder until I'm on a fairly steep grade and pushing on the accelerator. Trying to make it downshift of course. Please explain the "breaking down under load"?

When I had a bad MAF on my '94 I could hardly keep it running & it would die easily.

A car with a minor miss wont always do it at idle, it will do it under load, acelerating, hills, braketorqing, etc. Normally means time for a tuneup (plugs and wires)

My 91 developed a buck. Would seem fine after starting then began to buck on acceleration. Turns out zukman changed the spark plugs and leaned on the air horn while changing the air filter. This resulted in a bend and or crack(its plastic) allowing the system to suck air and bypass the maf sensor. Poor thing was trying to have cardiac arrest! After finding the leak(hint rubberhose connect) all is well. Took us awhile to figure it out too. Sneaky little bugger!
A recent trip to the junkyard netted us a shiny metal one.

Ok so MAF and crank or cam sensors should be the next thing to try. As for the searching tip...THANKS...I have been using the search engine!!

Just a question though...could it still be my crank sensor even when we spray gas directly into the intake? Someone said that it should at least run for a few seconds regardless....but that's not true right?? If it doesn't start up with spraying fuel, that just rules out any fuel issue...correct? I've been trying to SEARCH for that info but I haven't been able to find anything.....

UPDATE!!!!
So a "mechanic" came over, told us our computer was "bad". Only thing good about him coming was he was able to actually pull some codes =) Got P1000 and P0232. Googled both, the P1000 seems like I just need to drive it around to clear that code once I fix the other problem code. The P0232...seemed to be the fuel pump relay to me, which was one thing we didnt check! Switched it out with the horn relay and whattayaknow....started up and idled a WHOLE lot nicer, but still ROUGH!

BUT (of course there was a BUT)...as soon as I gas it, it DIES. UGHHH at least it starts and idles!! But why does it cut out when I gas it??

I read alot of posts saying that when they gas it, it runs fine but as soon as they LET GO...it dies. My X is different, idles but once I gas...it dies. Suggestions please???

 

[waianaedawg]

Helpppp

anyone plz???

replaced fuel pump relay...started...a sort of rough idle....press gas...DIES!

what to do next???

I know you said that you replaced the sparks plugs not long ago, but what spark plugs did you replace them with(brand?) Some brands(bosch) seem to not work well with Ford motors and causing a rough idel/missfire. Replace with Motorcraft if possible. NGK's and Champions are okay plugs as well.

When you said it drove fine until the engine was put under a load and started missing out(going up a hill and giving it gas) my first thought was spark plugs. I'd also replace the spark plug wires as well.

You came to the right place and sooner or later we'll help you get figured out. Best thing is to always start with the easiest and most obvious things first before getting to crazy

GOOD LUCK!!!

Edit: Two more things to consider

-Try starting it with the MAF sensor unplugged? If it actually runs without it, then the MAF is bad. (someone work with me on this...)
-Also, didn't see any mention of the TPS sensor(throttle position sensor). Could be bad as well.

 

[waianaedawg]

I really hope someone can help us...our back up car heads just blew and I know its something simple with the Ford (well I hope) but its just finding out WHAT it is!!

To tell you the truth, I dont know what the brand of plugs were. =/ But it gives good and strong spark.

Unplugged the MAF, and same thing...started but as soon as you gas, DIES.
Even borrowed our neighbors MAF (who has a 96 Explorer though) and same thing. Started, idled, DIED.

I forgot to add....it will only start once and idle nicely, once you gas, it will DIE. If you try to start it right back up again, it wont, it will just crank and crank and crank until you basically just kill your battery, which we've done several times. You have to wait for a bit...maybe after 15 minutes, it will fire right back up again and idle fine until you try to gas it.

So my two problems are...1) having to wait at least 15 minutes to start the vehicle (otherwise it will just crank over) and 2)vehicle dying once you press the gas

By the way, havent checked the TPS but I have a receipt from the previous owner who put bought one...receipt says October 2009. You think it would be time for a new one already?

 

[waianaedawg]

I forgot to mention...after its been sitting, itll start right up and idle...gas it, it dies. When it dies, Ill try to start it again...crank and crank and crank...NOTHING. Then you can smell a strong GAS smell!!

About 15-20minutes later....starts right back up again...same thing, idles fine...press gas, it dies.

Please someone...anyone....Im searching and searching the forums for a similar problem but I just cant find anything!! =(

 

[MrQ]

Is it still not throwing any codes? Also don't sit there cranking it all the time like that...its hard on the starter and I don't think that's something you want to replace right now. If it doesn't start after three cranks leave it alone for a bit then come back to it.

Anyways, it sounds like you have a fuel pressure problem. I would check the fuel pressure regulator as you seem to be flooding the engine with gas, thus killing it every time you stomp on the pedal.

The battery has been disconnected several times so I really don't think that the codes that are showing aren't the original code(s) that left me stranded on the freeway. But the codes that came out today were P1000 and P0232.

I haven't been able to drive it since then but it finally starts and idles now, as long as I dont touch the gas pedal. When it dies, I'll have to wait 15-20 minutes before I can start it again, if not it will crank but never start.

Yes, definitely do NOT want to put in a new starter! Thanks for the tip...I'll definitely keep that in mind! Thanks.

As for the FUEL PRESSURE REGULATOR....isn't it part of the fuel pump?? I have a 2000 Explorer XLT SOHC V6.

 

[waianaedawg]

Wishing I could bump my own posts....I really want to fix it today, its my husband and I's wedding anniversary =(

Any ideas anyone?? I'm searching and searching but I can't find anything that relates exactly to my symptoms...

 

[RickOTR]

P0232 FUEL PUMP SECONDARY CIRCUIT HIGH

P0232 means the fuel pump had power when it should have been off. That will trigger sometimes and not be a problem. It's more than likely the fuel pump.

Just for the record....we've resetted the inertia switch a few times trying to diagnose the thing. I've read in a forum that if it was tripped or reset, that it could cause that code to appear.

So with all the symptoms Im having...starts fine on cold starts, idles fine, once I gas it dies and being unable to start it until you wait a bit....that still points to a bad fuel pump??

 

[waianaedawg]

Another question...

I dont smell "rotten eggs", I smell fuel if I decide to try and start it after it dies out the second time....but could my symptoms still be a sign of clogged catalyst converters? I'm trying to search now...I don't have its number one symptom which is the smell but I don't want to rule it out based on that.

I'm tempted to have my husband pull the converter(s) (is there more than one cat on this thing??) and have hiim gut it out. I read performance is better anyway. I live in Hawaii and we don't have to pass an emissions test and theres no laws on the cats. =)
