More Issues..... Car wouldnt stay on after shut off

Ninety5_5Ohh · May 27, 2009

Everyday its something new. Yesterday I left work and drove the car about an hour all freeway then got off and stopped at a buddies house for a few minutes to drop off some parts for his fox. Car was running normal up to this point. I turned off the car and kicked it for about 10 minutes, then went back to the car to start it and it would turn over but would not stay on. ( It wasn't HOT start, like the majority of my foxbodies had ) It seemed like it wasn't getting fuel or spark, or both. After about 5 attempts it fired up but i had to keep it floored in order for it to stay on, and while i had it in gear and driving it would spit and sputter and act as if it just wanted to die. Everytime i pressed in the clutch the rpm would drop right to "0" so I had to keep cranking it everytime i stopped. I got it back on the freeway and drove it about another 20 minutes to my place and when i got off the freeway i pressed in the clutch and it stayed on, drove it on the street about 4 miles and had no problems. It cranked up fine this morning, and I drove it to work ( about 20 miles highway and 5 city traffic ) and seemed to run ok, turned it off at work, and started it again and seemed fine.

Anyone had any clue what happened? One of my buddies said its the computer. Do the computers in these car have like some safety deal that enables the car to run if too hot? Any other ideas?

I do remember when i turned off the car at my friends house it was running warmer than normal. Around 215 220 or so, and the fan was on when i turned it off.

I don't know about this car, its something new everyday, i swear. I should have bough the Bullitt :sad5:

thanks for any help.

Kinda sounds like it could be your pip sensor in the dizzy. I know that will cause some problems like you described. Does it start right up fine everytime when the engine is cold?

check your fuel pressure too.

Fires up like its supossed too when cold, and when warm, and normally when hot. Just this one instance yesterday, other than that i have not had any other problems with cranking and running.

have you pulled codes yet? you don't have to have a CEL to set a code. again it sound like a pip problem with the dizzy.

Ninety5_5Ohh · May 27, 2009

PIP?? I know this is a stupid question, but what does that stand for?

Pulse something pickup i would assume

Id be better off telling you what it does. lol

It uses the vanes that you can see looking in your distributor to control the spark and injectors.

I'm usually pretty good with acronyms but i can't remember this one for anything.

Its the profile ignition pickup. Its the hall effect switchiing device. Its fairly easy to see if you take your cap off the dizzy, its right there youll see the wires connecting to it. If it is dark or black in color it needs to be replaced. One way to test it, if you have this problem again where it wont start, tap on it with a screw driver or something. Just a little force will do it. The car has to be warm for it to work though. If you tap on it and it starts right up, the pip is most likely your problem.

ha... that's what it stands for. thanks with the back up. the older i get the more my CRS (Can't Remember Shit) is kicking in

wow, ill give it a look next time im at the car. Thanks for all the help.

Anyone by chance know if these are expensive ?

CC'S95GT · May 28, 2009

the pip is only about 20 bucks but you have to disassemble the dizzy to replace it out. A whole remanned dizzy is about 120 and it has a warrenty.

Ninety5_5Ohh · May 28, 2009

Nope happens on the foxes too. And im sure other cars as well. They just don't huddle in groups and talk about it. lol
