ok, guys , no more blue smoke form exhaust after adding "STop Smoke". Fuel pressure is staying(thank you jesus).
but.... after 10 minutes of idling, the car dies(its like it runs out of gas) and wont restart until it cools back down.. WHY??? i know i have a code 33, i have had this for a while,, you think the maf finally died?? what else can be, HELP ME.! come on guys my car has been out of comission since June! thanks to Mr. Edelbrock.

 

i can think of a list a mile long ...but two stick out in my mind...the pick up coil and ignition module in the dist, are a good place to start...also i've used a heatgun to track down suspected bad components...like fer instance with the engine running heat the dist with the heat gun....but be careful not to melt wiring

This is a shot in the dark, but maybe when the engine finally heats up and tries to switch to closed loop mode (using the O2 sensor) it shorts out or something. Or maybe your O2 is giving it a value that makes the ECM think that the engine is running way rich so it shuts of the injectors to compensate?

Just throwing out ideas...

genius - yep that's me alright - ha!!

Hmmm, could be a number of things unrelated to TPI (per say),, kinda like RP, one thing pops into mind is the coil could be shutting down,, either because it's going bad, or there is a ground problem. Have you swapped the dist. cap / coil or taken any grounds loose here lately?

new accel cap and rotor,
new accel plugs

 

How many miles on your car and when is the last time your fuel pump and/or fuel filter been changed?

If your fuel pump has never been changed and your car has fairly high miles (over 100,000), it may be that your fuel pump is getting ready to die on you. Fuel pumps seems to die one of two ways: 1) periodic times of low power/stalling or 2) car just won't start. Next time you have a problem with your car stalling, try giving your tank a good wack and see if the car magically starts. If it does, your fuel pump is getting ready to die.

PS: Wacking your tank is not a sure fire way to get the fuel pump working either...sometimes it will give it a couple more "free starts"...sometimes its toast.

 

car has 43,000 original miles on it. fuel filter was changed maybe 3,500 miles ago. i dont think its the fuel pump.

 

Hey Ron, next time it craps out after 10 min. try unplugging your MAF and then try to start it while it's still hot. See if that gets her to start. BTW, when you have this prob. does the engine crank and not fire, or does it just click? Also have you checked for spark when it won't start?

 

well, im up at school and the car is at home with pops,, so the info i gave is pretty much all i know,,, im thinkin maf,
could a bad coil do this?

 

No offense meant here Ron,, just a stab in the dark,, but it happens though,, when you put on the new cap did you move your ground strap over for the coil, or make sure the ground wire for the coil had a good ground (depends on whose coil you're running). If that coil isn't grounded properly it'll act like you've described. However,,, if your lucks like mine,, it won't be something that easy!!!
