Pull the battery cables at both ends, and reinstall using dielectric grease. Both ends meaning at the battery and firewall/starter etc. Anywhere those cables connect.

Almost starts to sound like the car is going crazy on you. Frequently that is caused by a low voltage or corroded cable situation.

It may not be the answer..it never hurts though. Also check the ECM connections.

The original fuel strainer is half the length of a replacement on a 92, that'* the usual "stalling around turns" problem, typically to the right. I've heard about loose tank baffles causing problems at any time, but have not experienced it.

You can't have simultaneous high and low TPS voltage.

I'm gonna bet that resetting the PCM and cleaning the battery connections and some grounds will fix most of those codes. Dropping the tank and replacing the strainer, and maybe the pump and possibly the tank, depending on what you find when you drop it, will fix the stalling.

Today I will hook up the fuel pressure gauge and drive the car to see what the fuel pressure looks like right before it stalls out.... hopefully this will give me some answers.

Most fuel pressure gauges have about 18" hoses on them. I lengthed mine to about 7 feet. It'* the perfect length to bring out under the hood (by cowl) and into the window of the car.

Tested Mortehls car this way. Pressure was good at slow speeds. Once he got on it the pump weakness showed quickly. At 10psi I hollered..."Let up before we stall!!"

Well I lengthened the fuel gauge like you did as well and drove it today... fuel pressure is not the the issue. It is about 36psi(vaccum line on) at idle and goes up to about 41-42 when gas is applied. You can tell when it dies cuz the pressure shoots up to about 45 and the chime says "ding, ding, ding"

I forgot to mention that the car runs perfect for about 15-20 minutes before it starts up with the stalling.

Think it could be the ECM?

Any new ideas guys?

Hit the battery cables as suggested and I'll knock back another 20oz of soda for more brain power...and ideas

Wasn't it more like, "Wow, look at that, 10PSI! I didn't think it could get that low!" "Let up before we stall!"?

Wow. Good fuel pressure and it'* still happening? J WIkoff suggested looking at the fuel strainer in an earlier post.. but wouldn't a fuel strainer problem be reflected in fuel pressure issues, or no?

As the problem occured if it was fuel, I'd expect to see pressure drop off quick.

There was definately no dropoff in pressure.

Well, now it stalls and makes the transmission act up. Is this the ECM dying?
