I just dont know what the problem is. The car will run for about 10 minutes at a time. I could crank it all day long after that and it wouldn't start. Its not the alternator. I thought it might be a fuel problem and a shop thought I should replace the sending unit. So I had that replaced and an injector. No luck. Anyone have any clues? The car will run fine for those couple minutes and then just die. Im thinking it could be and electrical problem.

Sounds like a bad sensor maybe an 02 since it happens when the engine goes into open loop...check the codes...

Cross these two terminals as shown, then turn the key on. Count the flashes, a 22 will flash as 2 flashes then a short pause, then 2 flashes, if more than one code is stored, the pause will be longer. The codes will display three times and end with 12. Write them down and post here. This connector is right under the middle of the dash...

I keep getting the same flashes from the service light.

It flashes once and then twice. A short pause. Then flashes once and then twice and it keeps doing that until I turn off the key.

Start with the basics, and work your way up, Last tune up was? Wires plugs ALL filters? If all that is ok, check for a stuck EGR, then test fuel pump pressure, If it won't restart, determine what's missing, the engine needs three things to run, Spark at all plugs, gas to all cylinders, and compression in all cylinders, tho an engine may run lacking one in one cylinder, it won't run very well!

Ill check on those things. I just went back out and started the car. It ran strong for about 2 minutes. It then started to run really harsh. I let it run like that for a minute. During this time I would hit the gas pedal and the car acted like it was about to shut off.

Well the scan you did showed a code 12. Which is the last code and it means the ecm has no codes stored, but TPS could be just a bit out of range and cause it, or a vacuum leak, ot the IAC.
