After car warms up to temp it shutters and shuts off, after cool down starts aga

Thks for the reply, I will have to find out with my friend if it only dies when driving or not. My OBD2 plug is the only plug that fits the OBD port assuming it is OBD2 compliant. OBD1 is not the correct matching pins. I doubled checked my scanner on my truck and wifes tracker, all workd fine. But I wonder what may be causing the ECU not to send any codes. It does show connected by a solid icon on screen but reads not able to retrieve codes. I did notice the plugs are on the back side of the engine making it hard to see what kind of coil set up it has etc. When I get back with her I will find out more info. THKS AGAIN<I'll keep you posted!

Ok. Well, it sounds like it is definitely OBD2 then. Check the fuses first; In the Fuse Block (in vehicle) CIG - 15A, CLS/PCM - 10A, PCM/IGN - 10A Underhood Fuse Block PCM - 10A Then check the following terminals/wires on the OBD2 Connector under the dash; Pins: 2 - Class 2 Serial Data Line - Purple wire 4 - Ground - Black wire 5 - PCM ground - Black/white wire 9 - UART Data - Tan wire 16 - BATT + (powered from CIG 15A fuse) - Orange wire Let me know what you find.

Awesome response. In a little while I am going back and do a test run with OBD2 pluged in and see for myself what the symtoms are and monitor all gauges. If it doesn't work I'll check the fuses. Thks a million! I'll keep you posted. I did find it is a 2.2 L engine. I'll get back on here this afternoon. We are getting the weather Oaklahoma,is getting now that was awefull.
