Looks like it'* the crank sensor on mine. Not sure if this helps but something worth checking on.
How do you know it was the crank sensor? The shop tell you that or you know cars

You'll have a code from the PCM, if you do the diagnostics I mentioned. It can really save you some trouble. Our cars are OBD1 compliant....the 95 and up are OBD2, and give a bit more detailed info, but nevertheless, it'* amazing what your car can tell you through that little DLC connector . Mechanics don't want you to know that!

Ya know what? now that I understand that diag thing...I did take it in , because I heard the commercial on the radio that they'd do it for free. I took it into two shops and had it on that computer. They said that seeing how the check engine light doesnt stay on , that they cant be 100 percent sure of why its stalling but they said the mass air flow sensor and the throddle position sensor could be the problem...the code said so on the computer, so my husband changed both of them. And a couple days later, it stalled again. I'll try and find out those codes tho.

I just did some searching around and asked question at this board and also at Deathrat'* board. Also if I'm not mistaken I ran the car till it stalled and read the codes also. Still don't have it fixed yet cause I have some other work to get done on the car. But like the others were saying, read the codes and they(the codes) will tell you alot.
I went to a parts store and picked up a code reader, basically all it does is jump the pins that were explained earlier so that the light on the dash flashes the code and this reader also came with a book with what the codes are.

Note to all 87-94 OBD1 Bonnie owners!!!
Not ALL fault codes will generate a Check Engine light!

Codes that do not throw a warning light:

17- Spark reference circuit
23- IAT low temp (throws this if it'* disconnected!)
25- IAT High temp (throws this if it'* shorted!)
31- prndl input circuit
36- Trans shift problem
38- Brake input circuit
39-Torque Converter Clutch problem
61-65 - all Cruise control codes
66- Low AC refrigerant
67- Cruise control
68- Another cruise control
69- Another AC fault
99- power management

So you see, boys and girls, you can have alot wrong with the old bucket of bolts and not know it if you don't read the codes!

Welcome to the board. We have many members that have "connections" to resources and information that will help you out a lot.
Yes there is a way to retrieve codes yourself, but, it only works on models from 1985 - 1993! On 1994 and later models a scanner must be used to retrieve the codes. You can try this way to see if it will work just in case my manual is wrong about the year. Find the "Assembly Line Communication Link (ALCL)" it usually found under the dash near the steering column. Now locate terminals "A" & "B", the 2 uppermost right-hand terminals, "A" is the one the right. You must use a short wire to ground out these terminals. While the terminal is grounded with the ignition "ON" and the engine stopped, the system will enter diagnostic mode. The ECM will display "Code 12" by flashing the "Service Engine Soon" light indicating the system is working. Code 12 is simply one flash, followed by a brief pause, then two flashes in quick succession. This code will flash three times. If no codes are stored code 12 will continue to flash until the ground is removed from the terminal.
After flashing three times, the ECM will display any stored trouble codes. Each code will be flashed three times then code 12 will be flashed again indicating display is completed.
Note: If the trouble is intermittent the engine light will come for about ten seconds then go out. If the trouble is more serious then the engine light will stay on and the trouble codes stored in the ECM memory until voltage is interrupted to the ECM. To clear the codes, disconnect the battery for about ten minutes.
CODES:
code 12: Diagnostic
code 13: Oxygen sensor circuit
code 14: Coolant sensor circuit (high temp)
code 15: Coolant sensor circuit (low temp)
code 16: System voltage high
code 21: Throttle position sensor (TPS)
code 22: Throttle position sensor
code 23: Manifold air temperature (MAT)
code 24: Vehicle speed sensor
code 25: Manifold air temp
code 26: Quad driver circuit
code 27: Gear switch diagnosis
code 28: Same as code 27
code 29: Same as code 27
code 31: Park/Neutral switch
code 32: EGR system
code 33: MAF sensor
code 34: MAF sensor
code 38: Brake input circuit
code 39: Torque converter clutch
code 41: Cam sensor
code 42: Electronic spark control
code 43: Electronic spark control
code 44: Lean exhaust
code 45: Rich exhaust
code 46: Power steering pressure switch
code 48: Misfire diagnosis
code 51: Prom or MEM-CAL
code 52: CAL-PAK
code 55: ECM
code 56: Boost control solenoid
code 63: EGR flow check
code 64: Same as code 63
code 65: same as code 63

I was only listing the codes that don't throw a trouble light.......I thought 1994 was the same diag procedure? It didn't change until 1995 if I understand correctly.....my chilton'* backs this up.
