    Problem 1. Car ran for 3 mins then died and now it only cranks.
    Solution 1. As already stated check fuel pressure then report back.

    Problem 2. No tools
    Solution 2. Rent tools at local Auto Parts Store to test fuel pressure.

    Post up what you find out and Good Luck!

    Check coil, opti, your main ignition fuse and ALL ignition wiring. You've found why its not running - now you have to figure out why its happening.

    The fuel pressure tester can be borrowed from Autozone or Advance auto for a $25 deposit.

    On the ICM, pins A and D are 12V DC, supplied by a fuse. Check the fuse. On an F-Body it's under the hood... don't know about the B-Body.

    Pin C is a ground. It should not have any voltage on it (if you put one lead of the meter on pin C, where did you put the other lead?). Measure ohms from pin B to a good ground. Should read close to "0" (key off).

    Pin B is the pulse signal from the PCM that tells the ICM to fire the coil. Did you measure it with the engine cranking? You have to measure that with the AC Volts scale. What value did you get?

    What year PCM are you using? 2-digit codes would appear to be OBD-1. OBD-2 are 3- and 4-digit codes.

    How did you put the PCM in diagnostic mode? What scanner did you use? DTC 61 is for the A/C system, there is no DTC 62 for an F-Body, is there one for a B-Body?
