Car would start then stall, hard to restart. Went by the haynes manual check coil and icm coil ok icm replaced. Car still wont start, just turns over have fuel but no spark, tried to read error code using jumper but check engine light never blinked or went off. Error code 0 means bad ecm, I need to know if I am correct about the code and if there is anything else I need to try.

I checked the ckp, cyp, tdc sensor as well forgot to mention that it checks out fine on all three for continuity, range from 374-390 ohms and nothing to ground on all 3

Check the wirings going back to the computer-The computer might not be seeing an ignition reference signal due to short or open wire and not firing the coil

Which wires should I check back to the computer. Checked MAP sensor and have no voltage w/key on. Check engine light does not go off when key is turned on, read somewhere the light usually will go off if ECM is ok. Cant read error codes if light wont go off.

Sikpup,

If you jump the service connector to read the codes, what happens? It just stays solid? If so, make SURE that you have properly jumped the service connector, if so, you may have a bad ECM unforunately. You should pull the ECM out and look for burnt capacitors or any burn marks on the circuit board. I have seen quite a few ECM's fail.

However, the fact that you are getting fuel and no spark, tells me that it is a distributor problem. You should double-check all your distributor tests.

Correct the light stays solid.I have triple checked all distributor tests today, replaced the rotor this morn. And it was the only time the check eng. Light went out, tried to start car to no avail, put jumper in and light stayed on. Coil ok, icm ok, ckp, tdc, cyp sensor ok, tried a second dist cap from parts car that ran before I scrapped it last year. Wish I kept the ecm. Thank you for the help!
