91 Camry ignition problem

[crragland]

Hi, I have a 91 camry, 280,000 miles that died on me again. The last time it died 16 months ago, it turned out to be the ignition module that was bad. But not this time. It cranks fine but no spark. With #1 spark plug at TDC, the rotor points to #1 spark wire on cap. The coil wire resistance in the dist. cap read high so I replaced the cap, wires and rotor. I also replaced the Ignition module with a new OEM one from Rockauto. Still no spark. The coil Ohms good and is only 16 months old, The dist. pickup coil ohms good, I have 12 volts at the primary of coil with ign. switch on. What should I check next? I have had problems with oil getting in the distributer before. Also, where is the ECM located in this car? This is a 3Sfe 2.0 engine

Remove the coil from inside the distributor and check it for cracks.

I did, I removed the dist. cleaned it, removed coil and inspected it, no cracks.

In case like that you should try to see if any codes are present [I suspecting "lack of communication" beween the pick up coils in distributor and ECU] the ecu is located under ashtray wrapped withthe floor carpet

Thanks Doctor J, I will check connections going to ECU next now That I know where it is.

ya got power getting to the plus terminal on the coil?

[crragland]

Yes fredK, I have 12 volts to positive primary terminal of coil with ignition switch on

ok, now put your test lite on the negative and crank the motor over, it will eather blink or go dim-brite real quick and sparks will come out of the center tower, or it will just stay brite and no sparks will leap to your hands
