Vehicle Dies then starts
Vehicle Dies then starts
HELP!
I have a 93 V-6 Precidia, I changed the distributor twice due to problems, then decided to do the HEi conversion. The problem that I am having now, is that the car will run for approx. 20 minutes, then just die. If I wait around 5-10 minutes, I can start back up and go!
I have changed the external ignitor mod, and resoldered all of the wiring, with no changes!
It's driving me crazy!! Could it be an overheated fuel pump?? or the ECM Box??
Please help

Did you disable the stock ignition module?

Just checking - is the HEI module grounded properly and does it have a good heat sink. Does it hot get hot when running? If yes - it needs to be grounded properly.
If its not the HEI module - then look into the coolant thermo sensor and/or O2 sensors.
Also when its in its no start condition - pull the plugs and do a spark test.

I suggest checking coolant sensors and O2s also. It sounds like you are having a problem with the open loop control since it dies probably about the time it takes warm up the engine. Watch the temp and see if it dies right about or just after the guage shows warm (3 o'clock on the temp guage). Check the codes. If it is the O2 or the water temp it should have stored a code.

Fault codes
Is there an easy way to check stored fault codes? I.E. key on - key off - key on? Or is a reader required? Or testlight and probe?
Open loop O2 sensor should cause the ECM to default......however this wouldn't be the first time I was wrong
Also, overseas Mazdas are equipped with a type of antitheft/disable system, located under the center console. Apparently it has issues with a couple of the solder joints. It will mimic the problems mentioned above.....any input on this theory?

Does anyone know if this system applies to North American MX-3's??
Seems very similar to my problem.

Problem Found!!
After more investigation, I found that the bottom half of the distributor had split and left a large crack in the distributor housing, which when heated, caused the distributor to malfuntion.
Thanks again for everyone's help!
