Hi Everyone my 91 3.0 v6 is starting cold running fine untill it gets to normal operating temp. and then starts stumbling while accelerating ( checked in line pressure guage after stalls and 35 psi. no apperent prop. there ) and dies. Does not want to restart untill cooled off then starts runs and the same shortly again (got it home at least). No Codes, Im thinking coil since I have replaced module and Ecm since at one time it was at a total no start. The ecm replacement had it start right up and run fine but im begining to wonder if it is the same problem coming around again its a reman with my old chip in it, only a month or two old been sitting in my driveway waiting for money to be smoged and sold did all that the numbers were all fine but first real time out up a desent hill and duhhhh. Oh and I did take the dist. out to check it out it was croded on the magnetic points I did clean them all up but the coiled wires below in it did look a little rough nothing disconnected though but making me wonder if thats the breakdown. I did notice that when setting the timing after putting in the new module that when I touched the underside of the dist. around the module area it was screaming hot after a short period of running like almost burned me. Anyway if you can help Thank You, George.

 

Did you put di electric grease on the bottom of the module? If you didn't this is probably the problem. The module gets extremely hot and the grease helps to keep it cool. Hope this helps.

 

Modules can be tested for free at your local parts store.
You may want to replace your pickup coil. You'll have to disassemble your dizzy to get to it.

 

Hi yes I did but Im hearing that that might not be the best thing to use and that there is something else to use that is better and I just can't remember now ( short term memory loss problem need to fix that too )what it was.

 

It's actually called heat sink compound. Dielectric grease works just not quite as well.

 

Pick up coil, thats the unit also that I'm thinking that might be going dead after getting hot. Thanks George.

 

Thats it, Thank You, George.

 

Im in the Golden State ( California about to go broke ) can you give me a name of who can test it we have Kragen, Auto Zone, PeP Boys and Napa auto Parts close to where I'm at and I don' remember any of those able to check them out for me, but they sure can sell you a new one fast with no returns on them.

 

Autozone for sure. Thing is, they tend to fail when they get hot. Have them test the module several times.
They don't seem to get hot on the test bench.

 

Thank You I' will call them right now I think that that's all thats left here I have done Quite a bit of work on this one and havn't spent any lost money on it yet thanks to the help of this site and the people on it. You have a good weekend, George.
