Wow.......
HI, I'm looking for some suggestions for my car not getting fuel or spark, I've done quite a lot of work on it so far. I went ahead and changed out the old engine,because I thought since a few bearings were burnt out I might have lost compression
But what does compression have to do with fuel or spark?
I know that was pretty big start, but the pistons were done. So after that I've replaced the secondary coil. the dist. module,pick up coil, coolant temp. sensor and other things I can't quite remember .
OK, I'm having a hard time remembering an '85......did this have the "Iron Duke" 2.5 4 cyl or the V6? Did it have a distributor or DIS system?
Anyway the last time I was driving it , I was on the freeway and the engine was cutting off , I have a manual so I tried to keep it alive downshifting it was trying to keep running, but ended up dead. After that I tried cranking it and it almost wanted to go,then it started clicking like the batt. was dead. Now I have fuel going to the tbi but not out ..Not sure if it's because of no spark.Also I have no codes . So if anyone has any ideas please let me know. Thanks.
So if you have no spark and no injector pulse(did you check the harness with a noid light? Do you have power on one leg of the injector harness?), it sounds like you are not getting a reference signal from the ignition module, if this has a distributor.....
So the obvious question is, is the distributor actually turning? Do you have power at the "+" terminal of the ICM? Did you apply the dielectric grease to the back of the ICM before installation? So you have a new ICM and pickup coil installed.....if the distributor turns, with a new ICM and pickup coil, a reference signal should be created...question is, is reaching the ECM? If it isn't, then the injector will not be pulsed by the ECM....if you have an opening between "B" and "+" or "A" and "C", then the coil will not fire.....
