1990 Acclaim turns over but won't fire up. We have intermittent problems that always seem to be solved by disconnecting the battery and then reconnecting it. The transmission slips (sometimes can't get out of 3rd) and that is 'fixed' by turning the car off and back on -- if any of that info helps!
This is the only car we have and we need to move in 2 weeks! Thanks

You need the scanner to turn the light off.Your pcm is throwing an engine code.When you do turn it off it will probably come back on until you fix the problem.Most shops will scan it for free.They can tell you what is wrong.
When you replaced the ECM, did you use a nice coating of di-electric grease? That helps distribute the heat from the ecm so it doesn't over heat. Also check your ignition wiring going from the battery to the ignition switch. Check for any loose or broken connections. A local shop can help you find wire shorts BUT BE ADVISED, Most shops charge a $70 an hour fee to diagnose electric problems. Thats not to fix, only find problems. I highly recommend a self search first.
If I am right, the firing order is,1-3-4-2. With the dissy cap removed, have someone turn the engine over so you can see which way the rotor arm goes. Set the engine to TDC and the rotor arm should point to the No1 cylinder at the start of the firing order. If it rotor points away from the No 1 cylinder then slacken the dissy housing and move the diddy until the rotor ppoints to the No1 cylinder. Now pHT lead from the No1 spark plug to the No 1 possition on the dissy cap. The next lead goes on the next available possition on the dissy cap in the way of the rotation of the rotor then to the No3 spark plug carry on the same with 2 and 4 and that should solve your problem unless you have a different firing order.
Check your battery terminal connections first. The starter draws much more current than your accessory panel and a loose connection at the battery is a good place to start. Corrosion at the terminals can be a problem also. Post your results from this test and we'l go from there.
