automatic , probably a faulty vehicle speed sensor or manual a faulty sensor in the transmission
check wiring and connections for corrosion , oil , broken wires
Did you just replace the PCM without having it programmed ? Who replaced the PCM ? you ?
PCM Re-Programming
The replacement PCM must be reprogrammed and the crankshaft position system variation procedure must be performed. Refer to the latest Techline information on PCM re-programming and this section for the Crankshaft Position System Variation Procedure.
check spark plug wires and coils for moistore put some lube on the coil wires check for spark after it wont start if itll crank but not start its 1 of 2 thinks no spark or no fuel usally when the coils get too wet they wont allow spark to come through or will cause it to arc
Your battery has nothing to do with this. It sounds like you haven't had anything done in over a year. You most likely need a tune-up, which is normal wear and tear, my guess is the spark plugs and fuel filter need to be changed.
