The underhood connections can work by themselves...POS to POS, and NEG to NEG...sometimes dirty/weak connections do not allow the power to transfer fully from the underhood connections...if this is the case then you need to connect directly to the battery in trunk for full power charge...again POS to POS, and NEG to NEG...hope this helps
You will have to take it to the Dealer. You may have burnt out or the "Control Module" needs to be replaced or reprogrammed. Make sure the battery has not reversed polarity also.
how did you disconnect the battery, pos first then neg ? or neg first then pos ?
try starting it and after started, hold your rpm at 1500, for about two minutes, then if still running, drive it to get to.speeds of 40 for about 15 minutes, this is to relearn
if not, disconnect your battery, take the pos and neg cable and touch them together and hold for about a minute, then Connect them back, neg.first.then pos, then follow steps above to.relearn.
Bad connection on cable ends or where they connect to battery. Quick check is if you have a good set of jumper cables, use the jumper cable as a replacement for what maybe the defective one. Hook negative cable good to battery neg. post and then put other side on neg cable to engine ground on block. See if it cranks, if it does than the trouble is on the neg. cable. If not then put positive cable on pos. post of battery. Then put other side of pos. cable on the starter post, try to start. If it cranks then the trouble is on the pos side of cable. Hope this helps.
take a good battery from another car that you absolutely know is good.
Try to prime the motor twice
turn the ignition to start position...do not crank
turn ignition off
turn ignition to start position and try to start
It jumps like any other car. Pos. good battery...Pos. bad battery...Neg. bad battery...Neg. good battery. Then do reverse after it starts. Let old battery charge from new battery with car running if it needs more power to crank over.
what were the 2 fuses for that you replaced? is there a fuse for the e.c.m.? and what do you mean by battery put on reverse? do you mean you hooked pos. to neg. and neg.to pos? or what? need more info.
you will need a 8 mm wrench or a 5/16 wrench to remove the side terminals on the battery. you must disconect the neg. first, then the pos.....when putting the new battery in , you must connect the pos. first, then the neg.
