Can please someone see if they can send me information regarding the replacement of an ECM for a 1998 Isuzu Rodeo LS with a 3.2 liter engine. The issue seem to have gone like this: I broke down with my car then I had to change the alternator I end up putting a higher amperage alternator from 60 to 70 amps then the rest is history. At the begining it responded well didn't notice anything unusual even after I tested for voltage and amperage; it was all within range then reality sunk in the next day the battery was dead and I bought another battery and to my dismay it was dead again. So I put in a kill switch in the meantime and I left it like that for a while since it's my spare car I was hoping that perhaps I'd make it thru the next winter. So I was kind of disapointed with this alternator and was ready to replace it with another more less amperage so that perhaps the computer would overreact since I was getting different scenarions like as soon as I'd put the main switch and some of the dash lights would go on but they would go off as soon as the car would start and so on. Another issue that perhaps made me realized that I needed to do something was that on ocassion some of the other lights like ABS and Battery lights or Engine would also go on and they soon would also go off but more whenever I would try to accelerate so finally on one of my very few rides around the block to get milk I finally broke down luckily almost infront of my house but not before it was acting like it was loosing power and at times it was kind of doing the same thing. So I guess that I responded a bit too late and today I need another ECM for my car or otherwise I won't be able to drive my car witch has cost me the cost of the car a couple of times over the real value of this car .. Please help with ECM I know I need one because the ECM fuse keeps blowing and I smell smoke from the inside of the car and when I checked the ECM surely enough there was a burned component to the electronic board So a couple of questions before I leave can the ECM electronic board be fix or is it better to just try to replace it with a used one or are there better solutions to this dilema. Txs for your kind response if you have an idea of what I meant but furthermore a solution to this problem would be appreciated. My name is Archie and you can E-mail me at Archdepot@hotmail.com looking forward for some meaningful answers to this pain in the potcket issue.

Did you ever order a new ECM? If so, where did you get it from and did it solve your problem? I need a new ECM too, but after reading tons of bad reviews about various companies that sell re-manufactured units, I don't know which one to trust, if any! Initially PO700 came up on the MIL, so I took it to a shop and paid $110 for the guy to pull the TCM codes (PO602, PO613) They wanted $100/hr to trace wires, check sensors, etc. to further dx. it. Said it could take 2-3+ hrs to 'try to' figure out what went wrong and why. > The dealer said they will need to re-pull codes @$110 and also trace wires, test sensors... > I know by the time either of them are through with me, I'll be out a couple grand minimum! My vehicle only has 35K miles and has had all dealer service as recommended... argh! I'm thinking about ordering a rebuilt ECM and hoping it'll fix the problem. Hopefully, whatever caused my current ECM to fail won't screw up the new one, but with my luck, it surely will! I wish someone could test my ECM to see if it's even bad... God I miss the old days when cars weren't controlled by computers!

look in AllData.. there is a way to test the ECM for your make and model year also try to put your hands on a SNAP ON code reader that shows real time data and can perform individual component tests.. If you cant find one to borrow, pay the 100 bucks to have it diagosed,., sounds like you have spent that already! i hate it too, but sometimes I realize that the 100 bucks is nothing when I have no vehicle to drive, and spent endless hours eliminating things!
