2000 Dodge Dakota - help with replacing disk brake pads

Q: lotus800 wrote hi electronic engine control wizard please help!! i am having a hard time figure out whats wrong with my 1999 dodge ram with quad cab short bed 1500 4x4 with a 5.2l 318 engine and automatic tranny. my truck would not restart after shutting it off when hot. it cranks but engine doesnt start. it used to take about 30 minutes of cool down before it would run again and now it would take an hour! i already figured out that the pcm is not switching ignition coil circuit on and off causing no spark out of the coil. crank and cam sensor tested ok using a multimeter. guages and tach would not move when it wouldnt start gas and volt guage stays in same postion as when off without moving to correct reading when key is turned on tach doesnt move at all as normally does while cranking. sometimes speedometer says no bus when key is first turned on. after cool down peroid guages finally will show correcting readingsand it will start! just right before trying to fix above no start condition the tranny was acting up. sometimes it would be stuck in 1st gear for all day or in limp mode for all day. it had following codes p1757 p1763 and p1762. after some diagnose work it looked like a pcm is bad after trying new tranny gov press sensor and solonid along with new tranny filter and fluid. above no start condition started shortly after replacing the pcm. the tranny still acted up. now it is acting worst. it is running super rich and idles up and down cold or hot. current codes is as following po122 po117 po107 po112 p1296 and p1764. all codes are similar signal voltage too low. following flow charts carefully pcm is assumed to be defective. i back probed pcm connectors and input singal from all above sensors for the codes are operating correctly. yet my scanner tool shows incorrect reading for sensors. while i wait for your help i will try cleaning pcm ground system do more wire wiggle test and even maybe put in old pcm back in and see if codes are same. seems like sensor voltages which shows incorrect readings on scanner tool change when i bang on the truck espically interior driver area. wires under steering colum looked ok. please help! thanks! have you checked for proper supply voltage to pcm wires fuse ect. have you checked fuse block fuse block power wire that comes from battery and corresponding grounds. i have seen loose wires corrosion shorts all cause erratic pcm problems. if you dont have the right voltage to the pcm it wont have the right reference voltage so all of your sensor signals will be off. good luck. .

tbone wrote you can stick you head in the sand all you want to but it doesnt change the simple fact that global warming is real and is happening now. well gee. we had quite a few hard freezes last year here in phoenix. an area where such freezes are rare. good grief. lol which further demonstrates global warming. perhaps you should do a little research for a change and if you did you would know that one of the symptoms of global warming includes some areas actually getting colder than normal as well as increased rain in dry areas as well as droughts in others. it is not just an increase in global temps. -- if at first you dont succeed youre not cut out for skydiving .

ben in tn wrote so nobody knows what could be causing this or how to correct it recently my 98 durango with 360 auto 4x4 started revving up by 200 rpms instantly when on the interstate or pretty much any other speed as long as the cruise control was on. i first thought the transmission was slipping since when the engine revved up so quickly the forward momentum of the vehicle seemed to stop. just like when the engine revved up the transmission would instantly go into neutral. this intermittent problem would end as quickly as it happened and then start again. like every 30 seconds it would happen and then other times it would go for minutes without doing it.. you could just tell by the tachometer and the loss of forward momentun when it happened.. it does not exhibit any problem as long as i manually control the accelerator. so is some sensor going bad somewhere or how can this be fixed theres around 90k miles on this completely stock durango if that matters. ben in tn my guess is the throttle position sensor. -- ken .
