1988 Dodge Dakota are you sure this is the car? 1988? this car had 5 different engine options and ECU. to match them. the PCM (or old ECU) has 1 pin, that is called memory. this pin is hot at all time, battery not dead, or disconnected. its not like todays car, which have complex learn modes, this is 88 year , the first years of EFI (usa cars) why not ask the question from a symptom perspective or state the concern. This memory stores the DTC errors, and short and long term fuel trim. nothing complex here. just basics. now ill answer from inside the ECU. the chip that does this is CMOS, NV RAM. it is a memory chip. (off the shelf) and is held at 12vdc key off by a single external pin. login to ALLDATA.com see 2.5L see pin A41 , that is the memory pin. a red wire. if not 2.5L then please say what you have (under dah, hood) and what is wrong.? "symptoms"

now its not a 1988 but a 1091 olds, and not a Dakota. im totally gobsmacked. what is it, below is Dakota answer if it is an Olds what model car , what engine? ok , the posts come out of order, i answered your first post with a question, and he it is the memory fuse. what engine? 2.2 L (134 cu in) K I4 2.5 L (150 cu in) K I4 2.5 L (150 cu in) AMC I4 3.9 L (238 cu in) LA/Magnum V6 5.2 L (318 cu in) LA/Magnum V8 the 2.5 ECU memory pin as pin A41 red wire and goes to the battery via the main FUSE LINK. i looked at the schematic for the other engine, same link....... id bet dollars to donuts its not bad. there are 3 links, one for Altenator, (is it dead) one for A/C and heater blower, is it dead, and one to drive the input to the ignition swich the ignition goes dead, if that red wire is dead. so is A41, not at 12v at all times. my guess, is you posted to Dodge forum ,why do that? post to OLDS. with engine size and correct year and model OLDS> there are 10 Oldsmobile models, name just 1. like Delta 88?

You might be able to place the truck's rear end on Jack stands. Then put in gear with the brake off. So the rear wheels can spin, while some walks around the truck to help isolate the sound. Once you have a closer area to listen to isolated. A trick to isolate more is to use some thing like a wooden rod and place it on ect. the engine on one end and the other end to your ear. Move it around til the sound is the loudest. If you have a stick shift you can use the gear shift to listen to the trans. while some else is driving as well.

yes might be master cylinder. but also check for any leak in pipeline and wheel cylinders.

Contact dodge parts with the VIN NUMBER

You need to cross reference with your VIN and chevy parts dept

Check your repair manual for ECM voltage and signals! There is no communicatiin between the the ECM advance and the engine beyond idle..........

Use the yellow bottle of HEET to remove moisture from fuel system. Use starting fluid to aid starting.

Possible vacuum leak or sticking idle speed control motor.

open the filler cap. check the level .now bleed the air out. by turning your steering full lock left and right a few times then check the level again if ok refit the cap.

Could be several reasons for this. Plz check fuel filter, air filter and general tune-up items ( I. E.) Spark plugs and wires, air cleaner etc.

go to any parts place and have them check your wiring harness as well as the engines brain box ...a melted hot wire can burn up everything ,,that is a huge expense ..But they can trace your 1 single wire and help you for a few bucks ..Advanced / Auto zone ..God Bless
