Re: Need mechanically inclined folks"New Update Problem"

But the no power to the injectors is confusing me.

mass flow air meter or some name liek that - its normal, your car works one moment, and stops working the next moment, turn over for days, starts with starting fluid, and NO fuel given to engine (engine cannot sens air flow and does not know how much gas to mix into the stream of air it CANNOT SENSE anymore, so. it stops.


mass air flow meter.

no shit?

I did not know that.

MAF sensors go into OPEN MODE (STUMBLE HOME MODE) when they get no reading.

They will not STOP the car from running....just make it run like shit if they are DOA.

The fuses you are looking for are in the engine bay in a box with loads of wires going to it

Some times you will find fuses rated to 150 amps there connected to alternator suplies

Re: Need mechanically inclined folks"New Update Problem"
had an olds touring sedan, 88 - 3800 motor - woudl NOT start - or start and pop a couple times and die, trust me if I had been able to drive to the 2 miles home, I would have, I tried for 2 hours and got 50 out of gas station... called a wrecker, had it running again next day.

maybe it does theoretically have a get home min operation to it... mine failed.

I've never had one that TOTALLY died as you describe, just because the MAF alone failed..

You may have had something else going on there too.

If you get power to the Ign. Switch and lights etc. then It IS Not the fusable link...


It sounds like your ECM/ECU (Brain) might have Fried...


They seam to be around $150.00 to $175.00 ish and appear to be available after market...

Re: Need mechanically inclined folks"New Update Problem"
OP....I looked up your car.
It may not use a MAF sensor....but instead use a MAP (Manifold Air Pressure) sensor.

Those were the early days of EFI systems in many cars so there are lots of ways manufacturers were toying with doing things. MAP sensor alone could have been MOPARS answer that year.

The MAP sensor could affect the injector flow.

Can you take a pic of under the hood, and post it, so we can see if there is any MAF versus MAP sensor for sure on that thing?
If there is, the MAF would be before the manifold plenum.

Re: Need mechanically inclined folks"New Update Problem"
So i have a car , its not getting power to the electric fuel pump or coil.
The starter will turn over with the key, and the dash lights and all work.

None of the fuses are blown.

I replaced the fuel relays , and auto stop relay.

I smelt something burning like a computer while the key was on by the battery.

I figured out the smell was coming from the engine control module.

It smells like a burn computer board.

Would that be my problem?


damned

Its my daily doom



NEW PROBLEM

Ok What would cause the injectors to not be getting power?

The plug that that leads to the injectors has fire.

The car wants to start when using starter fluid.

So its not getting gas.The fuel pump is working.
I replaced the ecm and its all good.

I cant get any fire on the injector plug while trying to start the car.

Was that the car key on the battery
or was it a tool

Re: Need mechanically inclined folks"New Update Problem"
It is a primative injecting says with map only with speed and throttle position to determined injection amount with a temp sensor in air duct probably near the battery

With the smell of burning check the engine. Earth strap to body
As sometimes the little wire on the engine become the earth wires

Re: Need mechanically inclined folks"New Update Problem"
ok i figured it out.

I had a bad ecm .

Had burnt wires on the injector harness.

The main cause of no gas was Injectors was clogged after i replaced the ecm. I had to take them out and clean them all.

Now I still might have to replace some of the injectors, BUt im going to wait till i run all the bad gas out.

I also removed and cleaned the intake, and all the sensors on the throttle control housing with carb cleaner.

The carb cleaner also worked great on the injectors.

Thanks for the help guys.
