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.

Sounds likely friend. You know, you can go down to Advanced Auto parts and they can hook up the computer to it and do a quick test for free.

Re: Need mechanically inclined folks"New Update Problem"
well my knowledge of this is zilch

I usually just take a hammer and smash the fuck outta my car until it runs or dies...

but i can bump the fuck outta this...

i am prolly wrong as I dont know what i am talking about...

but sounds like ur fuel pump burned up...

have you ran it out of fuel lately?

there are several reasons this could happen... my shot in the dark is fuel pump is trashed

I didnt see any inline fuses. The car was setting up for years.

a couple of months ago a guy changed the alternator , then the car drove for a while . Then One day it just wouldn't start anymore.

I thought it was the fuel pump so i changed it . Well I found out now that its not getting power to it, nor getting power to the coil.Everything else is getting power.

If your fuel pump is not receiving power it could be because a fusible link or fuse has blown, the fuel pump relay is not switching or the brain (ecu) is not triggering the fuel pump relay. To test it, pull the fuel pump relay and locate the coil prong and switch prongs on the relay. There is usually a diagram on the relay or the prongs are numbered. Prongs 85 and 86 are for the coil and prongs 30 and 87 are for the switch. Figure out ( carefully ) wich leads on the relay mount correspond with the prongs on the relay. Use a jumper between the switch leads ( 30 and 87 ) and have a friend stand by the fuel tank. Turn the ignition key to the on position and your friend should hear the fuel pump start to run. Don't run the pump for more than a few seconds. If it does not come on you have probably blown a fusible link or fuse. Remember to remove the jumper. If it does come on test the signal from your brain by using a volt meter or test light between the coil leads ( 85 and 86 ) on the relay mount. Have your friend turn the ignition key to the on position and the light should light up ( or the volt meter should show voltage ) for a few seconds then shut off. If this does not happen there is no signal from your ecu. If it does happen replace the relay.

Check the main cables and wires for the fusible link, Under the wire looms or tucked up in the positives + coming from + terminal. It will look like about the size of a 1/3 of a AAA battery. Usually white or off yellow real close to the battery.

No and No. If it is a fusible link you will have to replace it with another of the same size or corresponding size of fuse and a fuse holder. They are made as a throw away item and can not be fixed. It is a thin wire suspended in the plastic and acts as a fuse. Not saying it is your issue but they are very common problems.

If your`e not getting power to the coil or the fuel pump I would pull the distributor cap and check the rotor and the....sorry i`m brain dead right now,i cant think of the name of it...the little wafer shaped modulator that has 2 screws holding it down inside the distributor cap,you cant miss it.These are 2 common causes for not getting spark.

Since it is a 1994 model it only has ODB-I controls....minimally helpful at best in self diagnostics.


Therefore you need to do the legwork.
Use a voltmeter and test the link back from the coil to the ignition module.

Since the fuel pump isn't running either, test the fuse box link leading to the fuel pump and see if you can make it work by putting 12 volts directly through it.

Off the top of my head it looks like you have some burned wire / circuit problem...if you are ABOSOLUTELY SURE all the fuses are ok.
