I'm having issues with my hatch. 92 dx all stock. Replaced the main relay. Replaced the fuel pump. Re grounded the ground for the thermostat housing. Still getting nothing. I grounded out the a7 and a8 from the ecu and the fuel pump primed (read that on another post) and the fuel pump primed! I have no idea where to go from here. Help!

 

What's A7 and A8? Maybe post the link you're referring to.

What exactly does this^ mean. Be precise.

The ECU may be bad. However, more electrical tests should be done to verify.

Unplug ECU connectors A and B. Turn key to ON(II). Measure voltage to body ground at pins A25 and B1.

Turn key off. Measure continuity to body ground at pins A26 and B2.

Post the results.

 

OK. So voltage to body ground.. does that mean hook the multimeter positive to the pins and ground the negative to the body? Sorry if I sound like an idiot but I've never dealt with electrical stuff like this before. Also sorry for the delayed response I work full time and I also have a special needs child. Working on the car has very limited time spaces. Thank you

 

Also how do I test for continuity?

 

after playing around with it for a couple hours I got a reading of 0

 

Played around with what?

A reading of 0 volts or Ohms? And where?

Your lack of information makes it impossible to help you. Put more effort into your posts if you are interested in fixing your car.

Buy a multimeter.

Yes

 

I have a multimeter. I tested for voltage on the A25 as well as B1 I received a voltage reading of zero for both. As for continuity I'm assuming that since there is no power going to my ecu there would be little to no need in an attempt for continuity.
As I've said before when it comes to electrical I'm a beginner.

 

Unplug the IACV connector. Turn key to ON(II). What voltage to body ground do you measure at the Yel/Blk wire pin in the IACV connector?

What voltage do you measure across the two battery posts?






You're assuming there's only one problem.

 

To check continuity with your multimeter, switch it to the Ohm symbol (looks like a horse shoe) within a reasonable scale say middle of the dial, "XX"k or so to start. As it sits you should get a blank/dash/1__ reading. When you touch the leads together you should get a 0.00 reading. That means no resistance AND the circuit has no opens (since you're just touching the leads together it should be obvious that there is no open condition, previously the leads apart would simulate an "open" condition). When you touch the leads to an actual circuit you should get some sort of reading of the amount of resistance whether it's an actual number or a zero reading. If you get a blank/dash/1__ then the circuit is not complete and that is an indication of an open OR the setting is too low on the scale and you need to adjust it.
