I've been broke for awhile so I've only just finally been able to try to work on the car some more. It no started back in dec, I've replaced the fuel pump because it decided to crap out roughly the same time. I just today replaced the distributor completely brand new because when I tested the ignitor it failed the test. I was gettin weak spark so I figured it could be it. I replaced the fuel filter as well. I checked the continuity of the mpfi wres I added almost a year ago, they all checked out perfect. I even checked the intake to make sure there wasn't a dead rat in it. I checked the main relay too, it works all fine. I cleaned the 3 grounds I found: battery, valve cover to the chassis. I couldn't find any other ones I would like pictures because I can't even tell where the grounds would be so some pictures would be cool.

 

It's not throwing ANY codes either

 

Anyone? The only thing I can think of is some body wire that doesn't let it start yet doesn't throw a code either and I, for one, do not know of any wires off the top of my head that does so. Its not even throwing an indirect code for something else to give me a slight hint.



Edit: only grounds I found were from the battery to the tranny, and the valve cover to the chassis. Any other ones? Like this thermostat one? Its a sohc zc in a 90ef by the way

 

did you check for spark and fuel ?

 

did u check the starter wire too see if its connected ???is ur batterry charged? isit the correct dizzy'?

 

Yes.

 

are u obd 1?
is ur harnness connected correctly? what ecu?

 

It'll help if I went more in depth huh lol.
Car: 90 std hatch
Engine: sohc zc obd0
Ecu: pm6

Ran fine for 6 months, then I drove it to a store, came out didn't start anymore. We got it to start and idle fine a couple times after replacing the fuel pump situation but the second you would of hit the gas to start going it bog and die.
Now I can't even get it to start anymore, jumped battery or whatever, no way no how.

New fuel filter & fuel pump, new td-02 dizzy. We were getting weak spark previously so we figured it was a failing ignitor. We tested the ignitor even and it failed. We may of been testing it wrong but we checked everything else even and those passed the tests.

Also we noticed today that the #4 injector plug has what smells like fuel on it. No others have that.

 

I know the timing belt isn't fuked up because I can see the belts moving when I try to start it.

 

do you have the engine grounded at the therostat? theres two wires in the engine harness that get bolted to the therostat for a ground

 

That's the one I'm worried about. I didn't notice that earlier but wasn't sure what it was supposed to look like, I'm going to have to check tomorrow. Anymore suggestions anyone? That way I can make it a useful trip out to my car. Currently I leave it in my friends driveway, no room here @ my place.

 

Definately check the thermostat ground cause the main relay or fuel pump grounds there. Does the fuel pump run when u first turn the key? Dying suddenly like that sounds like the distributer coil.

 

Also try another ecu that u know works cause they can crap out suddenly too

 

The check engine light appears for the 2 seconds on startup so I dont think its the ECU.

 

check the thermostat ground and theres a ground on the tranny to the chassie...GL
