A bit of background information: I got an fd with an engine fire, so I took the whole engine bay apart, bought a good used front main harness + battery harness, and replaced them. I then took apart my toasted engine, and had it rebuilt. I bought another complete longblock with blown coolant seals and transfered all of the external parts to the rebuilt shortblock, and put it all back together.

So I try to fire it up and the car gets no fuel. At first I thought it was a bad relay, so i got some other ones and tried testing them, and it still didn't work. So we tried to "jumper" (I believe that is the correct term) the relay connection and it did send fuel through. Odd. So after that, we thought we could at least fire up the car and see how it runs, but it didn't, because we had no spark. My buddy tested the voltage, and to actually see if any spark jumped, but we didn't get anything. The only electrical component I didn't replace was the ecu. Could that be it? The entire engine harness after the pd fire was completely toast, so I think that it might have just shorted out the ecu. Would a bad ecu cause no fuel or spark? If anyone has any ideas, feel free to throw them out.

Oh, and if that does end up being the case, could I get a 94 ecu off of any FD (Ca or non-Ca)? I was reading and I saw that the difference in Ca vs. non-Ca ecu's was on the 93's, and it was something about the electronic egr, but all 94's had that standard, so I could just get a 94 ecu and I should still be able to pass smog, right?

Thanks

Double check all your grounds, and yea --- you will be fine with the ECU swap.

Grounds are all good. Oh, and I need to check the ignitor the next time i'm up there as well.

A bad ECU could cause all kinds of problems. You should be able to have someone local (and in Cali I'm sure you can find someone) drop by to plug in their ECU to test that theory out. I wouldn't just run out and buy a new ECU.

I would also check the ground wires as previously mentioned. There is one that goes to the drivers side of the engine near the bottom. If that's not grounded, the car will not fire.

Also, make sure your CAS connectors are on properly. While that shouldn't keep the car from starting (just running well), just something else to check.

Have you verified that you actually have a Cali FD (i.e. you have the electric EGR switch)? If you indeed do have a '93 Cali FD, then a '94 ECU will be fine.

I actually have a friend coming over on Saturday with his '94 to swap ecu's and test out my theory.

I'll triple check all of the grounds the next time I am up there (Friday) and the CAS connectors.


The car is definitely a Cali FD. I bought the car from the original owner's son and he told me what dealership he bought it from, and he even included the transaction paper. BUT (thanks for reminding me) the extra long block I bought was a '94. And I basically rebuilt the short block and swapped all of the external parts from the '94 over. But that shouldn't make a difference since the electronic egr switch is standard on all of them, right?

I really hope it's something simple like the ECU

Let me know if you need the 94 ECU. I pulled mine out when I put in the PEttit remapped one. Car was running fine on the original ECU.

So it was the ECU... An FD came by today and I asked him if I could use his ecu for a few minutes, so I took it off his car and put it in mine, and sure enough, the car fired up.
