420A 97 Eclipse RS MFI issues!

[d_olinger]

So I've been looking for my main relay for forever now and can't find it. I've scoured the forrums and still no luck..

I have the 97 Eclipse RS n/a fwd 420a. I've looked almost everywhere and can't find it. Can anyone help? I know its a very basic question but it about drive me crazy!

NT have an ASD relay instead of the MFI. See 22b here: http://www.dsmtuners.com/forums/attachment.php?attachmentid=23588&d=1075582725

Oh thanks thats soo much help! I've had my interior destroyed looking for it.

So on a different but relevant note, could you tell me if the ASD relay seems to be my problem?

The other night I was driving at a steady 55 mph then suddenly my cars RPMs dropped to like 0 and all dash lights came on, then every thing was normal. The whole ordeal lasted only like 1 second. This happened 2 or 3 more times then my car shut off. I pulled over and tried to crank it but it wont crank. It turns over but wont crank. Also my fuel pump isn't kicking on.

I suppose it could be but they usually are not intermittent (although if it was, that is the end result). Sounds more like a loose wire/connector or perhaps your battery is not tied down so the positive terminal shorts against something when you go over a bump or are accelerating/decelerating.

BTW here is where the components are in your NT: http://www.dsmtuners.com/forums/articles-engine-fuel/100294-2gnt-engine-bay-tutorial.html

Oh wow that tutorial was maybe the greatest reference ever! Thanks! And well I replaced my ASD relay and no luck. Still turning over with no crank. I've looked and different places seem to think it could also be my timing belt? But I'm not sure. Any ideas?

I think you mean it cranks (starter engages and spins engine) but won't start.

First we must know if you have spark. Pull spark plug cable off of spark plug. With gloves on stick a long screwdriver into cable end while holding screwdriver shaft 1/8" away from head. Spark should jump across there when someone cranks engine. If it does check other cables also.

Yeah my bad. And it dosnt have spark..

Assuming you want help, let's check the coil first. Unplug the coil's connector. Now make sure you have +12v on the coil's harness side black-red wire with key on. If so, temporarily connect +12v (eg. from battery) to the coil side connector's black-red wire.

Have the 1 & 2 spark plugs removed with their casings clamped to the head and their cables still on so you can watch for spark.

Connect another wire from the coil side connector's black-blue to ground which will charge up 1 coil. Now disconnect from ground, 2 spark plugs should fire (either 1,4 or 2,3).

Now move the wire to the coil side connector's brown to ground which will charge up the other coil. Now disconnect from ground, the other 2 spark plugs should fire.
