420A No spark or fuel pump

[chris hall]

I know a lot of guys are trying to find the MFI/MPI relay, here's where it is and what it looks like on a 95 GSX.

I have nothing like any of the photos under the stereo... only plugs that go elsewhere... it's a 95 talons esi...

Might that be because you have a 420A car?

Steve I have no spark and fuel pump doesn't come on when you cycle key also I have no cel either. I just replaced cam and crank sensors and car fired up after that for bout a week but has stopped again. Any help figuring this out would be much appreciated...

Also the low coolant light that looks like the capital done ( on right and is yellow doesn't come on..)

On the 420A the fuel pump and ASD (MFI relay equivalent from the turbo model) relays are on the firewall in engine compartment next to the brake reservoir. Fuel pump is closest then ASD.

I have a hard time keeping the various flavors of the 4G63 power cars straight, so I've avoided retaining any 420A knowledge. From an engine electrical point of view they are completely different. The debugging remains the same, get the wiring diagram and multimeter out and start from the battery checking to see where things stop working.
