I acquired a 1991 Mitsubishi Eclipse that was not running for over a year due to the MFI/MPI relay not in the car.

When I got the car, they said the part was ordered, and that I just needed to go pick it up, but that was over a year ago, and the shop had already sent it back, and does not keep record of what it was. The old relay that came out of the car is missing, as the previous owner does not have it anymore.

I did some searching online, and found this wonderful website. I then took the numbers that I found on this site:

E8T08474 (from Picture),

MR224159 - After July 05
MR161519 - Before July 05

and actually had to call a Mitsubishi dealership before ANYONE could help me find the relay. They were able to send me a MPI/MFI relay, but I am not sure it is the correct one for my car. The numbers stamped on the top are: E8T07071. Is this the correct relay?

I plugged this relay in, changed the spark plugs and spark plug wires, put in 5 gal of new gas (cause it was sitting for over a year), and installed a new battery. The starter turned the engine, but the car would not start, and it did not seem to "turn over."

Anyone have any ideas? Do I have the correct part? Any help would be GREATLY Appreciated!

Thanks in advance!

VIN: 4A3CS54U7ME033181
Year/Make/Model: 1991 Mitsubishi Eclipse GS
Body Style: Hatchback 2 Dr
Engine Type: 2.0L L4 FI

I would check for fuel and spark. see if it has both of these. If it does i would do a compression test if it seems to spin too fast it may have bent valves.
 
Looks right. Make sure you have all the ignition components including the transister that bolts to the intake over by the fpr.
 
I don't understand. Where is the transistor that bolts to the intake over by the Fuel Pump Relay? What does it look like?
 
It's a small black plastic part that's bolted to a metal bracket that bolts to the intake. There's one electrical harness clip that connects to it. If you actually look under the fpr on the intake, you'll see it plain as day. If it's not there or not bolted onto the intake (grounded), the car won't start.
 
So here is an update.... I installed everything and now the engine will not turn at all. As if it is stuck. Any ideas?
